水泵開動前，先將泵和進(jìn)水管灌滿水，水泵運(yùn)轉(zhuǎn)后，在葉輪高速旋轉(zhuǎn)而產(chǎn)生的離心力的作用下，葉輪流道里的水被甩向四周，壓入蝸殼，葉輪入口形成真空，水池的水在外界大氣壓力下沿吸水管被吸入補(bǔ)充了這個空間。繼而吸入的水又被葉輪甩出經(jīng)蝸殼而進(jìn)入出水管。由此可見，若離心泵葉輪不斷旋轉(zhuǎn)，則可連續(xù)吸水、壓水，水便可源源不斷地從低處揚(yáng)到高處或遠(yuǎn)方。綜上所述，離心泵是由于在葉輪的高速旋轉(zhuǎn)所產(chǎn)生的離心力的作用下，將水提相高處的，故稱離心泵。水沿離心泵的流經(jīng)方向是沿葉輪的軸向吸入，垂直于軸向流出，即進(jìn)出水流方向互成90°。由于離心泵靠葉輪進(jìn)口形成真空吸水，因此在起動前必須相泵內(nèi)和吸水管內(nèi)灌注引水，或用真空泵抽氣，以排出空氣形成真空...更多詳情》。烏魯木齊螺旋管廠博州聚氨酯保溫管批發(fā)
