What are the noise elimination methods for high temperature fans and centrifugal fans

The noise generated by high-temperature centrifugal fans is usually caused by friction and barriers between aerodynamics and the environment. In other words, if the circumferential speed of the centrifugal fan impeller of a high-temperature fan is too high, the impact on ambient air noise will be more significant, and the noise ratio of the impeller will increase. If the noise of the high-temperature fan and the centrifugal fan is too large, it will have a significant negative impact. Therefore, we must take measures to solve this problem.
With the wind pressure and air volume unchanged, first of all, pay attention to the speed and direction of the air flow. For example, we can make the changes in the centrifugal fan end of the high-temperature fan as obvious as possible. Of course, the correct and reasonable selection of centrifugal fans for high-temperature fans is also a very important issue. This must be considered in conjunction with our actual use. In addition, you can also choose to connect a centrifugal fan with a high-temperature fan directly to the motor to effectively reduce its noise. If indirect transmission is to be used, it is necessary to use a gapless trapezoidal belt for connection. In addition, it is also a very effective method to design the inlet and outlet of the high-temperature fan and centrifugal fan in a straight line to avoid sharp turns. In this case, it can also reduce the noise generated by circulating air during the intake and outlet of the high-temperature fan and centrifugal fan. Of course, we can also choose to use soundproofing materials to reduce noise levels. However, in practical work, centrifugal fans equipped with high-temperature fans are affected by various factors and cannot directly reduce noise from the perspective of students. Therefore, in many cases, it is necessary to use silencers and soundproofing materials to reduce the noise of high-temperature and centrifugal fans.
