A kind of efficient electric plunger fuel pump, comprise the plunger valve assembly, the oil-feed assembly, fuel-displaced assembly, coil block and the scaffold that said modules is fixedly connected, oil-feed assembly and fuel-displaced assembly divide oil-feed and the oil outlet end that is located at the plunger valve assembly, oil inlet end is in the left side, oil outlet end is on the right side, coil block is located at the cylindrical of plunger valve assembly, the plunger valve assembly comprises plunger tube, plunger, oiling valve and outlet valve, plunger is movable the setting in plunger tube, it is freely movable inside by outlet valve that the plunger right-hand member is provided with cavity, oiling valve is located at the left end import of plunger tube, be provided with spring between oiling valve and the plunger, it is characterized in that: the length of described plunger tube and the ratio of diameter of bore are greater than 5.Ratio the best of the length of described plunger tube and diameter of bore is between 5.2 to 5.3.
In the said structure, (corresponding plunger also diminishes by the length of increase plunger tube and the ratio of diameter of bore, the diameter of bore of plunger tube to be diminished, weight lightens), and the length of plunger tube increases, because plunger is little, lightweight, the reciprocating electromagnetism merit of required promotion plunger is also little, do not need the setting in the large magnetic field of the large coil of traditional type electric plunger fuel pump, because plunger is little lightweight, so inertia is little, the reciprocating impact force of plunger is also little, and corresponding vibration, noise are also little.Above-mentioned structure has kept the swept volume of plunger pump oil, so can not affect because of the reducing of plunger and plunger tube, alleviating of weight the flow of fuel feeding, can increase on the contrary the pump oil mass, and operating current diminishes simultaneously.
Described plunger tube left end leans on the valve seat of oiling valve, is provided with seal ring between the two and seals.Described oil-feed assembly comprises the oil-feed pedestal, the oil-feed pedestal is enclosed within the plunger tube cylindrical from the left side of plunger tube, the socket end of oil-feed pedestal arranges shoulder hole, carry out axial compression by left pressing plate after placing the O RunddichtringO in the shoulder hole, described fuel-displaced assembly comprises fuel-displaced pedestal, fuel-displaced pedestal is enclosed within the plunger tube cylindrical from the right of plunger tube, the socket end of fuel-displaced pedestal arranges shoulder hole equally, carry out axial compression by right pressing plate after placing the O RunddichtringO in the shoulder hole, left and right sides pressing plate abuts in the left and right sides end face of coil carrier.Above-mentioned design has increased the sealing between plunger tube and the oiling valve, has improved the sealing configuration between oil-feed pedestal, fuel-displaced pedestal and the plunger tube, thus Effective Raise the sealability of plunger fuel pump, and the assembling very simple.
The oil intake nozzle of described oil-feed assembly and oil-feed pedestal are welded to connect, and the oil outlet of described fuel-displaced assembly and fuel-displaced pedestal are welded to connect.Above-mentioned design has solved the Leakage that traditional type electric plunger fuel pump oil intake nozzle and oil-feed pedestal, oil outlet are threaded with fuel-displaced pedestal.
