Fuel pump armature manufacturer introduction What is a fuel pump?

　　 Fuel Pump Armature Manufacturer Introduction: The fuel pump is a technical term in the automotive parts industry. It is one of the basic components of the electronic fuel injection system in fuel-injected vehicles. It is located inside the vehicle's fuel tank, and the fuel pump operates when the engine starts and runs. If the engine stops but the ignition switch remains on, the HFM-SFI control module shuts off the fuel pump power to prevent accidental ignition.

　　Fuel Pump Armature Manufacturer Introduction: The function of the fuel pump is to draw fuel from the fuel tank, pressurize it, and deliver it to the fuel supply pipe, working with the fuel pressure regulator to establish a certain fuel pressure.

　　The high-pressure fuel is delivered to the fuel distribution pipe to ensure continuous fuel supply to the injectors.

　　Fuel Pump Armature Manufacturer Introduction: A fuel pump consists of a motor, a pressure regulator, and a check valve. The motor actually works in the fuel inside the pump housing, so there's no need to worry, as there's nothing inside the housing that can ignite, and the fuel lubricates and cools the fuel motor. A one-way valve is installed at the outlet, and the pressure regulator is located on the pressure side of the pump housing, with a passage leading to the inlet.

　　The ZYB type ignition booster fuel pump is suitable for transporting diesel, heavy oil, residual oil, fuel oil, and other media, especially suitable for fuel pumps of burners in road and bridge engineering mixing stations. It is an ideal replacement for imported products. The ZYB type booster fuel pump is not suitable for transporting highly volatile or low flash point liquids such as ammonia and benzene.

　　Fuel Pump Armature Manufacturer Introduction: When the rotor disc rotates, the rollers are pressed outwards by centrifugal force. Like a rotating oil seal, the rotor rotates, the pump works, drawing fuel from the inlet and pressing it into the fuel system from the outlet. When the pump is closed, the outlet one-way valve closes, preventing fuel from flowing back to the tank through the fuel pump. The fuel line pressure maintained by the one-way valve is called "residual pressure".

　　The higher fuel pump pressure depends on the standard of the pressure regulator. If the fuel pump pressure exceeds the predetermined pressure limit, the pressure regulator will open the bypass, allowing fuel to flow back to the fuel pump inlet.
