H-150 slide valve vacuum pump maintenance and care
1. The pump and its environment should be kept clean from time to time. 2. Should always pay attention to the oil level, see 5.2, low should be refueling, high should be released. Open the town of oil emulsion purification or oil change. 3. The new pump is recommended after 150 hours of work once, pumping dry and clean air, it is recommended to change in 500-1000 hours. If necessary, shorten the oil change cycle. 4 pay attention to the oil temperature and cooling water outlet temperature testing, in order to take timely measures to prevent occlusion failure occurs. 5. When the ambient temperature is low, pump water should be shined in time to stop the water pump to prevent freeze-thaw pump body. 6. Pump oil. See 3. If the vacuum performance requirements are lower, but also frequent oil changes, allowing the use of mechanical oil HJ-50. 7 Regularly clean the oil filter copper network, to maintain smooth, clean, otherwise, lack of fuel will reduce the performance of the pump. 8 pump stop without, to open the pump every 7-10 days about 1 hour, so as not to pump corrosion. 9 removal steps: (1), drain, drain the oil. (2), demolition shields. (3), demolition pump triangular pulley, balance wheel. (4), diesel pipe and pump. (5), bearing cover and sealing device. (6), A, B cap (with bearings). (7), pull out the slide valve and rail assembly. (8), pull out the eccentric wheel, flat key and shaft. (9), To repair the exhaust valve, to remove the fuel tank, oil cover assembly, exhaust sleeve, connecting seat. Remove the connector when the first loose nut, into the set screw, exhaust valve assembly can be removed. 10. The assembly procedure is the opposite of the above. 11. Disassembly Notes: Prevent hammering bang, hammer can not be directly beat the processing surface, the pre-installed cleaning must be done to prevent impurities into the friction surface to be coated with clean oil, pump cover sealing surface must be clean, oil-free, Prevent oil leakage, leaks. 12. If the silicone rubber seal, should be proportionally mix the silicone rubber, catalyst and catalyst, sealing surface should be clean and oil-free.
