Title:
SUSPENSION CENTRIFUGAL COMPRESSOR AND AIR CONDITIONER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/051099
Kind Code:
A1
Abstract:
A suspension centrifugal compressor, comprising a main shaft (1), an impeller device (2) fixedly mounted on the main shaft (1), and a radial gas bearing (5) and an axial gas bearing (6) which are sleeved on the main shaft (1), wherein the main shaft (1) extends up and down; and when the impeller device (2) rotates, an axial thrust acting on the main shaft (1) is upward. Because the main shaft (1) extends up and down, the axial upward thrust can achieve the effect of overcoming the gravity of the main shaft (1), so that less gravity of the main shaft (1) is borne by the axial bearing, thereby effectively reducing the working pressure of the axial bearing, such as the axial gas bearing (6). In an operating state, the working pressure of the axial gas bearing (6) can be effectively reduced, so that an air supply amount can be reduced, so as to achieve the effect of reducing energy consumption, and the efficiency of the whole machine is increased; in addition, the radial bearing does not need to bear gravity, so the working pressure can also be reduced, and vibration is minimized. Further disclosed is an air conditioner system comprising the suspension centrifugal compressor.
