德國(guó)REXROTH力士樂繼電器現(xiàn)貨庫(kù)存

繼電器是一種電控制器件，是當(dāng)輸入量（激勵(lì)量）的變化達(dá)到規(guī)定要求時(shí)，在電氣輸出電路中使被控量發(fā)生預(yù)定的階躍變化的一種電器。它具有控制系統(tǒng)（又稱輸入回路）和被控制系統(tǒng)（又稱輸出回路）之間的互動(dòng)關(guān)系。通常應(yīng)用于自動(dòng)化的控制電路中，它實(shí)際上是用小電流去控制大電流運(yùn)作的一種“自動(dòng)開關(guān)”。故在電路中起著自動(dòng)調(diào)節(jié)、安全保護(hù)、轉(zhuǎn)換電路等作用。

繼電器是具有隔離功能的自動(dòng)開關(guān)元件，廣泛應(yīng)用于遙控、遙測(cè)、通訊、自動(dòng)控制、機(jī)電一體化及電力電子設(shè)備中，是zui重要的控制元件之一。

    繼電器一般都有能反映一定輸入變量（如電流、電壓、功率、阻抗、頻率、溫度、壓力、速度、光等）的感應(yīng)機(jī)構(gòu)（輸入部分）；有能對(duì)被控電路實(shí)現(xiàn)“通”、“斷”控制的執(zhí)行機(jī)構(gòu)（輸出部分）；在繼電器的輸入部分和輸出部分之間，還有對(duì)輸入量進(jìn)行耦合隔離，功能處理和對(duì)輸出部分進(jìn)行驅(qū)動(dòng)的中間機(jī)構(gòu)（驅(qū)動(dòng)部分）。

    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。
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。

    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。
    其次用于控制執(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。

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，壓力也沒有變化，所以壓力繼電器也不會(huì)工作。
