gas content
解釋
含氣量-
In pumping fluid with gas, pressure boost can be improved by enhancing the pump rotation speed, thereby improving the performance of the pump to a certain degree ; when the gas content is constant, by increasing the inlet pressure, the pressure boost can be enhanced and the pump efficiency be improved remarkably ; when the gas content is rather high, there will be a problem of matching between the gas pressure and the fluid pressure ; the performance of the multiphase pump can also be improved by means of rational design of buffer vessel and homogenizer
試驗分析認為，氣液混輸工況下，提高泵轉速可以提高增壓，在一定程度上能改善多相泵的工作性能；含氣率一定時，增加進口壓力，可使多相泵增壓值增大，泵效明顯增加，最大含氣率點后移，但含氣率很高時，存在氣液壓力相匹配問題；改進緩沖罐和均化器的設計，有利於氣液互相夾帶，避免氣囊產生，可改善多相泵的輸送性能。 -

為探討加入的氣體對管道壓力的影響，本文基於分相流和均相流兩種模型分別推導了三相流管道的壓降公式，表明無論是分相流模型，還是均勻流模型，管道內流體總的壓降是由三項組成的，即摩擦項、加速項和重力項，並得出了加氣對管壓變化不大的結論，所以認為在水平管道中，要獲得有效的減阻，則要使摩擦阻力分量的減小效應大於漿體加氣的加速效應。 -
