Embodiment 1

[0034] Such as figure 1 As shown, the compressor of the first embodiment includes a casing 10 and a crankshaft 20 disposed in the casing 10 , and the compressor also includes a first magnetic suspension bearing 30 and a second magnetic suspension bearing 40 . Wherein, the first magnetic suspension bearing 30 is arranged in the casing 10 . The second magnetic suspension bearing 40 is arranged in the housing 10 , and the first magnetic suspension bearing 30 and the second magnetic suspension bearing 40 are respectively arranged at two ends of the crankshaft 20 .

[0035] During the operation of the compressor, the first magnetic suspension bearing 30 and the second magnetic suspension bearing 40 play the role of supporting and positioning the crankshaft 20, preventing the crankshaft 20 from moving in the radial and axial directions relative to the housing 10 during the rotation process. . In this way, the first magnetic suspension bearing 30 and the second magnetic suspension ...

Embodiment 2

[0055] The difference between the compressor of the second embodiment and the first embodiment lies in that the structure of the compressor is different.

[0056] Such as Figure 5 As shown, in this embodiment, the compressor further includes a bearing structure 100 . Wherein, the bearing structure 100 is arranged on the crankshaft 20 , and the bearing structure 100 is located between the first magnetic suspension bearing 30 and the second magnetic suspension bearing 40 . In this way, during the normal operation of the compressor, the first magnetic suspension bearing 30 and the bearing structure 100 play a role in radially positioning the crankshaft 20, and the second magnetic suspension bearing 40 plays a role in positioning the crankshaft 20 in the axial direction, thereby ensuring that the crankshaft 20 is There is no displacement or play in the radial and axial directions during the rotation.

[0057] From the above description, it can be seen that the above-mentioned e...

Abstract

The invention provides a compressor, a compressor parallel system and a multi-online heat exchange system. The compressor includes a casing and a crankshaft arranged in the shell and also includes a first magnetic suspension bearing arranged in the casing and a second magnetic suspension bearing arranged in the casing, wherein the first magnetic suspension bearing and the second magnetic suspension bearing are respectively arranged at both ends of the crankshaft. The problems that the crankshaft is easy to wear and easily produces noise when the compressor runs at high speed in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor, a compressor parallel system and a multi-connection heat exchange system. Background technique [0002] In the prior art, the crankshaft of the compressor is connected to the housing by conventional bearings. Therefore, during the operation of the compressor, mechanical wear will occur between the crankshaft and the conventional bearing, which not only affects the working efficiency of the compressor, shortens the service life of the crankshaft or the conventional bearing, and reduces the operating reliability of the compressor, but also causes The compressor generates noise or vibration during operation, resulting in poor user experience. Contents of the invention [0003] The main purpose of the present invention is to provide a compressor, a compressor parallel system and a multi-connection heat exchange system to solve the problems in the prior art that t...
