The manufacturer of ACM series grinding system tells you that for powder machinery, when fluid flows through the valve body, if the pressure difference between the front and rear is too large, it will cause cavitation on the valve core, valve seat and other parts, causing the fluid to produce noise and flow capacity. If the value is large, it is necessary to re-select a regulating valve with a suitable flow capacity value to overcome the noise caused by the mechanical working at a small opening. The following ACM series grinding system manufacturers will introduce some noise processing methods:

1. Adopt sound-absorbing material method: This is also a common and most effective sound path processing method. The manufacturer of ACM series grinding system tells you that noise sources and powder machinery pipelines can be covered with sound-absorbing materials. It must be pointed out that since noise will travel long distances through fluid flow, where the sound-absorbing material is packaged and where thick-walled pipes are used, the effectiveness of noise elimination will end.
2. Elimination of resonance noise method: The manufacturer of ACM series grinding system tells you that only when the powder machinery resonates, the energy is superimposed to produce a strong noise of more than 100 decibels. Some are characterized by strong vibration, low noise, and weak vibration. The noise is very loud, and some vibrations and noises are loud. Obviously, the noise will disappear naturally when the resonance is eliminated.
3. The method of series silencer: The manufacturer of ACM series grinding system tells you that it is suitable for the silencer of aerodynamic noise. It can effectively eliminate the noise inside the fluid and suppress the noise level transmitted to the solid boundary layer. The manufacturer of ACM series grinding system tells you that this method is most effective and economical for places where the mass flow rate is high or the pressure drop ratio before and after the valve is high. The use of absorbing tandem silencers can greatly reduce noise.
4. Elimination of cavitation noise: ACM series grinding system manufacturers tell you that cavitation is the main source of fluid dynamic noise. During cavitation, the bubble bursts and produces high-speed impact, which causes strong turbulence locally and produces cavitation noise. This kind of noise has a wide frequency range and produces a rattling sound, similar to the sound made by sand and gravel in a fluid. Eliminating and reducing cavitation is an effective way to eliminate and reduce noise.
The manufacturer of ACM series grinding system tells you that for powder machinery, the best way to deal with noise is to control the noise source to fundamentally eliminate or reduce the noise. This requires us to buy low-noise pumps and low-noise machinery, and if When the noise is not too great, choose a low-noise sleeve valve, which can reduce the noise by 20 decibels, which is also a relatively economical noise adjustment method.
