Description
Technical field
This utility model is related to pump with paying impeller sealing arrangement technical field, and specifically a kind of pump is with paying impeller stop seal
Device.
Background technology
Existing pump, with paying impeller sealing arrangement in the running due to the effect of pressure, can form good sealing, that is, outer
Portion's pressure is more than pressure in pump, so liquid will not leak, the problem without having to worry about leakage in pump full-speed operation.But work as pump
Stop unit turning, losing power is that in pump, pressure and pump external pressure can reach poised state, if abrasion in impeller shaft
The situation of leakage occurs, conventional way is using temporary sealing circle or to allow pump be in low speed rotation state, the first way
Waste time and energy, and sealing effectiveness is poor, later approach energy consumption is higher, and it is larger to the loss of pump, and therefore both of which has greatly
The drawbacks of.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pump with paying impeller parking sealing arrangement, existing to solve
Technology impeller body is had to turn the problem of rear leakage.
This utility model solve technical problem technical scheme be：A kind of pump is with paying impeller parking sealing arrangement, device bag
Include cushion rubber 1, cushion rubber 1 outer wall is provided with the centrifugation glueballs 2 being evenly distributed, centrifugation glueballs 2 is connected with cushion rubber 1 by glue post 3, cushion rubber
1 is arranged on impeller shaft, and impeller shaft is provided with stationary ring 6, and cushion rubber 1 is located at and stops rear.
Pulling force return bar 4 is had on cushion rubber 1, one end of pulling force return bar 4 is connected with cushion rubber 1, and the other end is connected with glue post 3.
Impeller shaft is provided with spacing collar 7, and spacing collar 7 is located at cushion rubber 1 rear.
The inwall of cushion rubber 1 is provided with V shape groove 5, and V shape groove 5 is located at immediately below glue post 3.
The forward edge of cushion rubber 1 is in arc-shaped.
The posterior edges of cushion rubber 1 are in upwarp shape.
Centrifugation glueballs 2 is hollow structure.
It is filled with, in centrifugation glueballs 2, the ball that hard thing is made.
It is filled with liquid, liquid is saline in centrifugation glueballs 2.
It is filled with iron ball in centrifugation glueballs 2.
The beneficial effects of the utility model are：Cooperate between cushion rubber 1, centrifugation glueballs 2, glue post 3, held using rubber
Easily there is elastic deformation characteristic, in high-speed rotation, centrifugation glueballs 2 can produce centrifugal force, by glue post 3 in connection
Outwards lifting cushion rubber 1, thus allowing the forward edge of cushion rubber 1 to separate with stationary ring 6, thus producing air, due in pump when pump operates
Pressure is less, so can avoid seepage using pressure reduction.When pump shuts down, the centrifugation glueballs 2 losing centrifugal force stops lifting
Glue post 3, cushion rubber 1 elastic reset, the forward edge of cushion rubber 1 will form sealing structure with stationary ring 6.The forward edge of cushion rubber 1 sets
It is set to arc-shaped little with stationary ring 6 contact area, so can accelerate to seal the speed with unpacking, posterior edges are in upwarp shape can increase
Stability and adhesive force, thus cushion rubber 1 will not be pullled to disengaging impeller shaft.Pulling force return bar 4 can play Protection glue post 3
Effect, can effectively prevent pump ultrahigh speed rotation when glue post 3 fracture.The design of V shape groove 5 can play the work of cooperation deformation
With, outer force deformation can be converted into mechanism's change, this can effectively prevent cushion rubber 1 because external force excessively pull generation can not inversion
Shape, can also improve conversion rate simultaneously, that is, the sensitivity of whole device is greatly improved.Centrifugation glueballs 2 be hollow structure, from
It is difficult when mental and physical efforts are larger to be torn it is adaptable to rotating speed is higher, perpendicular to the less pump of axial vibration.It is filled with centrifugation glueballs 2
The ball that hard thing is made, also can produce deformation it is adaptable to rotating speed is relatively low when centrifugal force is less, less perpendicular to axial vibration
Pump.It is filled with liquid, liquid is saline, in the case that centrifugal force is moderate, can offset shaking of vertical direction in centrifugation glueballs 2
Move it is adaptable to rotating speed is relatively low, perpendicular to the pump that axial vibration is larger.It is filled with iron ball in centrifugation glueballs 2, moderate in centrifugal force
In the case of, the vibration of parallel direction can be offset it is adaptable to rotating speed is relatively low, parallel to the pump that axial vibration is larger.
