Measures to prevent oil leakage:

1. Oil leakage is caused by extremely high oil pressure inside the motor housing, so all measures to prevent leakage should aim to relieve pressure. There are actually the following methods.

2. Reasonable layout of drainage oil pipes: Many hydraulic professionals do not attach great importance to the configuration of drainage oil pipes, thinking that as long as they directly return to the oil tank, the pipe diameter size is not important. From the calculation formula of frictional resistance along the way, it can be seen that the frictional resistance is inversely proportional to the 5th power of the pipe diameter. Under the same other standards, as long as the diameter of the drainage oil pipe is changed to 10, the frictional resistance along the way is Pf=0.15MPa. In this situation, the regulations for oil discharge pressure can be fully met.

3. In addition, attention should also be paid to the influence of pipe length, as there is a linear correlation between pipe length and frictional resistance along the way. Under the same standard, if the pipe length is doubled, the frictional resistance will also double. Therefore, special attention should be paid when the oil discharge pipeline is long.

4. Reasonably determine the flow rate of cleaning oil, because a small flow rate of cleaning oil cannot achieve cooling effect, but a large flow rate of cleaning oil will increase the frictional resistance of oil leakage.

5. The correct cleaning flow rate can be determined by referring to the manufacturer's technical information or by calculating based on thermal balance standards.
