Drainage pump selection skills

Drainage pumps used in buildings include submersible sewage pumps, submersible drainage pumps, vertical sewage pumps and horizontal sewage pumps. As the general site of the building is smaller, the displacement is not large, the drainage pump can give priority to the submersible sewage pump and submerged drainage pump, which submerged sewage pump is generally used in important places; vertical sewage pump and horizontal sewage pump required to set the interval The basis of the earthquake, self-filling suction, and occupy a certain site, it is less used in the building.

Drainage pump flow rate should be selected according to life drainage design second flow; when the displacement adjustment, according to the life drainage maximum hour flow selected. Fire elevator pool drain pump flow rate of not less than 10L / s. Drainage pump lift by lifting height, pipe loss calculation is determined, then add a certain free head. Free head should adopt 0.02 ~ 0.03MPa. Drainage pump suction pipe and outlet pipe flow rate should not be less than 0.7m / s, and should not be greater than 2.0m / s. Public buildings should be used for each living drainage cistern as a unit to set up a spare pump, usually should be run interactively. Basement, equipment room, garage flushing the ground drainage, if there are two or more than two drainage pump equipment pump. When the catchment can not set the accident drain, the pump should have uninterrupted power supply; when you can close the drainage pipe, it may not provide uninterrupted power supply, but should set the alarm device. When upgrading sewage and wastewater with larger impurities, the outlet pipes of the submersible sewage pump in different sumps should not be merged and discharged. When upgrading the general wastewater, the discharge pipes of submersible sewage pumps of different sumps may be merged and discharged according to the actual situation . When two or more pumps share one outlet pipe, a valve and a check valve shall be installed on each outlet pipe of the pump. A single pump drainage may occur when the backflow should be set check valve. Do not allow the pressure drain and the building gravity drainage pipe merged discharge. When the submersible sewage pump to enhance large debris, the submersible sewage pump should be equipped with a comminution device; when upgrading with more fibrous waste water, should adopt a large submersible sewage pump. When the submersible sewage pump motor power is greater than or equal to 7.5kW or outlet diameter greater than or equal to DN100, the pump can be used to fix the auto-coupling device; when the submersible sewage pump motor power is less than 7.5kW or the outlet diameter is less than DN100, Tube mobile installation. Sewage collection pond submersible sewage pump drainage, water pumps should be set fixed auto-coupling device to facilitate pump maintenance. Drainage pump should be able to automatically start and stop and on-site manual start and stop. Multiple pumps can be alternately operated in parallel, but also can be put into operation in stages.

Sewage pump structure and performance characteristics

Sewage pump structure and performance characteristics:

Sewage pump is a non-clogging pump, with many forms: such as submersible and dry two, the most common submersible WQ submersible sewage pump, the most common dry sewage pumps such as W-type horizontal sewage Pump and WL vertical sewage pump two. Mainly used to transport urban sewage, manure or liquid containing fiber. Paper and other solid particles of media, the medium is usually the temperature is not more than 80 ℃. Due to the media being conveyed contain easily entangled or bunched fibers. Therefore, the kind of pump flow channel is easy to block, once the pump is blocked, the pump can not work normally, or even burn the motor, resulting in poor drainage. To urban life and environmental protection have a serious impact. Therefore, the anti-clogging and reliability of the sewage pump is an important factor in the pros and cons.

Like other pumps, impellers and pressurized water chambers are the two core components of a sewage pump. The merits of its performance, also on behalf of the pros and cons of pump performance, sewage pump anti-clogging performance, the level of efficiency, as well as cavitation performance, anti-erosion performance mainly by the leaf pump and pressurized water chamber to ensure that the two major components. Here are an introduction:

1, the structure of the impeller: impeller structure is divided into four categories: leaf type (open, closed), cyclone, runner type (including single and double runner) spiral centrifugal four, open Semi-open impeller manufacturing convenience, when the impeller caused by blockage, it can be very easy to clean and repair, but in the long run, under the erosion of the particles will make the blade and the pressurized water chamber inside the wall gap increases, so that the efficiency reduce. And the increase of clearance will destroy the pressure distribution on the blade. Not only produces a large amount of vortex loss, but also increases the axial force of the pump. At the same time, due to the increased clearance, the stability of the liquid state in the flow passage is destroyed, causing the pump to vibrate. This impeller is not easy to transport Large particles and long fiber media, from the performance point of view, the low efficiency of the impeller type, the highest efficiency of about 92% of ordinary closed impeller, lift curve is relatively flat.

