一般情況下，生產(chǎn)廠商會標(biāo)明1次標(biāo)定的有效使用時間為1年或2年，到期需重新標(biāo)定。其它注意事項濕度傳感器是非密封性的，為保護測量的準(zhǔn)確度和穩(wěn)定性，應(yīng)盡量避免在酸性、堿性及含有機溶劑的氣氛中使用。也避免在粉塵較大的環(huán)境中使用。為正確反映欲測空間的濕度，還應(yīng)避免將傳感器安放在離墻壁太近或空氣不流通的死角處。如果被測的房間太大，就應(yīng)放置多個傳感器。有的濕度傳感器對供電電源要求比較高，否則將影響測量精度。或者傳感器之間相互干擾，甚至無法工作。

一般較適宜的著火點離噴口.3～.5m之間。焰中心的調(diào)整在不一樣負(fù)荷下經(jīng)過改動輔佐風(fēng)巨細(xì)來改動風(fēng)箱與爐膛的壓差，調(diào)整火焰的剛性，經(jīng)過檢測爐膛溫度及調(diào)查水冷壁結(jié)焦情況來判別爐內(nèi)的火焰中心方位，使?fàn)t內(nèi)火焰不沖刷水冷壁，火焰中心堅持在爐膛中心。然后斷定輔佐風(fēng)擋板開度及風(fēng)箱與爐膛差壓。膛配件出口兩邊煙氣(汽溫)誤差的調(diào)整爐膛出口兩邊煙溫(或汽溫)的誤差，可經(jīng)過改動BC層和消旋風(fēng)的擋板開度來調(diào)理。
當(dāng)下把振打敘述描述一下，自動時含塵氣流從箱體下頭進入反吹式布袋除塵器容器后，容器中的大顆粒塵埃，由于空氣流假設(shè)擴大，流速降低，很明顯可能會沿筒壁下落；粒度細(xì)、密度小的微小塵粒懸浮于流體中通過空氣流分布裝置，均勻進入過濾室中彌散于除塵器濾袋間隙，通過除塵器濾袋的地方的慣性碰撞、篩濾等功效而沉積在除塵器濾袋的地方，凈化流體由主風(fēng)機排出。在說一下反吹式布袋除塵器的另一個常識如下，反吹式布袋除塵器阻力值的增大是于塵埃層不斷的增厚，而且塵埃不斷附著于除塵器濾袋表面的原因；當(dāng)阻力值到達一定值時，這時操作這一部分的零件，歐特爾脈沖閥就會發(fā)信號，把持歐特爾脈沖閥開啟，高壓氣包內(nèi)的壓縮空氣通；當(dāng)然了，如果沒有灰塵了或是小到一定的程序了，掃灰工作會停止工作的。
