id="pjhforxw" class="news_detail"> <h1>煙塵采樣器的使用方法和注意事項說明</h1> <div id="pjhforxw" class="nwdtl_tip"><span>更新時間：2021-10-09</span><span>瀏覽：3606次</span></div> <div id="pjhforxw" class="nwdtl_con"> <div><strong>煙塵采樣器</strong>是一種常見的環(huán)境監(jiān)測儀器，廣泛應(yīng)用于學校、醫(yī)院、工廠等一些戶外或者比較惡劣的環(huán)境，高空作業(yè)居多，因此一定要注意操作人員的人身安全。</div><div> </div><div><strong>煙塵采樣器</strong>使用方法如下：</div><div> </div><div>1、使用前準備：</div><div> </div><div>按下儀器背后的直流開關(guān)，查看電壓指示條形碼，(條形碼為五格)如果只剩最后一格微亮，則蓄電池需充電。</div><div> </div><div>2、充電：</div><div> </div><div>該儀器設(shè)定充電時間為7小時，插上電源插頭，按下背板直流開關(guān)，面板電壓指標條形碼亮，然后再按下面板充電按鈕，充電指示燈亮充電開始，同時數(shù)碼管面板顯示充電時間420分鐘，充電時間設(shè)置為倒計時。數(shù)碼管顯示全部為零，充電指示燈熄，充電完畢。充電期間中途停電，不論時間長短，來電后會繼續(xù)充電。充電期間如需儀器工作，則按復(fù)位鍵即可。充電過程中，條形碼應(yīng)全亮，若不亮則充電失靈，須排除故障后再充。</div><div> </div><div>3、采樣：</div><div> </div><div>(1)采樣時，展開“三腳架”將儀器主機置于其上面，旋緊“三角架”上固定螺釘。其高度在0.7~1.7m之內(nèi)可根據(jù)需要進行調(diào)節(jié)，以操作者平視“轉(zhuǎn)子流量計”刻度為最宜。</div><div>(2)將2個“采樣頭”裝好采樣濾膜，安裝在背板兩個“采樣頭座”上，旋緊即可。</div><div>(3)流量調(diào)節(jié)，首先要設(shè)置流量調(diào)節(jié)，時間1分鐘。打開背板直流開關(guān)，電機瞬時啟動，待“數(shù)碼管”全部為零停止時，按“加”鍵，使“數(shù)碼管”為1，然后按“采樣”鍵，泵開始工作，旋開“流量調(diào)節(jié)閥”，將流量調(diào)到所需流量，亦可用流量調(diào)節(jié)閥進行微調(diào)，調(diào)節(jié)儀器側(cè)面流量調(diào)節(jié)旋鈕，到1分鐘后，會自動停機。</div><div>(4)設(shè)置，按下“加”鍵不松開，直到調(diào)到所需時間為止，松開即停。</div><div>(5)按下“采樣”鍵，采樣開始，直到設(shè)置采樣時間下降為零時，采樣自動停止。中途如需停止采樣，再次將“采樣”鍵按下即可停止。</div><div> </div><div>使用注意事項：</div><div> </div><div>1、儀器在使用期間，每次采樣結(jié)束后，必須用干凈的空氣對儀器的傳感器、泵、煙塵取樣管、氣路連接橡膠管進行清洗。清洗的方法如下：測完煙氣后，根據(jù)儀器提示進行清洗。</div><div> </div><div>2、測完煙塵后，將含塵濾筒取出，保持整機連接狀態(tài)，將采樣嘴置于純凈空氣中，進入“工況測量->含濕量測量”界面，煙塵泵將以20L/min的流量吸入純凈空氣對采樣系統(tǒng)進行清洗。清洗可在幾分鐘完成。</div><div> </div><div>3、儀器長時間閑置不用時，應(yīng)每個月通電一次，時間不小于4小時。</div> </div> </div>
