Abstract
The utility model relates to a pump head sealing device. A press flange is hermetically fixed on the left end surface of a pump body through threaded bolts and is sheathed on the pump shaft emptily. A cavity exists among the pump body, the press flange and the pump shaft. The press flange in the cavity is evenly distributed with a spring seat hole which is provided with a spring inside. The outer end of the spring is pushed on a static ring which is sheathed on the pump shaft emptily. The outer cylindrical surface of the static ring is provided with a convex block which is inserted into an axial inner groove of the press flange, and thus, the static ring only can slide in an axial direction corresponding to the press flange. The right end of the static ring is fixed with a left carbon ring. A sealing loop is arranged between the outer cylindrical surface of the static ring and the press flange. The right side of the left carbon ring is provided with a right carbon ring which is appressed with the left carbon ring. The right carbon ring is fixed on the left end of a movable ring which is fixed with the pump shaft through threaded bolts and the sealing loop. The utility model can effectively prevent the condition that a mechanical seal is fixed by impurities such as scale deposit, etc., and can not move, and the impurities such as scale deposit, etc., can be cleaned easily.
Description
(1), technical field
The utility model relates to a kind of water pump pump head seal arrangement.
(2), background technique
Existing water pump pump head seal arrangement, rotating ring are contained on axle or the axle sleeve, axle axle sleeve gets rusty or fouling after, make rotating ring can't axle or axle sleeve axially on slide flexibly, cause rotating ring not contact, the generation water leakage phenomenon with the stationary ring border.If handle this problem, must open pump cover, the foreign material such as incrustation scale that clearing axis puts are wasted time and energy.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of water pump pump head seal arrangement, it can effectively prevent mechanical seal by impurity lockings such as incrustation scale can't be movable situation, and foreign material easy to clean such as incrustation scale.
The technical scheme in the invention for solving the technical problem is: on the left side of the pump housing by the fixing differential of bolt seal, the differential sky is enclosed within on the pump shaft, the described pump housing, between differential and the pump shaft cavity is arranged, uniform spring base hole on the differential in cavity, spring is arranged in the spring base hole, the outer end of spring withstands on the stationary ring, the stationary ring sky is enclosed within on the described pump shaft, the external cylindrical surface of stationary ring has projection, projection is embedded in the axial inside groove of described differential, make stationary ring relatively differential endwisely slip, the right-hand member of stationary ring is fixed left graphite annulus, between the external cylindrical surface of stationary ring and the differential seal ring is arranged, the right side of left graphite annulus have with it near right graphite annulus, right graphite annulus is fixed on the left end of rotating ring, and rotating ring passes through bolt, seal ring and pump shaft are fixed.
Spring base hole on the described differential communicates with the external world by aperture.
Because the effect of spring, left and right graphite annulus can only be close together all the time, and good sealing effect can prevent effectively that mechanical seal can't movable situation by impurity lockings such as incrustation scales.If such situation, available little iron rod and so on instrument stretches into from aperture, spring base hole and directly pushes up on the stationary ring, beats the little iron rod of light shake with hand, stationary ring is contacted with rotating ring to front slide get final product.If locking is more serious, also need not tear pump cover open, unclamp the bolt on the differential, can clear up the differential endoporus, convenient, fast.Spring is external, and spring is not contacted with medium in the pump, and prolong working life.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model partial sectional view.
(5), embodiment
As shown in drawings, by bolt 3 sealing and fixing differentials 4, differential 4 skies are enclosed within on the pump shaft 11 on the left side of the pump housing 8.Between the described pump housing 8, differential 4 and the pump shaft 11 cavity 14 is arranged, uniform spring base hole on the differential 4 in cavity 14 has spring 1 in the spring base hole, and the outer end of spring 1 withstands on the stationary ring 2, and stationary ring 2 skies are enclosed within on the described pump shaft 11.The external cylindrical surface of stationary ring 2 has projection, and projection is embedded in the axial inside groove of described differential 4, make stationary ring 2 relatively differential 4 endwisely slip.The right-hand member of stationary ring 2 is fixed left graphite annulus 6, between the external cylindrical surface of stationary ring 2 and the differential 4 seal ring 5 is arranged.The right side of left side graphite annulus 6 have with it near right graphite annulus 7, right graphite annulus 7 is fixed on the left end of rotating ring 10, rotating ring 10 is by bolt 12, seal ring 9 and pump shaft 11 sealing and fixing.Convenient in order to clear up differential 4 endoporus, the spring base hole on the described differential 4 communicates with the external world by aperture 13.
