武漢百士自動(dòng)化設(shè)備有限公司專(zhuān)注于液壓、氣動(dòng)、工控自動(dòng)化備件銷(xiāo)售，熱誠(chéng)歡迎新老客戶(hù)咨詢(xún)購(gòu)買(mǎi)！

1.壓力繼電器，液壓術(shù)語(yǔ)，是液壓系統(tǒng)中當(dāng)流體壓力達(dá)到預(yù)定值時(shí)，使電接點(diǎn)動(dòng)作的元件。

2.是將壓力轉(zhuǎn)換成電信號(hào)的液壓元器件，客戶(hù)根據(jù)自身的壓力設(shè)計(jì)需要，通過(guò)調(diào)節(jié)壓力繼電器，實(shí)現(xiàn)在某一設(shè)定的壓力時(shí)，輸出一個(gè)電信號(hào)的功能。

工作原理

壓力繼電器是利用液體的壓力來(lái)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。

壓力繼電器有柱塞式、膜片式、彈簧管式和波紋管式四種結(jié)構(gòu)形式。下面對(duì)柱塞式壓力繼電器（見(jiàn)圖）的工作原理作一介紹：

當(dāng)從繼電器下端進(jìn)油口3進(jìn)入的液體壓力達(dá)到調(diào)定壓力值時(shí)，推動(dòng)柱塞2上移，此位移通過(guò)杠桿放大后推動(dòng)微動(dòng)開(kāi)關(guān)4動(dòng)作。改變彈簧1的壓縮量，可以調(diào)節(jié)繼電器的動(dòng)作壓力。

應(yīng)用場(chǎng)合：用于安全保護(hù)、控制執(zhí)行元件的順序動(dòng)作、用于泵的啟閉、用于泵的卸荷。

注意： 壓力繼電器必須放在壓力有明顯變化的地方才能輸出電信號(hào)。若將壓力繼電器放在回油路上，由于回油路直接接回油箱，壓力也沒(méi)有變化，所以壓力繼電器也不會(huì)工作。

2選用標(biāo)準(zhǔn)

根據(jù)所測(cè)對(duì)象的壓力來(lái)選用,比如所測(cè)壓力范圍在8KG以?xún)?nèi),那么就要選用額定10KG的壓力繼電器,還有要符合電路中的額定電壓,接口管徑的大小

3使用方法

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(kāi)關(guān)的常開(kāi)觸點(diǎn)始終閉合。若工件沒(méi)有夾緊，壓力繼電器2斷開(kāi)，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。

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。

較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(kāi)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(kāi)關(guān)，將常閉觸點(diǎn)斷開(kāi)，使液壓泵停轉(zhuǎn)。在加工過(guò)程中減慢液壓缸的速度，同時(shí)減少動(dòng)力消耗。

4使用技巧

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