Problems solved by technology

If the intake pressure is reduced, the air consumption is reduced, and the exhaust speed is slowed down, although the noise can be reduced, the power of the air motor will not meet the requirements for matching the motor. Reduce the power loss of the air motor

Abstract

The invention discloses a noise elimination device for a pneumatic motor. An airflow rotating chamber is arranged between an air inlet and an air outlet, a baffle is arranged inside the airflow rotating chamber, the airflow rotating chamber is divided into an airflow compression cavity and an airflow noise elimination chamber through the baffle, a circular noise elimination body is assembled in the airflow noise elimination chamber, a plurality of layers of circular grooves are arranged on the outside circular surface of the circular noise elimination body, one or more guide holes are arranged in the circular grooves, a plurality of air vents are arranged on the baffle and correspond to groove ports of the circular grooves, an airflow convection chamber is formed between the circular grooves and the inner wall of a pipe body, and an airflow overlapping cover chamber between an inner side end face of the circular noise elimination body and the baffle. According to the device, a modularization modular design is adopted, so that the impedance matching speed decreasing ratio for noise elimination can be adjusted, the rotating direction of the airflow can be changed greatly, the airflow is compressed and be crossed into a multi-angle impact reflection overlapping cover, the discharging speed and the noise are reduced, and the best energy conservation and noise reduction effect is achieved.

Description

technical field [0001] The invention relates to the field of air motors, in particular to a noise reduction device for air motors. Background technique [0002] Mine air motor is a new type of drainage equipment with air (pneumatic) motor as the coaxial prime mover. It is not restricted by power supply, humidity, dust and other conditions. Especially in places where explosion-proof is required, electric submersible motors are irreplaceable in safety. And reliability, it is absolutely safe and reliable to use in industrial and mining operation surfaces containing gas and coal dust, as well as other flammable, explosive, vibration, high temperature... harsh working conditions. [0003] But for air motors, the exhaust noise is almost always between 115dB(A) and 124dB(A). Except for the jet noise of aircraft at 140dB(A), the noise of air motors can be regarded as the leader. Therefore, some people in foreign countries list air motor machinery as the third noise machinery. Air...