2, swirl impeller: The type of impeller pump, as part or all of the impeller shrinking pressure water chamber runner. So no blockage performance is good, through the ability of particles and the ability of long fibers through. Particles flow in the pressurized water chamber is driven by the vortex generated by the rotation of the impeller. The suspended particles themselves do not generate energy and only exchange energy with the liquid in the flow channel. In the process of flow, suspended particles or long fibers are not in contact with the blade, the blade is more wear and tear less, there is no increase in the gap due to abrasion, long-term operation will not cause a serious decline in efficiency, the use of the Type impeller pumps are suitable for pumping media containing large particles and long fibers. From the performance point of view, the impeller efficiency is low, equivalent to only about 70% of ordinary closed impeller, lift curve is relatively flat.

3, Closed impeller: This type of impeller is more efficient. And in the long run the situation is more stable, the use of the type of impeller pump axial force is small, and can be set in the front and rear cover Vice blades. The auxiliary vanes on the front cover reduce vortex loss at the impeller inlet and wear of the particles on the seal ring. The auxiliary blades on the rear cover not only act to balance the axial forces but also prevent the suspended particles from entering the mechanical seal chamber to protect the mechanical seal. However, the impeller of this type has poor non-blocking property and is easy to wind, so it is not suitable for pumping the untreated sewage medium containing large particles (long fibers).

4, runner-type impeller: This type of impeller bladeless impeller, impeller runner is a from inlet to outlet of a curved runner. It is suitable for pumping medium containing large particles and long fibers. Good anti-blocking. From the performance point of view, the type of high efficiency impeller and ordinary closed impeller or less, but the type of impeller pump head curve is steep drop. The power curve is relatively stable, not easy to produce super power problems, but this type of impeller cavitation performance than ordinary closed impeller, especially suitable for pressure on the pump.

5, Spiral Centrifugal Impeller: This type of impeller blades for the twisted helical blades in the tapered hub body axially extending from the suction port. This type of impeller pump also has the role of volumetric pumps and centrifugal pumps, suspended particles flow in the leaves, do not hit any part of the pump, so good non-destructive. Destructive on the transport of small objects. Due to the helical propulsion and the high permeability of the suspended particles, pumps using this type of impeller are suitable for pumping media containing large particles and long fibers, as well as highly concentrated media. In the transport of media destruction has strict requirements of the occasion has obvious characteristics.

From a performance point of view, the pump has a steep drop in head curve, the power curve is relatively flat.

Sewage pump pressure chamber is the most common is the volute, built-in submersible pump and more use of radial guide vane or flow guide vane. Volute spiral, ring and intermediary three. Spiral volute is basically not used in the sewage pump. Ring pressure chamber due to simple structure manufacturing convenience in the small sewage pump used more. However, due to the intermediary type (semi-spiral) pressurized water chamber appears annular pressure water chamber application area becomes smaller. Due to the intermediary type pressurized water chamber and the helical high efficiency and high pressure circular chamber water permeability. Has been more and more manufacturers attention.

