阿斯卡防爆電磁閥優點:
1、防爆電磁閥工作壽命長。
2、防爆電磁閥工作制式:分長期工作制,反復短時工作制和短時工作制三種。防爆電磁閥均為長期工作制,即線圈允許長期通電工作。對于長時間閥門開通只有短時關閉的情況,則宜選用常開電磁閥。用在短時工作制而批量又很大時,可作特殊訂貨以降低功耗。
3、防爆電磁閥工作頻率:動作頻率要求高時,結構應優選直動式電磁閥,電源聽優選交流NFG551B418MO,52100002,EF8210G089,NFB307B35F,8344G072 SCE210C093,833-354011006,EF8342G003PMS, E290A133,54190017,VCEFG551A301, E290A125,SCB344A370,PSF8262G2PSF8262C2,HT8321G1,NF8551B317MO,NFHTB327A002,

阿斯卡電磁閥的zui高標定公稱壓力一定要超過管路內的zui高壓力,否則使用壽命會縮短或產生其它意外情況。有腐蝕性液體的應選用全不銹鋼型,強腐蝕性流體宜選用塑料王(ZCF)電磁閥。爆炸性環境必須選用相應的防爆產品。

ASCO電磁閥允許液體粘度一般在20CST以下,大于20CST應注明。工作壓差,管路zui高壓差在小于0.04MPA時應選用寧波艾爾派克公司如ZS,2W,ZQDF,ZCM系列等直動式和分步直動式;zui低工作壓差大于0.04MPA時可選用先導式(壓差式)電磁閥;zui高工作壓差應小于電磁閥的zui大標定壓力;一般電磁閥都是單向工作,因此要注意是否有反壓差,如有安裝止回閥。

ASCO防爆電磁閥是把設備可能點燃爆炸性氣體混合物的部件全部封閉在一個外殼內,其外殼能夠承受通過外殼任何接合面或結構間隙,滲透到外殼內部的可燃性混合物在內部爆炸而不損壞,并且不會引起外部由一種、多種氣體或蒸氣形成的爆炸性環境的點燃,把可能產生火花、電弧和危險溫度的零部件均放入隔爆外殼內,隔爆外殼使設備內部空間與周圍的環境隔開。隔爆外殼存在間隙,因電氣設備呼吸作用和氣體滲透作用,使內部可能存在爆炸性氣體混合物。
