Abstract
The utility model discloses a kind of fuel pump with low-pressure continuous access slot, include motor, the pump housing, shell, described motor, the pump housing are arranged in fuel pump shell, the described pump housing include successively be connected go out oiled-plate method, pump leaf, oil-feed plate and oil-feed plate lid, it is characterized in that: the end face that described oil-feed plate contacts with pump leaf is provided with C type oil groove, and one end bore of C type oil groove is greater than the other end bore, heavy caliber port is oil-feed low pressure area, small-bore port is fuel-displaced zone of high pressure, is provided with the connecting groove being communicated with low pressure area and zone of high pressure between described C type oil groove two-port.The utility model adds bar connecting groove at oil-feed plate hight nip and low pressure area, utilizes the relation of fluid pressure and flow velocity, makes high pressure oil pump be converted to low pressure fuel pump, improves conventional low oil pump efficiency, reduces rotating speed, reduces mechanical wear, increases component universality.
Description
Technical field
The utility model relates to a kind of improvement invention of low-pressure fuel pump, particularly relates to a kind of improvement invention of the fuel pump with low-pressure continuous access slot.
Background technique
In prior art, oil groove set on the oil-feed plate of traditional low-pressure fuel pump contains zone of high pressure and low pressure area, but zone of high pressure and low pressure area do not have extra connection channel, make cannot mutually transform between the fluid pressure of zone of high pressure and low pressure area and flow velocity, therefore high pressure oil pump can only produce high oil pressure, cannot change low pressure fuel pump into, and the utility model aims to provide a kind of novel oil-feed plate, realize high pressure oil pump and be converted into low pressure fuel pump, strengthen the versatility of component.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of fuel pump of rational in infrastructure, convenient and practical band low-pressure continuous access slot.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme to realize: the fuel pump of this kind of band low-pressure continuous access slot, include motor, the pump housing, shell, described motor, the pump housing is arranged in fuel pump shell, the described pump housing include successively be connected go out oiled-plate method, pump leaf, oil-feed plate and oil-feed plate lid, it is characterized in that: the end face that described oil-feed plate contacts with pump leaf is provided with C type oil groove, and one end bore of C type oil groove is greater than the other end bore, heavy caliber port is oil-feed low pressure area, small-bore port is fuel-displaced zone of high pressure, the connecting groove being communicated with low pressure area and zone of high pressure is provided with between described C type oil groove two-port.
The degree of depth of described connecting groove and joint, zone of high pressure is deeper than the degree of depth of connecting groove and joint, low pressure area.
The beneficial effects of the utility model are fuel pumps of the band low-pressure continuous access slot after improving, bar connecting groove is added at oil-feed plate hight nip and low pressure area, utilize the relation of fluid pressure and flow velocity, high pressure oil pump is made to be converted to low pressure fuel pump, improve conventional low oil pump efficiency, reduce rotating speed, reduce mechanical wear, increase component universality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model oil-feed plate.
Fig. 2 is the structural drawing of the utility model oil-feed back.
Fig. 3 is the A-A sectional drawing of the utility model connecting groove.
Embodiment
Drawings illustrate structure of the present utility model, further illustrate its details by reference to the accompanying drawings more below.The fuel pump of this band low-pressure continuous access slot, include motor, the pump housing, shell, described motor, the pump housing are arranged in fuel pump shell, the described pump housing include successively be connected go out oiled-plate method, pump leaf, oil-feed plate 1 and oil-feed plate lid, the described oiled-plate method that goes out is arranged on electric machine main shaft by oil-impregnated bearing; Described pump leaf is fixedly assemblied on electric machine main shaft; Described oil-feed plate 1 by jacking block and described pump leaf, go out oiled-plate method and be assembled together; Described oil-feed plate mounts cover and fits over oil-feed plate 1 rear end, the end face that described oil-feed plate 1 contacts with pump leaf is provided with C type oil groove 2, and one end bore of C type oil groove 2 is greater than the other end bore, heavy caliber port is oil-feed low pressure area 3, small-bore port is fuel-displaced zone of high pressure 4, be provided with the connecting groove 5 being communicated with low pressure area 3 and zone of high pressure 4 between described C type oil groove 2 two-port, and described connecting groove 5 is deeper than the degree of depth of connecting groove 5 and joint, low pressure area 3 with the degree of depth of joint, zone of high pressure 4.The utility model adds bar connecting groove 5 at oil-feed plate hight nip 4 and low pressure area 3, utilizes the relation of fluid pressure and flow velocity, makes high pressure oil pump be converted to low pressure fuel pump, improves conventional low oil pump efficiency, reduces rotating speed, reduces mechanical wear, increases component universality.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