Common failures of rotary vane vacuum pumps and their maintenance methods

Rotary vane vacuum pump vacuum technology is one of the most basic vacuum access equipment, which is mainly two (or more) of the rotor slides within the rotor slot (usually radial) and the inner wall of the stator phase Contact, the pump chamber is divided into several variable volume of a rotating variable volume vacuum pump. Has been widely used in metallurgy, machinery, military, electronics, chemicals, light industry, petroleum and pharmaceutical production and research departments, plays an important role in industrial production. However, after using the user for a period of time, the pump body can be found to cause some faults. The main problems are running faults and performance faults. The following two faults and their solutions are described. Rotary vane vacuum pump common failure and maintenance methods To prevent the return oil and reverse the injection, should first open the pump port, according to the provisions of the steering wheel to the memory card with the fuel tank to the fuel tank. At the same time check the oil level should be above the oil standard center, but not full of oil standard, more to be released. Aid to determine the steering method. Pour the sheath on the pump port, such as after the pump was sucked, is positive, was blown off, is the reverse. Normal sound is positive, abnormal sound is reversed. It is recommended to divide the faults into operational faults and performance faults. Operation failure can include pump does not turn, the pump temperature is too high, oil spills, water leakage, the maximum power exceeded. Performance failure can include the ultimate pressure, extreme pressure, suction efficiency, noise, fuel injection, gas town performance, etc. can not meet the requirements or not. 1, the pump does not turn. Unidentified can not open the pump, so as not to aggravate the fault. Can be used to move hands and can not move. A, the pump can move without rotation. The reason can be coupling failure; belt slippage; motor wiring is wrong; motor damage; no power and so on. B, can not be disc or disk is very heavy, the reason can be because the starting pump temperature is too low, the pump oil viscosity is too high; design and manufacture of pump stop to return too much. Too much oil caused by the pump back to the oil too much (too much fuel, or water vapor condensation in the pump, or condensate in the exhaust pipe back to the pump); foreign matter in the pump (intake manifold welding Slag, oxide; Rotor spring pump parts such as debris); Rotary deformation stuck; occured (copper sleeve, rotor, the wall, pump cover, stator, bearings). 2, the pump temperature is too high. Refers to the lowest measured near the exhaust valve exceeds the maximum oil temperature specified in the manual. As the pump temperature will cause a substantial decline in the viscosity of the pump oil, and right to use the saturated vapor pressure pump oil increased pressure to pump the ultimate pressure and suction efficiency decreased; rubber parts easy to aging; thermal expansion of the operation of the reliability . Pump temperature is too high because the pump ambient temperature is too high, the intake air temperature is too high, the intake air cooling device fails, the pump long-term continuous operation into the pressure is too high; water cooling pump insufficient cooling water circulation design is not effective; Water control valve failure and so on. 3, oil spill. Can occur in the shaft seal, the sealing surface of the fuel tank and pump parts, drain plugs, oil standard, hole stuffy head, stator parts and bearing through-hole connections, gas ballast valve (for example, 2X-8) and other parts. Aging by the seal, improper installation, damage failure, the surface is not flat, there are impurities, rough and loose casting caused. If you stop the pump back to the oil, the oil will enter the gas town valve, the gas valve may not leak gas. Homemade rubber mat, be sure to use oil rubber, according to the original design shape, sealing surface is too large when the pressure will leak. Leakage can occur in the water pipe head, water jacket boring cover plane, drain tap, drain valve, etc., water jacket drill wear, casting defects, cracking, may also lead to water leakage. 4, the maximum power exceeded. Continuous long-term work by the inlet pressure is too high, the exhaust pressure is too high, debris into the occurrence occlusion, the pump temperature is too high, the rotary vane with the gap is too small, the voltage is too high, too much pump back into the pump caused by the will Damage to the motor. Should try to avoid long-term continuous operation near the maximum power. If there is sediment on the surface, remove it regularly. 5, the ultimate pressure but the standard. Can be caused by external leakage, internal leakage, oil hole blockage, poor quality or pollution of pump oil, water vapor, etc. until the condensable substance, instrument distortion, pump operation is not normal and so on. 6, more leakage, the exhaust can see the white steam. There are more bubbles at the oil mark, hand feeling exhaust pressure on the exhaust port. Low-level exhaust valve at the surface there are more bubbles. Power will increase. At this time, first check whether the gas ballast valve is closed. As the new pump factory in the pump each port to measure the ultimate pressure, so if the leakage phenomenon, the pump port and piping, valves, containers one by one inspection. Outer shaft seal failure, oil cup oil-free, gas-filled head can also cause leakage. Internal leakage can be the pump movement gap, exhaust valve and other planes, the exhaust valve sealing surface, the shaft seal, pump cover plane, intake pipe, gas valve seals and other causes wear and tear, corrosion, bite will make running clearance plus Big. When the oil hole is blocked, open the oil hole to hear the noise of the pump will be lighter. If the oil seal is good, the exhaust valve may fail if the hand is sucked on the exhaust port. If the pump oil clean, unused long-term storage, open the town valve to purify the water vapor pump. If invalid, check the meter. If the pump oil yellow and white has emulsified, the gas can be fully open the town, adjust the atmosphere to purify the operation, if necessary, the amount of gas into the pump port operation, can speed up the purification process. If other volatile gases or liquids are pumped, please change the oil in time and wash the oil tank if necessary. Some pumps, in the interstital airway will be deposited pump fluid, in order to obtain a good oil change effect, to find ways to drain the pump fluid. The ultimate pressure is measured using a seat compression mercury vacuum gauge. Measured values ​​increase with a full pressure gauge such as a calibrated thermocouple gauge. Note the regulation of the thermocouple gauge to be paired. It is advisable to back up a calibration that is calibrated at the same time for comparison against any suspected contamination regulation. The above is the rotary vane vacuum pump common failure and its maintenance methods, elaborate on the hope that your specific operation and measures to provide some help.

