How to check the installation position of middle oil pump in automobile.

Automobile oil pump is usually installed inside the engine and in the oil pan, which can be seen by uncovering the oil pan. A filter screen is connected below the oil pump, and the part above the filter screen is the oil pump. At present, most vehicle fuel pumps are installed in automobile fuel tanks. The fuel pump driven by electricity consists of pump body, permanent magnet motor and casing. When the permanent magnet motor is energized, it drives the pump body to rotate, sucking fuel from the oil inlet, flowing through the electric fuel pump, and then pressing it out from the oil outlet to supply oil to the fuel system. The fuel flows through the electric fuel pump to cool the armature of the permanent magnet motor, which is also called wet fuel pump. Function of oil pump in lubrication system: The function of oil pump is to increase the oil to a certain pressure and then force it to the moving surface of each part of the engine. For cycloidal rotor pump, the angle range of oil suction and discharge is large. When rotating at high speed, the truck oil pump with centrifugal force is beneficial to the filling of oil in tooth valleys, and will not produce harmful "cavity" phenomenon. Therefore, the rotating speed range of cycloidal rotor pump can be several hundred to nearly ten thousand revolutions. The fuel pump is a professiONal term in the auto parts industry, and it is one of the basic components of the EFI automobile fuel injection system. It is located in the vehicle fuel tank. The fuel pump works when the engine is started and running. If the engine is stopped and the ignition switch is still on, the HFM-SFI control module turns off the power of the fuel pump to avoid accidental ignition. The function of the fuel pump is to suck the fuel out of the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure. Oil pump, which is assembled in oil pan, is the most important component in lubrication system. The function of the oil pump is to send the oil to each friction part of the engine through the oil duct with a certain pressure, so as to lubricate the friction parts and prevent the cab oil pump from causing wear. Generally, an automobile uses an oil pressure gauge or a pressure alarm lamp to monitor whether the oil pressure is normal. Once the pressure alarm lamp is on, it is necessary to immediately shut down the engine for inspection, and then drive after troubleshooting. However, if the oil pump is damaged and does not pump oil, the engine will soon wear out and pull the cylinder (piston and cylinder bite), which requires major repair of the engine. Some manifestations after damage:. 1. When the pump core is damaged, when the fuel supply system works and the key door is opened, there is no sound of the gasoline pump running. 2. When the pump body is damaged, due to pressure relief, the fuel pressure cannot reach the specified fuel pressure value, so that the engine cannot be started. 3. Don't wait until the gasoline lamp gives an alarm and doesn't refuel, because the gasoline pump relies on gasoline to conduct heat and cool down. When the gasoline level is too low, it can't cool down and dissipate heat, thus reducing its service life.
