Abstract
The invention discloses a lateral plate structure of a high-pressure gear pump. The lateral plate structure is simplified in structure so that the radial displacement of the lateral plate and the pump body can be effectively prevented and the sealing performance of the lateral plate and the pump body is ensured. The lateral plate structure comprises a lateral plate body on which two gear shaft holes are formed; and a sealing slot is arranged on one side of each gear shaft hole, wherein grooves are respectively arranged on one side of the periphery of the gear shaft hole, and a sealing washer is arranged in the groove.
Description
Technical field
The present invention relates to gear pumps parts technical field, be specially a kind of side plate of high pressure gear pump 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, side plate of high pressure gear pump is the critical component of high-pressure gear pump, whether the structure of side plate rationally directly affects quality and the performance of whole element, side plate to be connected with the pump housing, existing side plate to be that monoplane is connected with the pump housing, this connected mode can produce side plate will with the radial displacement of the pump housing, will with the sealing property of the pump housing thus have impact on side plate.
Summary of the invention
For the problems referred to above, the invention provides a kind of side plate of high pressure gear pump structure, its simple in construction, effectively prevent side plate will with the radial displacement of the pump housing, it is ensured that side plate will with the sealing property of the pump housing.
Its technical scheme is such that a kind of side plate of high pressure gear pump structure, it includes side plate body, described side plate body arranges two gear shaft holes, corresponding described gear shaft holes side is provided with seal groove, it is characterized in that: side, described gear shaft holes periphery is respectively provided with groove, is provided with seal washer in described groove.
It is further characterized by described side plate body the back side of corresponding described seal groove and is provided with compensating groove；Described seal groove is separately positioned in the scope of the 2/3 of described gear shaft holes, and described seal groove connects.
In the said structure of the present invention, owing to side plate body arranging two gear shaft holes, side respectively, gear shaft holes periphery is respectively provided with fluted, seal washer it is provided with in groove, when side plate is connected with the pump housing, protruding connecting groove corresponding on the pump housing, effectively prevent side plate will with the radial displacement of the pump housing, it is ensured that side plate will with the sealing property of the pump housing.
Accompanying drawing explanation
Fig. 1 is side plate of high pressure gear pump 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 side plate of high pressure gear pump structure, it includes side plate body 1, side plate body 1 arranges two gear shaft holes 2-1,2-2, corresponding gear axis hole 2-1,2-2 side is provided with seal groove 3-1,3-2, side, gear shaft holes 2-1,2-2 periphery is respectively provided with groove 4-1,4-2, seal washer 5-1,5-2 it is provided with in groove 3-1,3-2, when side plate is connected with the pump housing, protruding connecting groove corresponding on the pump housing, effectively prevent side plate will with the radial displacement of the pump housing, it is ensured that side plate will with the sealing property of the pump housing.
On side plate body 1, the back side of corresponding seal groove 2-1,2-2 is provided with compensating groove 6, it is achieved that form the pressure off-load of the fluid in pocketed oil district during pinion rotation.
Seal groove 3-1,3-2 are separately positioned in the scope of the 2/3 of gear shaft holes 2-1,2-2, and seal groove 3-1,3-2 connect, it is ensured that a side seal in the pump housing, and fluid is extruded by gear from opposite side, form high-pressure fluid.
Claims (3)
1. a side plate of high pressure gear pump structure, it includes side plate body, and described side plate body arranges two gear shaft holes, and corresponding described gear shaft holes side is provided with seal groove, it is characterized in that: side, described gear shaft holes periphery is respectively provided with groove, is provided with seal washer in described groove.
2. a kind of side plate of high pressure gear pump structure according to claim 1, it is characterised in that: on described side plate body, the back side of corresponding described seal groove is provided with compensating groove.
