摘　　要：根据脉冲液-气射流泵主要流动部件的能量损失压力比,对其能量平衡进行试验,研究主要过流部件的能量转化与脉冲频率之间的关系;与恒定液体射流泵试验数据进行对比,证明脉冲频率、脉冲装置对脉冲液-气射流泵的主要流动部件的能量损失压力比有一定的影响,脉冲射流是提高射流泵传能及传质效率的有效途径。By using the theorem of energy equilibrium analysis,energy conversion and waste of flowing unit are analyzed systematically.Based on the energy loss pressure ratio expression formula of the main flowing unit of pulsed liquid gas jet pumps,an experimental study is carried out to study pulsed liquid gas jet pump’s energy equilibrium,and this paper studies the relation between energy transition and pulsed frequency in the main flowing parts of pulsed liquid gas jet pumps,then compares the results of the experimental data with the theory data.Results show that the two tallies and pulsed frequency and pulsed device are exerting a great effect on the energy loss pressure ratio of the main flowing unit of pulsed jet pumps,and the pulsed jet is an effective way to enhance energy and quality transmission efficiency of the jet pump.
