Seal decreasing centrifugal compressor

Abstract

The invention relates to a seal decreasing centrifugal compressor. The compressor is provided with a centrifugal disc. Bolt holes are formed in the centrifugal disc. A runner is arranged on one side of the centrifugal disc. The centrifugal disc is connected with a disc support through bolts. The other end of the centrifugal disc is connected with an end cover a through an air cylinder a. An air inlet pipe is arranged on the end cover a. One side of the air inlet pipe is connected with an end cover b through a radiating pipe. A junction box and an exhaust pipe are respectively connected to the outside of the end cover b. The inside of the end cover b is connected with the disc support through an air cylinder b. The air cylinder b is connected with the air cylinder a through a spring, a bearing a, a bearing b and a spindle. A rotor, a stator and a shell are sequentially disposed outside of the disc support. The stator is connected with a binding post in the junction box through a wire. Two ends of the shell are respectively connected with the end cover a and the end cover b. The compressor has the advantages that the defects of traditional compressors are overcome, high energy efficiency ratio, wide working voltage range, high airtight coefficient, low noise, and the like are achieved, utilization efficiency is increased while energy is saved, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to an air conditioner compressor, in particular to a hermetic decreasing centrifugal compressor capable of realizing high energy efficiency ratio, low noise and long service life. Background technique [0002] At present, the known air conditioner compressor is the core component of the air conditioner, and its performance indicators in various aspects are the main standards to measure the quality of the air conditioner. According to the working principle, it can be divided into reciprocating compressor, positive displacement compressor and centrifugal compressor. etc. Although the traditional volumetric gas compressor and reciprocating gas compression have a relatively high airtight coefficient, due to the large friction between the parts in the volumetric gas compressor and the reciprocating gas compression machine, And these friction forces undoubtedly consume a lot of energy, plus the gap loss, resulting in a very low energy ...
