 意大利(li)ATOS阿托斯壓(ya)(ya)力繼電(dian)(dian)(dian)器(qi)(qi)是利(li)用(yong)液(ye)體的壓(ya)(ya)力來啟閉(bi)電(dian)(dian)(dian)氣(qi)(qi)觸點的液(ye)壓(ya)(ya)電(dian)(dian)(dian)氣(qi)(qi)轉換元件。當系(xi)統壓(ya)(ya)力達到壓(ya)(ya)力繼電(dian)(dian)(dian)器(qi)(qi)的調定值時,發出電(dian)(dian)(dian)信號(hao),使電(dian)(dian)(dian)氣(qi)(qi)元件(如電(dian)(dian)(dian)磁(ci)(ci)鐵、電(dian)(dian)(dian)機(ji)、時間繼電(dian)(dian)(dian)器(qi)(qi)、電(dian)(dian)(dian)磁(ci)(ci)離合(he)器(qi)(qi)等(deng))動作(zuo)(zuo),使油路卸(xie)壓(ya)(ya)、換向,執(zhi)行元件實現順序動作(zuo)(zuo),或關(guan)閉(bi)電(dian)(dian)(dian)動機(ji)使系(xi)統停止工作(zuo)(zuo),起安全(quan)保護(hu)作(zuo)(zuo)用(yong)等(deng)。

   首先(xian)用于(yu)安全保護(hu)時,將(jiang)意大利(li)ATOS阿托斯壓(ya)(ya)力(li)繼電(dian)器(qi)設置在夾緊(jin)(jin)(jin)液壓(ya)(ya)缸的(de)一端,液壓(ya)(ya)泵啟動后,首先(xian)將(jiang)工件夾緊(jin)(jin)(jin),此時夾緊(jin)(jin)(jin)液壓(ya)(ya)缸的(de)右(you)腔(qiang)壓(ya)(ya)力(li)升(sheng)高,當升(sheng)高到意大利(li)ATOS阿托斯壓(ya)(ya)力(li)繼電(dian)器(qi)的(de)調定值時,壓(ya)(ya)力(li)繼電(dian)器(qi)動作,發出電(dian)信號(hao)使2YA通(tong)電(dian),于(yu)是切(qie)削(xue)(xue)液壓(ya)(ya)缸進刀切(qie)削(xue)(xue)。在加工期間,意大利(li)ATOS阿托斯壓(ya)(ya)力(li)繼電(dian)器(qi)微(wei)動開(kai)關的(de)常(chang)開(kai)觸點(dian)始終閉合。若(ruo)工件沒有(you)夾緊(jin)(jin)(jin),壓(ya)(ya)力(li)繼電(dian)器(qi)2斷(duan)開(kai),于(yu)是2YA斷(duan)電(dian),切(qie)削(xue)(xue)液壓(ya)(ya)缸立(li)即停(ting)止(zhi)進刀,從而避(bi)免工件未(wei)夾緊(jin)(jin)(jin)被切(qie)削(xue)(xue)而出事故。

   其實用于控(kong)制(zhi)執行(xing)元件的順序動(dong)作時(shi)(shi),液(ye)(ye)壓(ya)泵(beng)啟動(dong)后,首(shou)先2YA通電(dian)(dian),液(ye)(ye)壓(ya)缸左腔(qiang)進油,推動(dong)活(huo)塞方向(xiang)右(you)移(yi)(yi)。當碰到限位器(或死擋鐵)后,系統壓(ya)力升高,壓(ya)力繼(ji)電(dian)(dian)器發出電(dian)(dian)信號(hao),使1YA通電(dian)(dian),高壓(ya)油進入液(ye)(ye)壓(ya)缸的左腔(qiang),推動(dong)活(huo)塞右(you)移(yi)(yi)。這時(shi)(shi)若3YA也通電(dian)(dian),液(ye)(ye)壓(ya)缸的活(huo)塞快速(su)(su)右(you)移(yi)(yi);若3YA斷(duan)電(dian)(dian),則液(ye)(ye)壓(ya)缸的活(huo)塞慢速(su)(su)右(you)移(yi)(yi),其慢速(su)(su)運動(dong)速(su)(su)度由節流閥調節。

   再次用于(yu)液壓(ya)泵(beng)(beng)卸荷時,意大利ATOS阿托(tuo)斯壓(ya)力繼(ji)電(dian)器(qi)不是控制液壓(ya)泵(beng)(beng)停(ting)止轉動,而是控制二位二通(tong)電(dian)磁閥,將(jiang)液壓(ya)泵(beng)(beng)5輸(shu)出的壓(ya)力油流回油箱,使其(qi)卸荷。

