德國REXROTH力士樂繼電器一級代理 繼電器是一種電控制器件，是當輸入量（激勵量）的變化達到規(guī)定要求時，在電氣輸出電路中使被控量發(fā)生預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）之間的互動關系。通常應用于自動化的控制電路中，它實際上是用小電流去控制大電流運作的一種“自動開關”。故在電路中起著自動調節(jié)、安全保護、轉換電路等作用。 繼電器是具有隔離功能的自動開關元件，廣泛應用于遙控、遙測、通訊、自動控制、機電一體化及電力電子設備中，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）的感應機構（輸入部分）；有能對被控電路實現(xiàn)“通”、“斷”控制的執(zhí)行機構（輸出部分）；在繼電器的輸入部分和輸出部分之間，還有對輸入量進行耦合隔離，功能處理和對輸出部分進行驅動的中間機構（驅動部分）。 壓力繼電器是利用液體的壓力來啟閉電氣觸點的液壓電氣轉換元件。當系統(tǒng)壓力達到壓力繼電器的調定值時，發(fā)出電信號，使電氣元件（如電磁鐵、電機、時間繼電器、電磁離合器等）動作，使油路卸壓、換向，執(zhí)行元件實現(xiàn)順序動作，或關閉電動機使系統(tǒng)停止工作，起安全保護作用等。
壓力繼電器有柱塞式、膜片式、彈簧管式和波紋管式四種結構形式。 EDS 344-2-040-000 EDS 344-3-600-000

EDS 344-3-016-000 首先用于安全保護時，將壓力繼電器設置在夾緊液壓缸的一端，液壓泵啟動后，首先將工件夾緊，此時夾緊液壓缸的右腔壓力升高，當升高到壓力繼電器的調定值時，壓力繼電器動作，發(fā)出電信號使2YA通電，于是切削液壓缸進刀切削。在加工期間，壓力繼電器微動開關的常開觸點始終閉合。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刀，從而避免工件未夾緊被切削而出事故。
其實用于控制執(zhí)行元件的順序動作時，液壓泵啟動后，首先2YA通電，液壓缸左腔進油，推動活塞方向右移。當碰到限位器(或死擋鐵)后，系統(tǒng)壓力升高，壓力繼電器發(fā)出電信號，使1YA通電，高壓油進入液壓缸的左腔，推動活塞右移。這時若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，其慢速運動速度由節(jié)流閥調節(jié)。
再次用于液壓泵卸荷時，壓力繼電器不是控制液壓泵停止轉動，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，有兩個液壓泵，高壓小流量泵，低壓大流量泵。當活塞快速下降時，兩泵同時輸出壓力油。當液壓缸活塞桿抵住工件開始加壓時，壓力繼電器在壓力油作用下發(fā)出動作，觸動微動開關，將常閉觸點斷開，使液壓泵停轉。在加工過程中減慢液壓缸的速度，同時減少動力消耗。 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。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工作。 德國REXROTH力士樂繼電器一級代理 本公司為“上海維特銳”，主要負責內地進口液壓，氣動品牌的銷售和服務，從德國、美國、日本、瑞典、香港、新加坡等國家直接進口液壓、氣動及工控產品，主要品牌：日本（NACHI、TOYOOKI、DAIKIN、CKD、KOGANEI、SUNX、KEYENCE、MACOME）德國（EPRO、FESTO、BURKERT、REXROTH、P+F、TURCK、IFM、PILZ、GSR、BALLUFF、HYDAC、HIRSCHMANN、HERION、HAWE、E+H）美國（MOOG、ASCO、MAC、PARKER、VICKERS）意大利（ATOS、UNIVER、AMISCO、CAMOZZI）瑞士（CARLO GAVAZZI、CONTRINEX）液壓及氣動工控產品等，經過過多的經銷商，從而以*廉的價格提供適合市場要求的優(yōu)質產品。 R901182344 HED 5 OH-3X/50K14
