測(ce)硫儀(yi)應該注意的幾點事(shi)項(xiang)

1、測(ce)硫儀電解池(chi)(chi)的日常(chang)清(qing)洗(xi)(xi)：關閉(bi)氣(qi)泵/攪拌開關，拔掉(diao)電解池(chi)(chi)上(shang)(shang)的抽(chou)氣(qi)管(guan)，將電解液放出，接好電解池(chi)(chi)上(shang)(shang)的抽(chou)氣(qi)管(guan)，并抽(chou)入蒸(zheng)餾水(shui)，打(da)開氣(qi)泵/攪拌開關清(qing)洗(xi)(xi)電解池(chi)(chi)后再將水(shui)放干凈。

2、測硫儀解(jie)(jie)(jie)池(chi)(chi)電(dian)(dian)(dian)(dian)極的清(qing)(qing)洗(xi)(xi)：一(yi)般要求每檢測200個(ge)樣品左右，應清(qing)(qing)洗(xi)(xi)電(dian)(dian)(dian)(dian)極片（如經(jing)常(chang)分析高硫煤(mei)，則此數量還應少一(yi)些）。方法如下(xia)：拔掉(diao)電(dian)(dian)(dian)(dian)解(jie)(jie)(jie)池(chi)(chi)上抽氣嘴及進氣嘴的硅膠管(guan)、拔掉(diao)電(dian)(dian)(dian)(dian)解(jie)(jie)(jie)池(chi)(chi)上的連線插(cha)頭，取下(xia)電(dian)(dian)(dian)(dian)解(jie)(jie)(jie)池(chi)(chi)。松開電(dian)(dian)(dian)(dian)解(jie)(jie)(jie)池(chi)(chi)蓋，拿出攪拌子(zi)。用一(yi)手握住電(dian)(dian)(dian)(dian)極桿另一(yi)手拿酒精棉擦洗(xi)(xi)四個(ge)電(dian)(dian)(dian)(dian)極片的兩面，然后(hou)(hou)用蒸餾(liu)水沖洗(xi)(xi)電(dian)(dian)(dian)(dian)極片、以及擦洗(xi)(xi)電(dian)(dian)(dian)(dian)解(jie)(jie)(jie)池(chi)(chi)的杯體和上蓋，清(qing)(qing)洗(xi)(xi)完后(hou)(hou)放入(ru)攪拌子(zi)，按拆卸步驟裝好電(dian)(dian)(dian)(dian)解(jie)(jie)(jie)池(chi)(chi)。

3、測(ce)硫儀(yi)電(dian)(dian)(dian)解(jie)池(chi)氣(qi)體(ti)過(guo)(guo)濾(lv)(lv)器(qi)(qi)(qi)的清(qing)(qing)洗：當發現電(dian)(dian)(dian)解(jie)池(chi)的氣(qi)體(ti)過(guo)(guo)濾(lv)(lv)器(qi)(qi)(qi)中有黑色沉(chen)積物(wu)或(huo)堵塞嚴重時，應(ying)該清(qing)(qing)洗氣(qi)體(ti)過(guo)(guo)濾(lv)(lv)器(qi)(qi)(qi)。取下(xia)電(dian)(dian)(dian)解(jie)池(chi)，可不打開上蓋，在電(dian)(dian)(dian)解(jie)池(chi)中先(xian)放一(yi)些(xie)水，以不漫到氣(qi)體(ti)過(guo)(guo)濾(lv)(lv)器(qi)(qi)(qi)為宜，用(yong)滴管往進氣(qi)嘴中注入(ru)清(qing)(qing)洗液(ye)，待(dai)洗液(ye)流凈(jing)后(hou)(hou)，再反復加入(ru)2～3次，直到無黑色沉(chen)淀物(wu)或(huo)暢通即(ji)可，然后(hou)(hou)用(yong)清(qing)(qing)水沖洗電(dian)(dian)(dian)解(jie)池(chi)，氣(qi)體(ti)過(guo)(guo)濾(lv)(lv)器(qi)(qi)(qi)應(ying)潔白如初。

4、測(ce)硫儀氣路的(de)維護：因為(wei)儀器氣路系統的(de)狀態直(zhi)接影響檢(jian)測(ce)結果的(de)準確性，因此須經常對其進行維護。應定(ding)期更換過濾開(kai)(kai)關內的(de)棉花，一(yi)般每檢(jian)測(ce)200個(ge)試樣應更換。同時(shi)(shi)需(xu)對硅(gui)膠管(guan)進行除灰(hui)操作，并檢(jian)查該硅(gui)膠管(guan)與高(gao)溫(wen)爐相(xiang)連的(de)一(yi)端是否有穿孔(kong)(kong)，因該端溫(wen)度(du)較高(gao)，時(shi)(shi)間(jian)長(chang)后(hou)，管(guan)壁(bi)會變薄，如有穿孔(kong)(kong)則需(xu)更換，否則可調頭繼續使(shi)用。應確保(bao) 過濾開(kai)(kai)關的(de)磨口密封良好，定(ding)期加(jia)涂凡士林，并檢(jian)查其氣密性。
