Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the adjustment structure of the centrifugal compressor and the centrifugal compressor of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] like figure 1 , figure 2 and Figure 8 As shown, an adjustment structure of a centrifugal compressor is used to adjust the width of the diffuser outlet 8 of the impeller of the centrifugal compressor. The centrifugal compressor includes a casing 6, and the diffuser outlet 8 is fixedly connected with the casing 6. The support 5 and the mounting plate 7 are jointly formed. The adjustment structure of the centrifugal compressor includes a driving device 1, a driving ring 2, a transmission device 3 and a...

Abstract

Disclosed are a centrifugal compressor adjustment structure and a centrifugal compressor. The adjustment structure is used for adjusting the width of a diffuser outlet of an impeller of a centrifugal compressor. The centrifugal compressor comprises a box body (6). A diffuser outlet (8) is formed together by a support seat (5) and a mounting plate (7) fixedly connected to the box body (6). The adjustment structure comprises a drive device (1), a drive ring (2), a transmission device (3) and an adjuster (4); wherein the drive ring (2) is connected to the drive device (1) and the transmission device (3), respectively; the adjuster (4) is connected to the transmission device (3), and blocks the diffuser outlet (8); the drive ring (2) is circular ring shaped and is sheathed on the support seat (5), and a slot hole (9) fitting with the transmission device (3) is provided on the drive ring (2); the drive device (1) drives the drive ring (2) to make a relative rotational movement coaxial with the support seat (5); and the drive ring (2) drives the movement of the adjuster (4) via the transmission device (3), changing the blocking range of the adjuster (4), thereby accurately adjusting the width of the diffuser outlet of the impeller of the centrifugal compressor, and enabling back-flow of refrigerant gas to be prevented.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an adjustment structure of a centrifugal compressor and the centrifugal compressor. Background technique [0002] With the continuous advancement of science and technology, the application of centrifugal compressors in the production of household appliances is becoming more and more extensive. [0003] At present, a regulator is installed at the outlet of the impeller of the centrifugal compressor, so that an adjustable section of width is formed at the outlet of the impeller, and the outlet width of the impeller is adjusted according to the operating conditions of the unit. Existing regulators for centrifugal compressors are all linked with the impeller regulating mechanism, the control is not independent, the structure is not independent, so the control is not accurate enough, and the refrigerant gas cannot be prevented from flowing back. Contents of the inventio...
