Abstract
The utility model discloses a pulsator washing machine water seal. The pulsator washing machine water seal comprises a seal body (1), a framework (2) is embedded in the seal body (1), the seal body (1) comprises an internal seal body (11) and an external seal body (12), a first seal lip (111) and a second seal lip (113) are arranged on the internal seal body (11), a spiral spring (3) is mounted in a groove in the rear of the first seal lip (111), a middle seal lip (112) is disposed between the first seal lip (111) and the second seal lip (113), and directions of the first seal lip (111) and the middle seal lip (112) are opposite to the direction of the second seal lip (113). According to the pulsator washing machine water seal, a good sealing performance can be achieved under conditions of high pressure and high rotate speed of a pulsator washing machine.
Description
Technical field
The utility model relates to a kind of rotary drum washing machine water seal, has good sealability under the high pressure of rotary drum washing machine, high-revolving condition.
Background technique
In the prior art, the rotating speed of rotary drum washing machine is high, pressure is high, therefore requires this rotary drum washing machine water seal to have high pressure resistant, high rotating speed, and has good sealability.At present, the rotary drum washing machine water seal of using both at home and abroad although can satisfy sealing under the general condition, along with the development of rotary drum washing machine technology, to improving constantly of seal request, is difficult to guarantee good sealability under high pressure, high-revolving condition.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of rotary drum washing machine water seal, has good sealability under high pressure, high-revolving condition.
For reaching this purpose, the utility model by the following technical solutions:
A kind of rotary drum washing machine water seal, comprise seal, be embedded with skeleton at seal, seal comprises interior seal and external sealed body, be provided with the first seal lip and second lip of seal at interior seal, in the groove at the first seal lip back side, be provided with helical spring, between the first seal lip and second lip of seal, be provided with the intermediate seal lip, the direction of the first seal lip, intermediate seal lip and the opposite direction of second lip of seal.
Preferably, the R value of the first seal lip is constant, and/or the R value of second lip of seal is constant.
Preferably, the height of interior seal and external sealed body equates.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
The design of multiple tracks the first seal lip is adopted in the rotary drum washing machine water seal that the utility model proposes, and can guarantee the excellent sealing effect to axle, and can be to the excellent sealing effect of end face under rotary drum washing machine high pressure, high-revolving condition.
Description of drawings
Fig. 1 is the structural representation of a kind of rotary drum washing machine water seal that the utility model proposes.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
As shown in the figure, Fig. 1 is the structural representation of a kind of rotary drum washing machine water seal that the utility model proposes.
With reference to Fig. 1, a kind of rotary drum washing machine water seal, comprise seal 1, be embedded with skeleton 2 at seal 1, seal 1 comprises interior seal 11 and external sealed body 12, be provided with the first seal lip 111 and second lip of seal 113 at interior seal 11, in the groove at the first seal lip 111 back sides, be provided with helical spring 3, the R value of the first seal lip 11 1 R value constant and/or second lip of seal is constant, between the first seal lip 111 and second lip of seal 113, be provided with intermediate seal lip 112, the first seal lips 111, the opposite direction of the direction of intermediate seal lip 112 and second lip of seal 113.The height of interior seal 11 and external sealed body 12 equates, can further strengthen the sealability of water seal.
In actual course of working, the corresponding shaft shoulder, groove are complementary on the shape of the first seal lip 111, intermediate seal lip 112 and second lip of seal 113 and the axle, to strengthen its sealing effect.In installation process, can add lubricating grease between the first seal lip 111, intermediate seal lip 112 and the second lip of seal 113, thereby form oil film between lower each lip and the axle in working order, when strengthening sealing intensity, keep good lubricated, thereby improved the working life of axle, water seal.
The design of multiple tracks the first seal lip is adopted in the rotary drum washing machine water seal that the utility model proposes, and can guarantee the excellent sealing effect to axle, and can be to the excellent sealing effect of end face under rotary drum washing machine high pressure, high-revolving condition.
For example, the multiple tracks lip design of above-mentioned rotary drum washing machine water seal, still can guarantee good sealability at rotating speed under up to the water column pressure of 1200rpm and 0.8m, and at present this type of domestic water seal can only guarantee its sealing effect under the condition of rotating speed 700-800rpm, thereby under high pressure, high-revolving condition, the rotary drum washing machine water seal has good sealing effect.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as adopted the method design of model utility and the various improvement that technological scheme is carried out; or without improving the design of model utility and technological scheme are directly applied to other occasion, all in protection domain of the present utility model.
