産品概況
WFB型立式無密封自控自吸泵主要由泵體、工作葉輪(主葉輪)、副葉輪、泵軸、電機支架、電控閥、停車止回閥等裝置組成(chéng)。工作原理爲氣液混合式,在泵運轉前,泵體内存在一定量的液體,泵啓動後(hòu),由于工作葉輪的旋轉作用。使進(jìn)液管内的空氣與泵體内的液體充分混合,并被(bèi)排到氣液分離室,氣液分離室内的空氣從上部逸出,液體從下部返回葉輪進(jìn)口,重新和進(jìn)液管的剩餘空氣混合,不斷循環,直到把進(jìn)液管内的空氣全部排盡,完成(chéng)自吸.
工作原理
工作原理:自吸泵的主要水力元件葉輪和泵殼與一般離心泵相似,泵腔内增加了儲液室和氣水分離室。WFB型無密封自吸泵,無密封應該爲副葉輪動力密封,又稱爲流體動力密封。它可以克服填料密封及機械密封的某些不足,可以确保無洩漏。
副葉輪動力密封原理
副葉輪在工作葉輪上部,運行時和工作葉輪一起(qǐ)旋轉,其作用是減低泵腔的壓力,達到平衡軸向(xiàng)力和防止液體進(jìn)入密封裝置。副葉輪其實是依靠壓力頂住工作葉輪出口處的高壓液體向(xiàng)外洩漏,停機時副葉輪不起(qǐ)作用,所以應配備停機密封,防止泵腔水外流。
注意要點
因WFB型立式自吸泵的泵腔内水力損失比一般離心泵要大,所以配用功率相對(duì)較大,WFB無密封自控自吸泵的電控閥作爲自吸泵的組成(chéng)部分之一裝在吸液口的進(jìn)氣管上,啓泵時電控閥密閉泵體吸液管上的進(jìn)氣口,使自吸泵泵腔内形成(chéng)真空,完成(chéng)自吸全過(guò)程。
停泵時電控閥開(kāi)啓,空氣從密閉口進(jìn)入水泵液管内迅速隔離吸液管内共流的介質,确保泵腔的介質不随吸液管腔内的介質回落到吸液池中,以達到消除虹吸的目的,确保自吸泵二次自吸時正常自吸及運行,自吸泵停機後(hòu)出口止回閥靠回水重力關閉,使泵腔内液體不會(huì)流出。