Self-priming pump structure

The main components of the pump are: camshaft, roller body, plunger and plunger sleeve, plunger spring, rotating sleeve and gear ring, the valve and the seat and the pressure pipe and so on. The plunger sleeve and plunger are a pair of major precision couplings in the fuel injection pump. After careful processing and mutual research, their diameter clearance is only 0.001-0.003mm, which can only be changed in pairs and can not be exchanged separately.
The plunger sleeve has two holes to make the inner cavity of the plunger sleeve communicate with the oil channel and the longitudinal groove of the right oil hole, wherein the screw is inserted so that the plunger sleeve can be fixed in the pump body and can not be rotated.
The upper part of the plunger has an annular groove which communicates with the upper end face of the plunger with a longitudinal groove. Helical hypotenuse from the longitudinal groove to adjust the amount of oil supply. The lower part of the plunger has two shoulders and flanges. The plunger shoulder is inserted in the cut-out of the rotating sleeve. The rotating sleeve is freely mounted on the plunger sleeve. The open ring gear is again screwed on the rotating sleeve and meshed with the gear rod.
The gear rack is mounted in the longitudinal bore of the pump body and is connected to the governor lever. When the gear rod moves axially under the action of the joystick and the governor, the rotating sleeve and the plunger on each oil pump also rotate by a certain angle. Lower flange with plunger spring on plunger flange. Spring upper bearing on the pump body. The function of the spring is to move the plunger down. The cam on the camshaft acts on the plunger through the roller body to move it upwards.
Roller body is the driving body between the cam and the plunger, which itself is subject to lateral thrust so that the plunger is only subjected to axial force. The lower part of the roller body is provided with a roller which is arranged on the needle roller bearing, and the upper end of the roller body is screwed into the adjusting screw and the insurance nut.

What are the basic parameters of the pump?

Pumps in the chemical industry, petroleum, paper, flood control, food and other industries increasingly prominent role, so choose a cost-effective pump products is particularly important, on this basis, to understand the pump performance parameters are very Necessary. Today, Xiao Bian here for you to introduce pump parameters which, for your reference when purchasing pump products. What are the basic parameters of the pump? 1, flow Q flow is the amount of liquid delivered by the pump in a unit of time (volume salty mass). Volume flow Q said, the unit is: m3 / s, m3 / h, L / s and so on. Mass flow Qm said, the unit is: t / h, kg / s and so on. The relation between mass flow and volume flow is Qm = ρQ where ρ - density of liquid (kg / m3, t / m3) ρ = 1000 kg / m3 at room temperature. 2, head H head is pumping unit weight of liquid pumping from the pump inlet (pump inlet flange) to the pump outlet (pump outlet flange) the value of energy. Which is the effective energy of a Newtonian liquid through the pump. The unit is N • m / N = m, which is the liquid pumping column pumping liquid height, used to refer to as rice. 3, speed n speed is the number of revolutions per unit time of the pump shaft, symbol n, unit is r / min (rev / min). 4, NPSH NPSH NPSH, also called net positive nozzle, is the main parameter of cavitation performance. Naphthenic margin of domestic use △ h said. 5, power and efficiency Pump power usually refers to the input power, that is, the prime mover to the shaft power, it is also known as shaft power, with P said. Effective power pump, also known as output power, with Pe said. It is the unit of time delivered from the pump liquid in the pump to obtain effective energy. Since the head is the pump's effective weight of liquid output from the pump, the product of the head and mass flow and gravitational acceleration is the effective energy obtained from the pump's output of liquid per unit of time-the pump's effective power.

