HYDAC賀德克DES壓力繼電器電廠專用HYDAC賀(he)德克DES壓(ya)(ya)力繼(ji)電器(qi)應用(yong)(yong)場合：用(yong)(yong)于(yu)安全保護、控(kong)制執(zhi)行(xing)元件的(de)順(shun)序動(dong)作(zuo)、用(yong)(yong)于(yu)泵的(de)啟閉(bi)、用(yong)(yong)于(yu)泵的(de)卸荷。注意：壓(ya)(ya)力繼(ji)電器(qi)必須放(fang)在壓(ya)(ya)力有明顯變(bian)化的(de)地(di)方才(cai)能(neng)輸(shu)出電信號。若將壓(ya)(ya)力維電器(qi)放(fang)在回油(you)路上，由于(yu)回油(you)路直接接回油(you)箱(xiang)，壓(ya)(ya)力也沒有變(bian)化，所(suo)以壓(ya)(ya)力繼(ji)電器(qi)也不會工(gong)作(zuo)。

德國HYDAC壓力繼電器的工作原理(li)如下：

1、壓(ya)力繼電器主要用于對液(ye)體或氣體壓(ya)力的高(gao)低進(jin)行(xing)檢測并發出開關量信號，以控(kong)制(zhi)電磁(ci)閥、液(ye)壓(ya)泵等(deng)設備對壓(ya)力的高(gao)低進(jin)行(xing)控(kong)制(zhi)。

2、壓(ya)力(li)(li)繼(ji)電器主要由壓(ya)力(li)(li)傳送(song)裝置和微動開(kai)關等組成(cheng)，液體或氣體壓(ya)力(li)(li)經壓(ya)力(li)(li)入口推動橡皮膜和滑桿(gan)，克服彈簧反力(li)(li)向上運(yun)動，當壓(ya)力(li)(li)達(da)到擬(ni)(ni)定壓(ya)力(li)(li)時，觸動微動開(kai)關，發出(chu)控制信號，旋轉(zhuan)調壓(ya)螺母可以改變擬(ni)(ni)定壓(ya)力(li)(li)。

3、壓(ya)力(li)繼電(dian)(dian)器(qi)(qi)是利用(yong)液(ye)體的壓(ya)力(li)來啟閉電(dian)(dian)氣(qi)觸(chu)點的液(ye)壓(ya)電(dian)(dian)氣(qi)轉換元(yuan)件(jian)。當系(xi)(xi)統壓(ya)力(li)達到壓(ya)力(li)繼電(dian)(dian)器(qi)(qi)的調(diao)定值(zhi)時，發出電(dian)(dian)信號，使電(dian)(dian)氣(qi)元(yuan)件(jian)（如(ru)電(dian)(dian)磁(ci)鐵、電(dian)(dian)機、時間繼電(dian)(dian)器(qi)(qi)、電(dian)(dian)磁(ci)離合器(qi)(qi)等(deng)）動(dong)作(zuo)，使油(you)路卸壓(ya)、換向，執行(xing)元(yuan)件(jian)實現(xian)順(shun)序(xu)動(dong)作(zuo)，或關(guan)閉電(dian)(dian)動(dong)機使系(xi)(xi)統停止工作(zuo)，起(qi)安全保護作(zuo)用(yong)等(deng)。

4、當從繼電(dian)器下(xia)端進油口3進入的(de)液體壓力達到調(diao)定壓力值時(shi)，推(tui)動(dong)柱塞2上移(yi)，此位移(yi)通過杠桿(gan)放大后推(tui)動(dong)微動(dong)開(kai)關4動(dong)作(zuo)。改變彈簧1的(de)壓縮(suo)量，可(ke)以調(diao)節繼電(dian)器的(de)動(dong)作(zuo)壓力。

熱繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是用(yong)于電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)或其它電(dian)(dian)(dian)(dian)(dian)(dian)氣設備、電(dian)(dian)(dian)(dian)(dian)(dian)氣線路的過(guo)(guo)載保護(hu)的保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)在(zai)實際運行中，如(ru)拖(tuo)動(dong)(dong)(dong)(dong)(dong)生產機(ji)(ji)(ji)(ji)械進行工作過(guo)(guo)程中，若機(ji)(ji)(ji)(ji)械出現不(bu)正常(chang)的情況或電(dian)(dian)(dian)(dian)(dian)(dian)路異常(chang)使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)遇到過(guo)(guo)載，則(ze)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)轉速下降、繞組(zu)中的電(dian)(dian)(dian)(dian)(dian)(dian)流將(jiang)增(zeng)大，使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的繞組(zu)溫(wen)度(du)升高。若過(guo)(guo)載電(dian)(dian)(dian)(dian)(dian)(dian)流不(bu)大且過(guo)(guo)載的時間較短，電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)繞組(zu)不(bu)超過(guo)(guo)允(yun)許(xu)溫(wen)升，這種過(guo)(guo)載是允(yun)許(xu)的。但(dan)若過(guo)(guo)載時間長，過(guo)(guo)載電(dian)(dian)(dian)(dian)(dian)(dian)流大，電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)繞組(zu)的溫(wen)升就會超過(guo)(guo)允(yun)許(xu)值，使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)繞組(zu)老化，縮短電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的使(shi)(shi)用(yong)壽命(ming)，嚴重時甚至會使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)繞組(zu)燒(shao)毀。所以，這種過(guo)(guo)載是電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)不(bu)能承受(shou)的。熱繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)就是利用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)流的熱效(xiao)應原理，在(zai)出現電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)不(bu)能承受(shou)的過(guo)(guo)載時切(qie)斷電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)路，為電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)提供(gong)過(guo)(guo)載保護(hu)的保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。
