1.探針式取樣器:這種取樣器是直接裝在汽包的飽和蒸汽引出管中。探針式取樣器能取得有樣例性的樣品，因為飽和蒸汽剛從汽包內(nèi)引出,它攜帶的水分分布得比較均勻，為了位置正確及防震動,應配定位支架，安裝時取樣器與管壁應削成30°的角。 </p> <p> 2.**式取樣器:本體是不銹鋼管,并焊有不銹鋼制的**, **式取樣器一般用在飽和蒸汽流速超過破膜速度5-6倍的管道中。 </p> <p> 3.縫隙式取樣器:是在不銹鋼管上開孔并另焊平行鋼板制成。這種取樣器一般用在有蒸汽雜質(zhì)怕堵的管道中。 </p> <p> 4.帶混合器型取樣器:這種取樣器由漸縮管、混合室、單**取樣管及漸擴管組成。該取樣器一般用在蒸汽流速未超過破膜速度的5-6倍的管道中，即可取得有樣例性的樣品。使用密閉采樣器采樣杜絕了采樣人員吸入樣品中揮發(fā)性物質(zhì)的可能，減少了職業(yè)病，保護了采樣人員的生命安全。連云港隱蔽式煤粉取樣器廠家</p><p style="text-indent:25px">該裝置具有手動及電動兩種操作方式，手動操作，外部備有手柄，取樣時只要操作人員搖動手柄即可取樣。連云港鍋爐給水取樣冷凝器廠家</p><p style="text-indent:25px">間接冷卻式汽水取樣冷卻裝置的應用：小型火力發(fā)電廠經(jīng)常采用一種簡易的汽水取樣冷卻裝置,直接用循環(huán)水或工業(yè)水作為冷卻介質(zhì),用作鍋爐爐水,過熱蒸汽和飽和蒸汽等取樣器的冷卻.往往由于循環(huán)水或工業(yè)水水質(zhì)較差,很容易導致取樣冷卻器冷卻管結垢,堵塞,嚴重影響使用壽命,從而也影響到水質(zhì)化驗結果,給鍋爐運行埋下安全事故隱患,為了解決這一問題,本文介紹一種間接冷卻式取樣冷卻裝置,從而保證了取樣冷卻裝置內(nèi)部冷卻管可以**結垢,保證了它的可靠使用.連云港鍋爐給水取樣冷凝器廠家</p><p
