一般情況下，生產廠商會標明1次標定的有效使用時間為1年或2年，到期需重新標定。其它注意事項濕度傳感器是非密封性的，為保護測量的準確度和穩(wěn)定性，應盡量避免在酸性、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�；蛘邆鞲衅髦g相互干擾，甚至無法工作。
HR-15A洛氏硬度計試驗前的準備工作一使用范圍試驗時立按下表選用壓頭和總試驗力:刻度符號壓頭總試驗力N（kg標注硬度符號允許測量范圍B∮1.588/mm鋼球98.7HRB2-1C12金剛石1471（15）HRC2-7A12金剛石588.4HRA2-88A標尺:用于測定硬度超過7HRC的金屬（如碳化鎢,硬質合金等）,也可測定硬的薄板材料以及表面淬硬的材料.C標尺:用于測定経過熱處理的鋼制品硬度.B標尺:用于測定較軟的或中等硬度的金屬以及未經淬硬的鋼制品.調整主試驗力的加荷速度;試驗力的選擇（15KG:1471N1KG/98.7N6KG/588N））;小心安裝硬度計壓頭.2.試驗程序將絲杠頂面及工作臺上下端面擦凈,將工作臺置于絲杠臺上;將試件支撐面擦凈置于工作臺上,旋轉手輪使工作臺緩慢上升并頂起壓頭,至小指針指向紅點,大指針旋轉3圈垂直向上為止;旋轉指示器外殼,使C,B之間長刻線與大指針對正;拉動加荷手柄,施加主試驗力,指示器的大指針按逆時針方向轉動;當指示針轉動停止下來后,即可將卸荷手柄推回,卸除主試驗力;從指示器上相應的標尺讀數(shù);轉動手輪使試件下降,再移動試件.按以上-步驟進行新的試驗;試驗結束后用防塵罩將機器蓋好.3.注意事項:定期在絲杠與手輪的接觸面注入少量機油;硬度計使用前,應將絲杠頂面和工作臺上端面擦凈;定期用標準硬度塊檢查硬度計精度,決不允許在支撐面試驗;當標準硬塊支承面有毛刺時應用油石打光,在其不同位置試驗時,硬塊應在工作臺上拖動,不應拿離工作臺.洛氏硬度計主要技術參數(shù)洛氏標尺:HRA,HRB,HRC,HRD,HRE,HRF,HRG,HRH,HRK初試驗力（N）:98.7（1kg）總試驗力（N）:588（6kg）,98（1kg）,1471（15kg）硬度值讀數(shù)方式:表盤試件允許大高度:17mm壓頭中心到機身距離:165mm洛氏硬度計外形尺寸（mm）:52247洛氏硬度計重量（kg）:8執(zhí)行標準:GB/T23.2標準、JJG112檢定規(guī)程硬度值范圍HRA:2～88HRB:2～1HRC:2～7標準配件（附件）:金剛石洛氏壓頭、直徑1.5875mm硬質合金球壓頭大平試臺、中平試臺、V型試臺、HRHRB硬度塊。2閥芯、閥桿、導向套閥芯是調節(jié)流量的關鍵件，也是沖蝕嚴重的零件之一，對閥芯結構及材料的選擇決定了閥門的性能。而導向套的設計，對閥芯穩(wěn)定性、調節(jié)性及運動性都起決定作用。導向套安裝在上下腔隔離面上，使導向面下移穩(wěn)定閥芯，克服了傳統(tǒng)文丘里角閥高進低出時的高頻振動、噪聲及調節(jié)性能不好問題。在導向套內孔設有凹槽，與隔離面上的孔形成壓力平衡效果。導向套的內孔及暴露在流道區(qū)的外圓都經過表面硬化處理，保證內孔的耐磨性能、外圓的抗沖蝕性能。
一般較適宜的著火點離噴口.3～.5m之間。焰中心的調整在不一樣負荷下經過改動輔佐風巨細來改動風箱與爐膛的壓差，調整火焰的剛性，經過檢測爐膛溫度及調查水冷壁結焦情況來判別爐內的火焰中心方位，使爐內火焰不沖刷水冷壁，火焰中心堅持在爐膛中心。然后斷定輔佐風擋板開度及風箱與爐膛差壓。膛配件出口兩邊煙氣(汽溫)誤差的調整爐膛出口兩邊煙溫(或汽溫)的誤差，可經過改動BC層和消旋風的擋板開度來調理。
當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，由于空氣流假設擴大，流速降低，很明顯可能會沿筒壁下落；粒度細、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，高壓氣包內的壓縮空氣通；當然了，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。
