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。 -
Presents the steady - state programming with constant coolant average temperature and constant live steam pressure, an ideal programming for marine nuclear power plant ( npp ), under which, both the coolant average temperature and the live steam pressure of nuclear steam supply system ( nsss ) are constant when the steady state operating condition is varied, and points out that in comparison with the steadysate programming with constant coolant average temperature, the ideal programming can improve the overall operating performance of npp effectively, especially in low - load range, for instance, raise the heat efficiency of npp, decrease the operating noise of main coolant pump, and improve the conditions of design, operation and control of the secondary loop system
