適用范圍

PXK系列正壓型儀表/配電柜，適用于石油、化工、海上鉆井平臺、醫藥生物、輕紡、食品等爆炸性環境中，主要原理為：系用隔離介質是潔凈的空氣，通過各種保護裝置，使正壓腔內聞的保護氣體相對于外部危險環境大氣有一定的正壓，從而阻止易燃混合物進入正壓起動殼體

PXK Series positive pressure instruments/power distribution cabinet,suitable for the explosive environment such as petroleum and chemical industry,off-shore drilling platform,medical biology,light &textile industry and food-stuff etc.Main principle is:the isolating medium is the clean air,Various protection devices in the conbinet makes the protective gas inside the positive chamber to have definite positive pressure relative to the external hazardous ambient atmosphere,thus prevent the combustible mixtures from being entered into the starting casing which has the positive pressure

該產品具有自動延時換氣，欠壓自動補氣、報警、失壓自動斷電等功能
This product has such functions as auto matic time delayed purging,automatic air supplementing and slarming,when underp[ressure,and auto matic power disconnecting wher no air
