阿斯卡防爆電磁閥優(yōu)點(diǎn):
1、防爆電磁閥工作壽命長(zhǎng)。
2、防爆電磁閥工作制式:分長(zhǎng)期工作制,反復(fù)短時(shí)工作制和短時(shí)工作制三種。防爆電磁閥均為長(zhǎng)期工作制,即線圈允許長(zhǎng)期通電工作。對(duì)于長(zhǎng)時(shí)間閥門開(kāi)通只有短時(shí)關(guān)閉的情況,則宜選用常開(kāi)電磁閥。用在短時(shí)工作制而批量又很大時(shí),可作特殊訂貨以降低功耗。
3、防爆電磁閥工作頻率:動(dòng)作頻率要求高時(shí),結(jié)構(gòu)應(yīng)優(yōu)選直動(dòng)式電磁閥,電源聽(tīng)優(yōu)選交流NFG551B418MO,52100002,EF8210G089,NFB307B35F,8344G072 SCE210C093,833-354011006,EF8342G003PMS, E290A133,54190017,VCEFG551A301, E290A125,SCB344A370,PSF8262G2PSF8262C2,HT8321G1,NF8551B317MO,NFHTB327A002,

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