Abstract

The invention discloses a broad-spectrum-filtration vibration-absorbing silencer of a hydraulic system, which comprises an oil opening, a vibration absorber shell, upper and lower partition boards, resonance plate springs and damping holes. The broad-spectrum-filtration vibration-absorbing silencer of the hydraulic system has a structure that: the expandable cavity type vibration absorber shell is fixed with the upper and lower partition boards through welding; each partition board is provided with a plurality of triangular holes; the insides of the holes are sealed and fixedly connected with the resonance plate springs through flexible bodies; and the resonance plate springs hold mass bodies of different masses respectively and the damping holes are drilled in the resonance plate springs, so that the resonance plate springs holding different mass bodies and the damping holes form 'quality + spring + damping' lumped parameter type coupling spring vibration systems and the coupling spring vibration systems have respective natural frequencies. The structure can meet working condition requirements of hydraulic oil such as high pressure, stable high flow, low compressibility, corrosion resistance and the like and has better broad-spectrum filtration effects in both low and mediate frequency ranges.

Description

technical field [0001] The patent of the present invention relates to a vibration reduction and noise reduction equipment in the hydraulic system process. The equipment has resonant leaf springs of various frequencies, and uses the coupling vibration of liquid and solid to eliminate vibration energy of different frequencies in the hydraulic system, thereby reducing vibration. The effect of vibration and noise reduction. Background technique [0002] Hydraulic system is the core technology of various mechanical equipment. With the development of hydraulic technology in the direction of high speed, high pressure and high power, the vibration and noise in the hydraulic system have become one of the important factors hindering the progress of hydraulic technology and the safety of life and property. [0003] The vibration and noise of the hydraulic system mainly come from two aspects: mechanical vibration and noise and fluid vibration and noise. In addition to the hydraulic eq...
