Introduction to noise in hydraulic systems
Since the vibration and noise of the hydraulic system are inevitable, and in recent years, with the development of hydraulic technology to the direction of high speed, high pressure and high power, the noise of the hydraulic system has become increasingly serious, and it has become a factor hindering the further development of hydraulic technology. More than 70dB becomes noise, which makes people feel very uncomfortable and even irritating. Noise has become more and more important as pollution. Therefore, it is of positive and far-reaching significance to study and analyze the mechanism of hydraulic noise and vibration, thereby reducing and reducing vibration and noise, and improving the performance of the hydraulic system.
