因?yàn)橐簤合到y(tǒng)的振動(dòng)和噪聲本身不可避免,而且近幾年,跟著液壓技術(shù)向高速、高壓和大功率方向的發(fā)展,液壓系統(tǒng)的噪聲也日趨嚴(yán)峻,并且成為妨礙液壓技術(shù)進(jìn)一步發(fā)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(jīng)日益受到人們的正視。因此研究和分析液壓噪聲和振動(dòng)的機(jī)理,從而減少與降低振動(dòng)和噪聲,并改善液壓系統(tǒng)的機(jī)能,有著積極而深遠(yuǎn)的意義。 降低液壓系統(tǒng)噪聲的措施:
為減少噪聲,必需對噪聲源進(jìn)行實(shí)際調(diào)查,丈量分析液壓系統(tǒng)的聲壓級(jí),進(jìn)行頻率分析,從而把握噪聲源的大小及頻率特性,采取相應(yīng)辦法,詳細(xì)列舉如下:
① 使用低噪聲電機(jī);并使用彈性聯(lián)軸器,以減少該環(huán)節(jié)引起的振動(dòng)和噪聲;
?、?nbsp;在電念頭,液壓泵和液壓閥的安裝面上應(yīng)設(shè)置防振膠墊;
?、?nbsp;盡量用液壓集成塊代替管道,以減少振動(dòng);
④ 用蓄能器和橡膠軟管減少由壓力脈動(dòng)引起的振動(dòng),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;
?、?nbsp;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(tǒng)中應(yīng)設(shè)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.
