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

By reducing the exhaust pressure, increasing the displacement and reducing the rotational speed, the principle of decompression and expansion can be effectively understood, that is, the stainless steel quick connector can reduce the displacement, reduce the displacement and reduce the displacement. For block jet noise, it can be divided into pressure and velocity. When the pressure changes, the sound level a seems to be only proportional to the logarithm of the pressure difference at a certain nozzle. The pressure difference p-po is doubled and the a sound level is reduced by 69 dB. Therefore, the pressure can be gradually reduced to 1.89 critical pressure according to the exhaust volume, so as to achieve the purpose of reducing noise.

According to the fact that the sound power of the exhaust pipe noise is proportional to the eighth power of the exhaust pipe speed, if the exhaust pipe speed is reduced by one time when the diameter of the exhaust pipe is the same, the noise of the blocked exhaust pipe of the engine muffler can be reduced by 24dB. Therefore, the noise of the exhaust pipe can be reduced by reducing the pressure of the exhaust pipe or reducing the speed of the exhaust pipe.
