Description

Technical Field

[0002] An air compressor is a device used to compress air, and a large amount of heat and noise will be generated during its operation, such as the widely used screw compressor in air compressors. The screw compressor is composed of a pair of male and female rotors that are parallel to each other and meshed with each other, and the purpose of compressing air is achieved by the high-speed rotation of the male and female rotors. During the high-speed rotation of the male and female rotors, a large amount of heat will be generated. If it cannot be dissipated in time, the working efficiency of the screw compressor will be reduced, affecting the service life of the screw compressor; and noise will be generated, and it cannot be used in some noise-sensitive application scenarios.

Although it can effectively solve the above problems, in the specific implementation process of this prior art, the effect of reducing or eliminating noise is relatively limited.

[0028] For example, see Figures 1 to 3 The utility model provides a technical solution: a high-performance refrigeration compressor rotor seat, including an outer shell, an inner shell 8, and an end cover 5. The inner shell 8 is located inside the outer shell, and a cavity layer is formed between the inner shell 8 and the outer shell. The end cover 5 is installed on the outer shell.

[0029] A plurality of support baffles 6 are fixedly connected to the outer side wall of the inner shell 8, and the edge of the support baffle 6 away from the inner shell 8 is fixedly connected to the inner side wall of the outer shell, and each support baffle 6 divides the cavity layer into a plurality of liquid chambers 9. A through hole 7 is opened on each support baffle 6, and two adjacent liquid chambers 9 are connected to each other through the through hole 7.

[0030] Among them, each supporting baffle 6 is used to support and fix the inner shell 8 inside the outer shell. Each liquid cavity 9 is connected to each other through each through hole 7. The liquid cavity 9 is used to store or flow cooling liquid, and the cooling liquid is used to cool the equipment (the outer shell, the inner shell 8 and other parts). The liquid medium in the liquid cavity 9 can reduce the noise generated by the equipment.

[0031] The outer wall of the inner shell 8 and the inner wall of the outer shell are both wavy. A liquid outlet pipe 10 is fixedly connected to the outer shell, and the liquid outlet pipe 10 is communicated with the liquid cavity 9 inside the outer shell.

[0032] Among them, the inner wall of the outer shell and the outer wall of the inner shell 8 are both wavy. The wavy liquid cavity 9 can make the sound waves generated by the equipment during operation swirl in the wave peaks of the liquid cavity 9 and trap the sound waves in the wave peaks, thereby effectively weakening and eliminating the sound waves and achieving the purpose of reducing noise.

[0033] Specifically, the outer shell includes a first outer shell 1 and a second outer shell 2, one end of the second outer shell 2 is sealed and fixedly installed with one end of the first outer shell 1 through a plurality of bolts 4, and the other end of the second outer shell 2 is sealed and fixedly installed with an end cover 5 through a plurality of bolts 4.

[0034] Wherein, a sealing gasket is provided at the abutting portion between the second outer casing 2 and the first outer casing 1 to prevent the liquid medium from leaking out. A sealing gasket is provided at the abutting portion between the second outer casing 2 and the end cover 5 to prevent the liquid medium from leaking out.
