移动式粉煤(mei)取样器(qi)概述
 

连云港灵动机电设备有限公司所生产制造的手动移动式粉煤取样器也可称为便携式煤(mei)粉取样(yang)器主要用于正压直吹式制粉系统-次风煤粉管上定期煤粉取样。

由于磨煤机碾磨件的磨损、煤种、块度的变化，煤粉细度将产生较大的变化，并直接影响锅炉燃烧的-率，因此定期对煤粉细度取样-测，当煤粉的细度超过设计值时，及时调整分离器折向门开度，或-换碾磨部件是十分-要的。
 

移动式粉煤(mei)取(qu)样(yang)器(qi)采用以(yi)压(ya)缩(suo)空(kong)气(qi)为动力-，用射气(qi)抽(chou)(chou)气(qi)器(qi)将(jiang)分离器(qi)内抽(chou)(chou)吸成负压(ya)原理(li)取(qu)样(yang)，同时还具(ju)有反吹扫功能(neng)，避(bi)-了(le)取(qu)样(yang)口堵塞(sai)问题的(de)出现，且(qie)易于取(qu)样(yang)。取(qu)样(yang)的(de)速度(du)(du)通过调整(zheng)压(ya)缩(suo)空(kong)气(qi)压(ya)力、流(liu)量而得到控制。一般压(ya)力控制在0.05-0.1Mpa,这样(yang)取(qu)样(yang)才会具(ju)有代(dai)表-，能(neng)够得到较遥(yao)遥(yao)的(de)煤(mei)粉细度(du)(du)值(zhi)。

移(yi)动(dong)式粉煤(mei)取样器(qi)在(zai)压(ya)(ya)缩(suo)空气(qi)阀后加装调压(ya)(ya)阀。因一般电厂提供的压(ya)(ya)缩(suo)空气(qi)的压(ya)(ya)力在(zai)4~6Kg左右(you)，单靠压(ya)(ya)缩(suo)空气(qi)阀来(lai)调节很难(nan)达到移(yi)动(dong)式粉煤(mei)取样器(qi)所需的工作压(ya)(ya)力，往往因压(ya)(ya)力过大而取样失真(zhen)，没有代表(biao)-。
