討論BURKERT電磁閥幾位幾通的適用(yong)環(huan)境(jing)

德國BURKERT電(dian)(dian)磁(ci)閥(fa)一般由(you)基準(zhun)源(yuan)、冷(leng)端(duan)補償、放大(da)單元、線性(xing)(xing)(xing)化處理(li)、V/I轉換、斷偶處理(li)、反(fan)接保(bao)(bao)護(hu)(hu)(hu)、限(xian)流(liu)(liu)保(bao)(bao)護(hu)(hu)(hu)等電(dian)(dian)路(lu)單元組成。它(ta)是(shi)將熱(re)電(dian)(dian)偶產生的(de)(de)熱(re)電(dian)(dian)勢(shi)經(jing)冷(leng)端(duan)補償放大(da)后，再帽由(you)線性(xing)(xing)(xing)電(dian)(dian)路(lu)消除熱(re)電(dian)(dian)勢(shi)與(yu)溫度的(de)(de)非線性(xing)(xing)(xing)誤差(cha)，zui后放大(da)轉換為4～20mA電(dian)(dian)流(liu)(liu)輸(shu)(shu)出(chu)信(xin)號(hao)(hao)。為防(fang)止熱(re)電(dian)(dian)偶測量中(zhong)由(you)于(yu)電(dian)(dian)偶斷絲而使(shi)(shi)控溫失效造成事故，傳(chuan)感(gan)器中(zhong)還設有(you)(you)斷電(dian)(dian)保(bao)(bao)護(hu)(hu)(hu)電(dian)(dian)路(lu)。當熱(re)電(dian)(dian)偶斷絲或(huo)接解不良時，傳(chuan)感(gan)器會(hui)輸(shu)(shu)出(chu)zui大(da)值（28mA）以使(shi)(shi)儀表切斷電(dian)(dian)源(yuan)。具有(you)(you)結構簡單、節省引(yin)線、輸(shu)(shu)出(chu)信(xin)號(hao)(hao)大(da)、抗干擾(rao)能力強、線性(xing)(xing)(xing)好(hao)、顯(xian)示儀表簡單、固體模(mo)塊(kuai)抗震防(fang)潮、有(you)(you)反(fan)接保(bao)(bao)護(hu)(hu)(hu)和(he)限(xian)流(liu)(liu)保(bao)(bao)護(hu)(hu)(hu)、工作可靠等優點。BURKERT電(dian)(dian)磁(ci)閥(fa)的(de)(de)輸(shu)(shu)出(chu)為統一的(de)(de) 4～20mA信(xin)號(hao)(hao)；可與(yu)微(wei)機系統或(huo)其它(ta)常規儀表匹配使(shi)(shi)用(yong)。也可用(yong)戶要求做成防(fang)爆型或(huo)防(fang)火型測量儀表。

德國(guo)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)在(zai)氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)（或液路(lu)(lu)(lu)）上來說，兩位三(san)通(tong)(tong)(tong)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)具有1個(ge)(ge)(ge)進(jin)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)（接(jie)(jie)進(jin)氣(qi)(qi)(qi)(qi)(qi)氣(qi)(qi)(qi)(qi)(qi)源）、1個(ge)(ge)(ge)出(chu)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)（提(ti)供(gong)給(gei)(gei)目(mu)標設(she)備(bei)氣(qi)(qi)(qi)(qi)(qi)源）、1個(ge)(ge)(ge)排(pai)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)。 兩位五通(tong)(tong)(tong)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)具有1個(ge)(ge)(ge)進(jin)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)（接(jie)(jie)進(jin)氣(qi)(qi)(qi)(qi)(qi)氣(qi)(qi)(qi)(qi)(qi)源）、1個(ge)(ge)(ge)正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)和1個(ge)(ge)(ge)反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)（分別(bie)提(ti)供(gong)給(gei)(gei)目(mu)標設(she)備(bei)的(de)一正(zheng)(zheng)一反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)的(de)氣(qi)(qi)(qi)(qi)(qi)源）、1個(ge)(ge)(ge)正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)排(pai)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)和1個(ge)(ge)(ge)反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)排(pai)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)（安裝消聲器）。 對于小型(xing)自動(dong)(dong)控(kong)(kong)制(zhi)設(she)備(bei)，氣(qi)(qi)(qi)(qi)(qi)管(guan)一般選(xuan)用8~12mm的(de)工業膠(jiao)氣(qi)(qi)(qi)(qi)(qi)管(guan)。線(xian)(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)壓等(deng)級一般采(cai)用DC24V、AC220V等(deng)。 