1.四川升降平台液压泵是都能够输出液压油,若无液压油输出则可能是沈阳升降平台液压泵的转向不对,应调整电机相位,若有液压油输出,则应检查各回油管,可能是调定压力低。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.

2.四川升降平台压力油从高压腔向低压腔泄露,可能是由于安全阀没关严,也可能是因为活塞杆或活塞处的密封圈损坏。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.

3.四川升降平台液压泵吸油不足,滤油器堵塞,应清洗或更换滤油器。Sichuan lifting platform hydraulic pump, oil filter plugging, oil filter should be cleaned or replaced.

4.液压泵发热,油温过高 液压泵损坏,应更换新的四川升降平台液压泵,油液粘度过高,应选用合适的粘度,冷却不足应改进冷却系统。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.液压泵转速过低,皮带打滑,联轴节和原动机出现故障应排除。The hydraulic pump speed is too low, the belt slipping, coupling and motive of failure should be excluded.

6.若四川升降平台液压泵输出流量随压力升高而显著减小,且压力达不到规定值,则是因泵损坏之后间隙增大所致,应进行修配或更换。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.若四川升降平台整个系统能建立正常压力,而某些管路或液压缸、马达中无压力,可能是管里小孔,节流阀,换向阀等部位堵塞,应逐个检查压力和有无油液通过找出原因加以排除。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.
