Excluded methods expeller common fault

1 cylinder and piston leak repair, if the leather bowl bowl is arranged on the genus to fault caused by, should be the right way to install the leather bowl. If the cup cracked and damaged, should be replaced with new cup.

2 valve repair failure, if there is oil in the dirt does not cause steel ball valve seal, valve should be cleaned, remove dirt, so that ball valve closed. If the spring loses elasticity can not withstand high pressure, you should replace the new spring. If the adjustment screw loose, cause jump valve not to pressure, should be re adjusting screw, the pressure to achieve the required pressure valve just jump. If it belongs to the overpressure operation often, led to the valve ball bumps, should be re grinding valve, replace the new ball and pay attention to the operationaccording to the operating rules.

3 pump maintenance is not absorbing, if the oil strainer clogging dirt, should wash the oil strainer. If the oil used for a long time, because of sediment attached to the oil inlet valve and the valve is not closed, should be replaced with new oil or release the old oil filter and clean the oil valve. If it is insufficient fuel tank, add enough oil to the tank can, if not into the vacuum pump, can pull out a small piston, then into the oil pressure.

4 oil pressure, lack of maintenance, if there is dirt or sealed valve bad, to be ground after removable and washable, so close together. If the oil inlet valve plug and valve seat contact bad press, can also be ground after washable, so close together. If the press and out of the oil valve plug or poor contact with the fastening seatcaused by oil spills, oil press can grind upper oil plug valve and valve seat, to seal or tighten the drain plug. If a small piston and the wear of the pump clearance is too large, should be replaced with new pumps.