Sealing compound metering pump selection and routine maintenance

The additives in many sealing compounds are very abrasive and it is more challenging than ever to find dosing pumps that deliver this abrasive compound smoothly. However, there are a number of reliable, non-destructive solutions that use a variety of pump types.

Polyurethane sealing compounds have multiple applications in the electronics industry, such as protecting plastic electrical housings, control units, industrial lighting sources, sensors, etc. from dust, moisture and unwanted interference. To ensure that they work effectively, manufacturers of these systems use a wide range of packings to expand the performance of plastic materials.

However, these additives pose a problem for companies using sealing compounds: how to find a metering pump that can deliver these compounds smoothly.

Figure one

Figure 1. Comparison of three types of pumps. The metered material is a polyhydroxy compound with a density of about 1.6 g / cm3 and a viscosity of about 15,000 mPas.

Electronic components of the sealing process is already quite mature. One-component or two-component sealing compound is passed into the low-pressure mixing metering system for processing and added. Metering pumps are an important part of these systems. Its mission is to pump the sealing compound into the mixing device with a precise flow rate without breaking it. There are various types of pumps that operate continuously and intermittently on the market, but both pumps have advantages and disadvantages. The choice of pump type usually depends on the material's viscosity, abrasiveness and required flow rate (see Table 1).

Figure 2 Figure 2. A long-term comparison of a gear pump and a screw pump. Material: Polyurethane sealing compounds; Filler: no abrasion, 66% addition; Particle size: 16 ?; Viscosity: 20,000 ± 1,000 mPas; Density: 1.64-1.68 g / cm3.

Comparison of metering pumps

The pumps listed below are based on the principle of volumetric metering and allow precise control of the specific discharge of material. The timing pressure measurement, volume and material flow depends on the pressure and viscosity. Pumps used to seal compound metering include:

◆ gear pump (internal gear or external gear)

◆ screw pump

◆ hose pump

◆ piston pump

Gear Pumps - one of the most accurate metering pumps, is ideally suited for the metering of lightly abrasive materials, regardless of whether solid filler is added to the material (from liquid to slurry). Wear-resistant coatings and specially designed gear tooth profiles help to extend pump life. External gear pump pumping flow up to 0.1cm3 / revolution, the measurement pressure up to 100bar. For smaller pumping volumes, internal gear pumps can also be used. This pump is very compact. The internal gear pump is connected to the mixing system and measures up to ± 1% with a metered dose of 20mg (minimum metered dose of 1mg).

External gear pump screw pump and other characteristics

Screw Pump - Ideal for liquids and slurries of various viscosity levels. This type of pump does not easily cause material damage and is not sensitive to packing or abrasive materials. However, screw pumps can not achieve the metering accuracy and flexibility of gear pumps because of their high pressure. Therefore, the screw pump pumping volume can not be less than 1cm3, pressure up to 40bar.

Hose pump - only for low-precision metering, because the hose is very sensitive to pressure. They are an economical solution for the measurement of fillers containing abrasive materials.

Piston pump - suitable for almost any liquid or slurry. Pistons push the material out of the cylinder. After a certain number of measurements, the material will refill the cylinder. Pump models vary depending on the application.

Challenging needs

The demand for plastic chemical properties of electronic components has forced manufacturers to add fillers to epoxy, silicone and urethane sealing compounds to achieve the desired properties of the material. This creates a solid, mixture of different liquid and viscous structures that presents a major challenge for dosing pumps. Special attention must be paid to the following fillers:

◆ chalk

◆ aluminum hydroxide

◆ quartz powder

◆ Desiccant / commercial absorbent (zeolite)

Thixotropic agent

◆ hollow microspheres

These materials can cause damage to the metering pump. However, the pump may also change the characteristics of the material. This is usually a gradual process that is difficult to detect in advance, often as the material passes through the wrong sized components.

