常(chang)閉型ASCO電(dian)磁(ci)閥(fa)一直通電(dian)會有什(shen)么影響

　　一、常閉(bi)型(xing)ASCO電(dian)磁閥原理和流通狀態(tai)

　　常閉(bi)型電(dian)磁閥(fa)(fa)是指在沒(mei)有(you)外部(bu)電(dian)源作(zuo)用(yong)時，閥(fa)(fa)門(men)處于關閉(bi)狀態(tai)的電(dian)磁閥(fa)(fa)。它的工作(zuo)原理(li)是通(tong)(tong)過通(tong)(tong)電(dian)使(shi)(shi)電(dian)磁鐵(tie)產生(sheng)磁場，磁場作(zuo)用(yong)下(xia)使(shi)(shi)得(de)閥(fa)(fa)門(men)開啟，斷電(dian)則閥(fa)(fa)門(men)關閉(bi)。因此，常閉(bi)型電(dian)磁閥(fa)(fa)的流通(tong)(tong)狀態(tai)是在通(tong)(tong)電(dian)狀態(tai)下(xia)開啟，斷電(dian)狀態(tai)下(xia)關閉(bi)。

　　二、常閉(bi)型ASCO電(dian)磁閥一直(zhi)通電(dian)的影響

　　如果常閉型ASCO電(dian)磁閥一直通電(dian)，則電(dian)磁鐵(tie)會(hui)(hui)一直處(chu)于通電(dian)狀態，而閥門也會(hui)(hui)一直處(chu)于打開狀態。這種情況下可能會(hui)(hui)帶(dai)來以下影響(xiang)：

　　1. 電磁(ci)鐵發熱(re)

　　常閉型電(dian)磁(ci)(ci)閥一(yi)直通電(dian)會導致電(dian)磁(ci)(ci)鐵(tie)(tie)長時(shi)間工作，電(dian)磁(ci)(ci)鐵(tie)(tie)發(fa)熱，甚(shen)至會燒壞電(dian)磁(ci)(ci)鐵(tie)(tie)。

　　2. 流量大

　　ASCO電(dian)磁閥一直通電(dian)會導致閥門一直開啟(qi)，流量會持(chi)續(xu)增大(da)，造成設備無法正常(chang)工(gong)作或工(gong)作效果(guo)不佳。

　　3. 能耗大

　　長時間(jian)進行電(dian)磁(ci)鐵通(tong)電(dian)會造成能(neng)源浪費，電(dian)磁(ci)鐵易(yi)損壞更會導致頻繁更換的費用增加。

　　因此(ci)，對(dui)于常(chang)閉型(xing)電(dian)(dian)(dian)磁閥來說(shuo)，應該嚴格按照其(qi)設(she)計的電(dian)(dian)(dian)氣(qi)控制系(xi)統(tong)使(shi)用，避免(mian)長時間通(tong)電(dian)(dian)(dian)或者(zhe)斷電(dian)(dian)(dian)過(guo)久(jiu)。若出現(xian)常(chang)閉型(xing)電(dian)(dian)(dian)磁閥需要持續開(kai)啟(qi)(qi)的情況，建(jian)議使(shi)用常(chang)開(kai)型(xing)電(dian)(dian)(dian)磁閥（休閑通(tong)電(dian)(dian)(dian)為(wei)關閉狀態，切斷電(dian)(dian)(dian)源后為(wei)開(kai)啟(qi)(qi)狀態）。這可以降低電(dian)(dian)(dian)磁鐵(tie)的工作(zuo)時間，減少了能源浪費(fei)和(he)電(dian)(dian)(dian)磁鐵(tie)故障的發生率。

