Abstract
The utility model discloses a kind of water conservancy diversion end face seal slots, belong to end face seal field;The technical problem to be solved is that providing one kind to guide high pressure oil into low pressure chamber, the water conservancy diversion end face seal for preventing high pressure oil from leaking;Solve the technical solution that the technical problem uses for:A kind of water conservancy diversion end face seal slot, seal groove side is high pressure chest, side is low pressure chamber, it is provided with drainage trough at seal groove low pressure chamber, drainage trough is connected to high pressure chest and low pressure chamber, for drainage well width with well width is sealed, the high pressure oil to leak enters low-pressure side from high-pressure side along seal groove along drainage trough, avoids high pressure oil and leaks;The utility model can be widely applied to end face seal field.
Description
Technical field
A kind of water conservancy diversion end face seal slot of the utility model, belongs to end face seal technical field.
Background technology
High pressure oil is commonly encountered in existing high-pressure gear pump to leak, and is prevented from leaking mainly by sealing, generally be used
Mostly be O-ring seal, U-shaped sealing ring, V-shaped seal ring, X-shaped sealing ring, y-type seal ring even plus baffle ring, no matter using which kind of
Sealing, is all to prevent high pressure oil from leaking by blocking up, and is had less than Ra3.2, seal groove in the roughness of seal groove of end face seal
Impurity, gasket are irregular, sealing is lined with that impurity, oil pressure are excessively high, surface roughness is less than Ra3.2 or there are the feelings of impurity in end face
Under condition, end face seal can fail, once there is end face seal failure, just will appear high pressure oil and leak, high pressure oil, which leaks, to be caused
Gear pump pressure reduces, and influences the normal work of gear pump.
Utility model content
The utility model overcomes the shortcomings of the prior art, and high pressure oil can be guided to low pressure chamber by providing one kind
In, the water conservancy diversion end face seal that prevents high pressure oil from leaking.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is:A kind of water conservancy diversion end face seal slot, it is close
Sealing groove side is high pressure chest, and side is low pressure chamber, is provided with drainage trough at seal groove low pressure chamber, drainage trough be connected to high pressure chest with it is low
Press chamber.
The drainage well width is same to seal well width.
The utility model has the advantages that compared with prior art:Drainage trough is set on seal groove, can be incited somebody to action
Want that the high pressure oil to leak flows back to low pressure chamber from along seal groove, it is ensured that high pressure oil does not leak.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view of Fig. 1.
Fig. 3 is the A direction views of Fig. 1.
1 it is seal groove in figure, 2 is drainage trough.
Specific implementation mode
As shown in Fig. 1 ~ Fig. 3, a kind of water conservancy diversion end face seal slot 1 of the utility model, 1 side of seal groove is high pressure chest, side
For low pressure chamber, drainage trough 2 is provided at 1 low pressure chamber of seal groove, drainage trough 2 is connected to high pressure chest and low pressure chamber, 2 width of drainage trough are same
1 width of seal groove.
When the utility model is used, this structure, high pressure oil is arranged in the pump housing of high-pressure gear pump and the junction of pump cover
Pressure is excessive, and when end face seal is failed, high pressure oil can leak, and the high pressure oil to leak is moved along seal groove 1, passes through drainage
Slot 2 flows into low pressure chamber, prevents high pressure oil from leaking.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of various changes can be made.