When designing a hydraulic circuit, the following factors must be considered:

◆ constant flow rate

◆ ideal for the design of the pipeline flow

◆ lower pressure

◆ minimize the material shear force

These factors are the highest priority when choosing a pump (Table 1).

However, there are other decisive factors, such as:

◆ measurement time

◆ volume flow rate

◆ accuracy

◆ Processing order

◆ measuring temperature

As can be seen from the comparison of three different pump types in Fig. 1, the piston pump has the best dispersibility in the measurement of polyols (density 1.6 g / cm3, viscosity 15,000 mPas) and therefore, from the mechanical properties, The best solution.

Figure 2 shows the long-term comparison of a gear pump and a screw pump. The material delivered was a polyurethane sealing compound where the non-abrasive filler (66%) had a particle size of 16 μm. The compound has a viscosity of 20,000 ± 1,000 mPas and a density of 1.64 to 1.68 g / cm3.

in conclusion

Experience has shown that piston pumps have the longest service life and the highest accuracy, but gear pumps are a good alternative as they are more cost effective than piston and screw pumps and operate continuously. Screw pumps are also suitable for continuous metering of filled materials. Pump in this respect there is no difference between good and bad.

The decisive factor is the system's need. If more than one type of pump is available, personal preferences and logistical factors can have an impact on the decision-making process.

RUBBER Launches New Artist Medium Artist Craftsman Collection

Sirius watch family Artist Medium Artist craftsman series is a bright spot, set engraved car flowers, enamel and hollow several traditional watchmaking craft all in one, now Chronoswiss own watchmaking effort to make a series of new works of artisans have been touched Appearance

Chronoswiss first introduced a solid color enamel dial design, is Chronoswiss own dial workshop produced, another feature is the time-stamp number is not printed on the enamel surface, but inlaid on the dial, so watch dial drilling holes fixed time scale required pole Be careful.

New colors and new patterns combine to create more visual enjoyment Chronoswiss also offers a selection of new models in the Artisan Collection's 34mm automatic movement. Like all other Swatch watches, the sapphire lenses on the case back of the artist's case showcase the beauty of the show - both front and back make it stunning. No matter from which side enjoy Rui Bao artist series, we will see a stunning perfect handmade artwork.

Such small batch production as Ruibao artist series exerts the most skillful tabulation technology. Each Ruibao watch to go through nearly sixty meticulous meticulous processing to the first ticking. These treasures are carefully crafted according to the craftsmanship inherited from a century.

From the artist's collection timer to the start of the Lucerne watchmaking workshop, using only the traditional methods and tools learned by today's watchmakers' great-grandparents. No one table is exactly the same as another.

In the enamel production process, the powdered glass melts on the metal at elevated temperatures, and different colors can be obtained by adding metal oxides. Because the material in the glass makes the real enamel dial more fragile. Soon it was replaced by a very simple and efficient painting process. There is no doubt that watches with enamel today are considered treasures.

For the enamel dial of the rare artist's range of watches, they still have to undergo a harsh test: after seven calcinations and polishing, the dial has to be re-engraved. This is the highest level of handicrafts: Engraving Breguet on such a delicate and delicate enamel, the entire process was completed. Carved colors, bright light, pure enamel dial is to deal with many of the best returns.

Chestnut seed spot disease

Chestnut seed speck disease, also known as chestnut seed kernel dry rot Bo? Chest black blotch? In China's Hebei Province, Shandong Province, the main chestnut production areas occur more common. There is no obvious abnormality in the harvesting period and good fruit, but the storage and transportation period forms small spots on the chestnut seeds, causing deterioration and rot. Therefore, it is an important disease during the storage and sale of the chestnut.

