6 precautions when using a travel motor
When the travel motor is in use, we often encounter different problems, but because of the special working conditions of the travel motor, there are six special points to be aware of when using it.
1. When the full load is required to start, it should be noted that the running motor starts to shorten the value. Because the starting torque of the traveling motor is shorter than the rated torque, if it is ignored, the working mechanism will not operate.
Second, since the back pressure of the final drive motor is higher than the atmospheric pressure, the drain pipe of the motor must be separately led back to the fuel tank and cannot be connected with the return line of the traveling motor.
Third, because there is always leakage in the travel motor, the intake and exit of the travel motor are closed for braking, and it will still have a slow slip. When it is necessary to brake for a long time, a brake to prevent rotation should be separately provided.
4. When the driven part has large inertia (large moment of inertia or high speed), if it is required to reach the brake or the case or the shuttle in a short time, a safety valve (buffer valve) should be installed in the return line to prevent sharpness. The hydraulic shock caused damage accidents.
5. When the final drives is used as a power component for lifting or walking devices, a speed limit valve must be installed to prevent the heavy objects from falling quickly or overspeeding when the vehicle and other traveling mechanisms are going downhill, resulting in serious accidents.
6. When using a fixed-quantity motor, if it is desired to start and stop smoothly, the necessary pressure control or flow control method should be adopted in the circuit design. https://www.spfinaldrives.com/
