At present, the rapid development of domestic light vehicles, which undoubtedly for the vacuum booster pump provides a vast market. Therefore, in the promotion and use of the process, we must understand and master its performance, principles. The only way to effectively ensure the pump braking performance, extend the service life, play a safety role. Vacuum Booster Pump Common Malfunctions and Maintenance Methods Vacuum Booster Pump Common Malfunctions and Maintenance Methods Vacuum booster pump is a kind of high precision and sensitive working pump. When using, the following rules must be strictly observed: 1. Vacuum booster pump uses oil to lubricate friction Surface, seal all gaps (rotor, slider, pump body, pump cover the gap formed), so must choose the appropriate lubricant and appropriate lubrication. 2, the use should always check the operation and lubrication is normal, with or without abnormal noise, so that timely detection and troubleshooting. 3, the application should always check whether the pump leakage phenomenon. 4, if a longer time do not use the vacuum booster pump, re-use, not immediately full capacity. Third, the common failure and troubleshooting 1, the pump to extract the maximum vacuum is low, the pump extraction time extended; Failure reasons: Run, lubricating oil is not sufficient; suction pipe leakage; parts wear; gap increased leakage. Troubleshooting: Check the viscosity of lubricating oil, if not qualified, the replacement of the appropriate viscosity of the oil; Check whether the pipeline leaks, if the leak, you need to replace the leak; Check the parts for wear and tear, if worn Those who need grinding or replacement of new parts; check the pressure of lubricating oil, and meet the requirements. 2, the pump does not maintain pressure, leakage; Failure reasons: seal leakage diagnosis and troubleshooting: Check the seal is worn and inelastic, if worn, need to be replaced with a new seal. 3, the interface at the leak; cause of the malfunction: loose joints or seal damage. Fault diagnosis and troubleshooting: Check whether the loose joints, if loose, need to be sealed sealant fastening joints; if the seal is damaged, the need to replace the new pieces. 4. Disassembly pump precautions Each component in the vacuum booster pump has high machining accuracy and assembly accuracy, in general, users do not disassemble, there are questions should be sent to the manufacturer or repair center for inspection and repair, if Must be disassembled, you should pay attention to the following: a, vacuum booster pump rotor and gear are interference fit, can not be removed. b, the parts do not allow bumps and scratches, the parts clean with kerosene, stored in a clean box. c, install the slider should pay attention to the slider arc outward, may not be installed. d, assembly parts must be cleaned. e, pump assembly, the rotor should be flexible rotation. 5, Storage vacuum booster pump should be stored in a dry, non-corrosive gas warehouse, not in the high temperature and -20 ℃ below the low-temperature environment for long-term storage, so as to avoid rubber seal aging, and often check the corrosion, if necessary Replace pump anti-corrosion oil.

Stellite Valve Ball And Seat are very important parts of underground oil-well pump , they always show up together and cooperate very good , no better material can replace stellite now .
The valve balls are made of Stellite 20 and Valve Seat are made of stellite 3 . They are a good team to resist the wear and corrosion issue in oil and gas pimping process .
