H - 150 sliding pneumatic valve type vacuum pump failure phenomenon and elimination method of 6

H - Slide pneumatic valve vacuum pump malfunctions and troubleshooting: vacuum is not high: ( ） 。 The leakage of the pump. （ ） 。 Of oil absorption, the hole in a fog: cleaning oil cooler, check the oil pipe, pump. （ ） 。 A gas ballast pump oil pollution: pneumatic valve - operation Hours or longer, or oil change. （ ） 。 Fuel shortages, the oil level is too low, oil. （ ） 。 The oil temperature is too high, increase the amount of water, reduce the environment temperature and suction temperature, eliminate the obstruction, bad lubrication. （ ） 。 Exhaust pneumatic valve damage: used in pneumatic valves. （ ） 。 Exhaust air valve spring damage: a new. （ ） 。 Pump wear parts, different sound, power supply abnormality: rotation of maintenance spare parts management pulled down. Two oil: check the seal, seal, adjustment or replacement. Noise: abnormal noise: check whether the foreign body into the pump chamber, bearing, pumps, transmission parts damaged. Demolition, repair, update. Injection: there are a lot of smoke oil: check the oil level is too high, such as too high, release; Gear oil components, fuel and other defense injection molded parts is complete. Vibration: big: whether mat foundation inspection, fastening, infrastructure is enough. It with a bite, adhere to the early signs of adjustment. Kind of heat pump bearing temperature anomaly: a small pine bark, and check the oil is smooth, does not have enough water. Heating oil tank, the exhaust overheating: reduce the inlet pressure, improve the cooling water. Stuck occlusion: will investigate whether foreign body, whether it's a good part of proper lubrication, fuel oil, engine oil, the oil pump. , the motor current is too large or fuse: check the electric current is too large, the fuse capacity, the cause of the new adjustment.
