ATOS原裝產品壓力繼電器上海維特銳價格好,種類齊全,原廠供應貨源品質安全放心,15年老公司信譽保證,假一罰十。 ATOS原裝產品壓力繼電器也可定(ding)義為將壓(ya)(ya)力轉換(huan)成電(dian)(dian)信號的(de)液壓(ya)(ya)元(yuan)器件(jian),客戶根據自身的(de)壓(ya)(ya)力設計需要,通過調節(jie)壓(ya)(ya)力繼(ji)電(dian)(dian)器,實現(xian)在某一設定(ding)的(de)壓(ya)(ya)力時(shi)(shi),輸(shu)出(chu)一個電(dian)(dian)信號的(de)功能(neng)。當系(xi)統(tong)壓(ya)(ya)力達到壓(ya)(ya)力繼(ji)電(dian)(dian)器的(de)調定(ding)值時(shi)(shi),發(fa)出(chu)電(dian)(dian)信號,使(shi)電(dian)(dian)氣(qi)元(yuan)件(jian)(如電(dian)(dian)磁鐵、電(dian)(dian)機、時(shi)(shi)間(jian)繼(ji)電(dian)(dian)器、電(dian)(dian)磁離合器等(deng))動作(zuo)(zuo),使(shi)油(you)路卸壓(ya)(ya)、換(huan)向,執行元(yuan)件(jian)實現(xian)順序動作(zuo)(zuo),或關閉電(dian)(dian)動機使(shi)系(xi)統(tong)停止工(gong)作(zuo)(zuo),起安全(quan)保(bao)護作(zuo)(zuo)用等(deng)。 使用方法: 首(shou)先(xian)用于(yu)(yu)安全保(bao)護時,將壓(ya)(ya)(ya)(ya)(ya)力(li)繼電(dian)(dian)器(qi)(qi)設置在(zai)(zai)夾(jia)(jia)(jia)緊(jin)液(ye)壓(ya)(ya)(ya)(ya)(ya)缸(gang)的(de)(de)一端(duan),液(ye)壓(ya)(ya)(ya)(ya)(ya)泵啟動(dong)后(hou),首(shou)先(xian)將工件夾(jia)(jia)(jia)緊(jin),此(ci)時夾(jia)(jia)(jia)緊(jin)液(ye)壓(ya)(ya)(ya)(ya)(ya)缸(gang)的(de)(de)右腔(qiang)壓(ya)(ya)(ya)(ya)(ya)力(li)升高,當升高到(dao)壓(ya)(ya)(ya)(ya)(ya)力(li)繼電(dian)(dian)器(qi)(qi)的(de)(de)調定值時,壓(ya)(ya)(ya)(ya)(ya)力(li)繼電(dian)(dian)器(qi)(qi)動(dong)作,發出電(dian)(dian)信(xin)號使2YA通電(dian)(dian),于(yu)(yu)是(shi)切削(xue)液(ye)壓(ya)(ya)(ya)(ya)(ya)缸(gang)進刀切削(xue)。在(zai)(zai)加工期間,壓(ya)(ya)(ya)(ya)(ya)力(li)繼電(dian)(dian)器(qi)(qi)微動(dong)開關的(de)(de)常(chang)開觸點始終閉合。若工件沒有(you)夾(jia)(jia)(jia)緊(jin),壓(ya)(ya)(ya)(ya)(ya)力(li)繼電(dian)(dian)器(qi)(qi)2斷(duan)(duan)開,于(yu)(yu)是(shi)2YA斷(duan)(duan)電(dian)(dian),切削(xue)液(ye)壓(ya)(ya)(ya)(ya)(ya)缸(gang)立即停止進刀,從而避(bi)免工件未夾(jia)(jia)(jia)緊(jin)被切削(xue)而出事故。 其實(shi)用于控制執行元件的順序動(dong)(dong)作(zuo)時,液壓泵(beng)啟動(dong)(dong)后(hou)(hou),首先(xian)2YA通(tong)電,液壓缸(gang)左(zuo)腔進油,推動(dong)(dong)活塞方向右(you)移。當(dang)碰到限位器(qi)(或死(si)擋鐵)后(hou)(hou),系統壓力升(sheng)高,壓力繼電器(qi)發出(chu)電信號(hao),使1YA通(tong)電 ,高壓油進入液壓缸的(de)左(zuo)腔(qiang),推動(dong)活(huo)塞右移(yi)(yi)(yi)。