1. Special internal pressure cylinder combination adjustment structure, bearing strong impact force

2. There is a buffer zone of 3 mm at the end of the product

3. In order to ensure the safety of use, it is necessary to determine the bearing capacity of the carrier before use

4. The fixing methods can be divided into two types: the rubber sheet fixing or the flange fixing

5. Be sure to stop 2-3mm before the stroke to avoid damage to internal parts due to excessive load

Muffler is an effective device to control the diffusion of aerodynamic noise. It can be seen as an integral part of the piping system. The internal acoustic treatment can reduce the noise generation and transmission without affecting the air flow. The noise attenuation can reach 10-40 dB (a) and the loudness can be reduced by 50% - 93% by installing mufflers at the air flow intersection at the inlet and outlet of pneumatic mechanical equipment. The soft connection effect of subjective muffler is obvious.

According to the principle of noise elimination, mufflers can be divided into resistive muffler, reactive muffler, microporous muffler and resistive composite muffler.

The resistive muffler has the characteristics of absorbing medium and high frequency sound and simple manufacturing.

The invention has the characteristics of strong pertinence, good absorption effect of medium and low frequency, and no need of sound absorption material.

Microporous muffler is a new type of muffler, which has the performance of middle low frequency broadband noise elimination. It is mainly used for high pressure and high temperature exhaust and venting of power plant.

Impedance composite muffler has the characteristics of wide frequency band. It is mainly used for silencing broadband noise with high sound level and low intermediate frequency.
