Abstract
The utility model provides a kind of high-pressure gear pump oil distribution casing structure, its structure is simple, effectively prevent the radial displacement of oil distribution casing and the pump housing, ensure that the sealability of oil distribution casing and the pump housing, it comprises oil distribution casing body, described oil distribution casing body arranges oil inlet hole and oil outlet, it is characterized in that: corresponding described oil inlet hole and described oil outlet arranged outside groove on described oil distribution casing body, be provided with seal washer in described groove.
Description
Technical field
The utility model relates to the technical field of gear pumps parts, is specially a kind of high-pressure gear pump oil distribution casing structure.
Background technique
Gear pump is conventional a kind of power plant, its working principle is rotated in two enclosed spaces by two gears at gear pump, rely on the change of the swept volume formed between pumping cylinder and engaging gear to improve the pressure of liquid and to realize 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 the quality and performance of whole element, oil distribution casing will be connected with the pump housing, existing oil distribution casing will be that single plane is connected with the pump housing, this Placement can produce the radial displacement of oil distribution casing and the pump housing, thus have impact on the sealability of oil distribution casing and the pump housing.
Summary of the invention
For the problems referred to above, the utility model provides a kind of high-pressure gear pump oil distribution casing structure, and its structure is simple, effectively prevent the radial displacement of oil distribution casing and the pump housing, ensure that the sealability of oil distribution casing and the pump housing.
Its technological scheme is such: a kind of high-pressure gear pump oil distribution casing structure, it comprises oil distribution casing body, described oil distribution casing body arranges oil inlet hole and oil outlet, it is characterized in that: corresponding described oil inlet hole and described oil outlet arranged outside groove on described oil distribution casing body, be provided with seal washer in described groove.
It is further characterized in that: described oil distribution casing body is provided with compensating groove; Described oil distribution casing body is provided with multiple oil outlet, and described oil outlet is arranged on described oil distribution casing body side.
In said structure of the present utility model, due to oil inlet hole corresponding on oil distribution casing body and oil outlet arranged outside groove, in groove, be provided with seal washer, effectively prevent oil distribution casing will with the radial displacement of the pump housing, ensure that the sealability of oil distribution casing and the pump housing.
Accompanying drawing explanation
Fig. 1 is the utility model high-pressure gear pump oil distribution casing structural front view;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the rear view of Fig. 1.
Embodiment
