Q:Bending machine, oil pump motor abnormal sound, what's the matter?
First look at the bending function can not be used, if can use it is no big deal, if not the first check is not the lack of phase, a phase, do not have to check the pump, check the pump and motor or elastic coupling is not a problem, take another look at the rear cover of fan motor is not with fan met. These are checked, and the bending machine can be used, there is no need to worry about what.
Q:Engine room abnormal sound! Excuse me, is this the reason for the oil pump?
The oil shortage caused by the oil pump jam is insufficient
Q:How long will the oil pump lubricate the engine parts after the engine is started?
1-3 minutes, the cold car is usually 3 minutes after refueling, the door started.
Q:Bending machine, cutting machine oil pump broken, how to judge?
Touch the oil, step inside to see if there is any sense of oil absorption.
Q:3000 Zhijun hydraulic top rattled, replaced the hydraulic top oil pump
Hello As you say, you should first make sure that when you change the hydraulic column, you have used the oil to soak. As required, the new hydraulic column should be soaked with oil before installation!
Q:Does the oil pump plug cause less oil?
The oil pump plug will not cause any reduction in engine oil, which will only result in the following two results:1. oil pressure drop, oil flow decreases, the appearance of insufficient lubrication2., serious blockage will cause oil in the oil pipe can not flow, causing the normal operation of the components to form "dry grind", accelerating the wear rate of parts
Q:What are the markings on the fuel pump and the oil pump? They can be recognized at once
The fuel pumps are electric now, with wires or string
Q:Where does the engine oil from the oil pump go?
The oil pump is mounted on the front end of the crankshaft, the crankshaft rotates together with the moment, there are two ring gear meshing, the oil pressure generated by the two ring gear will be squeezed, will follow the road surface to the various parts of the oil lubrication, and then flow back into the oil pan, followed by the pump up, so again
Q:How to solve the blockage of the automobile oil pump?
Gasoline pump, pump can not afford oil, may have the following aspects.1, the circuit is not smooth, this is very good inspection, with Multimeter or test light on the plug, play the motor light, indicating that there is electricity, no lights, indicating circuit failure.2, circuit fault, first check the oil pump, relay and oil pump fuse, when motor, oil pump relay should be pulled in, there is voltage output. If there is no voltage output, consider the oil pump, relay, or computer circuit to the oil pump, or even a drive computer.3, if there is electricity, it is much simpler, pull out the oil pump, the oil pipe, motor. When oil is out, check that the pipe is blocked and the gasoline pump is removed without oil.4, the gasoline pump if there is no foreign body plug, then you can change it directly!
Q:Does the new gasoline pump affect the car?
Oil pressure is not enough, of course, to change, poor oil will lead to sub shaft wear faster. There is no harm in replacing the oil pump
