Description
Technical Field
The utility model relates to a compressor field especially relates to a compressor and air conditioner.
Background
In both sliding bearings and gas bearings, the bearings generate heat during operation of any machine and require lubrication and cooling. In general, most bearings in the industrial field are cooled by using lubricating oil, which carries away heat generated when a rotating shaft rotates at a high speed relative to the bearing. For a centrifugal compressor, a sliding bearing is generally adopted for a machine type with large cooling capacity, heavy load and low speed, and a gas bearing is generally adopted for a machine type with small cooling capacity, light load and high speed, and in comparison, the calorific value of the gas bearing is lower than that of the sliding bearing.
In the centrifugal compressor, the refrigerant may be used as a cooling medium under a certain condition. Because the refrigerant is relatively easy to volatilize and is extremely easy to gasify after absorbing heat, the refrigerant can be adopted for cooling on some centrifugal compressors using gas bearings under light load.
For the axial bearing cooling problem, the related centrifugal compressor mostly adopts a mode of lubricating oil flowing for cooling. The method is mainly characterized in that lubricating oil enters a gap of a bearing rotating shaft through an oil way to form a certain oil film thickness to support the rotating shaft, and meanwhile, heat generated by friction is absorbed, and the heat generated is taken away by the oil discharged from an oil drainage port; for the dynamic pressure gas bearing, because independent gas supply is not needed, the gas source and the environment are relatively poor in gas fluidity, and the generated heat can be radiated only by means of heat transfer between the environment and metal. This cooling can lead to inside cooling insufficient, and the heat flow is untimely, and there is temperature concentration in the axial bearing inside, can not reach better cooling effect. When the temperature is too high, the phenomena of bearing burnout and thrust surface deformation can be caused.

Optionally, the size of the second inlet 36 is 1mm to 2mm larger than the size of the outlet 37.
In some embodiments, the bearing 4 comprises a gas bearing.
In some embodiments, the bearing 4 comprises an axial bearing.
The axial bearing is one of the core components of the compressor and mainly functions to axially support the rotating shaft 2 which runs at high speed.
Because friction loss exists between the bearing and the thrust surface, a rotating shaft-bearing system generates a large amount of heat in the operation process, if the heat is not taken away in time, not only can the axial bearing be damaged, but also the heat can be transmitted to the thrust surface, so that the thrust surface is deformed, and the performance of the bearing is influenced.

The first bearing 41 and the second bearing 42 are respectively installed at both ends of the thrust disc 5 for balancing an axial force of the rotating shaft 2 operating at a high speed.
As shown in fig. 1, since the first bearing 41 and the second bearing 42 are provided at the same end of the rotating shaft 2, the liquid inlet passage 321 and the liquid outlet passage 322 are provided only in the stationary member 3 at one end of the rotating shaft 2.
In some embodiments, the bearing 4 includes a first bearing 41 and a second bearing 42, and the first bearing 41 and the second bearing 42 are provided at both ends of the rotating shaft 2, and thus, the liquid inlet flow passage 321 and the liquid outlet flow passage 322 are provided at the fixing member 3 located at both ends of the rotating shaft 2.

Further, the space formed by the support 32 arranged at the two ends of the rotating shaft 2 and the inner wall of the shell 1 is a motor cavity 12, and is mainly used for storing the refrigerant after heat exchange with the bearing and guiding the refrigerant to the next link.
In some embodiments, the cooling of the bearing is as follows:
when the bearing is cooled, the refrigerant enters the liquid storage cavity 11, and the pressure of the refrigerant in the liquid storage cavity 11 can be adjusted through the amount of the refrigerant in the cavity. The refrigerant in the reservoir 11 flows through the liquid inlet channel 321 on the support 32 and enters the annular groove or the first annular cavity of the fixing plate 31 under the action of gravity.
The refrigerant flows in the annular groove or the first annular cavity to exchange heat with the outer surface of the bearing 4, and takes away heat through evaporation and heat absorption.
Because the temperature at the second bearing 42 is high, the temperature at the first bearing 41 is low, heat is transferred through the thrust disc 5 to cool the second bearing 42, part of the refrigerant after heat exchange with the bearing 4 is changed into a gas state, and part of the refrigerant is not completely heat exchanged into a liquid state refrigerant, and the refrigerant after heat exchange flows to the motor cavity 12 from the liquid outlet flow channel 322 arranged on the support 32.
The technical scheme provided by the embodiment of the disclosure can effectively solve the problems of overhigh bearing temperature and uneven cooling in the operation process of the rotating shaft of the compressor, ensures that the cooling of the bearing in the compressor is sufficient, and the compressor operates efficiently and reliably.
Some embodiments provide an air conditioner including the compressor described above.
In some embodiments, the air conditioner further comprises a condenser in communication with the inlet channel 321.
