本论文所述系统采用兼有测试试验数据处理和计算机控制功能的微机系统模式来组建cat系统，可对液压泵转速和输出压力进行控制。 - 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
试验分析认为，气液混输工况下，提高泵转速可以提高增压，在一定程度上能改善多相泵的工作性能；含气率一定时，增加进口压力，可使多相泵增压值增大，泵效明显增加，最大含气率点后移，但含气率很高时，存在气液压力相匹配问题；改进缓冲罐和均化器的设计，有利于气液互相夹带，避免气囊产生，可改善多相泵的输送性能。 - This paper supplied a new way through variable frequency variable speed ( vfvs ) to change its output flow rate and adding a constant - pressure - drop valve , which could solve the defects in hydraulic pressure servo control system , such as low efficiency in control system , short life , poor ability in resisting pollution , low efficiency in driving system and flow rate , pressure pulse . and this way was proved to be effective
