Further, some pressure regulating holes are evenly equipped with the impeller hub.
The utility model is also adopted the following technical scheme that：A kind of method of work of the adjustable impeller assembly of axial force, step
It is rapid as follows：
1) adjustable impeller is installed on rotor, and pressure chamber is formed between adjustable impeller and seal disc, in adjustable impeller
On be threaded with pressure regulating bolt and all block pressure regulating hole；
2) after starting shooting, motor speed is stepped up, compressed gas are leaked in pressure chamber, and the pressure of pressure chamber progressively rises
Height, the axially loaded of rotor is incrementally increased, and axial magnetic suspension bearing electric current is incrementally increased, and is judged according to axial magnetic bearing electric current
Rotor axial stressing conditions；
3) when axial magnetic suspension bearing electric current is close to 1.5 times of rated values, then show that pressure chamber internal pressure is too high, cause
Axial force is excessive suffered by rotor, two pressure regulating bolts symmetrical on adjustable impeller is now shut down and take out, then by pressure
High pressure in chamber is guided at adjustable impeller inlet low pressure, reduces the axially loaded of rotor, while in turn ensure that the dynamic balancing of rotor；
4) motor is risen into rotating speed higher, when axial magnetic suspension bearing electric current is again close to 1.5 times of rated values, is shut down simultaneously
Take out two other symmetrical pressure regulating bolt in adjustable impeller；
5) repeat it is above-mentioned 3), 4) the step of, until when motor reaches rated speed, axial magnetic suspension bearing electric current is specified
In the range of ± the 10% of current value, regulation is completed.
The utility model has the advantages that：The utility model is using the pressure regulating bolt and magnetic on adjustable impeller
Suspension bearing current signal, carries out the regulation of rotor part axial force, simple to operate, and when being used in different model equipment not
With redesign, applicability is wide.
Brief description of the drawings：
Fig. 1 is the adjustable blade wheel structure schematic diagram of axial force of the present utility model.
Fig. 2 is that impeller of the present utility model is assembled and axial force regulation schematic diagram.
Specific embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the adjustable impeller assembly of a kind of axial force of the utility model, including adjustable impeller, deflection cone
6th, seal disc 8 and rotor 9, rotor 9 are arranged on seal disc 8, and on rotor 9, deflection cone 6 is threadedly coupled adjustable impeller set
On rotor 9, and adjustable impeller is fixed on rotor.Pressure chamber 10 is formed between the bottom surface of adjustable impeller and seal disc 8,
Some pressure regulating bolts 5 are threadedly coupled on the upper surface of adjustable impeller.
The first sealing tooth 4 is provided with the lower surface of adjustable impeller, is provided with the upper surface of seal disc 8 and the first sealing
The second sealing tooth 7 that tooth 4 is adapted, the first sealing sealing tooth 7 of tooth 4 and second cooperates and seals pressure chamber 10 so that
Pressure chamber 10 forms a closed cavity.
Adjustable impeller includes impeller hub 1 and impeller blade 2, and impeller blade 2 is located on impeller hub 1,1 set of impeller hub
On rotor 9.
Some pressure regulating holes 3 are evenly equipped with impeller hub 1.
The utility model provides a kind of method of work of the adjustable impeller assembly of axial force, and its step is as follows：
