1.四川升降平臺液壓泵是都能夠輸出液壓油,若無液壓油輸出則可能是沈陽升降平臺液壓泵的轉向不對，應調整電機相位，若有液壓油輸出，則應檢查各回油管，可能是調定壓力低。Sichuan lifting platform hydraulic pump can output hydraulic oil, without hydraulic oil output may turn right Shenyang lifting platform hydraulic pump, should adjust the motor phase, if the hydraulic oil output, it should check the return pipe, may be adjusted in low pressure.

2.四川升降平臺壓力油從高壓腔向低壓腔泄露，可能是由于安全閥沒關嚴，也可能是因為活塞桿或活塞處的密封圈損壞。Sichuan lifting platform pressure oil from the high pressure chamber to the low pressure chamber leak, may be due to the safety valve is not closed, it may be because the piston rod or piston seal ring damage.

3.四川升降平臺液壓泵吸油不足，濾油器堵塞，應清洗或更換濾油器。Sichuan lifting platform hydraulic pump, oil filter plugging, oil filter should be cleaned or replaced.

4.液壓泵發熱，油溫過高 液壓泵損壞，應更換新的四川升降平臺液壓泵，油液粘度過高，應選用合適的粘度，冷卻不足應改進冷卻系統。High temperature heat pump, hydraulic pump damage, should be replaced with new Sichuan lifting platform hydraulic pump, oil viscosity is too high, we should select appropriate viscosity, insufficient cooling cooling system should be improved.

5.液壓泵轉速過低，皮帶打滑，聯軸節和原動機出現故障應排除。The hydraulic pump speed is too low, the belt slipping, coupling and motive of failure should be excluded.

6.若四川升降平臺液壓泵輸出流量隨壓力升高而顯著減小，且壓力達不到規定值，則是因泵損壞之后間隙增大所致，應進行修配或更換。If Sichuan lifting platform hydraulic pump output flow with high pressure decreased significantly, and the pressure is not up to the specified value, is due to pump damage after the gap increases due to repair or replacement should be carried out.

7.若四川升降平臺整個系統能建立正常壓力，而某些管路或液壓缸、馬達中無壓力，可能是管里小孔，節流閥，換向閥等部位堵塞，應逐個檢查壓力和有無油液通過找出原因加以排除。If Sichuan lifting platform of the whole system can establish normal pressure without pressure or some pipeline hydraulic cylinder, motor, may be tube holes, throttle valve, reversing valve and other parts should be checked one by one block, and there is no pressure oil through to find out the reason to be excluded.
