Main Functions
1. Converts hydraulic pressure energy into rotary mechanical energy to provide low‑speed high‑torque power
2. Used for heavy‑duty and low‑speed driving; can directly drive loads without reduction mechanism
3. Bi‑directional rotation with sensitive forward/reverse switching and stable braking performance
Common Faults & Phenomena
1. Insufficient output power and torque: Internal wear, scratched valve plate, excessive internal leakage
2. Unstable speed and vibration: Impurities in hydraulic oil, rotor wear, unstable flow rate
3. Oil leakage: Aging shaft seal, damaged end‑cover seal, casting defects on housing
4. Abnormal noise: Worn bearings, abnormal meshing between rotor and stator
Installation & Operation Requirements
1. Hydraulic Oil: 46# anti‑wear hydraulic oil with cleanliness within NAS 8 grade
2. Install filter at oil inlet to prevent impurities from entering the motor
3. Avoid over‑pressure and over‑speed operation; replace hydraulic oil and filter regularly
4. Prevent radial impact load on output shaft; mainly bear axial torque
