Import pneumatic diaphragm pump installation process

Pneumatic diaphragm pump If you ignore some of the details of the installation may result in poor pump performance and affect the life of the pump, the import of pneumatic diaphragm pump is a diaphragm pump, the following Xiaobian detail imported pneumatic diaphragm Pump specific installation process. 1, pneumatic diaphragm pump installation and start: The diaphragm pump placed as close to the product where possible, the suction pipe line shortest, reduce the number of configuration components, do not reduce the pipe size. To extend the life of the diaphragm, keep the pump as close as possible to the fluid being pumped and require a slow pressure adjustment mechanism to extend the diaphragm life at inlet pressures in excess of 10 feet (3 meters). If hard piping is installed, use a short hose between the pump and the piping. Hoses can slow pipe vibrations and distortions, and a surge tank is recommended to further reduce the pulses in the fluid. 2, to the diaphragm pump gas supply: Metal diaphragm pump supply pressure shall not exceed 125psi (8.6bar), plastic pump supply pressure shall not exceed 100psi (6.9bar). Connect the air inlet of the pump to the air supply with enough capacity and pressure to meet the design requirements. If the air supply line is a hard pipe, connect a short hose between the pump and the pipe to reduce distortion. In addition to the air inlet cap, the air intake pipe, the pressure regulator filter weight must also be supported by some means. Failure to support the pipe may damage the pump. Pressure regulators must be installed to ensure that the supply pressure does not exceed the specified range. 3, the diaphragm pump before the operation check: diaphragm pump work before the prosecution of all fixed objects to prevent relaxation, tighten the loose place to avoid leakage, with the card attached to the card described in the method of fixing. 4, diaphragm pump intake and start: start, the air valve open about 1/2 to 3/4 laps. After the pump is started, open the air valve to increase air flow to achieve the required flow rate. 5, pneumatic diaphragm pump exhaust: If the diaphragm is broken, the extracted liquid or gas will enter the pump air port, was discharged into the atmosphere, when the extraction of dangerous or toxic substances, the need to pipe to the appropriate place for safe handling . If the pump is submerged in the liquid, the gas is drained from the liquid level and the exhaust pipe can not be smaller than 1 "(2.45cm). Reducing the size of the exhaust pipe will limit the gas flow rate and reduce the pump usage. When the material level is high In the pump, the discharge outlet should be at a higher place to prevent siphon phenomenon.Under a certain temperature and humidity, the discharge of gas may freeze up, the use of gas drying can eliminate most of these problems. 6, pneumatic diaphragm Pump after use: If used to transport easily curable materials, to prevent damage to the pump, thoroughly clean the pump after each use (after use, the product left in the pump has dried or stuck to the pump, so In the next start-up will cause diaphragm and valve problems). In the freezing temperature, in any case must be drained pump after the above is the pneumatic diaphragm pump installation process, I believe you have installed on the pneumatic diaphragm pump A deeper understanding, but also hope you can better correct installation of pneumatic diaphragm pump.

PC plastic,full name Polycarbonate.

PC plastic is a kind of excellent comprehensive performance engineering plastics.It has excellent physical, mechanical, electrical, and thermal properties,so it's known as the "king of the transparent plastic'

Classification:

Anti - static PC SHEET, conductive PC SHEET,fireproof PC SHEET,PC fiber - resistant, PC GF SHEET, PC+ABS SHEET,anti-ultraviolet ray resistance PC, food grade PC, anti - chemical PC.

Advantages:

1,Light weight

2,Impact resistance

3,Excellent physical, mechanical, electrical and thermal properties

4,Ultraviolet resistance

Disadvantages:

Polycarbonate is not resistant to ultraviolet light, no resistance to alkali, resistance to hydrolysis stability is not high, is the main performance defect is sensitive to the gap, resistance to organic chemistry, scratch resistance is poorer, long-term exposure to ultraviolet light yellow, are vulnerable to the erosion of some organic solvents.

Applications:

1. Dust-free room spacer

2. Equipment shield and test fixtures;

3. Commercial Building Lighting;

4. Soundproof walls;

5. Greenhouse;

6. Components for medical and pharmaceutical devices;

7. Face shields;

8. Skylights, etc

Modified use:

The purpose of the modified PC Plastic is to toughen, improve the processing performance, reduce the residual deformation, and increase the flame retardancy, etc.

PC/ABS can improve bending modulus, heat resistance and plating performance.

PC/PET and PBT can improve drug resistance and solvent resistance.

PC/PMMA added plexiglass to enhance the appearance of pearlescent color.

PC/PA and HIPS can improve impact toughness and surface finish.

PC/HDPE can improve water resistance, aging resistance, weather resistance and LDPE.

The PC Plastic USES fiberglass or carbon fiber to enhance modification and improve mechanical strength.

The flame retardant grade PC Plastic can be made with bromine flame retardant and antimony trioxide.

Other and polysulfone, aromatic polycarbonate, polyvinyl formaldehyde, polypropylene, polystyrene can be modified to achieve the balance between economy and performance.


Combustion characteristics:

Combustion condition: easy, softening foaming

Flame status: small amount of black smoke

After the fire: out of the fire

Bouquet: no special taste

Specification: the thickness of PC Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of 10-180mm is 600*1200 mm. PC Plastic sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.and The diameter of the PC Plastic rod can be produced from 2mm to 250mm, the length is 1 meter, and it can be ordered to be more than 3 meters in length.

Color: Black and clear, can also be made another color, and the color order is 500KG.


Modified varieties:PC Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.

Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
