Miniature automatic compensation buffer

AC0806、1005、1008、1210

1. Small size, compact structure, suitable for narrow space

2. Non detachable, high safety performance

3. External pressure cylinder full thread, flexible installation and adjustment

4. The load can not directly act on the end face, which will easily cause the end face deformation and affect the stroke recovery

Reaction muffler can be divided into five basic types: expansion chamber muffler, resonance muffler manufacturing equipment muffler, interference muffler, loss muffler and Venturi muffler.

Sound elimination principle: first, the muffler of expansion chamber will reflect the sound wave propagating along the pipeline to the direction of echo source by using the mutation of pipe cutting surface, that is, the change of acoustic impedance; secondly, by using the length of expansion chamber and inner sleeve, the forward propagating wave is out of phase with the acoustic wave reflected from different interfaces of the pipe by 180 degrees, so that their amplitude is the same, the phase is opposite, and they interfere with each other, so as to achieve the most ideal sound elimination effect Fruit.

Resonance mufflers are usually used to eliminate low frequency (below 350 Hz) noise transmitted by pipes. The noise elimination principle of the interference muffler is enough to divide the sound wave into two paths. A row of straight pipes are installed on the automobile muffler manufacturer to make the length of the pipe twice that of the straight pipe. The length of the pipe is equal to the wavelength of the sound wave to be eliminated, so the length of the straight pipe is half the wavelength. In this way, when the sound wave passes through two different length paths, two kinds of acoustic waves with equal amplitude and opposite displacement will be produced at the junction of the pipe and the straight pipe, which will interfere with each other and reduce the noise.
