德國REXROTH力士樂繼電器現(xiàn)貨庫存 REXROTH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。 力士樂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)。 REXROTH繼電器操作說明: 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。 R901182344 HED 5 OH-3X/50K14 R901186325 HED 5 OH-3X/50K14V R901225114 HED 5 OH-3X/50K35 R901185727 HED 5 OH-3X/100K14

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。
