Only normal engine oil pressure can ensure that the oil is sent to all the friction surfaces of the engine. Too high or too low will affect the normal operation of the engine, and even cause damage to engine parts. So, when the alarm lamp should be immediately shut down to find out the reasons, troubleshooting before it can continue to work.
The following reasons may make the oil lamp alarm.
1, the amount of oil is insufficient, so that the pump oil pump volume reduced, or because of air into the pump does not oil, resulting in lower oil pressure;
2, Baotou North rush heavy truck parts, engine temperature is too high, easy to make oil become thin, with a large gap in the gap and lead to oil pressure drops;
3, when the oil pump parts damage or wear, assembly and other problems arise when the gap is too large, will cause the oil pump out of oil or the failure of the oil shortage;
4, Baotou North run heavy duty parts, crankshaft and large, small tile gap between the improper, too tight will make the oil pressure rise, too loose will make the oil pressure lower;
5, Baotou North heavy truck parts, oil filters, oil suction disk plug will also reduce the oil pressure;
6, the oil return valve damage or failure: if the main oil return valve spring fatigue softening or improper adjustment, the valve seat and the ball with the surface wear or dirt stuck and closed, the oil return amount will increase obviously, oil pressure of the main oil channel also decreased;
7, improper selection of oil: if you use the wrong or improper selection of grades, the engine will run when the oil viscosity is too low and increase the leakage, thereby reducing the oil pressure.
