Structure
Fuel pump by an electric motor , pressure limiter , check valve structure, the electric fuel pump motor the actual work of the shell , do not worry , because the shell will not be any ignition stuff , fuel oil can lubricate and cool the motor , the oil port Department equipped with check valves, pressure limiter is located in the pressure side of the pump housing with access to the inlet channel.
Feature
Ignition booster fuel pump for conveying diesel, heavy oil , residual oil, fuel oil and other media, especially for road and bridge projects in the burner mixing station fuel pumps are ideal products to replace imported products.
EFI fuel pump NA transport highly volatile or low flash point of liquids , such as ammonia, benzene.
Works
When the rotor disk rotates , the rollers are pressed outward centrifugal force , like the rotation of the seal , as the rotor rotates, the pump works , inhalation of fuel from the inlet and outlet ports of the fuel from the fuel system pushed , turn off the pump when the check the oil outlet valve closed , preventing the fuel back into the tank through the fuel pump , fuel line pressure check valve is maintained as " residual pressure ."
The maximum pump oil pressure fuel pump depends on the pressure limiter standard, if the fuel pump pressure exceeds a predetermined pressure limit , the pressure limiter will open bypass the fuel back into the fuel pump inlet .
