Hermetic Decreasing Centrifugal Compressor

Abstract

The invention relates to a closed and decreasing centrifugal compressor. The compressor is provided with a centrifugal wheel, bolt holes are arranged on the centrifugal wheel, and flow passages are arranged on one side of the centrifugal wheel; the centrifugal wheel is connected with the wheel support through bolts; the centrifugal wheel the other end of the disc through a cylinder with a end cap connection, a There is an air intake pipe on the end cover, and one side of the air intake pipe passes through the heat dissipation pipe and the b end cap connection, b A junction box and an exhaust pipe are respectively arranged on the outside of the end cover, b inside the end cap through b The cylinder is connected with the wheel support; b cylinder and a Cylinder through the spring, a bearings, b The bearing and the main shaft are connected; the rotor, the stator and the casing are arranged in turn outside the wheel support; the stator is connected to the terminal in the junction box through wiring; the two ends of the casing are respectively connected to the a end caps and b End cover connection; this compressor overcomes the shortcomings of traditional compressors, and realizes the advantages of high energy efficiency ratio, wide operating voltage range, high air tightness coefficient, and low noise. While saving energy, it improves the use efficiency and prolongs the use life.

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 e...
