Brief introduction of fuel pump

The fuel pump delivers high-pressure fuel to the manifold, ensuring a continuous supply of fuel to the injectors.

The fuel pump consists of an electric motor, a pressure limiter, and a check valve. The electric motor actually works in the fuel in the oil pump casing. 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 A check valve is installed at the pump, and a pressure limiter is located on the pressure side of the oil pump housing with a passage to the oil inlet.

ZYB type ignition booster fuel pump is suitable for conveying diesel oil, heavy oil, residual oil, fuel oil and other media, especially suitable for fuel pump of burner in road and bridge engineering mixing station, it is an ideal product to replace imported products. ZYB type booster fuel pump is not suitable for conveying highly volatile or low flash point liquids, such as ammonia, benzene, etc.

When the rotor disc rotates, the roller is pressed outward by centrifugal force, like a rotating oil seal, the rotor rotates, the pump works, sucks fuel from the oil inlet, and presses the fuel from the oil outlet into the fuel system, when the oil pump is turned off , the check valve at the oil outlet is closed to prevent fuel from flowing back to the fuel tank through the fuel pump, and the fuel line pressure maintained by the check valve is called "residual pressure".
