Description
Technical field
The utility model relates to a kind of oil pump changement, belongs to mechanical equipment technical field.
Background technique
It is immutable that oil pump turns in Fuel injection system, and as input redirect is contrary, then oil pump can not realize oil supply function, and air compressor is damaged.When needs change turn to realize fuel feeding time, need oil pump to take off, artificial commutation is reorientated, then installs.Install more loaded down with trivial details, expend time in.
Model utility content
For solving the problem, the utility model provides a kind of structure simple, easy to operate oil pump changement.
The technological scheme that the utility model adopts for its problem of solution is:
A kind of oil pump changement, comprise the pump housing, in the described pump housing, rotating internal rotor is installed, positioning support bracer is arranged with between outside described internal rotor and inside the pump housing, between the side of described positioning support bracer and the inner side of the described pump housing, the outside that is positioned at internal rotor is arranged with eccentric hoop, the outside of described eccentric hoop is arranged with external rotor, and the side of described external rotor is provided with positioning block, and the inner side of the described pump housing is provided with the locating stud abutted with described positioning block.
Preferably, filler opening is provided with outside the described pump housing.
Preferably, the outside of the described pump housing is provided with the sealing gland be socketed in outside described internal rotor.
Preferably, the end of described sealing gland is provided with inipple.
Preferably, the inner side of described sealing gland and the outside of described internal rotor are provided with seal ring.
Preferably, the inside of described internal rotor installation transmission shaft is provided with oil circuit.
Preferably, the described pump housing is provided with observation panel.
The beneficial effects of the utility model are: structure is simple, under the prerequisite of retaining mechanism performance, oil pump can not be dismantled, also can carry out switch operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In figure: 1, the pump housing; 2, filler opening; 3, internal rotor; 4, positioning support bracer; 5, eccentric hoop; 6, external rotor; 7, positioning block; 8, locating stud; 9, sealing gland; 10, seal ring; 11, oil circuit; 12, observation panel; 13, inipple.
Embodiment
A kind of oil pump changement as shown in Figure 1, comprise the pump housing 1, the filler opening 2 connecting outside oil-feeding device is provided with outside the described pump housing 1, be provided with rotating internal rotor 3 in the pump housing 1, the end of described internal rotor 3 is arranged to square, is directly connected with the bent axle of air compressor, pass through crank-driven, and end is provided with rubber seal, thus reduce the joint gap between bent axle, reduce oil pressure loss.Positioning support bracer 4 is arranged with between the outside of internal rotor 3 and the inner side of the pump housing 1, between the side of described positioning support bracer 4 and the inner side of the described pump housing 1, the outside that is positioned at internal rotor 3 is arranged with eccentric hoop 5, the outside of described eccentric hoop 5 is arranged with external rotor 6, the side of described external rotor 6 is provided with semiorbicular positioning block 7, and the inner side of the described pump housing 1 is provided with the locating stud 8 abutted with described positioning block 7.By above-mentioned design, not only achieve the direction conversion of oil pump, and simplify the structure, the pump housing 1 is integrated with bearing support, and internal rotor 3 is directly by the crank-driven of air compressor, and installation, maintenance is convenient.

In order to improve the end part seal of internal rotor 3, the sealing gland 9 be socketed in outside described internal rotor 3 is provided with in the outside of the described pump housing 1, the inner side of described sealing gland 9 and the outside of described internal rotor 3 are provided with seal ring 10, and are also provided with rubber seal between the end face and the end face of the pump housing 1 of sealing gland 9.Like this, the use of easily damaged parts can be reduced as far as possible, but not affect sealing and fuel feeding effect.Inipple 13 is provided with, for installing speed probe in the end of described sealing gland 9.
One end of described internal rotor 3, the inside for installing transmission shaft is provided with oil circuit 11, to carry out fuel feeding to bent axle.
The described pump housing 1 is provided with observation panel 12, checks that whether oil pump is working properly to facilitate staff.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