Symptoms: The chestnut kernels produce dark gray, black or dark green rot lesions and gradually turn into dry rot, with empty holes. There are gray-black hyphae in the hollows, and the seeds are easily crushed. The disease department is often infected with bacteria and becomes soft rot that produces offensive odors. The surface of the seed coat is also covered with a black-grey mycelium layer, and seed coats form granular sub-seats. When the chestnut fruit is stored, the seed coat often breaks, exposing the pathogenic sub-seats and showing a sore shape. Sometimes watching from outside the seed coat, there is no obvious change, but the kind of kernel has turned black and decayed. The disease is also harmful to the branches, dry, cause dry rot?

Some research reports classify the symptoms of chestnut seeds and blights into three types: 1 Black spots: The seed coats are generally normal in appearance, and the surface of the seed kernels has irregular dark brown to gray-black lesions on the surface of the seed. Internally, the lesion profile has grayish white to reddish black strips. 2 Brown spot: There are brown necrotic spots with different shades on the surface of the seed kernels, which are deep inside the seed kernels. The cross section of the seed kernels is white, light brown, yellowish-brown, and there are gray to grayish black bars. 3 Rotten type: The kernel becomes brown to black soft or dry rot.
The pre-storage period, that is, the harvest period to the acquisition period, is mostly brown spots, and the later stage is the processing period and the port storage period. The black spot type accounts for the majority, and the two types together account for about 90% of the diseased grains. Symptoms of rot may be later manifestations of necrotic lesions and gradually increase with storage time.
?? Pathogens? Chestnut species pathogenic bacteria are more complex, mostly Plastigomys, Phytophthora, Fusarium, Coccothrax dark conidia and other fungi infestation, in which Ascomycota spore fungus grape seat The main bacteria. The pathogen forms a sub-plant in the diseased branch of the tree. The germ development temperature is 20 to 30°C, and the optimum temperature is 28°C. According to another report from Hebei Agricultural University, there are mainly anthrax pathogens, Alternaria sp., Fusarium solani, Fusarium trifoliatum, Fusarium moniliforme, and Penicillium sp. From the results of isolation, cultivation and inoculation of pathogens, anthrax and Alternaria alternata are the main pathogens of the black-spot type symptoms of the seed. Fusarium and P. palustris are the main pathogens of brown-spot symptoms. The rot type is the later stage of the symptoms of black spots and brown spots.

The temperature of sand storage is about 25°C, which is conducive to the occurrence and development of disease. When the temperature is below 15°C, the disease develops slowly. When the temperature is below 5°C, the development stops. The loss of water on the surface of seed kernels is conducive to the development of diseases, but excessive water loss is the slow expansion of lesions. Saplings and strong trees are lightly affected, and old trees and weak trees suffer from severe disease; airy and clear sunspots in dense chestnut gardens are lightly diseased and poorly ventilated in dense planting gardens; tree trunks have more diseases, insect pests, and mechanical injuries than in chestnut trees; early harvesting occurs. The incidence of chestnuts in the process of storage and transportation is heavy.
Chestnut growth period, young fruit that is carrying bacteria. The chestnuts begin to show symptoms at the end of August and early September, but the incidence is low, averaging 0.5%. The disease rate is about 3% during the collection period, and it will not cause any loss. After harvesting after sand collection, pre-election, to the sale of the acquisition of the station, the disease rate significantly increased, an average of 8%. After processing, it was selected as a product chestnut, and the number of diseased grains increased again, with an average of 10%, reaching the highest peak. After that, the temperature dropped and the incidence no longer increased. From the time of harvesting to the processing period of 15 to 25 days, the high temperature is the critical period for the development of the disease.

Prevention and control methods The key to controlling the disease of chestnut seeds is to reduce operating links, improve storage and transportation methods and conditions, shorten the time of storage and transportation at room temperature, and promptly enter refrigerated or refrigerated ships to take cooling and prevent real losses. Water-centric management measures. Improving tree vigor and raising disease resistance are also important aspects of comprehensive prevention and control.


1. Strengthen cultivation and management, increase tree vigor, increase tree disease resistance, and reduce the number of trees on the tree to send bo?

2, promptly scrape the tree dry rot lesions, cut off the dead branches, reduce the source of pathogen infection.

3, when harvesting, pay attention to reduce chestnut mechanical damage. Rinse the fruit with 7.5% saline, remove the floating diseased fruit, and remove the good fruit by drying and storage.
