1. when the moment of inertia of the driven parts is large, if braking or reversing or shunting is required in a short time, a safety valve buffer shall be installed in the oil return circuit to prevent damage to the hydraulic motor due to excessive hydraulic impact.
2. when using quantitative motor, if it is necessary to start and stop smoothly, necessary pressure control or flow control methods shall be adopted in the circuit design.
3. when the hydraulic motor is used as the power component of the lifting tool or traveling device, the speed limit valve must be set to prevent the heavy objects from falling rapidly or the vehicle from speeding down the slope, resulting in serious accidents.
4. because the hydraulic motor always leaks, it will still slide slowly when the inlet and outlet of the hydraulic motor are closed for braking. When long-term braking is required, another brake shall be installed to prevent rotation.
5. when full load starting is required, pay attention to the starting torque value of the hydraulic motor, because the starting torque of the hydraulic motor is less than the rated torque. If it is ignored, the working mechanism will not work.
6. since the back pressure (outlet pressure) of the hydraulic motor is higher than the atmospheric pressure, the discharge pipe of the motor shall be returned to the oil tank separately and cannot be connected with the return pipe of the hydraulic motor.
