擴散型過濾器的工作原理是什么?

  擴散型過濾器(也被稱為擴散過濾器、導(dǎo)流過濾器、吸入口過濾器等),是一種安裝于水泵入口的新型工業(yè)過濾設(shè)備,屬于工業(yè)管道系統(tǒng)中的前置過濾裝置。其工作原理主要涉及到介質(zhì)的過濾與流向的調(diào)整,具體來說:
  一、介質(zhì)過濾
  過濾過程:介質(zhì)從進口端進入濾筒外部,通過具有大面積開口的過濾網(wǎng)進行過濾,雜質(zhì)被截留在網(wǎng)筒外部,而潔凈的介質(zhì)則通過網(wǎng)筒內(nèi)部繼續(xù)流動。
  濾網(wǎng)結(jié)構(gòu):擴散型過濾器通常采用雙層大開口過濾網(wǎng)結(jié)構(gòu),這種設(shè)計能夠減小壓力損失,提高泵的效率。同時,濾網(wǎng)支持不同精度的定制,以滿足不同應(yīng)用場景的需求。
  二、流向調(diào)整與平衡
  擴散流向:過濾器能夠自身擴散流向,并在流動過程中降低管道內(nèi)的流速。通過內(nèi)部導(dǎo)向板(或稱為流體平衡葉片)使流體分散并均勻分布流速,從而保障了泵的長期穩(wěn)定運行。
  導(dǎo)流作用:當(dāng)過濾器直接安裝在泵的入口處時,它能夠起到導(dǎo)流作用,為泵提供平衡的水流。這有助于保護泵的葉片,避免由于流速不均或流速過快導(dǎo)致的損傷。
 

 

  三、排污與清洗
  排污口設(shè)計:過濾器筒體上通常設(shè)有排污口,方便用戶定期進行排污操作,以去除截留在濾筒外部的雜質(zhì)。
  清洗便利性:為了方便清洗過濾網(wǎng),擴散型過濾器通常采用易于拆卸的濾網(wǎng)結(jié)構(gòu)。例如,通過鉸鏈式設(shè)計或后端蓋可打開的方式,用戶可以方便地取出過濾網(wǎng)筒進行清洗。
  四、應(yīng)用與優(yōu)勢
  應(yīng)用領(lǐng)域:過濾器廣泛應(yīng)用于化工、電力、石油等領(lǐng)域的流體輸送系統(tǒng),以及水、油、氣體、蒸汽等多種介質(zhì)的過濾。
  主要優(yōu)勢:通過雜質(zhì)過濾、水流穩(wěn)定及氣穴預(yù)防等功能,過濾器能夠提升水泵效率并延長設(shè)備使用壽命。此外,它還具有節(jié)省安裝空間、減少管道耗材和人工成本等優(yōu)勢。
  擴散型過濾器通過特別的介質(zhì)過濾和流向調(diào)整機制,實現(xiàn)了對流體的高效過濾和平衡輸送。其結(jié)構(gòu)設(shè)計和功能特點使其在各種工業(yè)應(yīng)用場景中具有廣泛的應(yīng)用前景。
