AI Technical Summary
The back pressure in the back pressure chamber of the sealing device of the low-pressure chamber scroll compressor is significantly affected by the pressure fluctuation introduced from the compression chamber of the pump body, which affects the sealing performance and operational reliability.
A throttling channel is used to connect the exhaust space of the low-pressure chamber compressor with the back pressure chamber. The back pressure in the back pressure chamber is stabilized by the design of the throttling channel. Combined with the oil inlet channel and oil collection ring groove set in the stationary scroll plate, the lubrication effect is enhanced, and the sealing performance is ensured by a specific sealing ring structure.
It improves the sealing performance of the axial floating seal assembly and the operational reliability of the compressor, extends its service life, and enhances the compressor's working performance and efficiency.
