Vacuum pump maintenance tips

【Vacuum pump is a vacuum pump in various ways in a closed space to improve, produce and maintain the vacuum device has been widely used in metallurgy, chemical, food, electronic coating and other industries, plays an important role in the production of the enterprise The role of much market users respected and loved. However, if used for a long time, it will wear out and break down, so we need prompt repair or replacement so as to better ensure its working efficiency and extend its life span. Xiaobian following the vacuum pump for everyone to introduce common faults and maintenance tips. Vacuum pump common fault repair skills Vacuum pump common fault and its maintenance methods, as follows: 1, the shaft bearing wear: vacuum pump transmission parts wear is a common problem, including bearing bit, bearing seat, bearing room, keyway and thread and other parts wear . Maintenance Tips: Contemporary Western countries often use polymer composite repair method, the application of more is the United States and the United States and Ka Wah technology system, with strong adhesion, compressive strength and other properties. This method can be removed to avoid demolition, free machining. Neither repair welding thermal stress, repair thickness is not limited, while the product has the concession, can absorb shock and vibration equipment, to avoid wear and tear, and greatly extend the service life of equipment components, saving enterprises a lot of downtime and create huge The economic value. 2, corrosion: vacuum pump corrosion morphology can be divided into two categories of general corrosion and local corrosion, the former occurred more evenly in the vacuum pump on the entire surface, the latter occurred only in the local, such as pitting, crevice corrosion, intergranular corrosion, stress corrosion . Maintenance Tips: The use of polymer composite materials on the surface of the vacuum pump organic coating anti-corrosion, has a very good chemical resistance and excellent mechanical properties and adhesive properties, compared with the traditional pressure vessel welding repair, with the construction of simple, cost Low, safe performance and good repair effect. 3, shell crack: vacuum pump due to casting, machining defects, internal stress and overload operation and other reasons often lead to cracks or parts of the phenomenon. Maintenance Tips: Conventional repair method is the use of welding, but some parts of the material is cast iron, aluminum, titanium alloy, it is difficult to do the welding process. There are some dangerous situations prone to explosion, but also more difficult to use welding repair methods. Mijia technology is a "cold welding" technology that can avoid thermal stress deformation, and materials with good adhesion and pressure, corrosion and other properties, to maximize the use of various equipment components to meet the requirements of the lowest The cost of investment effectively ensure the production, safety, convenience and reliability. 4, oil spills: This is one of the most common vacuum pump failure, mainly in the vacuum pump oil tank, gaskets, motor bearings shaft seal three positions, the main reason is the vacuum pump is used for too long and cause these parts aging , Seal failure, resulting in oil spills. Solution: Replace aged oil windows, shaft seals, gaskets, and felt pads that have been filled with pump oil. After service is completed, clean the vacuum pump with an EvaPay vacuum pump oil pump and clean the filter screen at the filler neck with solvent to maintain Tank cleaning. 5, pumping the ultimate vacuum of the vacuum pump: First check the vacuum system's tightness, see if there is a slight leak. Secondly, gas ballast should be opened and the pump should be operated for about 30 minutes to pump out compressible steam caused by non-pump oil pollution and to exclude the influence of compressible steam on the ultimate vacuum. Solution: Replace the rotary vane and spring, and clean the rotor and pump chamber; check the exhaust valve to see if its action fails, resulting in poor exhaust, if necessary, replace the exhaust valve. 6, the vacuum pump can not start: The main performance of the vacuum pump can not be started after the operation of power. At this time should first check the circuit part of the vacuum pump, such as the fuse is burned down, the circuit part of the Department has no strength burn out. After excluding the circuit part of the fault, should consider the following two factors: (1) Motor burn out. Mainly for the stator coil burning, causing more causes, such as transient current is too large, the motor bearings worn for a long time, resulting in bearing frictional resistance increases, the motor power increases, causing the temperature rise, burning motor. At this time should first check the motor bearings, and then check the motor coil. Bearing damage to replace the bearing; motor coil burned should repair the motor, re-wound stator coil. Bearing and coil damage is serious, you need to replace the motor. (2) rotary vane jamming. The main performance of the rotary vane and pump cavity surface frictional resistance is too large, resulting in motor can not be driven vane. The reason is that the vane is deformed, the spring in the rotor can not be reset after it is opened, or the combined force of the spring pressure and the centrifugal force of the vane itself is too large, causing the frictional resistance between the vane and the inner surface of the pump cavity to be too large. At this time should be promptly repaired rotary blades and springs, if not repaired, should be replaced. The above is a common vacuum pump failure and its maintenance methods, hoping to use your products and maintenance to provide some help. Industry Internet (Xiamen) Technology Co., Ltd.
