Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0023] After further research on compressors with rotors arranged horizontally in the prior art, such as figure 2 As shown, when the slide valve 2 is on the top of the male rotor 4 and the female rotor 5, this arrangement causes the compressor center of gravity to be above the center line of the rotor, and the center of gravity is at the center of the male rotor 4 and the female rotor 5, which deviates from the male rotor 4's center of rotation position. Such as image 3 As shown, when the slide valve 2 is located at the bottom of the male rotor 4 and the female rotor 5, this arrangement can...

Abstract

The present application provides a screw compressor and an air conditioning unit. The screw compressor includes a shell and a male rotor and a female rotor arranged in the shell. The male rotor and the female rotor are arranged in a vertical direction and located in a vertical direction where the gravity center of the shell is located. In the technical solution of the present invention, since themale rotor and the female rotor are arranged in the vertical direction and located in the vertical direction where the gravity center of the shell is located, the rotation centers of the male rotor and the female rotor are also located in the vertical direction where the gravity center of the shell is located, then eccentric vibration is avoided, which is caused by the deviation of the rotation centers of the male rotor and the female rotor from the vertical direction where the gravity center of the shell is located, thereby the vibration of the compressor is reduced and the stability of the compressor in the operation process is ensured.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a screw compressor and an air conditioner unit. Background technique [0002] The screw compressor belongs to the volumetric refrigeration compressor. It uses a pair of intermeshing female and male rotors to make rotary motion in the body cavity, and periodically changes the volume between each pair of tooth slots of the rotor to complete suction, compression, and exhaust. process. [0003] Such as figure 1 As shown, the capacity adjustment slide valve is a common structure used to adjust the volumetric flow in screw compressors. A pair of male and female rotors arranged in a horizontal direction are arranged on the compressor housing 1. The slide valve 2 is assembled on the compressor housing. The slide valve 2 becomes a part of the compressor housing, located at the intersection of the rotor cavity, the slide valve 2 can move back and forth in a direction para...
