Abstract
The utility model discloses a kind of device for locking Centrufugal compressor impeller, including pedestal and hydraulic jack, the connecting seat for being threadedly coupled with impeller axle is provided with the middle part of the pedestal, the hydraulic jack is fixed on pedestal, and hydraulic jack is symmetricly set on the both sides of connecting seat, the mandrel ends of the hydraulic jack are fixedly installed the jacking block for acting on impeller.The utility model first stretches impeller axle by using hydraulic jack and tightens the mode of locking nut again to reach expected coupling mechanism force, solves the complicated and unhandy problem of locking device structure in the prior art.
Description
Technical field
Compressor field is the utility model is related to, relates in particular to a kind of device for locking Centrufugal compressor impeller.
Background technology
At present, Centrufugal compressor impeller uses doubly linked structure more, and be fastenedly connected for using pretension bolt
Structure, how to ensure to reach expected coupling mechanism force in technique, turn into the problem of assembly technology.Traditional process is to exert oneself
Square spanner tightens locking nut, and this method operation is laborious, and the size of pretightning force is not easy to hold, and easily causes locking screw
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 locking centrifugal compressed
The device of machine impeller, the utility model first stretch impeller axle by using hydraulic jack and tighten the mode of locking nut again to reach
To 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 device for locking Centrufugal compressor impeller, it is characterised in that：Including pedestal and hydraulic jack, the pedestal
Middle part is provided with the connecting seat for being threadedly coupled with impeller axle, and the hydraulic jack is fixed on pedestal, and hydraulic jack
Top is symmetricly set on the both sides of connecting seat, and the mandrel ends of the hydraulic jack are fixedly installed the jacking block for acting on impeller.
The quantity of the hydraulic jack is at least two sets.
The connecting seat is cylinder, and the threaded interior hole coordinated with impeller axle is offered inside it.
The connecting seat is integrally formed on pedestal.
Plastic cushion is fixedly installed on the jacking block.
The jacking block is bolted on push rod.
The jacking block is square or circular.
Using the utility model has the advantage of：
First, the utility model tightens locking nut again after first stretching impeller axle by using hydraulic jack, uses impeller axle
Elastic deformation ensure to reach expected coupling mechanism force, both improved the fixed effect of impeller axle, there is simple in construction, operation again
The advantages that facilitating, solves the complicated and unhandy problem of locking device structure in the prior art.
2nd, the utility model more can gently adjust impeller axle using the structure of at least two sets hydraulic jacks
Deformation force, 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.
4th, jacking block is fixed on the structure on push rod by the way of bolt fixation in the utility model, is advantageous to according to reality
When need to change different jacking blocks, more convenient operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure marked as：1st, pedestal, 2, hydraulic jack, 3, connecting seat, 4, jacking block, 5, plastic cushion, 6, impeller, 7, leaf
Wheel shaft.
Embodiment
Embodiment 1
A kind of device for locking Centrufugal compressor impeller, including pedestal 1 and hydraulic jack 2, the middle part of pedestal 1 are set
There is connecting seat 3, the connecting seat 3 is integrally formed on pedestal 1, and the connecting seat 3 is cylinder, is offered inside it and impeller
The threaded interior hole that axle 7 coordinates, the pedestal 1 are threadedly coupled by the threaded interior hole in connecting seat 3 with impeller axle 7, the hydraulic pressure
Jack 2 is fixed on pedestal 1, and hydraulic jack 2 is symmetricly set on the both sides of connecting seat 3, the top of the hydraulic jack 2
Boom end is fixedly installed the jacking block 4 for acting on impeller 6, and the hydraulic jack 2 coordinates stretching impeller axle 7 with jacking block 4.Its
In, the quantity of the hydraulic jack 2 is at least two sets.
The implementation principle of the present embodiment is：
Pedestal 1 is fixedly connected with impeller axle 7 by connecting seat 3 first, then controls the push rod of hydraulic jack 2 to stretch out,
Jacking block 4 is contacted with impeller 6, then control the push rod of hydraulic jack 2 progressively to stretch out, have the function that to stretch impeller axle 7, reach
Tight locking nut is first dialled after to setting position, then controls the push rod of hydraulic jack 2 to retract, now the stretch section of impeller axle 7 returns
Bullet, but locking nut locking after shaft part can not complete resilience, such impeller axle 7 elastic stretching amount of itself can be to locking nut
Pretightning force is produced, so as to have the function that impeller locking 6.
Embodiment 2
