Rexroth hydraulic pumps and hydraulic motors are important components of hydraulic systems. Their fault analysis and solutions are as follows:
Rexroth hydraulic pump fault analysis and solutions
- The pump does not deliver oil, the pump output is insufficient, the pump pressure is insufficient or the pressure cannot be increased: it may be caused by internal wear of the pump, improper oil viscosity, leakage or blockage of the suction pipeline, т.б. The solution includes checking the wear of the internal parts of the pump, adjusting the oil viscosity, and checking the sealing and smoothness of the suction pipeline.
- Abnormal pump pressure or flow: it may be due to damage to the internal parts of the pump or failure of the adjustment system. It is necessary to check the internal parts and adjustment system of the pump and replace or adjust them if necessary.
- The pump is noisy and the pump is abnormally hot: it may be due to wear of the internal parts of the pump or poor lubrication. The solution includes checking the wear of the internal parts of the pump and the lubrication system, and making necessary replacements and lubrication.
- The Rexroth hydraulic pump shaft seal is leaking oil: it may be due to wear or damage of the shaft seal. The solution is to replace the shaft seal.
- System oil temperature is too high: it may be due to the small system pipeline, high pressure, hydraulic oil cannot be discharged in time or the cooling system does not meet the requirements. Solutions include increasing the system pipeline, reducing the pump displacement, and adjusting the cooling system to increase the cooling effect.
Rexroth hydraulic motor fault analysis and solution - Abnormal speed and torque (too small or too large): it may be due to wear of internal parts of the hydraulic motor or failure of the adjustment system. The solution includes checking the wear of internal parts and the adjustment system, and making necessary replacements and adjustments.
- Large leakage: it may be due to wear or damage of seals. The solution is to replace worn or damaged seals.
