Abstract
The invention provides a high-pressure gear pump oil distribution disc structure. The high-pressure gear pump oil distribution disc structure is simple, capable of effectively preventing the radial displacement of an oil distribution disc and a pump body and capable of guaranteeing the sealing performance of the oil distribution disc and the pump body. The high-pressure gear pump oil distribution disc structure comprises an oil distribution disc body, wherein an oil inlet hole and an oil outlet hole are formed in the oil distribution disc body, and the high-pressure gear pump oil distribution disc structure is characterized in that grooves, corresponding to the oil inlet hole and the oil outlet hole, are formed in the oil distribution disc body, and a sealing gasket is arranged in each groove.
Description
Technical field
The present invention relates to the technical field of gear pumps parts, be specially a kind of high-pressure gear pump oil distribution casing structure.
Background technology
Gear pump is conventional a kind of power set, its operation principle is to be closed space in rotation by two gears at two at gear pump, the change relying on the swept volume formed between pumping cylinder and meshing gear improves the pressure of liquid and realizes the conveying of liquid, oil distribution casing in high-pressure gear pump is the critical component realizing high-pressure gear pump turnover oil, whether the structure of oil distribution casing rationally directly affects quality and the performance of whole element, oil distribution casing to be connected with the pump housing, existing oil distribution casing to be that monoplane is connected with the pump housing, this connected mode can produce the radial displacement of oil distribution casing and the pump housing, thus have impact on the sealing property of oil distribution casing and the pump housing.
Summary of the invention
For the problems referred to above, the invention provides a kind of high-pressure gear pump oil distribution casing structure, its simple in construction, effectively prevent the radial displacement of oil distribution casing and the pump housing, it is ensured that the sealing property of oil distribution casing and the pump housing.
Its technical scheme is such that a kind of high-pressure gear pump oil distribution casing structure, it includes oil distribution casing body, described oil distribution casing body arranges fuel feed hole and oil outlet, it is characterized in that: corresponding described fuel feed hole and described oil outlet arranged outside groove on described oil distribution casing body, in described groove, be provided with seal washer.
It is further characterized by described oil distribution casing body and is provided with compensating groove；Being provided with multiple oil outlet on described oil distribution casing body, described oil outlet is arranged on described oil distribution casing body side.
In the said structure of the present invention, due to fuel feed hole corresponding on oil distribution casing body and oil outlet arranged outside groove, being provided with seal washer in groove, effectively prevent oil distribution casing will with the radial displacement of the pump housing, it is ensured that the sealing property of oil distribution casing and the pump housing.
Accompanying drawing explanation
Fig. 1 is high-pressure gear pump oil distribution casing structural front view of the present invention；
Fig. 2 is the sectional view of Fig. 1；
Fig. 3 is the rearview of Fig. 1.
Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 3, a kind of high-pressure gear pump oil distribution casing structure, it includes oil distribution casing body 1, arranging fuel feed hole 2 and oil outlet 3 on oil distribution casing body 1, on oil distribution casing body 1, corresponding fuel feed hole 2 and oil outlet 3 arranged outside groove 4, be provided with seal washer 5 in groove 4, due to fuel feed hole corresponding on oil distribution casing body and oil outlet arranged outside groove, being provided with seal washer in groove, effectively prevent oil distribution casing will with the radial displacement of the pump housing, it is ensured that the sealing property of oil distribution casing and the pump housing.
Being provided with multiple oil outlet 3 on oil distribution casing body 1, oil outlet is arranged in oil distribution casing body 1 side, it is ensured that fuel-displaced uniformity.
Oil distribution casing body 1 is provided with compensating groove 6, it is achieved that during pinion rotation, form the pressure off-load of the fluid in pocketed oil district.
