ATOS壓力繼電器是液壓系統(tong)中當流(liu)體壓力達(da)到預定(ding)值時(shi),使(shi)(shi)電(dian)接點(dian)動(dong)作(zuo)(zuo)的(de)(de)元(yuan)(yuan)件(jian)。是利用液體的(de)(de)壓力來啟(qi)閉電(dian)氣(qi)觸點(dian)的(de)(de)液壓電(dian)氣(qi)轉換元(yuan)(yuan)件(jian)。當系統(tong)壓力達(da)到壓力繼電(dian)器的(de)(de)調定(ding)值時(shi),發出電(dian)信(xin)號,使(shi)(shi)電(dian)氣(qi)元(yuan)(yuan)件(jian)(如電(dian)磁(ci)鐵、電(dian)機(ji)、時(shi)間繼電(dian)器、電(dian)磁(ci)離合器等(deng))動(dong)作(zuo)(zuo),使(shi)(shi)油路卸壓、換向,執(zhi)行(xing)元(yuan)(yuan)件(jian)實現順序動(dong)作(zuo)(zuo),或關閉電(dian)動(dong)機(ji)使(shi)(shi)系統(tong)停止工(gong)作(zuo)(zuo),起(qi)安(an)全保護作(zuo)(zuo)用等(deng)。 作為控制元件,概括起來,繼(ji)電器有如下(xia)幾(ji)種作用: 1)、擴大控制范圍:例如(ru),多觸(chu)點繼電器控制信號達到某一定值(zhi)時,可以(yi)按觸(chu)點組的不(bu)同形式,同時換接(jie)、開斷、接(jie)通多路(lu)電路(lu)。 2)、放大:例如,靈敏型繼電(dian)器、中間繼電(dian)器等,用一個很微小的控制(zhi)量,可(ke)以(yi)控制(zhi)很大功(gong)率的電(dian)路。 3)、綜合信(xin)號:例(li)如,當多個控制信(xin)號按規定的形(xing)式輸(shu)入多繞組(zu)繼電器時,經過比較(jiao)綜合,達到預定的控制效果。 4)、自(zi)(zi)動、遙控(kong)、監測:例如,自(zi)(zi)動裝置(zhi)上的繼(ji)電器(qi)與其他電器(qi)一起,可以(yi)組成程序控(kong)制線路,從而實現自(zi)(zi)動化運行。 ATOS阿托斯繼電器的觸點有三種基本形式: 1、動合(he)型(xing)(常開)(H型(xing))線圈不通(tong)電時兩觸點是斷開的(de),通(tong)電后(hou),兩個觸點就閉合(he)。以合(he)字的(de)拼音字頭“H”表示。 2、動斷型(xing)(常閉(bi))(D型(xing))線圈不通電時兩觸點是(shi)閉(bi)合的,通電后兩個觸點就斷開。用斷字的拼音(yin)字頭“D”表示。 3、轉換(huan)型(Z型)這是觸(chu)點(dian)(dian)(dian)組型。這種觸(chu)點(dian)(dian)(dian)組共有三(san)個(ge)觸(chu)點(dian)(dian)(dian),即中間是動(dong)觸(chu)點(dian)(dian)(dian),上下各一(yi)個(ge)靜觸(chu)點(dian)(dian)(dian)。線圈不通電時,動(dong)觸(chu)點(dian)(dian)(dian)和(he)其中一(yi)個(ge)靜觸(chu)點(dian)(dian)(dian)斷(duan)(duan)開(kai)(kai)(kai)和(he)另一(yi)個(ge)閉(bi)合(he),線圈通電后,動(dong)觸(chu)點(dian)(dian)(dian)就移(yi)動(dong),使原來斷(duan)(duan)開(kai)(kai)(kai)的成(cheng)閉(bi)合(he),原來閉(bi)合(he)的成(cheng)斷(duan)(duan)開(kai)(kai)(kai)狀態,達(da)到(dao)轉換(huan)的目的。這樣的觸(chu)點(dian)(dian)(dian)組稱為轉換(huan)觸(chu)點(dian)(dian)(dian)。用“轉”字的拼音字頭(tou)“z”表示。 ATOS壓力繼電器正確使用方法: 首先,用于安全保護(hu)時,將壓(ya)(ya)(ya)力(li)(li)繼(ji)電(dian)(dian)(dian)器設置在(zai)夾(jia)緊(jin)液(ye)壓(ya)(ya)(ya)缸的(de)一端(duan),液(ye)壓(ya)(ya)(ya)泵啟動(dong)后,首先將工(gong)件夾(jia)緊(jin),此時夾(jia)緊(jin)液(ye)壓(ya)(ya)(ya)缸的(de)右腔壓(ya)(ya)(ya)力(li)(li)升(sheng)高(gao),當升(sheng)高(gao)到壓(ya)(ya)(ya)力(li)(li)繼(ji)電(dian)(dian)(dian)器的(de)調定值時,壓(ya)(ya)(ya)力(li)(li)繼(ji)電(dian)(dian)(dian)器動(dong)作,發出電(dian)(dian)(dian)信(xin)號使(shi)2YA通電(dian)(dian)(dian),于是切(qie)削(xue)液(ye)壓(ya)(ya)(ya)缸進刀切(qie)削(xue)。