Problems solved by technology

[0004] The resistant muffler is composed of a tube and a chamber with a sudden change interface, but the internal structure of the existing resistant muffler is fixed, and the cross-sectional area of ​​the pipe cavity cannot be changed, which means that its ability to reduce noise is limited. Limited, if there is no good noise reduction during construction, the noise will be amplified several times in an open environment, which will inevitably affect the surrounding environment

Abstract

The invention discloses a small-sized air compressor for environmental protection construction and its use method, which belongs to the field of air compressors. It uses the principle of aerodynamics to make two pneumatic parts approach each other under the action of air flow, so that the front and rear sections There is a large mutation in the area to improve the noise reduction effect, and the greater the airflow intensity, the greater the change in the cross-sectional area of ​​the aerodynamically deformable shell, and the better the noise reduction effect. The annular cavity inside the aerodynamic weakening part is used to weaken the airflow The flow rate, and two air inlet holes and one air outlet hole can allow the airflow to form convection, which has a certain noise reduction effect. The porous airflow disturbance ball is used to further weaken the airflow velocity, and finally the airflow passes through the airflow distribution pipes with different inner diameters. Ejection, once again uses the sudden change of the cross-sectional area to reduce noise, and further improves the noise reduction effect. Compared with the existing technology, it realizes the dynamic change of the cross-sectional area, and strengthens the effect of using the sudden change of the cross-sectional area to reduce noise.

Description

technical field [0001] The invention relates to the field of air compressors, and more specifically relates to a small air compressor for environmental protection construction and its usage method. Background technique [0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane or rotary screw. Air compressor is a general-purpose mechanical product with a large quantity and a wide range. It is widely used in machinery, mining, chemical industry, construction and other departments. The noise level it produces is high and has a great impact. For various manufacturing departments, solving the noise problem of air compressors can further improve the quality of products. Solving the noise of air compressors can greatly help improve people's livelihood and environmental pollution. Air compressor noise pollution needs reasonable control. [0003] The main noise...
