DS-100-P0-300-S-P壓力繼電器是將壓(ya)力轉(zhuan)換成電信(xin)號的(de)液壓(ya)元器件,客戶根據自(zi)身的(de)壓(ya)力設計(ji)需要,通過調節壓(ya)力繼電器,實現在(zai)某一設定的(de)壓(ya)力時,輸出(chu)一個電信(xin)號的(de)功能。
壓(ya)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。下(xia)面對
圖1 柱塞(sai)式壓力繼電器
柱塞式(shi)壓力繼電器(見(jian)圖(tu)1)的工(gong)作(zuo)原理作(zuo)一(yi)介紹:
當從繼電器(qi)下端進(jin)油口3進(jin)入的液體壓力(li)達到(dao)調定壓力(li)值時,推動(dong)柱塞2上移,此位移通過杠桿放大后推動(dong)微(wei)動(dong)開(kai)關4動(dong)作(zuo)。改(gai)變彈簧1的壓縮量,可以調節繼電器(qi)的動(dong)作(zuo)壓力(li)。
應用(yong)(yong)場合:用(yong)(yong)于安全保(bao)護、控制執行(xing)元件(jian)的(de)(de)順序(xu)動作(zuo)、用(yong)(yong)于泵(beng)的(de)(de)啟閉(bi)、用(yong)(yong)于泵(beng)的(de)(de)卸荷(he)。
注意: 壓(ya)(ya)力繼(ji)電器(qi)(qi)必須放(fang)在壓(ya)(ya)力有明顯變化的(de)地方才能輸(shu)出電信號(hao)。若將(jiang)壓(ya)(ya)力繼(ji)電器(qi)(qi)放(fang)在回(hui)油路上,由于(yu)回(hui)油路直接接回(hui)油箱(xiang),壓(ya)(ya)力也(ye)沒有變化,所(suo)以壓(ya)(ya)力繼(ji)電器(qi)(qi)也(ye)不會工作(zuo)。
福伊特DS-100-P0-300-S-P壓力繼電器性能特點:
(1)調壓(ya)范(fan)圍
壓(ya)力繼電器能夠發出電信(xin)號的低(di)工(gong)作壓(ya)力和高工(gong)作壓(ya)力的范圍稱為調壓(ya)范圍。
(2)靈敏度與通(tong)斷調節(jie)區間(jian)
系(xi)統壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)升(sheng)高(gao)到壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)(de)調定值(zhi)(zhi)時(shi)(shi),壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)動作接(jie)通(tong)電(dian)(dian)(dian)信(xin)號的(de)(de)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)稱為開(kai)啟(qi)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li);系(xi)統壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)降低,壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)復位切(qie)斷電(dian)(dian)(dian)信(xin)號的(de)(de)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)稱為閉合(he)(he)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)。開(kai)啟(qi)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)與(yu)閉合(he)(he)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)的(de)(de)差值(zhi)(zhi)稱為壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)(de)靈(ling)敏(min)度。差值(zhi)(zhi)小則(ze)靈(ling)敏(min)度高(gao)。為避免系(xi)統壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)波(bo)動時(shi)(shi)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)時(shi)(shi)通(tong)時(shi)(shi)斷,要求開(kai)啟(qi)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)與(yu)閉合(he)(he)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)有(you)一定的(de)(de)差值(zhi)(zhi),此(ci)差值(zhi)(zhi)若可調,則(ze)稱為通(tong)斷調節(jie)區間。
(3)升壓(ya)或降(jiang)壓(ya)動(dong)作時間(jian)
壓(ya)(ya)力(li)(li)(li)繼電(dian)(dian)器入口側壓(ya)(ya)力(li)(li)(li)由卸(xie)荷壓(ya)(ya)力(li)(li)(li)升(sheng)至調定壓(ya)(ya)力(li)(li)(li)時(shi),微動(dong)開關觸點(dian)接(jie)通發(fa)出電(dian)(dian)信號(hao)的時(shi)間(jian)稱為(wei)升(sheng)壓(ya)(ya)動(dong)作時(shi)間(jian),反之,壓(ya)(ya)力(li)(li)(li)下(xia)降(jiang),觸點(dian)斷開發(fa)出斷電(dian)(dian)信號(hao)的時(shi)間(jian)稱為(wei)降(jiang)壓(ya)(ya)動(dong)作時(shi)間(jian)。
(4)重(zhong)復精度
在一定的調定壓力(li)(li)下,多(duo)次升壓(或降壓)過(guo)程中,開啟壓力(li)(li)或閉合壓力(li)(li)本身(shen)的差(cha)值稱為(wei)重復精(jing)度(du),差(cha)值小則重復精(jing)度(du)高。
