Vacuum booster pump is mainly used for drawing light vacuum booster brake system can also be used for other transport vehicles and construction machinery. The use of vacuum assisted braking system can improve brake reliability and reduce driver fatigue, help reduce the incidence of traffic accidents and improve vehicle safety. 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. 1 vacuum booster pump works Vacuum booster pump mainly by the pump body, rotor, slider, pump cover, gears, seals and other components. When the pump is working, the eccentric rotor with four sliders rotates in the counterclockwise direction, the sliders slide on the inner wall of the pump body under the action of centrifugal force of itself, the suction working chamber expands constantly, Tube open the check valve (pump built-in check valve, the system from the packing effect) into the suction studio. When the slider to a certain position, inhalation is completed. At this point, the inhaled gas is isolated, the rotor continues to rotate, the isolated gas is gradually compressed - the pressure rise. When the studio goes to communicate with the vent, the gas is vented from the vent. During pump operation, the slider always divides the pump chamber into four working chambers, with one revolution per rotor and four intake and exhaust processes. 2 Use and Maintenance Vacuum booster pump is a high precision and sensitive working vacuum pump. The following rules must be strictly observed: (1) The vacuum booster pump uses oil to lubricate the friction surface to seal the gaps (rotor, slider, Pump body, the gap formed by the pump cover), so you must choose the right lubricant and the appropriate lubrication. (2) use, should always check the operation and lubrication is normal, with or without abnormal noise, in order to promptly find (model forum) and troubleshooting. (3) during use, should always check whether the leakage pump. (4) If you do not use the vacuum booster pump for a long time, do not immediately work full load when reused. 3 common faults and troubleshooting (1) the pump to extract the maximum vacuum is low, the extraction time is extended Fault causes: inadequate viscosity of lubricating oil; suction pipe leakage: parts wear; gap increased leakage. Fault diagnosis and troubleshooting: Check the viscosity of lubricating oil, if not qualified, replace the appropriate viscosity of the oil; check whether the pipeline leaks, if leaks, you need to replace the leaky parts: Check the parts for wear and tear, if worn , Need to be repaired or replaced with new parts; check the lubricating oil pressure, and meet the requirements. (2) Insufficient pump pressure, gas leakage Cause: Gas seal leak diagnosis and troubleshooting: Check the seal is worn and inelastic, if worn, need to be replaced with a new seal. (3) Air leakage at each interface Cause: The connector is loose or the seal is damaged. Fault diagnosis and troubleshooting: Check whether the connector is loose or not. If it is loose, seal the connector and tighten the connector. If the seal is damaged, replace the new one. 4 Disassembly Pump Precautions Vacuum pump components within the high precision and assembly accuracy, in general, users do not disassemble. Should be sent to the manufacturer or repair center for inspection and repair, if the need to disassemble, you should pay attention to the following: (1) vacuum booster pump rotor and gear are interference fit, can not be removed. (2) The parts are not allowed bump and scratches, the parts clean with kerosene, stored in a clean box. (3) should pay attention to the sliding block slider arc outward, may not be installed. (4) parts must be clean assembly. (5) After the pump is assembled, the rotor should rotate flexible.
