style="text-indent:25px">透明件的安裝防爆燈具離不開透明件，而透明件又是外殼部件中強度較低的部件，因此透明件安裝是否可靠直接影響防爆燈具的安全性能。下面分析一下三種常用的透明件安裝方式： 1、直接密封在外殼內，與外殼形成一個整體。這種方法簡單實用、使用普遍。密封材料應選用耐溫、耐油的橡膠件，或使用環(huán)氧樹脂等膠粘劑將透明件密封在外殼內并壓緊。 2、用襯墊或不用襯墊，直接將透明件緊固在外殼內。不用襯墊時透明件接合面的平整度要求很高，一般適合小型平板玻璃且將玻璃結合部位同時磨平，不然玻璃受力不均，容易碎裂。 3、密封或膠粘在一個框架上，框架緊固在外殼內，這樣可以將透明件作為整體更換。這種結構在燈具中使用很少，在一些須要經常更換透明件的大型設備上，將透明件和框架作為一個整體部件更換。透明件與框架的密封可以參考a的型式。在結構上，應盡量使透明件受到的(內部產生的)力直接傳遞到金屬外殼上，通過透明件的壓板和或螺釘再傳遞到金屬外殼上是不合適的，同時，透明件安裝后不能受到應力，這樣才能保證透明件與外殼結合可靠。</p><p style="text-indent:25px">透明件的安裝，防爆燈具離不開透明件，而透明件又是外殼部件中強度較低的部件，因此透明件安裝是否可靠直接影響防爆燈具的安全性能。下面分析一下三種常用的透明件安裝方式： 1、直接密封在外殼內，與外殼形成一個整體。這種方法簡單實用、使用普遍。密封材料應選用耐溫、耐油的橡膠件，或使用環(huán)氧樹脂等膠粘劑將透明件密封在外殼內并壓緊。 2、用襯墊或不用襯墊，直接將透明件緊固在外殼內。不用襯墊時透明件接合面的平整度要求很高，一般適合小型平板玻璃且將玻璃結合部位同時磨平，不然玻璃受力不均，容易碎裂。 3、密封或膠粘在一個框架上，框架緊固在外殼內，這樣可以將透明件作為整體更換。這種結構在燈具中使用很少，在一些須要經常更換透明件的大型設備上，將透明件和框架作為一個整體部件更換。透明件與框架的密封可以參考a)的型式。在結構上，應盡量使透明件受到的(內部產生的)力直接傳遞到金屬外殼上，通過透明件的壓板和或螺釘再傳遞到金屬外殼上是不合適的，同時，透明件安裝后不能受到應力，這樣才能保證透明件與外殼結合可靠?？紤]環(huán)境條件合理選擇具有各種功能的防爆燈具。</p><div

1、燈珠：國產1W燈珠有賣2毛錢的，為什么兩毛錢就敢賣？燈珠里面的金線用銅線代替，其他的原材料用劣質材料替代，這是消費者沒法察覺到的，而且標稱1W，但用設備檢測可能只有0.5W ，而消費者一般是不會去測試的。 2、外殼用些邊角鋁或者是塑膠，成本在1塊到3塊錢。 3、驅動電源現(xiàn)在市場上劣質的驅動有賣到1塊多的，甚至還有更低的，做防爆燈具的廠家倒閉的不知有多少，而那些為了謀利不負責任做劣質驅動的商家，卻不知賺了多少錢。隔爆型的防爆燈具，可適用電源不超過 l000V 的有白熾燈。節(jié)能防爆燈具報價</p><p

style="text-indent:25px">用螺栓緊固的的隔爆外殼有二種型式：平面和止口。對于平面結構，螺栓不僅起緊固作業(yè)，還要保證平面間隙。對于止口結構，當隔爆面只考慮圓筒部分時，螺栓只起緊固作用；當隔爆面需要考慮圓筒加平面時，螺栓不僅起緊固作業(yè)，同時起保證平面部分間隙作用。當在外殼上直接攻螺紋時必須注意：緊固件螺孔盡量不要穿過隔爆外殼，穿過外殼時螺孔底部應留有3mm以上的余量；在使用鋁合金等輕合金材料作隔爆外殼時，由于鋁合金強度較低，因此，經常打開(如更換光源需要打開)的隔爆外殼上使用螺釘緊固時，不應在鋁合金外殼上直接攻螺紋，應通過預埋防松的內外螺紋鋼套，來增加螺孔強度，并防止因螺紋爛牙而失效；不需要用戶在更換光源中或維修時打開，且出廠時已經安裝好的螺栓，可以在外殼上直接攻緊固螺孔，但是不能使用細牙螺紋，盡量使用粗牙螺紋，且有足夠的嚙合扣數(shù)來滿足緊固要求。總之，在設計外殼緊固件時，應首先分清其在隔爆外殼中的作用，是只起緊固作用，還是既起緊固同時還起保證平面間隙的作用，然后確定螺栓的較大軸向載荷選用合適的螺栓。節(jié)能防爆燈具報價</p><p
