Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be benchmark with the direction shown in each figure all, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.
Vane-type fuel transfer pump of the present utility model is by setting up secondary spring mechanism on blade structure, make oil transfer pump when running work, blade is under the acting in conjunction of centrifugal force and spring force, can throw away smoothly, it is bad to avoid work occurring under low speed or the low temperature condition, thereby influences delivery efficiency and functional reliability.
As depicted in figs. 1 and 2, this vane-type fuel transfer pump 5 and high pressure oil pump 4 are combined as a whole, and by high pressure oil pump 4 drive vane formula oil transfer pumps 5, its concrete structure comprises: eccentric stator 1, rotor 2 and blade 3; The end cover of eccentric stator 1 is provided with cover plate 11, offers filler opening 12 and oil outlet 13 on the cover plate 11, and rotor 2 is arranged in the eccentric chamber of eccentric stator 1, is connected with high pressure oil pump 4 camshaft actuated by input end 21; Blade 3 is arranged on the rotor 2, during rotor 2 rotations, blade 3 is thrown away from rotor 2 under centrifugal action, and by the eccentric wheel structure of eccentric stator 1 the low pressure diesel oil that enters in the pump chamber by filler opening 12 is pushed, and forms the diesel oil with elevated pressures and exports by oil outlet 13.
Wherein, offering of rotor 2 is some along the outward extending blade installation groove of cross-section radial, and blade 3 is actively plugged in this blade installation groove, and during rotor 2 rotations, blade 3 is thrown pressure oil away from rotor 2 under centrifugal action.The blade installation groove is three to eight.
As shown in Figure 3, blade 3 is three to eight corresponding with the blade installation groove, and every cross section is a rectangle, axially offers down the big little ladder tube chamber of, and its tubule chamber, middle and upper part is an oil pressure equalizing orifice 31, and the big tube chamber in bottom is a spring mounting hole 32.
As shown in Figure 4, when blade 3 is inserted in this blade installation groove, oil pressure equalizing orifice 31 is last, the spring mounting hole 32 that is communicated with oil pressure equalizing orifice 31 is provided with spring 33 down in the spring mounting hole 32, the upper end of spring 33 props up spring mounting hole 32 upper ends, the lower end of spring 33 props up the blade installation bottom land end of rotor 2, during blade 3 retraction blade installation grooves, spring 33 is in compressive state, makes blade 3 be subjected to the restoring force effect that makes progress of spring 33; When rotor 2 rotations, blade 3 under centrifugal action when rotor 2 is thrown away, blade 3 is subjected to the effect of the elastic force that makes progress of spring 33 simultaneously, the situation lower blade that this oil transfer pump is lower in engine speed or ambient temperature is lower, diesel oil viscosity is bigger also can be thrown away, satisfy the requirement of low engine speed or cold-starting.
