電磁閥(fa)的選型(xing) 

一:適(shi)用(yong)(yong)性 管路中(zhong)的(de)(de)(de)流(liu)(liu)體(ti)必(bi)須和選(xuan)用(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥系列型號中(zhong)標定的(de)(de)(de)介質(zhi)*. 流(liu)(liu)體(ti)的(de)(de)(de)溫度(du)必(bi)須小(xiao)于(yu)(yu)(yu)選(xuan)用(yong)(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥的(de)(de)(de)標定溫度(du). 電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥允(yun)許液體(ti)粘(zhan)度(du)一般在 20CST 以下,大于(yu)(yu)(yu) 20CST 應注(zhu)明(ming). 工作壓(ya)差(cha),管路zui高(gao)壓(ya)差(cha)在小(xiao)于(yu)(yu)(yu) 0.04MPa 時(shi)應選(xuan)用(yong)(yong)如 ZS,2W,ZQDF,ZCM 系列等直動式和分步直動式; zui低工作壓(ya)差(cha)大于(yu)(yu)(yu) 0.04MPa 時(shi) 可選(xuan)用(yong)(yong)先導式（壓(ya)差(cha)式）電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥;zui高(gao)工作壓(ya)差(cha)應 小(xiao)于(yu)(yu)(yu)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥的(de)(de)(de)zui大標定壓(ya)力(li);一般電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥都是(shi)單向工作,因此要注(zhu) 意(yi)是(shi)否(fou)有(you)反(fan)壓(ya)差(cha),如有(you)安(an)裝止回閥. 流(liu)(liu)體(ti)清(qing)潔度(du)不(bu)高(gao)時(shi)應在電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥前(qian)安(an)裝過濾器,一般電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci) 閥對介質(zhi)要求清(qing)潔度(du)要好. 注(zhu)意(yi)流(liu)(liu)量(liang)孔徑和接管口徑;電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥一般只有(you)開關兩位控制;條件允(yun) 許請安(an)裝旁路管,便于(yu)(yu)(yu)維修;有(you)水錘現象時(shi)要定制電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥的(de)(de)(de)開閉時(shi) 間調節. 注(zhu)意(yi)環境溫度(du)對電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥的(de)(de)(de)影響 電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)流(liu)(liu)和消(xiao)耗功率應根(gen)據輸出容量(liang)選(xuan)取(qu),電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)壓(ya)一般允(yun)許 ±10%左右,必(bi)須注(zhu)意(yi)交流(liu)(liu)起動時(shi) VA 值較(jiao)高(gao). 

二,可(ke)靠(kao)性(xing) 電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)分為常(chang)(chang)閉(bi)和常(chang)(chang)開(kai)二種;一般(ban)選用(yong)(yong)常(chang)(chang)閉(bi)型(xing)(xing)(xing),通電(dian)(dian)打開(kai),斷電(dian)(dian)關 閉(bi);但在開(kai)啟時(shi)(shi)(shi)間(jian)很長(chang)關閉(bi)時(shi)(shi)(shi)很短時(shi)(shi)(shi)要選用(yong)(yong)常(chang)(chang)開(kai)型(xing)(xing)(xing)了(le). 壽(shou)命試(shi)驗,工廠(chang)一般(ban)屬于型(xing)(xing)(xing)式試(shi)驗項目(mu),確切地說我國還沒有(you)電(dian)(dian)磁(ci)(ci)(ci) 閥(fa)(fa)的(de)專業(ye)標(biao)準,因此選用(yong)(yong)電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)廠(chang)家時(shi)(shi)(shi)慎重. 動(dong)作(zuo)時(shi)(shi)(shi)間(jian)很短頻率較(jiao)高(gao)時(shi)(shi)(shi)一般(ban)選取直動(dong)式,大(da)口徑選用(yong)(yong)快速系列. 三(san),安全性(xing) 一般(ban)電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)不(bu)防水(shui), 在條件不(bu)允許(xu)時(shi)(shi)(shi)請(qing)選用(yong)(yong)防水(shui)型(xing)(xing)(xing), 工廠(chang)可(ke)以(yi)定做. 電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)的(de)zui高(gao)標(biao)定公稱壓(ya)力一定要超過管(guan)路內的(de)zui高(gao)壓(ya)力,否(fou)則使 用(yong)(yong)壽(shou)命會縮短或產生(sheng)其它意(yi)外情(qing)況. 有(you)腐(fu)蝕(shi)性(xing)液體的(de)應(ying)選用(yong)(yong)全不(bu)銹鋼型(xing)(xing)(xing),強腐(fu)蝕(shi)性(xing)流體宜選用(yong)(yong)塑料王 （SLF）電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa). 爆炸(zha)性(xing)環(huan)境必須(xu)選用(yong)(yong)相應(ying)的(de)防爆產品. 四(si),經(jing)濟(ji)性(xing) 有(you)很多電(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)可(ke)以(yi)通用(yong)(yong),但在能滿足以(yi)上三(san)點的(de)基(ji)礎上應(ying)選用(yong)(yong)zui經(jing) 濟(ji)的(de)產品。
