壓力繼(ji)電器的(de)使用(yong)方法(fa)是(shi)什么?壓力繼(ji)電器的(de)作用(yong)便是(shi)有一種保護(hu)的(de)作用(yong)，可以控制實行元件的(de)次第動作，下面(mian)是(shi)儀(yi)器儀(yi)表網給(gei)我們敘述的(de)各自的(de)用(yong)法(fa)。

　　要用于保護(hu)時，將壓(ya)力(li)(li)繼電器(qi)設置在(zai)夾緊液壓(ya)缸的(de)(de)一(yi)端(duan)(duan)，液壓(ya)泵發(fa)起(qi)后，要將工(gong)(gong)(gong)件夾緊，此時夾緊液壓(ya)缸的(de)(de)右腔壓(ya)力(li)(li)增加，當增加到壓(ya)力(li)(li)繼電器(qi)的(de)(de)調定值時，壓(ya)力(li)(li)繼電器(qi)動(dong)作，電信(xin)號(hao)使2YA通電，所(suo)以切削液壓(ya)缸進(jin)刀(dao)切削。在(zai)加工(gong)(gong)(gong)期間(jian)，壓(ya)力(li)(li)繼電器(qi)微動(dong)開(kai)關的(de)(de)常開(kai)觸點一(yi)直閉合。若工(gong)(gong)(gong)件沒(mei)有夾緊，壓(ya)力(li)(li)繼電器(qi)2斷開(kai)，所(suo)以2YA斷電，切削液壓(ya)缸當即間(jian)斷進(jin)刀(dao)，然后防止工(gong)(gong)(gong)件未夾緊被切削而出事(shi)端(duan)(duan)。智能溫(wen)(wen)控儀，高溫(wen)(wen)測濕變送器(qi)，羅卓尼克(ke)溫(wen)(wen)濕度變送器(qi)HF532-WB，不銹鋼電熱管,PT100熱電阻感(gan)應探頭(tou)，紅(hong)外線測溫(wen)(wen)儀，溫(wen)(wen)濕度傳感(gan)器(qi)HC2A-S。

　　本來(lai)用于(yu)控制實行元件(jian)的(de)次第(di)動作時，液(ye)壓(ya)(ya)(ya)泵發起(qi)后，要2YA通(tong)電(dian)(dian)(dian)(dian)，液(ye)壓(ya)(ya)(ya)缸左腔(qiang)進(jin)油(you)，推(tui)(tui)動活(huo)塞(sai)方向右移(yi)。當碰到(dao)限位器(或死擋鐵)后，體系(xi)壓(ya)(ya)(ya)力(li)(li)增(zeng)加，壓(ya)(ya)(ya)力(li)(li)繼電(dian)(dian)(dian)(dian)器宣(xuan)布電(dian)(dian)(dian)(dian)信號，使1YA通(tong)電(dian)(dian)(dian)(dian)，高壓(ya)(ya)(ya)油(you)進(jin)入液(ye)壓(ya)(ya)(ya)缸的(de)左腔(qiang)，推(tui)(tui)動活(huo)塞(sai)右移(yi)。這時若(ruo)HKT變送(song)器也通(tong)電(dian)(dian)(dian)(dian)，液(ye)壓(ya)(ya)(ya)缸的(de)活(huo)塞(sai)敏捷右移(yi);若(ruo)3YA斷電(dian)(dian)(dian)(dian)，則液(ye)壓(ya)(ya)(ya)缸的(de)活(huo)塞(sai)慢速右移(yi)，其慢速運動速度由節流閥(fa)調理。

　　再(zai)次用于液壓(ya)(ya)泵(beng)卸荷時，壓(ya)(ya)力(li)繼電器不是控(kong)制液壓(ya)(ya)泵(beng)間(jian)斷翻滾，而是控(kong)制二位二通電磁(ci)閥，將液壓(ya)(ya)泵(beng)5輸出的(de)壓(ya)(ya)力(li)油流回油箱，使其卸荷。

　　終究用(yong)(yong)于液(ye)(ye)壓(ya)(ya)(ya)泵(beng)(beng)的啟(qi)閉時(shi)，有兩(liang)個(ge)液(ye)(ye)壓(ya)(ya)(ya)泵(beng)(beng)，高壓(ya)(ya)(ya)小流量(liang)泵(beng)(beng)，低(di)壓(ya)(ya)(ya)大流量(liang)泵(beng)(beng)。當活塞敏捷下降時(shi)，兩(liang)泵(beng)(beng)一同(tong)輸(shu)出(chu)壓(ya)(ya)(ya)力(li)油(you)。當液(ye)(ye)壓(ya)(ya)(ya)缸活塞桿抵(di)住工件(jian)初步加(jia)壓(ya)(ya)(ya)時(shi)，壓(ya)(ya)(ya)力(li)繼電器(qi)在壓(ya)(ya)(ya)力(li)油(you)作用(yong)(yong)下宣布動(dong)(dong)(dong)作，觸(chu)動(dong)(dong)(dong)微動(dong)(dong)(dong)開(kai)關，將常閉觸(chu)點斷開(kai)，使液(ye)(ye)壓(ya)(ya)(ya)泵(beng)(beng)停轉。在加(jia)工過程中(zhong)減(jian)慢液(ye)(ye)壓(ya)(ya)(ya)缸的速度(du)，一同(tong)削減(jian)動(dong)(dong)(dong)力(li)消(xiao)耗。
