I.Vacuum pump accessories as follows.
1. Oil mist filter ( alias: oil mist separator, exhaust filter, exhaust filter element )
Vacuum pump oil mist separator under the action of the driving force, located on one side of the oil and gas mixture through the vacuum pump oil mist separator filter paper and cotton. Then the oil is trapped, realizing the operational process of separation of gas and vacuum oil. The filtered vacuum pump oil is recycled with the oil return pipe, and the discharge is oil-free exhaust gas, which achieves the effect of no pollution and cleanliness.
2.Air filter (alias: air filter element)
The sliding space of the vacuum pump is very small, foreign media containing particles, dirt, will damage the sliding surface, the sliding surface of the pump is attached or blocked, resulting in the pump can not work properly. In order to prevent foreign matter from being sucked into the pump, it is necessary to use a filter to block its entry into the pump. In case there are air impurities not filtered, cleared out, and into the pump, which may lead to oil pipe blockage, lubricating oil becomes mixed. So it is necessary to choose the principle genuine products. Later maintenance and repair: the use of vacuum pump air filter should be cleaned regularly to prevent the impurities that stay in the filter from being sucked into the pump causing the pump to jam and other phenomena.
3.Oil filter (alias: oil compartment)
Oil grid, also called oil filter. Vacuum pump oil filter is an oil filtration device configured by many imported vacuum pump brands, set in the pump return line. The main purpose is to capture the contaminants occurring or invading in the system in the return tank. Therefore it is also an important filtering device to control the pollution concentration of the system.
II.Common failures of vacuum pump spare parts
1. Abrasion
Abrasion is a common failure mode of vacuum pump spare parts, one is under the condition of lubrication, the frictional abrasion of the contact surface between spare parts, often occurs in the gear, cylinder, vane, rotor slide bearing, rolling bearing. This type of abrasion is slow, abrasion loss effect is mainly related to lubrication, sealing conditions. The other is in the non-lubricated conditions, the spare parts of mutual friction or material friction on the surface of the spare parts caused by the abrasion, which is particularly prominent in the vacuum pump. Such as coupling, 2X pump pulley, twin screws of screw vacuum pump, etc.. This kind of wear speed is much faster than the former, mainly related to the performance of metal materials and the nature of materials. For oil vacuum pump, the abrasion in lubrication is especially prominent, mostly due to the deterioration of vacuum pump oil and foreign impurities leading to poor lubrication.
2.Fatigue breakage
Fatigue is a failure mechanism and the generation of cracks is a failure mode. They often cause the final breakage of the spare parts. This fatigue breakage failure process is generally found in gear parts that are subjected to alternating loads. It is common in parts such as coupling bolts, foot bolts, springs, etc., and also occurs in important spare parts such as gear drive shafts. Fatigue breakage involves a number of factors, which require specific analysis of the failed spare parts to identify the causes and take countermeasures.
3.Deformation
Deformation is also a common failure mode of vacuum pump spare parts. Since the pump will generate a certain high temperature when running at high speed. Such as shells, plates, etc. are often in a heated state, the most likely to occur deformation. Gradually generated plastic deformation can not restore the original geometry and shape of the spare parts, in serious cases will cause equipment failure. Such as seal rings, oil seals, etc.
4.Corrosion
Corrosion is a mode of failure of vacuum pump spare parts. It is commonly found in vacuum pumps operating under more complex processes such as PCB, chemical and other working conditions.
These spare parts are wearing parts, such as the above situation need to replace the spare parts. When the vacuum pump failure, we have to check the processing, to determine the failure of its spare parts, for the above problems to make the appropriate measures to solve. In order to have a longer service life of the equipment, we need to maintain its regular maintenance and repair, to reduce the frequency of failure.
Magnetron sputtering coating production line adopts PLC combined with panel, designed with complete function menu to realize the whole process monitoring for the whole production line components running status, and process parameter setting, operation protection and alarm function; the whole electrical control system is safe, reliable and stable. With heating system, the vacuum partition of vacuum pumping system adopts independent door valve, and the vacuum partition is very reliable. The vacuum chamber adopts building block structure, and the coating chamber can be increased according to the functional demand. The production line pumping system adopts molecular pump as the main pump for pumping, the vacuum chamber pumping speed is stable, fast and low cost.
Mainly used for flat glass, acrylic, PET and other products on the coating, can be coated with a variety of metal film, dielectric film, dielectric metal composite film, EMI shielding film, non-conductive film and other film layers.