兩位三(san)通(tong)(tong)(tong)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)分為常(chang)閉(bi)型(xing)和常(chang)開型(xing)兩種，常(chang)閉(bi)型(xing)指線(xian)(xian)(xian)圈(quan)(quan)(quan)沒(mei)(mei)通(tong)(tong)(tong)電(dian)(dian)時氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)是(shi)斷(duan)的(de)，常(chang)開型(xing)指線(xian)(xian)(xian)圈(quan)(quan)(quan)沒(mei)(mei)通(tong)(tong)(tong)電(dian)(dian)時氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)是(shi)通(tong)(tong)(tong)的(de)。 常(chang)閉(bi)型(xing)兩位三(san)通(tong)(tong)(tong)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)原(yuan)理：給(gei)(gei)線(xian)(xian)(xian)圈(quan)(quan)(quan)通(tong)(tong)(tong)電(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)接(jie)(jie)通(tong)(tong)(tong)，線(xian)(xian)(xian)圈(quan)(quan)(quan)一旦(dan)(dan)斷(duan)電(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)就會斷(duan)開，這(zhe)相當于“點(dian)動(dong)(dong)”。 常(chang)開型(xing)兩位三(san)通(tong)(tong)(tong)單電(dian)(dian)控(kong)(kong)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)原(yuan)理：給(gei)(gei)線(xian)(xian)(xian)圈(quan)(quan)(quan)通(tong)(tong)(tong)電(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)斷(duan)開，線(xian)(xian)(xian)圈(quan)(quan)(quan)一旦(dan)(dan)斷(duan)電(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)就會接(jie)(jie)通(tong)(tong)(tong)，這(zhe)也(ye)是(shi)“點(dian)動(dong)(dong)”。 兩位五通(tong)(tong)(tong)雙電(dian)(dian)控(kong)(kong)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)原(yuan)理：給(gei)(gei)正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)通(tong)(tong)(tong)電(dian)(dian)，則(ze)正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)接(jie)(jie)通(tong)(tong)(tong)（正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)有氣(qi)(qi)(qi)(qi)(qi)），即(ji)使給(gei)(gei)正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)斷(duan)電(dian)(dian)后正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)仍然是(shi)接(jie)(jie)通(tong)(tong)(tong)的(de)，將會一直維持到給(gei)(gei)反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)通(tong)(tong)(tong)電(dian)(dian)為止。 給(gei)(gei)反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)通(tong)(tong)(tong)電(dian)(dian)，則(ze)反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)接(jie)(jie)通(tong)(tong)(tong)（反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)(qi)(qi)孔(kong)(kong)有氣(qi)(qi)(qi)(qi)(qi)），即(ji)使給(gei)(gei)反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)斷(duan)電(dian)(dian)后反(fan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)氣(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(lu)仍然是(shi)接(jie)(jie)通(tong)(tong)(tong)的(de)，將會一直維持到給(gei)(gei)正(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)通(tong)(tong)(tong)電(dian)(dian)為止。這(zhe)相當于“自鎖”。 基于兩位五通(tong)(tong)(tong)雙電(dian)(dian)控(kong)(kong)BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)這(zhe)種特性，在(zai)設(she)計機電(dian)(dian)控(kong)(kong)制(zhi)回路(lu)(lu)(lu)或編制(zhi)PLC程序的(de)時候(hou)，可以讓BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)線(xian)(xian)(xian)圈(quan)(quan)(quan)動(dong)(dong)作(zuo)(zuo)(zuo)(zuo)1~2秒就可以了，這(zhe)樣可以保護BURKERT電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)線(xian)(xian)(xian)圈(quan)(quan)(quan)不(bu)容易(yi)損壞。
