Q:The role of automobile gasoline pump

The oil pump is the role of the engine oil to the friction parts, the oil circulation lubrication in the road, in order to ensure good lubrication. The engine oil pump is composed of gear pump, gear pump body and other components. When the engine works, the cam shaft drives the drive gear pump rotation gear oil whip. Along the inner wall of the pump from the oil inlet flow to the outlet, the formation of low pressure, resulting in suction oil inside the oil is sucked into the oil inlet and the oil outlet. The oil product more, thus the pressure increased, the oil will be pressure to the friction part, realize the forced lubrication.

Q:How to change the oil pump 1.8 MAGOTAN

Hello! The best to replace the 4S shop, if the warranty period, can request a free replacement

Q:My car: Chery QiyunTransmission: ManualDisplacement: 1.6 litersMileage: 7 kmPurchase time: September 2002Problem Description: I have a Chery and because I did not pay attention to a few kilometers from the later results cannot flameout repair factory towed to overhaul the results I said no money for a ZWZ the sound of the engine also can now open half machine oil flash engine temperature is very high the garage man said no pressure oil pump is not up to actually change a replacement pump not expensive I fear the garage man pit I would like to ask the people I now understand the point of repair is not for the engine oil pump can be changed ZWZ will soon appear problem solving and my score how to add light fuel oil or not hundreds of state awayBut the overhaul of thousands of car also cannot be worth a few money is not for the oil pump or no repair as the repair factory is the largest side this boss said that one hundred percent is the pump problem for good

You can go to the 4S shop to find out what's wrong and then go out and fix it

Q:How to check the motor oil pump oil supply is normal?

In the premise of the normal amount of oil, usually need to check whether the oil pressure is normal (usually around 0.3MPa), if the oil pressure is low, usually the oil circuit, overflow valve failure or oil pump failure. After cleaning and adjusting the oil relief valve, the pressure is still low. The fault must be the oil pump failure.The effect of the oil pump is to press the engine oil to a certain pressure and force it to the surface of each part of the engine. If the oil pump is damaged or leaking, it is necessary to disassemble the oil pan, take out the oil pump and replace it, and clean or replace the oil pump inlet strainer at the same time.

Q:6140 lathe oil pump, no fuel injection, what is the problem?

Replacing an oil pump can be easy and inexpensive

Q:What's the function of the engine oil pump?

It's the engine oil! Pump oil onto the moving parts! Play a better lubrication!!It is also beneficial to the full circulation of the oil!!

Q:What are the fuel pump inspection items for diesel generator sets?

1), sound and vibration unit's normal operation; 2), output voltage, generator current, frequency, active power, reactive power, excitation voltage, excitation current does not exceed the rated value; 3), the temperature of the engine, bearing temperature, lubrication oil temperature and cooling water temperature were normal; 4) water, oil, cooling water tank is not low; 5), oil pressure is not low; 6), no odor, abnormal alarm.

Q:The car leaked oil, changed a pump, put it up overnight, or a few drops of oil, and called the repair truck. He said it was dirt underneath. It was hot

First of all, it is necessary to make sure that the oil is dripping from there and how many drops can be made at one night. These can be checked out by themselves. The problem of one or two drops at one night is too small. Because change pump that has removed the cylinder, the cylinder and the pump is mat, the mat will not handle drop of oil, and the oil filter is opened, if not installed it will leak if these local oil spills, they will help you to reload.

Q:The car oil pump is broken. What are the problems?

If you lose the oil pressure, the alarm light will go on, and continue driving will cause fatal harm to the engine.Adjustment of oil pressureThe oil pump is classified by the steady discharge of the pump, which means that the maximum pressure must be limited by the relief valve. If the pressure relief valve is not used, the system pressure will rise to a dangerous level, which may cause the engine to be damaged.The oil pressure reducing valve is composed of a valve or a ball and a coil spring. The oil is sucked in the strainer and sent to the oil filter. When the fuel supply pressure increases with the engine speed, the pressure relief valve opens. At this point, the oil enters the inlet side by way of the bypass from the exit side to maintain the specified pressure. Since the stiffness of the spring used on the pressure reducing valve is very accurate, the maximum pressure of the oil pump can be guaranteed. If the stiffness of the spring increases, the oil pressure will increase. But the pump will not increase the amount of oil discharge.In addition, the following factors affect engine oil pressure:1. the speed of the oil pump, the oil pressure increases with the speed increase;2., the viscosity of oil, the greater the viscosity of oil, the higher the oil pressure;3. oil gap, bearing clearance will hinder the oil pump boost. When the bearings wear, it is difficult to form the appropriate pressure.

Q:What parts of motorcycle oil pump are connected with them?

It is connected with the engine crankshaft by the helical gear, turbine spiral rod combination, small chain and so on, and works simultaneously with the engine crankshaft
