因為液壓系統的振動和噪聲本身不可避免，而且近幾年，跟著液壓技術向高速、高壓和大功率方向的發展，液壓系統的噪聲也日趨嚴峻，并且成為妨礙液壓技術進一步發展的因素，聲音超過70dB便成為噪聲，使人聽起來極不愜意，甚至使人煩燥不安，噪聲作為污染已經日益受到人們的正視。因此研究和分析液壓噪聲和振動的機理，從而減少與降低振動和噪聲，并改善液壓系統的機能，有著積極而深遠的意義。 降低液壓系統噪聲的措施：
為減少噪聲，必需對噪聲源進行實際調查，丈量分析液壓系統的聲壓級，進行頻率分析，從而把握噪聲源的大小及頻率特性，采取相應辦法，詳細列舉如下：
① 使用低噪聲電機；并使用彈性聯軸器，以減少該環節引起的振動和噪聲；
② 在電念頭，液壓泵和液壓閥的安裝面上應設置防振膠墊；
③ 盡量用液壓集成塊代替管道，以減少振動；
④ 用蓄能器和橡膠軟管減少由壓力脈動引起的振動，蓄能器能吸收10 Hz以下的噪聲，而高頻噪聲，用液壓軟管則十分有效；
⑤ 用帶有吸聲材料的隔聲罩，將液壓泵罩上也能有效地降低噪聲；
⑥ 系統中應設置放氣裝置。

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.
