Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0020] In the screw compressor, the exhaust pipe structure is used in the exhaust oil separation stage. The airflow in the exhaust pipe is high-temperature, high-pressure and high-speed flow, which produces a large airflow noise, which is transmitted through the exhaust pipe wall. The exhaust flow rate is constant. Under normal circumstances, the inner diameter of the exhaust pipe can be determined, and in the common selection of exhaust pipes, the wall thickness of the seamless steel pipe is almost a fixed value, and the wall thickness of the seamless steel pipe material that is often forced to be used is only sufficient for strength, but for Blocking exhaust noise isn't enough.

[0021] Aiming at the above-mentioned objective technical difficulty and technical problems that cannot be...

Abstract

The invention discloses an exhaust pipe with an effective noise reducing function and a compressor. The exhaust pipe comprises a main body and an outer sleeve. An exhaust channel is arranged in the main body. The outer sleeve sleeves the main body, the outer sleeve and the main body are in sealed connection, and sealed space is formed between the outer sleeve and the main body. According to the exhaust pipe with the effective noise reducing function and the compressor, the problem that in the prior art, an exhaust pipe of a compressor is small in obstructing force on air flow noise in the pipe, and consequently the transferring noise is large is effectively solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an exhaust pipe and a compressor that can effectively reduce noise. Background technique [0002] In the prior art, the basic working principle of the screw compressor is the process of discharging the inhaled working fluid from the compressor after being meshed and compressed by the screw rotors. In the exhaust stage, the high-temperature and high-pressure gaseous working medium hits the exhaust pipe and other parts at high speed, resulting in a huge exhaust noise. [0003] Among the various existing solutions for reducing exhaust noise, seamless steel pipes with a thicker wall thickness are used as raw materials to process exhaust pipes as large as possible, which can alleviate part of the transmission of exhaust noise. However, limited by the inner diameter of the required exhaust pipe and the specifications of the national standard seamless steel pipe material, the thick...
