產(chǎn)品概況
WFB型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。工作原理為氣液混合式,在泵運轉(zhuǎn)前,泵體內(nèi)存在一定量的液體,泵啟動后,由于工作葉輪的旋轉(zhuǎn)作用。使進液管內(nèi)的空氣與泵體內(nèi)的液體充分混合,并被排到氣液分離室,氣液分離室內(nèi)的空氣從上部逸出,液體從下部返回葉輪進口,重新和進液管的剩余空氣混合,不斷循環(huán),直到把進液管內(nèi)的空氣全部排盡,完成自吸.
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,泵腔內(nèi)增加了儲液室和氣水分離室。WFB型無密封自吸泵,無密封應該為副葉輪動力密封,又稱為流體動力密封。它可以克服填料密封及機械密封的某些不足,可以確保無泄漏。
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旋轉(zhuǎn),其作用是減低泵腔的壓力,達到平衡軸向力和防止液體進入密封裝置。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外泄漏,停機時副葉輪不起作用,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內(nèi)水力損失比一般離心泵要大,所以配用功率相對較大,WFB無密封自控自吸泵的電控閥作為自吸泵的組成部分之一裝在吸液口的進氣管上,啟泵時電控閥密閉泵體吸液管上的進氣口,使自吸泵泵腔內(nèi)形成真空,完成自吸全過程。
停泵時電控閥開啟,空氣從密閉口進入水泵液管內(nèi)迅速隔離吸液管內(nèi)共流的介質(zhì),確保泵腔的介質(zhì)不隨吸液管腔內(nèi)的介質(zhì)回落到吸液池中,以達到消除虹吸的目的,確保自吸泵二次自吸時正常自吸及運行,自吸泵停機后出口止回閥靠回水重力關(guān)閉,使泵腔內(nèi)液體不會流出。
