style="text-indent:25px">電磁閥的電磁線圈流過電流就會(huì)發(fā)熱，溫度會(huì)逐漸升高。經(jīng)過一定時(shí)間后，發(fā)熱與散熱處于平衡，溫度便達(dá)到穩(wěn)定值。此溫度與環(huán)境溫度之差稱為溫升。---電磁閥線圈溫升屬于正常現(xiàn)象。電磁閥外部線圈高允許溫升由線圈的絕緣種類決定，電磁線圈的溫升值應(yīng)比高允許溫升低，電磁閥的環(huán)境溫度由線圈的絕緣種類的高允許溫度和電磁閥線圈的溫升值來決定，速牌通用電磁閥線圈使用B種絕緣，若環(huán)境溫度不高于60度，則電磁線圈溫升不超過70度。B級(jí)絕緣種類：高允許溫升為90度，高允許溫度為130度。杭州化工電磁閥生產(chǎn)廠家電磁閥不能使用粘性介質(zhì)，特定產(chǎn)品的粘度范圍相對(duì)狹窄。</p><div

style="text-indent:25px">電磁閥工作原理：電磁閥里有密閉的腔，在的不同位置開有通孔，每個(gè)孔都通向不同的油管，腔中間是閥，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊，通過控制閥體的移動(dòng)來檔住或漏出不同的排油的孔，而進(jìn)油孔是常開的，液壓油就會(huì)進(jìn)入不同的排油管，然后通過油的壓力來推動(dòng)油缸的活塞，活塞又帶動(dòng)活塞桿，活塞竿帶動(dòng)機(jī)械裝置動(dòng)。這樣通過控制電磁鐵的電流就控制了機(jī)械運(yùn)動(dòng)。分布直動(dòng)式電磁閥工作原理：它是一種直動(dòng)式和先導(dǎo)式相結(jié)合的原理。常閉式---當(dāng)入口與出口沒有壓差時(shí)，通電后電磁力直接打開先導(dǎo)孔連接主閥活塞依次向上提起，閥門打開；當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力先打開先導(dǎo)孔，主閥活塞上腔壓力下降，從而利用壓差和電磁力拉動(dòng)主活塞，閥口打開；斷電時(shí)，靠彈簧復(fù)位關(guān)閉先導(dǎo)孔，主活塞上腔增壓，推動(dòng)主活塞向下移動(dòng)，閥關(guān)閉。常開式與常閉式相反。</p><p style="text-indent:25px">電磁閥的選型要點(diǎn)：電磁閥選型應(yīng)先后遵照安全性，可靠性，適用范圍，合理性四項(xiàng)原則和六個(gè)層面的當(dāng)場(chǎng)工作狀況（管路主要參數(shù)、物質(zhì)主要參數(shù)、工作壓力主要參數(shù)、開關(guān)電源主要參數(shù)、姿勢(shì)方法、特別要求）。選型標(biāo)準(zhǔn)：安全性：即選型時(shí)要首先先充分考慮性命和資產(chǎn)安全，非常是易燃易爆物品場(chǎng)所。可靠性：姿勢(shì)不能的電磁閥可能危害系統(tǒng)軟件的其他元器件。適用范圍：選型一定要向**指導(dǎo)，例如買一只低溫閥用以蒸氣，相當(dāng)于費(fèi)品。合理性：就是指用以溫物質(zhì)則無須選高溫的，由于高溫的成本增加。電磁閥對(duì)介質(zhì)的清潔度有很高的要求，并且不能使用含有顆粒的介質(zhì)。</p><div