　　至(zhi)于說(shuo)電(dian)(dian)(dian)磁(ci)閥長時間通電(dian)(dian)(dian)工作，電(dian)(dian)(dian)磁(ci)閥是(shi)否能承受的(de)(de)住呢？電(dian)(dian)(dian)磁(ci)閥一般不(bu)會燒(shao)壞(huai)線(xian)圈(quan)，現在電(dian)(dian)(dian)磁(ci)閥線(xian)圈(quan)基本都是(shi)ED，這里(li)的(de)(de) ED指的(de)(de)是(shi)通電(dian)(dian)(dian)率，電(dian)(dian)(dian)磁(ci)閥可以滿(man)足的(de)(de)長期使用。表(biao)示可以持續通電(dian)(dian)(dian)。但如果使用方(fang)法(fa)不(bu)符(fu)合(he)通電(dian)(dian)(dian)率(ED)，會造成(cheng)線(xian)圈(quan)溫(wen)度上升以至(zhi)超過絕緣種(zhong)類的(de)(de)限制(zhi)溫(wen)度，嚴重時仍然會導致線(xian)圈(quan)被(bei)燒(shao)毀。

　　ASCO電磁(ci)閥能否持續通電工作太久(jiu)？會(hui)有什(shen)么影響(xiang)？

　　也就是說如果(guo)通(tong)(tong)電(dian)(dian)(dian)(dian)時(shi)間太長(chang)，那(nei)就取決于現場的(de)(de)具體(ti)情(qing)況。雖(sui)然通(tong)(tong)電(dian)(dian)(dian)(dian)時(shi)間長(chang)，發熱(re)嚴重(zhong)(zhong)燙手，但(dan)一(yi)般不會(hui)影(ying)響其(qi)工作。而如果(guo)電(dian)(dian)(dian)(dian)磁閥線(xian)圈(quan)(quan)通(tong)(tong)電(dian)(dian)(dian)(dian)，在空載狀態下，長(chang)期(qi)(qi)通(tong)(tong)電(dian)(dian)(dian)(dian)線(xian)圈(quan)(quan)肯(ken)定(ding)會(hui)燒(shao)壞(huai)。電(dian)(dian)(dian)(dian)磁閥長(chang)期(qi)(qi)通(tong)(tong)電(dian)(dian)(dian)(dian)的(de)(de)影(ying)響，一(yi)般其(qi)發熱(re)嚴重(zhong)(zhong)，不要用手觸摸(mo)。如果(guo)電(dian)(dian)(dian)(dian)磁閥線(xian)圈(quan)(quan)燒(shao)壞(huai)，會(hui)導致(zhi)閥門或其(qi)它執行機構不能正常工作，嚴重(zhong)(zhong)影(ying)響車間的(de)(de)正常生產(chan)。

　　綜(zong)上(shang)所述，ASCO電(dian)磁閥(fa)在(zai)生(sheng)產過程中十分重要，正(zheng)確的(de)選(xuan)擇至關重要。下面給大家幾個(ge)選(xuan)型的(de)依據：

　　1.根據流體(ti)參數選擇ASCO電磁閥的材(cai)質(zhi)；

　　2.根據(ju)(ju)連續工作時間的長短選擇(ze)電磁(ci)閥(fa)的類型；3.根據(ju)(ju)執行機構或應用(yong)選擇(ze)電磁(ci)閥(fa)的類型；

　　4.根據閥門(men)的類(lei)型選(xuan)擇；

　　5.根據環境條件選擇；

　　6.根據危險區域劃(hua)分選擇；

　　7.根據電壓選擇。

　　舉幾個例子：

　　1。當ASCO電(dian)磁閥需要長時間開(kai)啟，且維護時間大于停機(ji)時間時，可(ke)選(xuan)擇常開(kai)電(dian)磁閥。

　　2。當(dang)ASCO電磁閥開啟時(shi)間(jian)短或關閉時(shi)間(jian)與開啟時(shi)間(jian)相近時(shi)，可采(cai)用常閉式電磁閥。

　　3。在某(mou)些工況下，考慮到安(an)全保護需要長期(qi)通電(dian)，如鍋爐爐膛火焰監(jian)測，則(ze)需要選(xuan)用長期(qi)通電(dian)電(dian)磁(ci)閥。
