• Final Drives motor

What are the precautions for using hydraulic motors?

1 Ensure that the output shaft of the hydraulic motor is concentric with the machine or a flexible connection. 2 Before starting the hydraulic oil motor, the housing should be filled with oil. The housing must always be filled with oil to provide internal lubrication, otherwise the oil motor will be pulled and cast into a big mistake! 3 Leakage connection: The hydraulic motor housing leakage pipe must be full diameter.

2 Before starting the hydraulic oil motor, the housing should be filled with oil. The housing must always be filled with oil to provide internal lubrication, otherwise the oil motor will be pulled and cast into a big mistake!

3 Leakage connection: The final drives housing leakage pipe must be full-bore, free from throttling, and connected directly from the leakage port to the fuel tank, so that the casing is kept full of oil, the piping of the leakage pipe must avoid siphoning, and the drain pipe should make it It ends below the tank level and other lines must not be connected to the drain. The drain pipe of the hydraulic motor should be connected to the fuel tank separately and should not be connected to the circuit port.

4 The external draining pipe of the hydraulic machine should ensure that the oil motor casing is filled with oil to prevent the oil in the casing from flowing back to the fuel tank when the vehicle is stopped. For example, the leakage pipe interface is upward, so that the oil discharge port is higher than the casing.

5 The general drain port is not connected to the back pressure. If the hydraulic press needs to be connected to the back pressure, its value should not exceed 0.16-0.20MPa, otherwise the oil pressure will break through the low pressure seal, such as shaft seal.

6 should ensure that the low-speed large torque motor has sufficient back pressure back pressure, especially the internal curve oil motor should pay attention to, usually its back oil pressure should be 0.3-1MPa, the speed is high, it will be stressed by the oil pressure, otherwise Will cause the roller to get off the stator rail surface and cause impact, vibration, noise, and serious damage. https://www.spfinaldrives.com/
