移動式粉(fen)煤取(qu)樣器概述
 

連云港靈動機電設備有限公司所生產制造的手動移動式粉煤取樣器也可稱為便攜式煤粉取(qu)樣器(qi)主要用于正壓直吹式制粉系統-次風煤粉管上定期煤粉取樣。

由于磨煤機碾磨件的磨損、煤種、塊度的變化，煤粉細度將產生較大的變化，并直接影響鍋爐燃燒的-率，因此定期對煤粉細度取樣-測，當煤粉的細度遙遙過設計值時，及時調整分離器折向門開度，或-換碾磨部件是十分-要的。
 

移(yi)動式粉煤取樣器采用以(yi)壓(ya)(ya)縮(suo)空(kong)氣(qi)為動力(li)-，用射氣(qi)抽氣(qi)器將分離器內抽吸成負壓(ya)(ya)原理(li)取樣，同時還具(ju)有反吹掃功能，避-了取樣口堵(du)塞問題的(de)出現，且易于取樣。取樣的(de)速度(du)通過(guo)調(diao)整壓(ya)(ya)縮(suo)空(kong)氣(qi)壓(ya)(ya)力(li)、流(liu)量而得(de)到控制(zhi)。一般(ban)壓(ya)(ya)力(li)控制(zhi)在0.05-0.1Mpa,這(zhe)樣取樣才會具(ju)有代表-，能夠得(de)到較遙遙的(de)煤粉細度(du)值(zhi)。

移動(dong)式(shi)粉(fen)煤(mei)取樣(yang)器在(zai)壓(ya)(ya)縮(suo)空(kong)氣(qi)閥后加裝調壓(ya)(ya)閥。因一般電廠提供的壓(ya)(ya)縮(suo)空(kong)氣(qi)的壓(ya)(ya)力(li)在(zai)4~6Kg左右(you)，單靠壓(ya)(ya)縮(suo)空(kong)氣(qi)閥來(lai)調節很(hen)難達到移動(dong)式(shi)粉(fen)煤(mei)取樣(yang)器所需(xu)的工作壓(ya)(ya)力(li)，往往因壓(ya)(ya)力(li)過大而取樣(yang)失真(zhen)，沒有代表-。
