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一步发展的因素,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 be免费信息ing increasingly severe , and impeded the further development of hydraulic technology factors , voice over 70dB noise has be免费信息e , 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
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.
