In some giant buildings, the air conditioning in the hall is provided by the 6FWB unit fixed in the basement. The vibration of the unit is transmitted to the ground hall through the bridge connecting the rubber hose pipes, and the noise value is up to 45dB. In such an environment, people always feel uncomfortable. After changing the design, the connecting pipes are connected in series Sandblasting hose Not only the noise generated by the unit vibration is absorbed, but also the noise generated by the fluid pulsation in the pipeline system is absorbed. At this time, the noise value in the ground hall is only 33dB, greatly improving the environment in the hall.

Sandblasting hose Although it has good flexibility and strong fatigue resistance, it also needs to be treasured, so we can't mess around. Sand blasting hose can absorb vibration, which can not only improve the fatigue damage ability of the system, but also reduce noise.
