Marine hydraulic motors are the heart of ship deck machinery. As for ships, deck machinery is equivalent to arms and people. Therefore, deck machinery is very important to a ship, so the importance of marine hydraulic motors to ships is self-evident.

1. Under the premise that the main circuit safety valve, overload valve and other accessories are intact, seal the oil inlet pipe and the motor interface (no oil leakage), and measure the maximum pressure of the oil supply circuit when the motor is forward or reverse; connect Pass the motor pipeline to measure the pressure when there is a load; finally, compare the measured value with its technical requirements to determine the fault location.
2. Insufficient flow or low pressure of the hydraulic pump will reduce the output power of the motor and the torque and speed at the same time. Therefore, the flow measurement should be performed simultaneously with the measurement pressure.
3. Check whether the clearance between the distribution shaft and the rotor hole Outdoor Power Equipmentsis within the allowable range, and check whether the rotation center line of the distribution shaft and the cylinder bore are consistent. If it exceeds the allowable value, reassemble it. If the matching clearance between the distribution shaft and the rotor hole exceeds 0.6mm, or the distribution hole in the rotor has a groove along the circumferential direction; the clearance between the plunger and the rotor exceeds 0.05mm, and the clearance between the roller square shaft and the sliding groove exceeds 0.05mm, both It will make the low-speed high-torque inner curve motor weak. If the two walking motors are not synchronized, the track will be deflected.
