Support thrust bearing 2 in face.The other side of thrust bearing 2 is equipped with thrust disc 7.
Above-mentioned diffuser 3 is integrated with the function of thrust bearing fixed plate, and the bottom surface of the axial inner fovea part 32 of diffuser 3 is straight
It connects and supports thrust bearing 2, positioning action is played to thrust bearing 2.Thrust bearing 2 is directly locked by screw, bears armature spindle
Xiang Li.Stationary plane of the bottom surface of the axial inner fovea part 32 of diffuser 3 as thrust bearing 2, the stationary plane verticality precision is high, makes
It obtaining thrust disc 7 and the air film of 2 mating surface of thrust bearing is uniform, 2 uniform force of thrust bearing slows down the abrasion of thrust bearing 2,
Extend the service life of thrust bearing 2.
The compressor that above-mentioned technical proposal provides reduces number of parts due to the diffuser 3 using above structure,
Improve quality control；In the case where meeting functional requirement, reduce the thickness of thrust bearing fixed plate, turns to reduce
Sub- length not only increases the rigidity of rotor, improves the critical speed of bearing rotor system mode of flexural vibration, decreases rotor
Weight alleviates bearing load, to improve bearing rotor system stability.
In some embodiments, the through-hole wall of diffuser 3 is equipped with sealing element 4.
The speed that impeller 1 exports medium can be converted pressure energy by diffuser 3, and the through-hole wall of diffuser 3 is equipped with sealing
Part 4, sealing element 4 and rotor engagement form axle envelope, prevent impeller 1 from being vented and enter motor cavity.
In some embodiments, sealing element 4 includes sealing comb teeth.
In some embodiments, diffuser 3 and sealing element 4 are integrated.The structure fixes sealing element 4, thrust bearing
Plate and existing diffuser are integrated into a part, and integration degree is high, reduces number of parts, improve quality control；It is full
The length of the part is reduced in the case where sufficient functional requirement, to reduce rotor length, not only improves the rigidity of rotor,
The critical speed for improving bearing rotor system mode of flexural vibration, decreases rotor weight, alleviates bearing load, the two mentions jointly
