Abstract
The utility model discloses a kind of sealing structure applied to water pump, and in particular to a kind of rubber seal ring with triangle zigzag lip, is mountable between water inlet joint and impeller and between blower inlet casing and impeller.The sealing ring being installed between water inlet joint and impeller, there is lip in inner side and upper surface；And the sealing ring between blower inlet casing and impeller only has lip in inner side.Compared to conventional seals ring, due to which increasing triangle zigzag lip, therefore in the case where not influenceing the relative motion of water inlet joint and impeller or blower inlet casing and impeller, the leakage loss for reducing fluid can be played, balancing axial thrust, improve the effect of operating efficiency.Even if lip is worn, labyrinth seal can be also formed, the sealing effectiveness still having had.This design structure is simple, and cost is low, and install, disassembling section it is simple, time saving and energy saving.
Description
Technical field
The utility model belongs to water pump field, and in particular to a kind of sealing structure applied to water pump.
Background technology
Sealing ring is the important sealing device of water pump, is all needed between water inlet joint and impeller and between blower inlet casing and impeller
Sealing ring is installed.But water pump is in the course of the work, impeller needs to rotate, therefore is rotated for convenience of impeller, reduces
Frictional resistance, it is required for leaving certain gap under normal circumstances between impeller and sealing ring, so will inevitably go out
Existing liquid backflow, phenomena such as leakage loss, while it can also increase the axial force of water pump.But common sealing ring in the market
Mostly conventional seals ring, reduction axial force can be played, the sealing ring of reduction leakage loss effect is seldom, therefore designs a kind of use
It is very necessary in the novel sealing ring of water pump.
Utility model content
The defects of the purpose of this utility model is to overcome prior art, there is provided a kind of simple in construction, good sealing effect, should
Sealing structure for water pump.
To achieve these goals, the technical scheme that the utility model is taken is as follows：
A kind of sealing structure applied to water pump, including the first sealing ring being installed between blower inlet casing and impeller and installation
The second sealing ring between water inlet joint and impeller.
Further improved as the utility model, first sealing ring includes the first sealing ring body and is arranged at the
The zigzag lip of one sealing ring body madial wall.
Further improved as the utility model, second sealing ring includes the second sealing ring body, is arranged at the
First zigzag lip of two sealing ring body madial walls and the second zigzag for being arranged at the second sealing ring body upper surface
Lip.
Further improved as the utility model, the saw tooth section of the first zigzag lip is shaped as positive triangle
Shape, the saw tooth section of the second zigzag lip are shaped as to the inclined obtuse triangle in pump shaft side.
Further improved as the utility model, first sealing ring and the second sealing ring use elastomeric material.
The utility model is a kind of sealing structure applied to water pump, radially fixed in water inlet using the method for interference fit
On section or blower inlet casing, it is installed between water inlet joint and impeller and blower inlet casing and impeller.When pump working, upward fluid is entered
Enter impeller, rotating acting by impeller makes fluid enter blower inlet casing.The sealing ring causes water inlet joint and impeller, blower inlet casing and leaf
Gap between wheel further reduces, and prevents liquid from flowing back, and reduces the leakage loss of fluid.In addition, between water inlet joint and impeller
Sealing ring, for the water flow pressure of upper surface, outside pressure is more than inner side, so upper surface lip is to pump shaft side
Inclined obtuse triangle, this allows for upper surface lip and plays a part of non-return valve.The novel sealing ring uses a period of time
Afterwards, although rubber lip can wear, the sealing ring as labyrinth seal and compare sealing ring effect in the market
It is good.This novel sealing ring design structure is simple, and cost is low, and install, disassembling section it is simple, time saving and energy saving.

Shape lip.
Embodiment
Further details of narration is carried out to the utility model below in conjunction with accompanying drawing.
As shown in accompanying drawing 1-5, a kind of sealing structure applied to water pump, it includes being installed between blower inlet casing 1 and impeller 4
The first sealing ring 3 and the second sealing ring 6 for being installed between water inlet joint 8 and impeller 4.First sealing ring 3 includes first
Sealing ring body 9 and the zigzag lip 10 for being arranged at the madial wall of the first sealing ring body 9.Second sealing ring 6 includes the
Two sealing ring bodies 12, it is arranged at the first zigzag lip 13 of the madial wall of the second sealing ring body 12 and to be arranged at second close
Second zigzag lip 11 of the upper surface of seal ring body 12.The saw tooth section of the first zigzag lip 13 is shaped as positive triangle
Shape, the saw tooth section of the second zigzag lip 11 are shaped as to the inclined obtuse triangle in the side of pump shaft 7.First sealing
The sealing ring 6 of ring 3 and second uses elastomeric material.
When pump working, fluid is moved into impeller 4 upwards by water inlet joint 8, and rotating acting by impeller 4 makes fluid
Into blower inlet casing 1, because the first sealing ring 3 and the second sealing ring 6 all carry equilateral triangle lip, this structure causes water inlet joint 8
Gap between impeller 4 and blower inlet casing 1 and impeller 4 further reduces, and plays a part of preventing liquid from flowing back.Use one section
After time, although rubber lip can wear, the sealing ring as labyrinth seal and compare sealing ring in the market
Effect is good.
Embodiment described above is only preferred embodiment of the present utility model, and the not feasible implementation of the utility model
It is exhaustive.For persons skilled in the art, it is made on the premise of without departing substantially from the utility model principle and spirit
Any obvious change gone out, should all be contemplated as falling with claims of the present utility model.
