2, existing fuel pump only has single import and export oil duct, oil return need be leaned on to drive bucket at the bottom of fuel oil pump assembly to oil, can not be applied to the car load project without oil return system.
3, the turbine of existing fuel pump adopts the turbine of the uniform distribution of blade, due to turbine inherently characteristic, during work, mechanical collision is large, make mechanical vibration and pump housing noise larger, motor cannot meet higher torque demand, under high torque operating conditions, the pump housing produces larger mechanical vibration and high frequency noise.
4, existing fuel pump is without reserved far-end oil suction structure, can not realize far-end oil absorptive function, cannot be applied to saddle-shaped oil tank and comprise the complexity fuel tank of major-minor fuel tank.
Model utility content
The purpose of this utility model is to provide a kind of Electrocontrolled high-pressure fuel pump, and to solve, the output power that existing fuel pump exists is low, service behaviour is unstable, can not be applied to without oil return system, mechanical vibration and high frequency noise greatly and can not realize the technical problem of far-end oil suction.
For achieving the above object, the utility model provides a kind of Electrocontrolled high-pressure fuel pump, comprise: fuel-displaced group is stood, casing group is stood, rotor set is stood, armature shaft and oil-feed group are stood, fuel-displaced group is stood the two ends of standing with oil-feed group and being connected to casing group respectively and standing, vertical and the armature shaft of rotor set be arranged on casing group vertical in, armature shaft stands through rotor set, and armature shaft two end axles stands be connected vertical with oil-feed group respectively with fuel-displaced group, oil-feed group is vertical comprises pump chamber, pump cover and turbine, turbine is arranged between pump chamber and pump cover, and turbine is connected with armature shaft, pump cover is provided with filler opening and interior rail oil outlet, fuel-displaced group vertical comprises oil discharging seat and inserted sheet group is stood, and inserted sheet group is vertical to be arranged on oil discharging seat, oil discharging seat is provided with outer rail oil outlet and far-end inlet port.
According to the Electrocontrolled high-pressure fuel pump described in the utility model preferred embodiment, turbine is non-equidistant turbine, and between the blade of turbine, Unequal distance is arranged.
Working procedure of the present utility model is as follows: after fuel pump connects power supply, and electric current stands through inserted sheet group and flows into the vertical commutator of rotor set.When after the winding coil energising during rotor set is stood, the effect of power is subject in magnetic field, rotor set is vertical rotates around armature shaft, now turbine rotates under the driving of armature shaft between pump chamber pump cover, turbine drives the fuel oil be in pump chamber pump cover oil rail thereupon, and fuel oil flows into from pump cover filler opening, through pump chamber pump cover oil rail, flow out from oil discharging seat outer rail oil outlet from rail oil outlet in pump cover with by outer rail respectively by interior rail, realize fuel delivery function.
The utility model is optimized improvement to existing fuel pump, adopts a filler opening, the double track structure of two oil outlets, makes fuel pump meet higher feed flow and discharge pressure, and can be applied to without oil return system.In addition, the utility model can also realize far-end oil absorptive function, and, adopt non-equidistant turbine, can effectively reduce fuel pump high frequency noise.Compared with prior art, the utility model has the following advantages:
1, this fuel pump oil charging structure adopts a filler opening, the structural type of two oil outlets, and this kind of structure can drive bucket at the bottom of fuel oil pump assembly to oil, also can by engine calls quota fuel.Outer rail oil outlet can meet high pressure fuel oil and export, fuel pump is enable to adapt to heavy-duty motor, improve turbine output rate, meet higher feed flow and the discharge pressure of direct fuel-injection engine, interior rail oil outlet can send fuel oil pump assembly oil-storing barrel back to by not ruing out of remaining fuel oil in the course of the work, ensure pump housing working stability, realize pressing engine calls quota fuel, improve operation of oil pump efficiency further.Further, inside and outside double track can also be applied to without oil return system, applied widely.
