德國進口DG型HAWE壓力繼電器DG型(xing)HAWE壓(ya)(ya)(ya)力(li)(li)繼電(dian)(dian)器是液壓(ya)(ya)(ya)系統(tong)中當流體壓(ya)(ya)(ya)力(li)(li)達到預定值時(shi)，使電(dian)(dian)接(jie)點動作的元件。壓(ya)(ya)(ya)力(li)(li)繼電(dian)(dian)器也可定義為將壓(ya)(ya)(ya)力(li)(li)轉換成電(dian)(dian)信(xin)號的液壓(ya)(ya)(ya)元器件，客戶根據(ju)自身的壓(ya)(ya)(ya)力(li)(li)設(she)計需要，通過調節壓(ya)(ya)(ya)力(li)(li)繼電(dian)(dian)器，實現在某一(yi)設(she)定的壓(ya)(ya)(ya)力(li)(li)時(shi)，輸(shu)出一(yi)個(ge)電(dian)(dian)信(xin)號的功能(neng)。

HAWE液壓(ya)壓(ya)力(li)(li)繼電(dian)(dian)器是為了控(kong)制液壓(ya)系(xi)統(tong)中壓(ya)力(li)(li)的(de)穩定而設計(ji)的(de)裝置(zhi)。它利(li)用電(dian)(dian)磁力(li)(li)使機械(xie)接通或斷開，將(jiang)電(dian)(dian)信(xin)號轉換為機械(xie)控(kong)制信(xin)號，以(yi)控(kong)制油路系(xi)統(tong)的(de)開關或正常(chang)工(gong)作(zuo)狀(zhuang)態。當(dang)液壓(ya)系(xi)統(tong)中的(de)壓(ya)力(li)(li)達(da)到設定值時，繼電(dian)(dian)器會(hui)自動開啟或關閉電(dian)(dian)路，使系(xi)統(tong)達(da)到穩定工(gong)作(zuo)狀(zhuang)態。

DG型HAWE壓(ya)力(li)(li)(li)(li)(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)主(zhu)(zhu)要是通(tong)(tong)過(guo)系統壓(ya)力(li)(li)(li)(li)(li)將電(dian)(dian)(dian)信(xin)號發出從(cong)而使(shi)(shi)元器(qi)件(jian)發生特定(ding)(ding)的(de)(de)運(yun)作(zuo)(zuo)(zuo)(zuo)來使(shi)(shi)油(you)路(lu)泄壓(ya)或者換向。這(zhe)些元件(jian)會在(zai)運(yun)動(dong)(dong)(dong)(dong)時(shi)(shi)(shi)按照(zhao)設定(ding)(ding)好(hao)的(de)(de)順序進(jin)行相應操作(zuo)(zuo)(zuo)(zuo)。可(ke)以(yi)通(tong)(tong)過(guo)關閉電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機或者進(jin)行分流來有(you)(you)效的(de)(de)保護(hu)運(yun)作(zuo)(zuo)(zuo)(zuo)。哈威壓(ya)力(li)(li)(li)(li)(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)目(mu)前主(zhu)(zhu)要有(you)(you)以(yi)下4種結構，柱(zhu)塞式，膜(mo)片式，彈(dan)簧管式以(yi)及(ji)波紋管式。哈威壓(ya)力(li)(li)(li)(li)(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)運(yun)動(dong)(dong)(dong)(dong)時(shi)(shi)(shi)進(jin)油(you)口進(jin)入(ru)的(de)(de)油(you)液壓(ya)力(li)(li)(li)(li)(li)達到設定(ding)(ding)的(de)(de)壓(ya)力(li)(li)(li)(li)(li)值時(shi)(shi)(shi)，可(ke)以(yi)隨著(zhu)推動(dong)(dong)(dong)(dong)柱(zhu)塞向上移動(dong)(dong)(dong)(dong)通(tong)(tong)過(guo)杠桿進(jin)行放大然后推動(dong)(dong)(dong)(dong)微動(dong)(dong)(dong)(dong)開關進(jin)行運(yun)動(dong)(dong)(dong)(dong)。這(zhe)樣(yang)就可(ke)以(yi)改變彈(dan)簧的(de)(de)壓(ya)縮(suo)量進(jin)而起到調節繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)動(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)的(de)(de)壓(ya)力(li)(li)(li)(li)(li)。這(zhe)就是整個哈威壓(ya)力(li)(li)(li)(li)(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)的(de)(de)工作(zuo)(zuo)(zuo)(zuo)程序。因此(ci)哈威壓(ya)力(li)(li)(li)(li)(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)在(zai)現(xian)如(ru)今主(zhu)(zhu)要用(yong)來進(jin)行安全保護(hu)等工作(zuo)(zuo)(zuo)(zuo)。

HAWE哈威壓(ya)(ya)力繼(ji)電(dian)(dian)器(qi)受(shou)到壓(ya)(ya)力負載時閉合或斷開(kai)電(dian)(dian)觸點(dian)。 當達到設定的(de)壓(ya)(ya)力值時，它能(neng)為下一工序發出(chu)電(dian)(dian)控制指令或信號。 V各種(zhong)不同結(jie)構形(xing)(xing)式(shi)的(de)壓(ya)(ya)力繼(ji)電(dian)(dian)器(qi)（在刻度盤上用旋鈕進行壓(ya)(ya)力設定的(de)形(xing)(xing)式(shi)，主(zhu)壓(ya)(ya)力繼(ji)電(dian)(dian)器(qi)和輔助壓(ya)(ya)力繼(ji)電(dian)(dian)器(qi)形(xing)(xing)式(shi)，板接式(shi)壓(ya)(ya)力繼(ji)電(dian)(dian)器(qi)形(xing)(xing)式(shi)）能(neng)適用于(yu)不同的(de)使用場合。 由于(yu)結(jie)構原因，上切(qie)換(huan)點(dian)和下切(qie)換(huan)點(dian)之間必須考慮 8 - 20% 差(cha)值（與每個z高允(yun)許調節壓(ya)(ya)力有關(guan)）。 此外，在 DG5E 和 DG6 型壓(ya)(ya)力繼(ji)電(dian)(dian)器(qi)上可選擇(ze)二個獨立的(de)壓(ya)(ya)力開(kai)關(guan)點(dian)和/或編程或設定差(cha)值。
