Embodiment 1

[0017] As attached to the manual figure 1 As shown, a five-stage scroll compressor mainly includes: a movable scroll (B), a fixed scroll (A), an Oldham ring (C), and an eccentric shaft (D). It is characterized in that the structure of the movable scroll (B) and the fixed scroll (A) is as shown in the drawings of the specification, and the height of the ordinary single-stage scroll is h1, and the height of the first-stage compression (1) in Fig. 4 is also is h1, the second stage compression (2) height is h2 (h2<h1), the third stage compression (3) height h3 (h3<h2), the fourth stage compression (4) height h4 (h4<h3), the first Five-stage compression (5) height h5 (h5<h4), movable scroll (B) and fixed scroll (A) are meshed with each other, and the working principle is the same as that of single-stage compressor: the scroll profile parameters are the same, After the movable scroll (B) and the fixed scroll (A) with a phase difference of π and a distance r between the center of th...

Abstract

The invention relates to a five-stage scroll compressor, and belongs to the technical field of design theories of mechanical equipment. The five-stage scroll compressor mainly comprises a movable scroll, a fixed scroll, a cross ring and an eccentric shaft. The movable scroll and the fixed scroll which have the same scroll mold line parameter, a phase difference pi and a base circle center distance r are assembled to form a plurality of pairs of closed five-stage crescent volume cavities, and the number of the closed volume cavities is correspondingly increased or reduced when the center of the movable scroll (the base circle center) moves around the center of the fixed scroll (the base circle center) along a circular orbit with the radius of r, so that the aim of inhaling, compressing and exhausting gas is fulfilled. First-stage compression, second-stage compression, third-stage compression, fourth-stage compression and fifth-stage compression are performed simultaneously, and low-pressure gas enters a gas inhaling cavity from gaps at the periphery of the movable scroll and the fixed scroll, and is compressed and then discharged from an exhaust orifice in the center of the fixed scroll. The five-stage scroll compressor has the characteristics of simple structure, small volume, high volume utilization rate and compression ratio, low noise and the like, moves stably, and can be widely applied to air-conditioning equipment and refrigerating units.

Description

technical field [0001] The invention specifically relates to a five-stage scroll compressor, which belongs to the technical field of mechanical equipment design theory. Background technique [0002] Scroll compressor is a precision machine used for compression and refrigeration. It has a series of advantages such as simple and compact structure, high efficiency and energy saving, low vibration and low noise, and high reliability, which makes the application of scroll compressor in the field of refrigeration and air conditioning very interesting. rapid development. Today, scroll compressors are widely used in small and medium-sized air conditioning and refrigeration units. However, the existing technologies are mainly monopolized by the United States and Japan. Therefore, it is imperative to develop scroll compressors with my country's independent intellectual property rights. [0003] Although the traditional single-stage scroll compressor has the advantages of fewer compo...
