How Do Hydraulic Motors Prevent Oil Leakage?

Measures to prevent oil spills:

1. The oil leakage is caused by the ultra-high oil pressure in the hydraulic motor housing, so all measures to prevent leakage should be aimed at reducing pressure, specifically the following methods.

2. Reasonable configuration of the drain pipe: many hydraulic technicians do not pay much attention to the configuration of the drain pipe, that is, as long as it is directly back to the tank, the diameter of the pipe does not matter, from the calculation of the resistance formula, the resistance is inversely proportional to the 5th square of the diameter of the pipe, under the same other conditions, as long as the diameter of the drain pipe is changed to 10, then the resistance along the pipe :Pf=0.15MPa. In this case, the drainage pressure requirements can be fully met.

3. In addition, we should also pay attention to the influence of pipe length, because the pipe length and the resistance along the linear relationship, under the same conditions, the pipe length doubled, the resistance also doubled, so in the long drainage pipe should be paid special attention.

4. Reasonably determine the flushing oil flow rate, because the flushing oil flow rate is too small to achieve the cooling effect, but when the flushing is too large, it will increase the drainage resistance.

5. The correct flushing flow can be referred to the technical data of the relevant manufacturer, and can also be calculated according to the heat balance conditions.
