What are the symptoms of low gas pump pressure?
When the motor vehicle is driving, the oil pump under the rear seat sends out a "hum" abnormal sound. 1. Motor vehicles are weak in speed, especially when they speed up rapidly. 2, the operation of motor vehicles often appear not fire, running difficult problems; 3. Engine failure light of motor vehicle combination instrument is steady on.
The rear end oil seal of the shaft sleeve transmission gear of the automobile oil pump is damaged seriously, or the connecting head of the automobile pipeline often has problems. In addition, there is air inside the pipeline, and the automobile oil tank often suffers from oil shortage and other conditions. Basically, all of these are the key factors causing insufficient pressure in the oil pump. Make the axial clearance of the oil pump gear too large, then it will affect the pressure is not enough. The oil pump regulating valve or the safety valve often appears stuck, or the spring elastic force is not enough to break and so on are basically all one of the reasons. When there is often a problem with the oil pump, the first task is that we should judge the specific reasons and implement the treatment according to different reasons. In view of the fault problem, we need to carry out corresponding inspection on the oil transmission amount of the oil pump, trigger condition and check valve, and then carry out repair treatment on the fault problem area according to the inspection results.
