Embodiment 1

[0039] Such as image 3 As shown, the present invention provides a kind of liquid level regulating device, comprises regulating device body 1, and regulating device body 1 is arranged on the bottom of compressor casing 2, has volume chamber in regulating device body 1, volume chamber and compressor casing The inner cavities of the body 2 are communicated, and at least part of the liquid medium in the compressor housing 2 is introduced into the volume cavity so that the connection between the wiring device 3 on the compressor housing 2 and the liquid medium 100 in the compressor housing 2 The distance between the liquid levels 200 increases. The present invention fills part of the mixed liquid of lubricating oil and refrigerant into the regulator body 1 at the bottom of the compressor housing 2, thereby lowering the oil level 200, which can effectively solve the problem that the terminals on the compressor housing 2 are close to the oil level 200. The problem is to increase th...

Embodiment 2

[0049] The difference between embodiment 2 and embodiment 1 is that the liquid level adjustment device is arranged at the bottom of the shell body 21 and the bottom of the end cover 22, and the adjustment device body 1 and the shell body 21, and the adjustment device body 1 and the end cover 22 are integrally formed. , this embodiment 2 also has two optional design schemes, the first one, such as Figure 7-Figure 9 As shown, the adjusting device body 1 is arranged on the bottom of the shell body 21 and the bottom of the two end covers 22, that is, the bottom of the shell body 21 and the two end covers 22 protrude downwards, and are spliced ​​together to form the adjusting device body 1 and the end covers The downward protruding parts on 22 form the side walls at both ends of the tank structure, and the downward protruding parts of the bottom of the shell body 22 form both side walls and the bottom plate of the tank structure, through the protruding parts of the shell body 21 an...

Abstract

The invention provides a liquid level adjusting device, a compressor shell and a compressor and relates to the technical field of compressors. The liquid level adjusting device, the compressor shell and the compressor solve the technical problem that the insulation resistance can be easily reduced rapidly due to the fact that a terminal post of the compressor is too close to the liquid level of aliquid medium. The liquid level adjusting device comprises an adjusting device body, wherein the adjusting device body is arranged at the bottom of the compressor shell and is internally provided withan accommodating cavity communicating with an inner cavity of the compressor shell. The liquid medium in the compressor shell is at least partially introduced into the accommodating cavity so as to increase the distance between a wiring device on the compressor shell and the liquid level of the liquid medium in the compressor shell. The compressor is a vortex compressor which is easy to obtain, not changed in installation height and capable of reducing the oil liquid level. The shell protrudes downwards, so that some of the liquid medium can be filled into the protruding portion of the shell,the problem that the insulation resistance of the compressor is rapidly reduced under a static state is avoided, and electrical use requirements are met.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a liquid level regulating device, a compressor casing and a compressor. Background technique [0002] The terminals of most existing horizontal scroll compressors are arranged horizontally outside the casing of the compressor. This arrangement of terminals makes it very convenient to connect the compressors to the air conditioning system. [0003] The applicant finds that there are at least the following technical problems in the prior art: [0004] Such as figure 1 As shown, since the mixture of lubricating oil and refrigerant in the compressor is located at the bottom of the inner cavity of the compressor housing, and the liquid mixture has a certain depth, the arrangement of the terminals horizontally in the middle of the compressor housing may easily lead to The liquid surface of the lubricating oil and refrigerant mixture touches the terminal or is too close to the ter...
