The role of automobile gasoline pump
The only thing the automobile gasoline pump does is to pressurize the gasoline in the car's gasoline tank to the fuel supply system of the gasoline engine.
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.
