Lubricating oil pump does not drain oil or drain the reasons for less and treatment methods are as follows:
Failure cause:
1.Lubricating oil pump gear and pump Mo loss serious;
2.Suction pipeline leakage;
3.Suction height of lubricating oil pump is too high;
4.Suction pipe blocked or valve closed;
5.The direction of rotation of the lubricating oil pump is not correct;
6.The liquid temperature is low and the viscosity increases;
Treatment method:
1.Remove the check for another piece and replace it;
2.Check whether the lubrication oil pump joint leakage or leakage and add asbestos and other sealing material to seal the village;
3.Preheat the liquid and, if not, reduce the discharge pressure and reduce the oil discharge;
4.Clear the plug, open the lubricating oil pump valve;
5.Correct the steering according to the direction of the pump;
6.Improve the lubrication oil pump suction surface or reduce pipe resistance.
