Cooperation tension between female and impeller axle was pine.
In order to solve the above-mentioned technical problem, Chinese patent notification number was the prior art of " CN201377466 " in 2010
January 6 disclosed a kind of locking device for centrifugal compressor impeller, and its technical scheme is：The impeller includes impeller axle
And the locking nut in impeller axle is threadedly connected to, especially, locking device includes：Piston, its one end are connected through a screw thread
To impeller axle and relative with locking nut；Driving instrument, it is connected with piston, drives piston movement to stretch or discharge impeller axle,
And driving lever, coordinate with locking nut, for tightening locking nut when stretching impeller axle.In actual use, this is special
Although profit can relatively accurately reach expected coupling mechanism force, it is complex and unhandy scarce that it remains structure
Fall into.
Utility model content
The purpose of this utility model is solve the above-mentioned problems in the prior art, there is provided one kind is used for centrifugal compressed
The impeller locking device of machine, the utility model are first stretched by way of impeller axle tightens locking nut again inflation to reach
Expected coupling mechanism force, solves the complicated and unhandy problem of locking device structure in the prior art.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of impeller locking device for centrifugal compressor, it is characterised in that：Including pedestal, guide thimble, inflator and
Inflated hose, the pedestal middle part are provided with the connecting seat for being threadedly coupled with impeller axle, and the guide thimble includes left pipe
With right pipe, the left pipe is fixed on pedestal, and one end of the right pipe is slidably located in left pipe, and the other end, which is provided with, to be acted on
The jacking block of impeller, the inflated hose are arranged in guide thimble, and the inflator is connected by connecting tube with inflated hose.
The quantity of the guide thimble is two, and two guide thimbles are symmetricly set on pedestal.
The connecting seat is cylinder, and the threaded interior hole coordinated with impeller axle is offered inside it.
The jacking block is weldingly fixed on right pipe.
The jacking block is square or circular.
Plastic cushion is fixedly installed on the jacking block.
Using the utility model has the advantage of：
First, the utility model tightens locking again after first stretching impeller axle by expansive force caused by being inflated for inflated hose
Nut, ensure to reach expected coupling mechanism force with the elastic deformation of impeller axle, both improved the fixed effect of impeller axle, had again
The advantages that simple in construction, easy to operate.Wherein, inflated hose is arranged in guide thimble so that inflated hose can only along with
The parallel direction of impeller axle carries out expansion stretching impeller axle, improves the accuracy of stretching impeller axle.
2nd, the utility model sets the structure of two guide thimbles, more can gently adjust the deformation force of impeller axle,
Avoid that impeller axle is caused to damage.
3rd, the plastic cushion that the utility model is set on jacking block can reduce the frictional force of jacking block and impeller, avoid pair
Cause to damage in the surface of impeller.

In figure marked as：1st, pedestal, 2, inflator, 3, inflated hose, 4, jacking block, 5, plastic cushion, 6, impeller, 7, impeller
Axle, 8, connecting seat, 9, Zuo Guan, 10, right pipe.
Embodiment
Embodiment 1
A kind of impeller locking device for centrifugal compressor, including pedestal 1, guide thimble, inflator 2 and inflated hose 3,
The middle part of the pedestal 1 is provided with the connecting seat 8 for be threadedly coupled with impeller axle 7, and the connecting seat 8 is cylindrical, inside it
The threaded interior hole coordinated with impeller axle 7 is offered, the guide thimble includes left pipe 9 and right pipe 10, and the left pipe 9 is fixed present
On body 1, one end of the right pipe 10 is slidably located in left pipe 9, and the other end is provided with the jacking block 4 for acting on impeller 6, described to fill
Gas flexible pipe 3 is arranged in guide thimble, and the inflator 2 is connected by connecting tube with inflated hose 3.
In the utility model, the quantity of the guide thimble is two, and two guide thimbles are symmetricly set on pedestal 1.
Further, the inflator 2 is connected with two inflated hoses 3 respectively by connecting tube.
In the utility model, the jacking block 4 is weldingly fixed on right pipe 10.
The implementation principle of the present embodiment is：
Pedestal 1 is fixedly connected with impeller axle 7 by connecting seat 8 first, the use of inflator 2 is then that inflated hose 3 is inflated,
The inflated hose 3 gradually expanded drives right pipe 10 to be moved to impeller 6, until jacking block 4 is pushed up on impeller 6, with the progress of inflation,
Because pedestal 1 and impeller 6 are relatively-stationary, therefore the inflated hose 3 between pedestal 1 and impeller 6 will gradually draw high leaf
Wheel shaft 7, when being stretched to correct position, tight locking nut is first dialled, then inflated hose 3 is deflated, now the stretch section of impeller axle 7
Resilience, but locking nut locking after shaft part can not complete resilience, such impeller axle 7 elastic stretching amount of itself can be to locking screw
Mother produces pretightning force, so as to have the function that impeller locking 6.
