因为液压系统的振动和噪声本身不可避免，而且近几年，跟着液压技术向高速、高压和大功率方向的发展，液压系统的噪声也日趋严峻，并且成为妨碍液压技术进1步发展的因素，声音超过70dB便成为噪声，使人听起来极不惬意，甚至使人烦燥不安，噪声作为污染已经日益受到人们的正视。因此研究和分析液压噪声和振动的机理，从而减少与降低振动和噪声，并改善液压系统的机能，有着积极而深远的意义。 降低液压系统噪声的措施：
为减少噪声，必需对噪声源进行实际调查，丈量分析液压系统的声压级，进行频率分析，从而把握噪声源的大小及频率特性，采取相应办法，详细列举如下：
① 使用低噪声电机；并使用弹性联轴器，以减少该环节引起的振动和噪声；
② 在电念头，液压泵和液压阀的安装面上应设置防振胶垫；
③ 尽量用液压集成块代替管道，以减少振动；
④ 用蓄能器和橡胶软管减少由压力脉动引起的振动，蓄能器能吸收10 Hz以下的噪声，而高频噪声，用液压软管则十分有效；
⑤ 用带有吸声材料的隔声罩，将液压泵罩上也能有效地降低噪声；
⑥ 系统中应设置放气装置。

Dongguan, the hydraulic system supporting small hydraulic system custom hydraulic system works , hydraulic systems supporting manufacturers
Because of the hydraulic system vibration and noise itself is inevitable, but in recent years, with hydraulic technology to high-speed , high-pressure and high-power development direction of the hydraulic system noise are becoming increasingly severe , and impeded the further development of hydraulic technology factors , voice over 70dB noise has become , people do not sound very nice, even gives restlessness, noise pollution has increasingly being used as a front . Therefore, research and analysis of hydraulic noise and vibration mechanism , thereby reducing and reducing vibration and noise , and to improve the functioning of the hydraulic system , have a positive and far-reaching significance. Measures to reduce the noise of the hydraulic system :
To reduce noise , it is necessary for the actual investigation of noise sources , measuring the sound pressure level of the hydraulic system , frequency analysis to capture the size and frequency of the noise source characteristics , take appropriate measures , detailed below :
① the use of low-noise motor ; and use the flexible coupling to reduce the vibration and noise caused by links ;
② In the electric motor , hydraulic pump and hydraulic valve mounting surface should be set vibration pads ;
③ try to replace the pipe with hydraulic manifold block to reduce vibration ;
④ with rubber hoses accumulator and reduce vibration caused by the pressure pulsation , the accumulator can absorb a noise below 10 Hz , while the high frequency noise , the hydraulic hoses are very effective ;
⑤ with acoustic enclosures with a sound-absorbing material , the pump cover can effectively reduce noise ;
⑥ system should be set to deflate devices.