   用于液(ye)(ye)壓(ya)泵(beng)的啟閉時(shi),有兩個液(ye)(ye)壓(ya)泵(beng),高壓(ya)小流(liu)量泵(beng),低壓(ya)大(da)(da)流(liu)量泵(beng)。當活(huo)塞快速下降(jiang)時(shi),兩泵(beng)同時(shi)輸(shu)出(chu)壓(ya)力(li)油。當液(ye)(ye)壓(ya)缸活(huo)塞桿抵(di)住工(gong)件開(kai)始加壓(ya)時(shi),意(yi)大(da)(da)利ATOS阿托斯(si)壓(ya)力(li)繼電器在(zai)壓(ya)力(li)油作(zuo)用下發出(chu)動(dong)作(zuo),觸(chu)動(dong)微(wei)動(dong)開(kai)關,將常閉觸(chu)點(dian)斷開(kai),使(shi)液(ye)(ye)壓(ya)泵(beng)停轉(zhuan)。在(zai)加工(gong)過程中(zhong)減慢液(ye)(ye)壓(ya)缸的速度,同時(shi)減少動(dong)力(li)消耗。

  意大利ATOS阿(a)托(tuo)斯壓力繼電器的工作(zuo)原理:

   壓力繼(ji)電(dian)器有柱(zhu)塞式(shi)、膜(mo)片式(shi)、彈(dan)簧管式(shi)和波(bo)紋管式(shi)四種結構形式(shi)。下面對(dui)柱(zhu)塞式(shi)壓力繼(ji)電(dian)器的工作(zuo)原理作(zuo)一介紹:

   當從繼電(dian)器下端(duan)進(jin)油口3進(jin)入(ru)的液體(ti)壓力達到調(diao)定壓力值時,推(tui)(tui)動(dong)(dong)柱(zhu)塞2上移(yi),此位移(yi)通過杠桿放大后(hou)推(tui)(tui)動(dong)(dong)微動(dong)(dong)開(kai)關4動(dong)(dong)作。改(gai)變彈簧1的壓縮量,可以調(diao)節繼電(dian)器的動(dong)(dong)作壓力。

  應用(yong)場合:用(yong)于安全保護、控制執行(xing)元件的(de)順(shun)序動作、用(yong)于泵(beng)的(de)啟閉、用(yong)于泵(beng)的(de)卸荷。

   意大利ATOS阿托斯壓力繼(ji)電器的(de)主要性能有(you)以下幾個方面(mian)。

  (1)調壓范圍

  壓(ya)力繼(ji)電(dian)器能夠發出電(dian)信號的低工作壓(ya)力和高工作壓(ya)力的范圍稱為調壓(ya)范圍。

  (2)靈敏(min)度與通(tong)斷調節區間

  系(xi)統(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)升高到壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)繼(ji)電(dian)器(qi)(qi)(qi)的(de)調(diao)定值(zhi)時,壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)繼(ji)電(dian)器(qi)(qi)(qi)動(dong)作接通(tong)(tong)電(dian)信號的(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)稱為(wei)開啟(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li);系(xi)統(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)降低,壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)繼(ji)電(dian)器(qi)(qi)(qi)復(fu)位切斷(duan)電(dian)信號的(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)稱為(wei)閉(bi)合(he)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)。開啟(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)與閉(bi)合(he)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)的(de)差值(zhi)稱為(wei)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)繼(ji)電(dian)器(qi)(qi)(qi)的(de)靈敏(min)度。差值(zhi)小則(ze)靈敏(min)度高。為(wei)避(bi)免系(xi)統(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)波動(dong)時壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)繼(ji)電(dian)器(qi)(qi)(qi)時通(tong)(tong)時斷(duan),要求(qiu)開啟(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)與閉(bi)合(he)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)有一定的(de)差值(zhi),此差值(zhi)若可(ke)調(diao),則(ze)稱為(wei)通(tong)(tong)斷(duan)調(diao)節(jie)區間(jian)。

  (3)升壓或降壓動(dong)作時間

  壓力繼(ji)電(dian)器(qi)入(ru)口側壓力由卸荷(he)壓力升至調定(ding)壓力時(shi),微(wei)動(dong)開(kai)(kai)關觸點接通發(fa)出(chu)電(dian)信號的(de)時(shi)間(jian)稱為(wei)升壓動(dong)作時(shi)間(jian),反之,壓力下降,觸點斷開(kai)(kai)發(fa)出(chu)斷電(dian)信號的(de)時(shi)間(jian)稱為(wei)降壓動(dong)作時(shi)間(jian)。
