Problems solved by technology

[0010] However, when the compressor operates without refrigerant or when the auxiliary valve (suction valve) is closed, the refrigerant existing in the suction pressure chamber will be sucked into the compression chamber and discharged into the discharge chamber; therefore, not only the suction pressure chamber will become a vacuum state, Moreover, the compression chamber will gradually become a vacuum state
Such abnormal operation lasts for a period of time, which will increase the vacuum in the suction chamber and compression chamber, resulting in frictional damage to the end of the blade due to vacuum compression, or thermal damage to the compression mechanism, which will eventually lead to performance degradation and adverse consequences of the compressor.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the implementation of the present invention is described as follows:

[0026] figure 1 The description in has been described in detail in "Background Technology" and is omitted here.

[0027] exist figure 2 , image 3 Among them, the upper bracket (2) is fixed on the casing (1), and the fixed scroll (10) with a high vacuum prevention device (100) is fixed on the convex edge of the upper bracket (2), together with the fixed scroll (10) The movable scroll (6) forming a plurality of compression chambers is connected with the drive shaft (5) of the electric motor as a whole, and the movable scroll (6) is arranged on the upper moving frame (2) and is tightly attached to each other. That is, the movable scroll (6) is embedded in the internal space formed by the fixed scroll (10) and the upper support (2), and rotates with the rotation of the drive shaft.

[0028] On the upper side of the above-mentioned fixed scroll, a high...

Abstract

A vacuum compression preventer for vortex compressor composed of static and moving vortex disks is disclosed to prevent the friction damage of the front end of compressing blade. Said preventer features that a valve piece with spring is arranged in a valve chamber under static disk. When the pressure in compressing chamber changes, it can slide up and down to open or close the inlet and outlet ofcompressing chamber. It can also prevent the heat generation of parts and valve noise.

Description

technical field [0001] The invention belongs to scroll compressors, in particular to a vacuum compression preventing device for scroll compressors. Background technique [0002] Currently, known scroll compressors (see figure 1 As shown), it converts mechanical energy into compression energy of compressive fluid. Compressors with such functions are roughly divided into piston type, scroll type, centrifugal type and screw type. [0003] Among them, the above-mentioned scroll compressor is different from a reciprocating compressor using a linear motion of a piston, and similar to a centrifugal or screw compressor, uses a rotating body to suck in and compress and discharge gas. The above-mentioned scroll compressors are classified into low-pressure scroll compressors or high-pressure scroll compressors depending on whether the casing is filled with suction gas or discharge gas. [0004] The above-mentioned low-pressure scroll compressor is as figure 1 As...
