Sealing between body is mainly completed by conical surface sealing structure；When sealing ring is normal, by inclined-plane in conical surface sealing structure and inclined-plane
The magnitude of interference diminish a bit, in order to the dismounting of pump cover and the pump housing.
Conical surface sealing structure in the application has a two schemes:
One of which is: described conical surface sealing structure includes the bellmouth being arranged on pump cover and the cone being arranged on the pump housing
Shape flange, described tapered flanges is plugged in described bellmouth, and described sealing ring is between described tapered flanges and pump cover.
Another kind is: described conical surface sealing structure includes the tapered flanges being arranged on pump cover and the cone being arranged on the pump housing
Shape hole, described tapered flanges is plugged in described bellmouth, and described sealing ring is between described tapered flanges and the pump housing.
Further, the described pump housing having inner chamber, the bottom of described inner chamber offers dead eye, fuel feed hole and fuel-displaced
Hole, the bottom of described inner chamber offers the passage for being connected by oil outlet with dead eye, and when operation of oil pump, passage can will go out
Oil in oilhole introduces in dead eye, is lubricated the bearing in dead eye and the heat of band bearing running, can effectively carry
The service life of this oil pump high.
Preferably, the described pump housing and pump cover are all in column type.
The beneficial effects of the utility model are: comprehensive ne-leakage grease pump of the present utility model uses at the pump housing and pump
It is provided with sealing ring and conical surface sealing structure between lid, is worked in coordination with by sealing ring that conical surface sealing structure is dual ensure that pump cover and pump
Sealing between body, significantly improves the stability that oil pump runs.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
Embodiment 1
As Figure 1-3, a kind of comprehensive ne-leakage grease pump, the pump cover 2 being located on the pump housing 1 including the pump housing 1 and lid,
The pump housing 1 and pump cover 2, all in column type, are provided with sealing ring 3, are additionally provided with between the pump housing 1 and pump cover 2 between the pump housing 1 and pump cover 2
The inclined-plane conical surface sealing structure to inclined-plane, has certain magnitude of interference between inclined-plane and the inclined-plane of conical surface sealing structure, this magnitude of interference
Along with pump cover 2 increases with drawing close of the pump housing 1.
Conical surface sealing structure includes the bellmouth 5 being arranged on pump cover 2 and the tapered flanges 4 being arranged on the pump housing 1, taper
Flange 4 is plugged in bellmouth 5, and sealing ring 3, between tapered flanges 4 and pump cover 2, tapered flanges 4 offers for fixed
The annular groove 401 of position sealing ring 3, sealing ring 3 is positioned at annular groove 401.
Having inner chamber 101 on the pump housing 1, the bottom of inner chamber 101 offers dead eye 102, fuel feed hole 103 and oil outlet 104,
