Problems solved by technology

Because the coils of the motor are all wound with copper wires, and ammonia has a strong corrosion on copper, therefore, the refrigeration compressor with the existing structure cannot use ammonia as the refrigerant

Embodiment Construction

[0013] figure 2 It is a schematic diagram of the structure of the rolling rotor refrigeration compressor of the present invention. The refrigeration compressor of the present invention includes an electric motor 3, a magnetic coupling 2 and a compression device 1. The electric motor 3, the magnetic coupling 2 and the compression device 1 are arranged vertically from top to bottom. A flange 31 is provided at the lower end of the motor 3. A coupling housing 4 is provided outside the magnetic coupling 2, and the coupling housing 4 protects and supports the magnetic coupling 2. The upper end of the coupling housing 4 is provided with a flange 41 that matches the flange 31, and the motor 3 and the coupling housing 4 are fastened together by bolts through the flange 31 and the flange 41. The magnetic coupling 2 includes an outer magnet 21, an outer magnet protective sleeve 22, an inner magnet 23, an inner magnet protective sleeve 24, a shield sleeve 25, an upper bearing 26 and a l...

Abstract

The invention discloses a rolling rotor type refrigeration compressor, comprising an air inlet pipe, an air outlet pipe, a motor and a rolling rotor type compression device, wherein a magnetic coupling is connected between the motor and the rolling rotor type compression device. The magnetic coupling consists of a shield cover, the opening part of the shield cover is fixedly arranged the mouth ofthe case of the rolling rotor type compression device, and forms a sealing cavity with the case of the compression device. Ammonia can be used as refrigerant of the compressor, the atmospheric ozone layer is not damaged, and no greenhouse effect is caused, therefore, the invention has good environment protection effect. The compressor can be applied to domestic small air conditioners, as well as other fields needing gas compression and including refrigeration.

Description

technical field [0001] The invention relates to a refrigeration compressor, in particular to a rolling rotor refrigeration compressor. Background technique [0002] Most of the current refrigeration compressors use Freon as the refrigerant. In order to reduce the greenhouse effect and protect the atmospheric ozone layer, people are trying to replace Freon with low-pollution, environmentally friendly substances. Ammonia is one of the very few working fluids that have no effect on the ozone layer of the atmosphere and have no effect on the global warming effect, and it is cheap and efficient to use as a refrigerant. However, ammonia vapor has a corrosive effect on copper and copper alloys (except phosphor bronze). Therefore, copper and copper alloys cannot be used in ammonia refrigeration systems. In addition, ammonia is highly toxic. Once leaked, it will pollute the air, food, and irritate people's eyes and respiratory organs. Due to the above disadvantages, ammonia is sel...
