Embodiment 1
[0044] This embodiment describes the screw rotor of the present invention in detail.
[0045] The screw rotor of this embodiment includes a first-stage rotor, a second-stage rotor and a connecting section 100, such as figure 1 shown. Preferably, the connecting section 100 is located between the first-stage rotor and the second-stage rotor, and the first-stage rotor, the connecting section 100 and the second-stage rotor are of an integrated structure, such as figure 1 shown. The first-stage rotor in this embodiment may also be called a low-pressure stage rotor, and the second-stage rotor may also be called a high-pressure stage rotor.
[0046] In the screw rotor of this embodiment, the connecting section 100 is located between the first-stage rotor and the second-stage rotor, so that the screw rotor can form two pairs of rotors, thereby realizing two-stage compression; on the other hand, compared with the prior art Two-stage screw rotor, in this embodiment, the first-stage r...
Embodiment 2
[0060] This embodiment describes the compressor of the present invention in detail.
[0061] The compressor of this embodiment includes a casing and a screw rotor, the screw rotor is arranged in the casing, and the screw rotor is the screw rotor of any one of the technical solutions in Embodiment 1. The rest of the structure of the compressor in this embodiment can be the same as that of the prior art, and will not be repeated here.
[0062] The compressor of this embodiment includes the screw rotor of any one of the technical solutions in Embodiment 1. Through the screw rotor of any one of the technical solutions of Embodiment 1, not only can the compressor achieve two-stage compression, but it also has a simplified structure. , High transmission efficiency and small transmission power loss can improve compressor efficiency.
[0063] According to a preferred embodiment, the casing includes a first-stage rotor casing and a second-stage rotor casing, the first-stage rotor casi...
Embodiment 3
[0066] This embodiment describes the air conditioner of the present invention in detail.
[0067] The air conditioner in this embodiment includes the compressor of any one of the technical solutions in Embodiment 2. The rest of the structure of the air conditioner in this embodiment can be the same as that of the prior art, and will not be repeated here.
[0068] Since the air conditioner in this embodiment includes the compressor of any one of the technical solutions in Embodiment 2, the performance of the air conditioner in this embodiment can be improved by using the compressor in any one of the technical solutions in Embodiment 2.

Abstract
The invention discloses a screw rotor, a compressor and an air conditioner, relates to the technical field of air conditioners, and solves the problems that in the prior art, a high-pressure-stage rotor and a low-pressure-stage rotor of a two-stage double-screw compressor need to be connected through a coupler, so that transmission power loss is caused, and the efficiency of the compressor is reduced. The screw rotor comprises a first-stage rotor, a second-stage rotor and a connecting section, the connecting section is located between the first-stage rotor and the second-stage rotor, and the first-stage rotor, the connecting section and the second-stage rotor are of an integrated structure. The first-stage rotor and the second-stage rotor of the screw rotor are connected without a coupler, so that the structure of the screw rotor can be simplified, the transmission efficiency is improved, the transmission power loss is reduced, the loss is reduced, and the efficiency of a compressor can be improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a screw rotor, a compressor including the screw rotor and an air conditioner including the compressor. Background technique [0002] Compared with the one-stage screw compressor, the two-stage twin-screw compressor has the advantages of large pressure ratio and wide range of working conditions, so the two-stage screw compressor is the development direction of the compressor in the future. The current two-stage twin-screw compressor includes two pairs of separately processed rotors, wherein the drive shafts of the two-stage rotors are connected by couplings, and the two-stage rotors are individually equipped with bearings to carry axial and radial forces. Due to the above structural limitations, the two-stage twin-screw compressor has at least the following defects compared with the single-stage compressor: (1) The two pairs of rotors need to be processed separately, and ...
