href="http://www.sdjnmxd.com/Products-27374917.html" target="_blank">大氣粉塵采樣器</a></strong>是采集大氣污染物或受污染空氣的儀器或裝置。其種類很多，按采集對象可分為氣體采樣器和顆粒物采樣器；按使用場所可分為環境采樣器、室內采樣器和污染源采樣器。此外，還有特殊用途的恒流大氣采樣器，如同時采集氣體和顆粒物質的采樣器。</div><div>　　大氣粉塵采樣器在采樣過程中，接上過濾器，一方面對空氣進行過濾，因大氣中的灰塵、氣溶膠、酸堿氣等雜物很容易隨氣流被抽吸到泵內，這些雜物附在網片上就會影響隔膜泵的流量、抽氣壓力和穩定性，最終使恒流大氣采樣器的技術性能下降。</div><div>　　另一方面，大氣粉塵采樣器在發生倒吸溶液時，溶液一旦流經過濾器的過濾纖維，過濾纖維馬上膨脹，堵塞進氣通道，溶液便不會進一步流入隔膜泵內，對泵起到很好的保護作用。若發生倒吸溶液時，只需清洗過濾器，重新換上過濾纖維和泡沫塑料塊可解決問題。</div><div>　　大氣粉塵采樣器在工作中的優勢：</div><div>　　1.它不僅限于場地空間，而且易于移動。輕巧，您可以由一個人獨立操作。您可以方便地在火車，汽車，煤炭山等樣品上進行采樣。</div><div>　　2.結構緊湊，采用不銹鋼材質，外形美觀。螺旋筒的底部被加強，螺旋背板合金材料被加強。它能夠切割大型材料并且耐用。</div><div>　　3.與大型采樣設備（如汽車和火車）相比，性價比非常高。易于維護，打開螺旋桶和去除異物很容易。</div>