這(zhe)時若(ruo)3YA也通電,液壓缸的(de)活(huo)塞快速右移(yi)(yi)(yi);若(ruo)3YA斷電,則液壓缸的(de)活(huo)塞慢速右移(yi)(yi)(yi),其慢速運(yun)動(dong)速度(du)由(you)節流閥(fa)調節。 再(zai)次用(yong)于液(ye)(ye)壓泵(beng)卸荷(he)時,壓力(li)繼電器不是(shi)控(kong)制(zhi)液(ye)(ye)壓泵(beng)停(ting)止轉動,而是(shi)控(kong)制(zhi)二位二通電磁閥,將液(ye)(ye)壓泵(beng)5輸出的壓力(li)油(you)流回油(you)箱(xiang),使其卸荷(he)。 最后用(yong)于液(ye)(ye)壓(ya)泵的啟閉(bi)時(shi),有(you)兩個液(ye)(ye)壓(ya)泵,高壓(ya)小流量泵,低(di)壓(ya)大(da)流量泵。當活(huo)塞快速(su)下降時(shi),兩泵同(tong)時(shi)輸出壓(ya)力(li)(li)油(you)。當液(ye)(ye)壓(ya)缸(gang)活(huo)塞桿抵住工(gong)件開始加壓(ya)時(shi),壓(ya)力(li)(li)繼電器在壓(ya)力(li)(li)油(you)作用(yong)下發出動(dong)(dong)作,觸動(dong)(dong)微動(dong)(dong)開關,將(jiang)常(chang)閉(bi)觸點斷開,使液(ye)(ye)壓(ya)泵停轉。在加工(gong)過(guo)程(cheng)中減慢液(ye)(ye)壓(ya)缸(gang)的速(su)度,同(tong)時(shi)減少動(dong)(dong)力(li)(li)消耗。 ATOS原裝產(chan)品壓力繼電器主要測試項目: (1)動作值。繼電器動作時所需電壓值。 (2)觸點(dian)接(jie)觸電(dian)(dian)阻(zu)。觸電(dian)(dian)閉(bi)合時,兩觸頭(tou)之間的電(dian)(dian)阻(zu)值。 (3)機械壽命。機械部分在不損壞(huai)的情況(kuang)下,繼電(dian)器反復開關(guan)動作次數。 (4)觸(chu)(chu)點(dian)接觸(chu)(chu)電(dian)壓。觸(chu)(chu)電(dian)閉合(he)時,觸(chu)(chu)電(dian)回路中施加一定負載電(dian)流(liu),觸(chu)(chu)點(dian)間電(dian)壓值。 (5)電壽命。繼電器驅動線圈(quan)兩端施加額(e)定電壓,觸(chu)點回路中施加額(e)定阻性負載時(shi),每小時(shi)循環小于(yu)300次(ci)、占空比1∶4條件下(xia),繼電器的可靠動作次(ci)數。 (6)過負荷能(neng)力。繼(ji)電器驅動(dong)線圈(quan)兩(liang)端(duan)施加(jia)(jia)額(e)(e)定(ding)(ding)電壓(ya),觸點(dian)回路中(zhong)施加(jia)(jia)1.5倍額(e)(e)定(ding)(ding)負載時,動(dong)作(zuo)頻率(lv)(10±1)次(ci)/分(fen)條件下(xia),繼(ji)電器可靠動(dong)作(zuo)次(ci)數。 ATOS原裝產品壓力繼電(dian)器(qi)*型號: MAP-640 20 MAP-160/20 SMAP-32010S E-ME-AC-01F 20 E-ME-AC-01F 20 /1 E-ME-AC-01F 20 /2 E-ME-AC-01F 20 /3 E-ME-AC-01F 20 /4 E-ME-AC-01F 20 /6 E-ME-AC-01F 20 /A1 E-ME-AC-01F 20 /A2 E-ME-AC-05F/I 20 /3 E-ME-AC-05F/I 20 /4 E-ME-AC-05F/RR 20 E-ME-L-01H 40 /DL27SB E-ME-L-01H 40 /DL27SB E-ME-L-01H 40 /DL27SB E-ME-L-01H 40 /DL35SB MAP-320E MAP-080/E 20 MAP-080 20 MAP-640 20 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 |
