Precautions for the use and maintenance of hydraulic motors

Hydraulic motors and hydraulic pumps of the same type are similar in structure and working principle, and from the perspective of energy conversion, the two are reversible. However, due to the different purposes and working conditions of hydraulic motors and pumps, their performance requirements are also different, and there are still many differences between the two.

The daily inspection of hydraulic motors mainly includes checking the operating conditions, working medium, operating sound, and motor temperature rise; The main content of disassembly inspection is whether the components are damaged, interlocked, cracked, and worn.

Precautions during the use of hydraulic motors
① The speed of the hydraulic motor cannot be too low;
② The oil drain port of the hydraulic motor should be separately connected back to the oil tank;

③ When the plunger motor is first used, the housing should be filled with working medium;
④ Necessary measures should be taken in the closed hydraulic motor circuit to ensure reasonable flow matching;
⑤ The viscosity of the working medium should not be too high or too low when starting the hydraulic motor;
⑥ Hydraulic motors that maintain braking status for a long time must use brakes;

⑦ Avoid bearing radial forces on the shaft end of the hydraulic motor;
⑧ The installation orientation of the hydraulic motor drain pipe should be upward;
⑨ The oil outlet of the internal curve hydraulic motor should have a back pressure of 0.5~1MPa;
⑩ The hydraulic motor that starts with a load should be careful not to overload.
