Problems solved by technology

However, since this turbocompressor needs to form a polytetrafluoroethylene layer or a fluoride layer on the entire surface of the sliding part that is in contact with the sliding part, this will not only make the processing of the part more complicated, but also make the surface of the entire part more complicated. Processing also increases production costs substantially

Embodiment Construction

[0026] like Figure 9 , Figure 10 As shown, the compression mechanism of the asymmetrical turbo compressor includes a fixed scroll 40 connected to the bracket 1 and having a spiral curved scroll piece 41, located between the fixed scroll 40 and the bracket 1 and connected to the fixed scroll 40 The movable scroll 50 connected and movable, the scroll piece 51 of the movable scroll 50 and the scroll piece 41 of the fixed scroll 40 are engaged with each other. A pressure chamber P can be formed between the scroll plate 41 of the fixed scroll 40 and the scroll plate 51 of the movable scroll 50, and in the state where the fixed scroll scroll plate 41 and the movable scroll plate 51 are engaged, the two turbines The tip angles of the scroll discs differ by 180° and are formed along the helical line. An Oldham coupling ring 30 which can prevent the movable scroll 50 from rotating is installed between the support 1 and the movable scroll 50 . The Oldham coupling ring 30 has the fi...

Abstract

A silencing unit of asymmetrical turbo compressor which is composed of movable vortex disk installed to supporter for transmitting drive force, static vortex disk, and compressing chamber with autorotation prevention provided by cross shift coupling ring features that it can make the key of said cross shift coupling ring and its key slot in elastic contact, so reducing the contact noise.

Description

technical field [0001] The invention relates to a noise reduction device for an asymmetric turbo compressor. Background technique [0002] figure 1 It is a sectional view of the compression mechanism of a common asymmetric turbo compressor. like figure 1 As shown, the bracket 1 in the compression mechanism of the turbo compressor is connected to the fixed scroll 10, and the movable scroll 20 that can move in a plane is connected between the fixed scroll 10 and the bracket 1, and the movable scroll 20 is inserted into the bracket The eccentric part 2a of the rotating shaft 2 on the upper part is connected, and the rotating shaft 2 is connected with the rotating mechanism. In addition, an Oldham coupling ring 30 is connected between the support 1 and the movable scroll 20 , and its function is to prevent the movable scroll 20 from rotating. [0003] figure 2 for figure 1 An exploded schematic diagram of the main components of the compression mechanism of the turbo compr...
