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

1. Use sound-proof material method: ACM series grinding system manufacturer tells you to wrap noise source and powder equipment pipeline with sound-proof material. Noise will spread over long distances through the flow of liquid, so wherever the sound insulation material is wrapped, the thick-walled pipe will go wherever it goes, which can reasonably remove the noise.
2. Elimination of resonance and noise: ACM series grinding system manufacturers tell you that only when the powder equipment is in resonance, can the energy accumulate and cause a strong noise of more than 100 decibels, and some are characterized by strong vibration and low noise. Clear the resonance , The noise naturally fades.
3. Serial muffler method: This method is mainly used as aerodynamic noise muffler, to remove the noise inside the liquid reasonably and reduce the noise level transmitted to the solid boundary layer. The manufacturer of ACM series grinding system tells you that this method is reasonable and economical for places where the mass flow rate is high or the pressure drop ratio before and after the valve is high. The application of absorbing series muffler can greatly reduce noise.
4. Method of eliminating cavitation noise: ACM series grinding system manufacturers tell you that cavitation is the main source of fluid machinery noise. During cavitation, the bubbles crack and cause high-speed impact, causing strong seepage in some parts, causing cavitation noise. This type of noise has a wide frequency range, resulting in a rattling sound, similar to the sound emitted by sand in a liquid. Eliminating and reducing cavitation is a reasonable method to eliminate and reduce noise.
The manufacturer of ACM series grinding system tells you that for powder equipment, the best way to deal with noise is to control the noise source, remove or reduce the noise from the source, which requires us to buy low-noise pumps and low-noise equipment. When it is not very large, using a low-noise sleeve valve can reduce the noise by 20 decibels, which is also a more economical noise adjustment method.
