壓力開(kāi)關(guān)主要類(lèi)別包括常開(kāi)式和常閉式。主要特點(diǎn)是：
1、采用英制管螺紋快速接頭或銅管焊接式安裝結(jié)構(gòu)，安裝靈活，使用方便，無(wú)需特殊的安裝固定。
2、插片式導(dǎo)線(xiàn)式連接方可供用戶(hù)任意選定。
3、密封式不銹鋼感應(yīng)器安全可靠。
4、壓力范圍內(nèi)可根據(jù)用戶(hù)任意選定的壓力值進(jìn)行制造。

液壓油是不可壓縮液體，因此利用液壓油是無(wú)法蓄積壓力能的，必須依靠其他介質(zhì)來(lái)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?chē)挠鸵号c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，直到系統(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
彈簧式
它依靠壓縮彈簧把液壓系統(tǒng)中的過(guò)剩壓力能轉(zhuǎn)化為彈簧勢(shì)能存儲(chǔ)起來(lái)，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。
活塞式
它通過(guò)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(lái)。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(lèi)蓄能器僅供暫存能量用。
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(mén)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(guó)內(nèi)某廠(chǎng)采用改進(jìn)彈簧式蓄能器的結(jié)構(gòu)。加大彈簧外徑（大于液壓腔直徑）、限定彈簧行程（將彈簧大載荷限定在許用極限載荷以?xún)?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(guò)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(guò)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(lèi)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。
蓄能器有兩種用途。①當(dāng)?shù)退龠\(yùn)動(dòng)時(shí)載荷需要的流量小于液壓泵流量，液壓泵多余的流量?jī)?chǔ)入蓄能器，當(dāng)載荷要求流量大于液壓泵流量時(shí)，液體從蓄能器放出來(lái)，以補(bǔ)液壓泵流量之不足。②當(dāng)停機(jī)但仍需維持一定壓力時(shí)，可以停止液壓泵而由蓄能器補(bǔ)償系統(tǒng)的泄漏，以保持系統(tǒng)的壓力。
蓄能器也可用來(lái)吸收液壓泵的壓力脈動(dòng)或吸收系統(tǒng)中產(chǎn)生的液壓沖擊壓力。蓄能器中的壓力可以用壓縮氣體、重錘或彈簧來(lái)產(chǎn)生，相應(yīng)地蓄能器分為氣體式、重錘式和彈簧式。氣體式蓄能器中的氣體與液體直接接觸者，稱(chēng)為接觸式，其結(jié)構(gòu)簡(jiǎn)單，容量大，但液體中容易混入氣體，常用于水壓機(jī)上。氣體與液體不接觸的稱(chēng)為隔離式，常用皮囊和隔膜來(lái)隔離，皮囊體積變化量大，隔膜體積變化量小，常用于吸收壓力脈動(dòng)。重錘式容量較大，常用于軋機(jī)等系統(tǒng)中，供蓄能用。

液壓比例控制系統(tǒng)
以比例控制元件完成動(dòng)力與運(yùn)動(dòng)方向控制，分為比例壓力閥、比例流量閥、比例方向閥及比例方向流量閥，可為模擬量輸入或數(shù)字量輸入，視是否帶反饋分為開(kāi)環(huán)控制與閉環(huán)控制，一般獲得頻率不是很高(10HZ)以?xún)?nèi)，高頻響閥可實(shí)現(xiàn)較高頻率。
若精度要求不高可考慮使用電液比例控制系統(tǒng)，一般電液比例控制系統(tǒng)可達(dá)至以下精度
位置精度- 3 mm
速度精度帶壓力補(bǔ)償器- 3%
加減速斜坡時(shí)間-0.5秒
壓力帶位移傳感器的產(chǎn)品-比例壓力閥設(shè)定的0.3% (如壓力設(shè)定為200bar,精度可達(dá)0.6bar)
一般的多驅(qū)動(dòng)器液壓系統(tǒng)皆要求流量及壓力控制，提供比例壓力及流量控制系統(tǒng)
開(kāi)環(huán)式比例壓力及流量控制可用于定量泵及變量泵系統(tǒng)。
速度和流量比例控制的分別是:
流量控制只控制供油量,并不控制驅(qū)動(dòng)元件的運(yùn)動(dòng)方向;
若系統(tǒng)負(fù)載及變速要求高，則要使用速度控制系統(tǒng)。
速度比例控制多用于自動(dòng)化控制、注塑機(jī)、壓力機(jī)等
使用閉環(huán)的主要原因:
保持設(shè)定值不受外來(lái)干擾所影響
→在不同的工作壓力下保持穩(wěn)定的速度
→在不同的輸出力下保證相同位置
→在帶偏載的情況下作同步移動(dòng)
提高精度要求
→位置誤差低于1 mm
→壓力誤差低于1 ba
→需要控制加減速度
高動(dòng)態(tài)要求的系統(tǒng)
→模擬應(yīng)用
→測(cè)驗(yàn)應(yīng)用
