Abstract
An oil transfer pump sealing structure used for an automobile comprises a tappet rod and a pump body, wherein, a sealing component is arranged between the tappet rod and the pump body; the sealing component comprises a first sealing member and a second sealing member; the first sealing member is a ceramic sealing ring, and the second sealing member is a fluorine rubber sealing ring; the inner lining of the fluorine rubber sealing ring is provided with a graphite sealing gasket which is in plane seal with the ceramic sealing ring; and the ceramic sealing ring and the fluorine rubber sealing ring are in interference fit with the pump body. The sealing structure has the characteristics of good sealing performance, long service life, and the like, and can be used under severe conditions of high temperature, low temperature, and the like, without influencing the service performance of the oil transfer pump.
Description
Technical field
The utility model relates to the sealing configuration of a kind of automobile with oil transfer pump, relates in particular to the sealing configuration of the tappet and the pump housing.
Background technique
With the immediate automobile oil transfer pump of the utility model be the positive displacement oil transfer pump, comprise the piston type active chamber of forming by tappet and plunger, tappet is by the piston engine cam drive, when top dead center moved, enclosed volume increased by lower dead center, formed certain negative pressure, at this moment, in line check valve is opened, fuel-displaced closed check valve, and fuel oil sucks in the enclosed volume from oil pump; Under the effect of plunger at spring, when lower dead center was moved, enclosed volume reduced, and forms certain malleation by top dead center, and at this moment in line check valve is closed, and fuel-displaced one-way valve is opened, and fuel oil is pressed into high pressure oil pump from enclosed volume.For preventing fuel leakage, be provided with Sealing (oil sealing) between the tappet and the pump housing, Sealing in the market adopts the nitrile rubber seal ring mostly, and there are defectives such as leakage rate is big, high and low temperature resistance difference in the nitrile rubber seal ring, thereby influences the sealability and the working life of oil transfer pump.
Summary of the invention
Technical problem to be solved in the utility model provides the sealing configuration of a kind of automobile with oil transfer pump, to overcome the defective that exists in Sealing (oil sealing) use between the existing tappet and the pump housing, makes oil transfer pump keep excellent sealing performance at work.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of automobile is with the sealing configuration of oil transfer pump, comprise the tappet and the pump housing, be provided with black box between the tappet and the pump housing, described black box comprises first Sealing and second Sealing, first Sealing is the ceramic seal circle, second Sealing is a viton seal ring, be lined with the graphite grazing pad in the viton seal ring, graphite grazing pad and ceramic seal circle are plane sealing, and ceramic seal circle and viton seal ring and the pump housing are interference fit.
The beneficial effects of the utility model: because pottery has favorable mechanical performances such as high-low temperature resistant, high abrasion, high hardness, fluorine rubber has better elastic and wear-resisting property, so sealing configuration that adopts both to make up, given full play to the superperformance of these two kinds of materials, have excellent sealing performance and high characteristics such as working life, can under rugged environment such as high temperature and low temperature, use and not influence the usability of oil transfer pump.
