Problems solved by technology

[0003] The installation of the impellers of most compressors currently on the market has the problems of complex structure and inconvenient operation of the locking device. When the impeller needs to be repaired or replaced, it not only needs to waste a lot of time for disassembly, but also is relatively difficult to install. Time-consuming and labor-intensive, therefore, a compressor single-stage impeller is proposed to solve the above problems

Embodiment 1

[0020] see Figure 1-3 , the present invention provides a technical solution:

[0021] A single-stage impeller of a compressor, comprising a lower disc 1, one side of the lower disc 1 is fixedly connected with a connecting shaft disc 4, the inner side of the connecting shaft disc 4 is provided with a fixed rivet 3, and the connecting shaft disc 4 is fixed by the fixed rivet 3 The upper wheel disc 2 is connected, and the connection is made by rivets, so that the installation of the wheel disc is more stable, preventing accidents during use, and its service life is longer. One side of the shaft disk 4 is fixedly connected with long blades 6, and the long and short blades are used together to facilitate the work of compressor air intake and compression. Shaft plate 4, the outer side of the connecting shaft 8 is sleeved with a limit ring 9, and the inner side of the limit ring 9 is spirally connected with an adjusting bolt 10, which has a wide adjustment range and is beneficial t...

Abstract

The invention relates to the technical field of compressors, in particular to a compressor single-stage impeller. The compressor single-stage impeller comprises a lower wheel disc, wherein a connecting shaft disc is fixedly connected to one side of the lower wheel disc, fixing rivets are arranged on the inner side of the connecting shaft disc, an upper wheel disc is fixedly connected to the connecting shaft disc through the fixing rivets, short blades are fixedly connected to one side of the connecting shaft disc, and connecting shafts are arranged on the inner side of the lower wheel disc. According to the compressor single-stage impeller, when the impeller is used, an impeller body can be limited and fixed through the arrangement of fixing plates and the cooperation of the connecting shafts, the contact between the plates and the impeller body can be reduced through protective pads on one sides of the fixing plates, gaps are prevented from being reserved between parts, in addition, when the impeller is installed, the two fixing plates can be effectively connected through the effect of fastening bolts, the impeller body is further limited and fixed, later-period disassembling, maintenance and use are facilitated through the arrangement, the blades with different lengths are arranged on the impeller body, air inlet can be better achieved, the air inlet efficiency is improved, and the working efficiency of the compressor is effectively improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor single-stage impeller. Background technique [0002] The compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, and drives the piston to compress it through the operation of the motor. The high-temperature and high-pressure refrigerant gas is discharged to the exhaust pipe to provide power for the refrigeration cycle. The compressor is regarded as the heart of the refrigeration system. The special term that best expresses the characteristics of the compressor is called "vapor pump". The responsibility of the compressor is to increase the pressure and increase the suction pressure state to the discharge pressure state. The internal parts requirements of different compressors are not the same. Therefore, the ...
