【摘要】：通過系列試驗觀察了虹吸管道安裝高度為4 m及6 m時坡比及不同水頭差下中行管路傾斜布置的虹吸管內(nèi)的水氣兩相流動穩(wěn)定虹吸時間的長短。通過試驗研究發(fā)現(xiàn),虹吸時間與水頭差、安裝高度及坡比均有關(guān)。虹吸時間隨水頭差及安裝高度的增大而增大;在正、逆坡管路中,隨著坡比的增大,管內(nèi)偽空化現(xiàn)象逐漸減弱,穩(wěn)定虹吸時間逐漸增大;坡比不變時,正坡管路虹吸時間均大于逆坡管路,各種工況下平坡管路的虹吸時間最短。
[Abstract]:The length of stable siphon time of two-phase flow in siphon pipe with slope ratio of 4 m and 6 m and siphon pipe inclined arrangement with different head difference is observed by series of tests. It is found that siphon time is related to water head difference, installation height and slope ratio. The siphon time increases with the increase of water head difference and installation height, and the pseudo-cavitation phenomenon weakens gradually and the stable siphon time increases with the increase of slope ratio. When the slope ratio is constant, the siphon time of the straight slope pipe is longer than that of the inverse slope pipe, and the siphon time of the flat slope pipe is the shortest under various working conditions.
