With the development of hydraulic press machine technology, people are paying more and more attention to its noise. Serious noise pollution affects the public's health. In order to effectively reduce the noise generated by the hydraulic press, a muffler is generally installed at the exhaust port of the reversing valve. This measure indeed has the effect of reducing noise. Does anyone know anything about the types of mufflers used?

                                         
The reason why the muffler can reduce the noise of the hydraulic press is to increase the vibration damping or increase the cross-sectional area of the exhaust pipe, thereby reducing the exhaust speed and power of the equipment. There are three main types of mufflers used to assist in reducing noise in hydraulic press machines, namely absorption type, expansion interference type and expansion interference absorption type. The systems used are also different.
Absorption mufflers simply use sound-absorbing materials to silence sound. They are not only compact in structure, but also have particularly good sound-absorbing effects on medium and high-frequency noise. Therefore, they can be applied to general pneumatic systems and hydraulic systems. The diameter of the expansion interference muffler is very large, so the cyclone can also reduce its speed after a series of functions inside, thus playing the role of silencing, but the structure is not compact enough. After merging the above two products, an expansion interference absorption muffler is formed, which is more effective in comparison.