在(zai)加工(gong)期間,壓(ya)(ya)(ya)力(li)(li)繼(ji)電(dian)(dian)(dian)器微動(dong)開關的(de)常開觸(chu)點始終閉合。若工(gong)件沒有夾(jia)緊(jin),壓(ya)(ya)(ya)力(li)(li)繼(ji)電(dian)(dian)(dian)器2斷(duan)開,于是2YA斷(duan)電(dian)(dian)(dian),切(qie)削(xue)液(ye)壓(ya)(ya)(ya)缸立即停(ting)止進刀,從而(er)避免工(gong)件未(wei)夾(jia)緊(jin)被切(qie)削(xue)而(er)出事故。 其實(shi)用(yong)于控制執行(xing)元件的順序動作時,液(ye)壓(ya)泵啟動后,首先2YA通(tong)電,液(ye)壓(ya)缸左腔進油,推(tui)動活塞方(fang)向(xiang)右移。當碰到(dao)限位(wei)器(或死擋鐵)后,系(xi)統壓(ya)力升高,壓(ya)力繼(ji)電器發出電信(xin)號,使1YA通(tong)電 ,高壓油進入液壓缸(gang)(gang)的左腔(qiang),推動活塞右移(yi)(yi)。這時若(ruo)3YA也通(tong)電,液壓缸(gang)(gang)的活塞快(kuai)速(su)右移(yi)(yi);若(ruo)3YA斷電,則液壓缸(gang)(gang)的活塞慢(man)速(su)右移(yi)(yi),其慢(man)速(su)運動速(su)度由節(jie)流閥調(diao)節(jie)。 再(zai)次(ci)用于(yu)液(ye)壓(ya)(ya)泵卸荷時,壓(ya)(ya)力繼電器不是控制液(ye)壓(ya)(ya)泵停止轉動,而是控制二(er)位二(er)通電磁閥,將液(ye)壓(ya)(ya)泵5輸(shu)出的壓(ya)(ya)力油流回油箱(xiang),使其卸荷。 最后(hou)用(yong)于液(ye)壓(ya)(ya)泵(beng)(beng)的啟閉時(shi),有(you)兩個液(ye)壓(ya)(ya)泵(beng)(beng),高壓(ya)(ya)小流量泵(beng)(beng),低(di)壓(ya)(ya)大流量泵(beng)(beng)。當(dang)活(huo)塞(sai)快(kuai)速下降時(shi),兩泵(beng)(beng)同(tong)時(shi)輸出壓(ya)(ya)力(li)油。當(dang)液(ye)壓(ya)(ya)缸(gang)活(huo)塞(sai)桿抵住工件開(kai)始(shi)加(jia)壓(ya)(ya)時(shi),壓(ya)(ya)力(li)繼電(dian)器在(zai)(zai)壓(ya)(ya)力(li)油作用(yong)下發(fa)出動(dong)作,觸(chu)動(dong)微動(dong)開(kai)關,將常閉觸(chu)點斷開(kai),使(shi)液(ye)壓(ya)(ya)泵(beng)(beng)停轉。在(zai)(zai)加(jia)工過程中減慢液(ye)壓(ya)(ya)缸(gang)的速度(du),同(tong)時(shi)減少動(dong)力(li)消耗。 ATOS阿托斯繼電器*現貨型號: MAP-080 20 MAP-640 20 MAP-160/20 SMAP-32010S QV-06/24/K 60 QV-06/6 QV-06/6/V 60 QV-10/2 QV-10/2/V 53 QV-10/3/K QV-20/2 QV-20/2/K AGMZO-A-10/315/Y AGMZO-A-20/210 AGMZO-A-20/315 AGMZO-A-20/315/Y AGMZO-A-20/210 AGMZO-A-20/315 AGMZO-A-20/315/Y AGMZO-A-32/315 DPZO-AE-173-05/DGI DPZO-AE-173-L5/GI 10 DPZO-AE-271-D5/I 30 DPZO-AE-271-L5 30 DPZO-AE-271-S5 30 DPZO-AE-271-S5/D DKZOR-T-151-L5 DKZOR-T-151-L5/Y DKZOR-T-153-L5 DKZOR-T-171-D5 DKZOR-T-171-L5 DKZOR-T-171-S5 此信息版權歸上海維特銳所有,如需了解更多詳情,請點擊:意大利ATOS阿托斯 |
