常见故障及使用中的摆线内齿轮电机故障排除

Fault phenomenon	原因分析	Exclusion Method
1. The motor does not turn	①The hydraulic pump is not started or is not turning in the correct direction	① Start the hydraulic pump or correct the pump's rotation direction
	②油箱储油量不足	②Add to the specified oil amount
	③The directional valve is in the neutral position	③Switching Directional Valve
	④The pressure setting value of the overflow valve is too low	④System pressure adjusted to the specified value
	⑤ The motor output torque is insufficient	⑤Replace motor
2. The noise is too loud during operation	①There is air in the hydraulic system	①Identify the cause of air intake and eliminate air in the oil
	②Suction	②Increase fuel supply
	③Failure of internal components such as bearings in the motor	③Replace bearings and other damaged parts
3.内、外泄漏过大	①Sealing component damage causes internal and external leakage	①Replace sealing components
	②Motor parts have air holes, sand holes, cracks, etc.	②Replace parts
	③Loose bolts	③Tighten the bolts
4. Abnormal fever	①Hydraulic oil temperature is too high	①Increase cooling capacity
	②Motor efficiency decreases	②Replace consumable parts
	③Abnormal wear	③Replace motor
