蓄能器是液壓氣動(dòng)系統(tǒng)中的一種能量儲(chǔ)蓄裝置。它在適當(dāng)?shù)臅r(shí)機(jī)將系統(tǒng)中的能量轉(zhuǎn)變?yōu)閴嚎s能或位能儲(chǔ)存起來,當(dāng)系統(tǒng)需要時(shí),又將壓縮能或位能轉(zhuǎn)變?yōu)橐簤夯驓鈮旱饶芏尫懦鰜恚匦卵a(bǔ)供給系統(tǒng)。當(dāng)系統(tǒng)瞬間壓力增大時(shí),它可以吸收這部分的能量,以保證整個(gè)系統(tǒng)壓力正常。
液壓油是不可壓縮液體,因此利用液壓油是無法蓄積壓力能的,必須依靠其他介質(zhì)來轉(zhuǎn)換、蓄積壓力能。例如,利用氣體(氮?dú)猓┑目蓧嚎s性質(zhì)研制的皮囊式充氣蓄能器就是一種蓄積液壓油的裝置。皮囊式蓄能器由油液部分和帶有氣密封件的氣體部分組成,位于皮囊周圍的油液與油液回路接通。當(dāng)壓力升高時(shí)油液進(jìn)入蓄能器,氣體被壓縮,系統(tǒng)管路壓力不再上升;當(dāng)管路壓力下降時(shí)壓縮空氣膨脹,將油液壓入回路,從而減緩管路壓力的下降。
蓄能器按加載方式可分為
REXROTH蓄能器HAD1,4-140-1X/20Z06C-1N111-CE
重錘式
它通過提升加載在密封活塞上的質(zhì)量塊把液壓系統(tǒng)中的壓力能轉(zhuǎn)化為重力勢(shì)能積蓄起來。其結(jié)構(gòu)簡(jiǎn)單、壓力穩(wěn)定。缺點(diǎn)是安裝局限性大,只能垂直安裝;不易密封;質(zhì)量塊慣性大,不靈敏。這類蓄能器僅供暫存能量用。
彈簧式
它依靠壓縮彈簧把液壓系統(tǒng)中的過剩壓力能轉(zhuǎn)化為彈簧勢(shì)能存儲(chǔ)起來,需要時(shí)釋放出去。其結(jié)構(gòu)簡(jiǎn)單,成本較低。但是因?yàn)閺椈缮炜s量有限,而且彈簧的伸縮對(duì)壓力變化不敏感,消振功能差,所以只適合小容量、低壓系統(tǒng)(P≦1.0~1.2MPa),或者用作緩沖裝置。
這兩種蓄能器因?yàn)槠渚窒扌砸呀?jīng)很少采用。但值得注意的是,有些研究部門從經(jīng)濟(jì)角度考慮在這兩種蓄能器的結(jié)構(gòu)上做一些改進(jìn),在一定程度上克服了其缺點(diǎn)。比如國內(nèi)某廠采用改進(jìn)彈簧式蓄能器的結(jié)構(gòu)。如圖2所示,加大彈簧外徑(大于液壓腔直徑)、限定彈簧行程(將彈簧zui大載荷限定在許用極限載荷以內(nèi))的方法提高了蓄能器的工作壓力和容量,降低了成本。
氣體式
它以波義爾定律(PVn=K=常數(shù))為基礎(chǔ),通過壓縮氣體完成能量轉(zhuǎn)化,使用時(shí)首先向蓄能器充入預(yù)定壓力的氣體。當(dāng)系統(tǒng)壓力超過蓄能器內(nèi)部壓力時(shí),油液壓縮氣體,將油液中的壓力轉(zhuǎn)化為氣體內(nèi)能;當(dāng)系統(tǒng)壓力低于蓄能器內(nèi)部壓力時(shí),蓄能器中的油在高壓氣體的作用下流向外部系統(tǒng),釋放能量。選擇適當(dāng)?shù)某錃鈮毫κ沁@種蓄能器的關(guān)鍵。這類蓄能器按結(jié)構(gòu)可分為管路消振器、氣液直接接觸式、活塞式、隔膜式、氣囊式等。

蓄能器的種類主要分為彈簧式和充氣式。
蓄能器的功用
(1)短期大量供油
(2)系統(tǒng)保壓
(3)應(yīng)急能源
(4)緩和沖擊壓力
(5)吸收脈動(dòng)壓力
蓄能器的功能主要分為存儲(chǔ)能量、吸收液壓沖擊、消除脈動(dòng)和回收能量四大類。
*類存儲(chǔ)能量。這一類功用在實(shí)際使用中又可細(xì)分為①作輔助動(dòng)力源,減小裝機(jī)容量;②補(bǔ)償泄漏;③作熱膨脹補(bǔ)償;④作緊急動(dòng)力源;⑤構(gòu)成恒壓油源。
第二類吸收液壓沖擊。換向閥突然換向、執(zhí)行元件運(yùn)動(dòng)的突然停止都會(huì)在液壓系統(tǒng)中產(chǎn)生壓力沖擊,使系統(tǒng)壓力在短時(shí)間內(nèi)快速升高,造成儀表、元件和密封裝置的損壞,并產(chǎn)生振動(dòng)和噪聲。為保證吸收效果,蓄能器應(yīng)設(shè)置在沖擊點(diǎn)附近,所以蓄能器一般裝設(shè)在控制閥或液壓缸等沖擊源之前,可以很好地吸收和緩沖液壓沖擊。
第三類消除脈動(dòng)、降低噪聲。對(duì)于采用柱塞泵且其柱塞數(shù)較少的液壓系統(tǒng),泵流量周期變化使系統(tǒng)產(chǎn)生振動(dòng)。裝設(shè)蓄能器,可以大量吸收脈動(dòng)壓力和流量中的能量,在流量脈動(dòng)的一個(gè)周期內(nèi)。瞬時(shí)流量高于平均流量的部分油液被蓄能器吸收,低于平均流量部分由蓄能器補(bǔ)充,這就吸收了脈動(dòng)中的能量,降低了脈動(dòng),減小了對(duì)敏感儀器和設(shè)備的損壞程茺。
第四類回收能量。用蓄能器回收能量是目前研究較多的一個(gè)領(lǐng)域。能量回收可以提高能量利用率,是節(jié)能的一個(gè)重要途徑。蓄能器因?yàn)榭梢詴捍婺芰浚钥梢杂脕砘厥斩喾N功能、位置勢(shì)能。這方面的主要研究有①回收車輛制動(dòng)能量;②回收工程機(jī)械動(dòng)臂機(jī)構(gòu)位能;③回收液壓挖掘機(jī)轉(zhuǎn)臺(tái)制動(dòng)能量;④回收石油修井機(jī)及鉆機(jī)管下落重力勢(shì)能;⑤回收電梯下行重力勢(shì)能。
