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] Such as figure 1 , figure 2 with 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 a...

Abstract

The invention provides an adjusting structure of a centrifugal compressor and a centrifugal compressor. The adjusting structure of the centrifugal compressor is used for adjusting the width of a diffusion outlet of an impeller of the centrifugal compressor. The centrifugal compressor comprises a box body, and the diffusion outlet is commonly formed by a support fixedly connected with the box body, and a mounting plate. The adjusting structure comprises a driving device, a driving ring, a transmission device and an adjustable device. The driving ring is respectively connected with the driving device and the transmission device. The adjustable device is connected with the transmission device and shields the diffusion outlet. The driving ring is in a ring shape and is arranged on the support in a sleeved mode. The driving ring is provided with a slot matched with the transmission device. The driving device drives the driving ring to conduct relative rotation movement coaxial with the support. The driving ring drives the adjustable device to move through the transmission device and used for changing the shielding range of the adjustable device, and therefore the width of the diffusion outlet is adjusted. Design in reasonable, the structure is independent, installation is easy, the width of the diffusion outlet of the impeller of the centrifugal compressor is accurately adjusted, and refrigerant gas can be protected against backflow.

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.
