cummins nt 855 engine fuel pump
place of origin:
the fuel pump delivers high pressure fuel to the oil distributor to ensure a continuous supply of fuel to the nozzle. the fuel pump consists of electric motor, pressure limiter and check valve.
when the rotor rotating, roller pressure outward by centrifugal force, like a rotary oil seal, the rotor rotation, the pump work, from the fuel oil inlet suction, and the fuel oil from the oil outlet pressure into the fuel oil system, when close the oil pump, oil outlet check valve closed, to prevent fuel through the high pressure fuel pump flow back to the fuel tank, check valve to maintain the fuel pipe pressure is called the "residual pressure". the maximum pump pressure of the high-pressure fuel pump depends on the standard of the pressure limiter. if the pressure of the high-pressure fuel pump exceeds the predetermined pressure limit, the pressure limiter will open the bypass to allow fuel to flow back to the inlet of the high-pressure fuel pump.
