壓力繼電器是利用液體的壓力來啟閉電氣觸點(diǎn)的液壓電氣轉(zhuǎn)換元件。當(dāng)系統(tǒng)壓力達(dá)到壓力繼電器的調(diào)定值時(shí)，發(fā)出電信號(hào)，使電氣元件（如電磁鐵、電機(jī)、時(shí)間繼電器、電磁離合器等）動(dòng)作，使油路卸壓、換向，執(zhí)行元件實(shí)現(xiàn)順序動(dòng)作，或關(guān)閉電動(dòng)機(jī)使系統(tǒng)停止工作，起安全保護(hù)作用等。

首先用于安全保護(hù)時(shí)，將壓力繼電器設(shè)置在夾緊液壓缸的一端，液壓泵啟動(dòng)后，首先將工件夾緊

，此時(shí)夾緊液壓缸的右腔壓力升高，當(dāng)升高到壓力繼電器的調(diào)定值時(shí)，壓力繼電器動(dòng)作，發(fā)出電

信號(hào)使2YA通電，于是切削液壓缸進(jìn)刀切削。在加工期間，壓力繼電器微動(dòng)開關(guān)的常開觸點(diǎn)始終閉

合。若工件沒有夾緊，壓力繼電器2斷開，于是2YA斷電，切削液壓缸立即停止進(jìn)刀，從而避免工

件未夾緊被切削而出事故。[1] 
其實(shí)用于控制執(zhí)行元件的順序動(dòng)作時(shí)，液壓泵啟動(dòng)后，首先2YA通電，液壓缸左腔進(jìn)油，推動(dòng)活塞

方向右移。當(dāng)碰到限位器(或死擋鐵)后，系統(tǒng)壓力升高，壓力繼電器發(fā)出電信號(hào)，使1YA通電，高

壓油進(jìn)入液壓缸的左腔，推動(dòng)活塞右移。這時(shí)若3YA也通電，液壓缸的活塞快速右移;若3YA斷電，

則液壓缸的活塞慢速右移，其慢速運(yùn)動(dòng)速度由節(jié)流閥調(diào)節(jié)。
再次用于液壓泵卸荷時(shí)，壓力繼電器不是控制液壓泵停止轉(zhuǎn)動(dòng)，而是控制二位二通電磁閥，將液

壓泵5輸出的壓力油流回油箱，使其卸荷。
zui后用于液壓泵的啟閉時(shí)，有兩個(gè)液壓泵，高壓小流量泵，低壓大流量泵。當(dāng)活塞快速下降時(shí)，

兩泵同時(shí)輸出壓力油。當(dāng)液壓缸活塞桿抵住工件開始加壓時(shí)，壓力繼電器在壓力油作用下發(fā)出動(dòng)

作，觸動(dòng)微動(dòng)開關(guān)，將常閉觸點(diǎn)斷開，使液壓泵停轉(zhuǎn)。在加工過程中減慢液壓缸的速度，同時(shí)減

少動(dòng)力消耗。

壓力繼電器可以感知系統(tǒng)的壓力，并且發(fā)出開關(guān)信號(hào)。壓力到了，常開觸點(diǎn)閉合，常閉觸點(diǎn)打開

。我們便可以在程序上加以利用。但是在實(shí)際使用的時(shí)候，我們會(huì)碰到一些問題。
首先是選擇的產(chǎn)品質(zhì)量有問題，主要體現(xiàn)在以下幾個(gè)方面
1、動(dòng)作不靈敏，壓力到了還沒有信號(hào)輸出。這是制造上有問題，servopiston和u-seal太緊了，

工廠出廠的時(shí)候沒有測(cè)試。
2、還沒有到壓力就發(fā)訊。裝配的問題。壓力繼電器里面的微動(dòng)開關(guān)沒有裝好。
3、產(chǎn)品不耐用，沒幾下壓力繼電器就不動(dòng)作了。廠商無良心，用了很差的微動(dòng)開關(guān)。
4、漏油。要不是密封圈沒有選好就是加工超差了。
以上列的幾點(diǎn)都是供應(yīng)商的問題，那用戶有問題，也會(huì)使壓力繼電器不工作。
低級(jí)錯(cuò)誤：
1、沒有輸出信號(hào)：測(cè)壓的小孔被生料帶堵住了，裝配工人不小心。
2、測(cè)壓不準(zhǔn)：現(xiàn)象是壓力表還沒有到壓力表指示壓力，繼電器就發(fā)訊了。事實(shí)上，壓力繼電器的

動(dòng)作速度會(huì)比壓力表快，特別是比充油式耐震壓力表。所以可能壓力表才跑到10M，壓力繼電器已

經(jīng)是20M啦。

壓力繼電器可以感知系統(tǒng)的壓力，并且發(fā)出開關(guān)信號(hào)。壓力到了，常開觸點(diǎn)閉合，常閉觸點(diǎn)打開

。我們便可以在程序上加以利用。但是在實(shí)際使用的時(shí)候，我們會(huì)碰到一些問題。
首先是選擇的產(chǎn)品質(zhì)量有問題，主要體現(xiàn)在以下幾個(gè)方面
1、動(dòng)作不靈敏，壓力到了還沒有信號(hào)輸出。這是制造上有問題，servopiston和u-seal太緊了，

工廠出廠的時(shí)候沒有測(cè)試。
2、還沒有到壓力就發(fā)訊。裝配的問題。壓力繼電器里面的微動(dòng)開關(guān)沒有裝好。
3、產(chǎn)品不耐用，沒幾下壓力繼電器就不動(dòng)作了。廠商無良心，用了很差的微動(dòng)開關(guān)。
4、漏油。要不是密封圈沒有選好就是加工超差了。
以上列的幾點(diǎn)都是供應(yīng)商的問題，那用戶有問題，也會(huì)使壓力繼電器不工作。
低級(jí)錯(cuò)誤：
1、沒有輸出信號(hào)：測(cè)壓的小孔被生料帶堵住了，裝配工人不小心。
2、測(cè)壓不準(zhǔn)：現(xiàn)象是壓力表還沒有到壓力表指示壓力，繼電器就發(fā)訊了。事實(shí)上，壓力繼電器的

動(dòng)作速度會(huì)比壓力表快，特別是比充油式耐震壓力表。所以可能壓力表才跑到10M，壓力繼電器已

經(jīng)是20M啦。
