The price of different cars is different, the fuel pump is about more than two thousand yuan:
1. The fuel pump is composed of an electric motor, a pressure limiter, and a check valve. The electric motor actually works in the fuel in the oil pump housing. Don't worry, because there is nothing in the casing that can be ignited, the fuel can lubricate and cool the fuel motor, the oil outlet is equipped with a check valve, and the pressure limiter is located on the pressure side of the oil pump casing with a channel leading to the oil inlet;
2. The ZYB ignition booster fuel pump is suitable for conveying diesel, heavy oil, residual oil, fuel oil and other media, especially suitable for the fuel pump of the burner in the road and bridge engineering mixing station. It is an ideal product to replace imported products. ZYB booster fuel pump is not suitable for transporting highly volatile or low flash point liquids, such as ammonia, benzene, etc.;
3. When the rotor disc rotates, the roller is pressed outward by centrifugal force. Like a rotating oil seal, the rotor rotates and the pump works, sucking in fuel from the oil inlet and pressing the fuel into the fuel system from the oil outlet. When the fuel pump is turned off, the inspection valve at the fuel outlet is closed to prevent fuel from flowing back to the fuel tank through the fuel pump. The fuel pipe pressure maintained by the inspection valve is called "residual pressure";
4. The maximum pump pressure of the fuel pump depends on the standard of the pressure limiter. If the pressure of the fuel pump exceeds the predetermined pressure limit, the pressure limiter will open the bypass to allow the fuel to flow back to the fuel pump inlet.
