Abstract
The utility model belongs to vortex pump technical field, refer in particular to a kind of asymmetrical type bellows being applicable to vortex pump, comprise cylindric bellows body, bellows body two ends are provided with the flanging be connected with movable orbiting scroll or pump case respectively, the middle part of bellows body forms land, the bellows body of the land left and right sides is provided with corrugated part, corrugated part is that bellows body sidewall alternately forms peak portion and valley vertically, wherein, on the left of land bellows body length > land on the right side of the length of ripple tube body.The utility model is asymmetric bellows, before and after its wave number asymmetric (namely, when Bellows Length limits, land in the middle part of bellows is shifted to drive motor side), when can reduce spindle operation, bellows gives the resistance of motor, improve drive motor effectively to transmit, pump performance is got a promotion.
Description
Technical field
The utility model belongs to vortex pump technical field, refers in particular to a kind of asymmetrical type bellows being applicable to vortex pump.
Background technique
At present, be usually equipped with bellows in vortex pump, bellows plays connection eddy spinner disk at pump structure, main shaft, the effect of pump case, when drive main spindle is rotated, prevent the rotation of eddy spinner disk, beat can be made by the throw of eccentric of main shaft to rotate, and the evacuated chamber of rotary bearing and pump is isolated, prevent bearing oil by vacuum sucking-off, need point out, existing bellows is bilateral symmetry, and it is unfavorable in the course of the work, reduces the resistance rotating torque.
Summary of the invention
The purpose of this utility model is to provide a kind of asymmetrical type bellows being applicable to vortex pump, to overcome the problems referred to above.
The purpose of this utility model is achieved in that
A kind of asymmetrical type bellows being applicable to vortex pump, comprise cylindric bellows body, bellows body two ends are provided with the flanging be connected with movable orbiting scroll or pump case respectively, the middle part of bellows body forms land, the bellows body of the land left and right sides is provided with corrugated part, corrugated part is that bellows body sidewall alternately forms peak portion and valley vertically, wherein, on the left of land bellows body length > land on the right side of the length of ripple tube body.
Ripple minister degree on the right side of corrugated part length > land on the left of described land.
The utility model gives prominence to compared to existing technology and useful technique effect is:
The utility model is asymmetric bellows, before and after its wave number asymmetric (namely, when Bellows Length limits, land in the middle part of bellows is shifted to drive motor side), when can reduce spindle operation, bellows gives the resistance of motor, improve drive motor effectively to transmit, pump performance is got a promotion.

Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing:
A kind of asymmetrical type bellows being applicable to vortex pump, comprise cylindric bellows body, bellows body two ends are provided with the flanging 23 be connected with movable orbiting scroll or pump case respectively, 26, the middle part of bellows body forms land 21, the bellows body of land 1 left and right sides is provided with corrugated part, corrugated part is that bellows body sidewall alternately forms peak portion 25 and valley 24 vertically, wherein, on the left of land bellows body length > land on the right side of the length of ripple tube body.
Ripple minister degree on the right side of corrugated part length > land on the left of described land.
Namely, the present embodiment adopts the asymmetric bellows of left and right wave number, when Bellows Length limits, land in the middle part of bellows is shifted to drive motor side, when can reduce spindle operation, bellows gives the resistance of motor, improve drive motor effectively to transmit, pump performance is got a promotion;
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
