根据脉冲液体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,研究了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,证明了脉冲频率、脉冲装置对脉冲液体射流泵的主要流动部件的能量损失压力比有一定的影响;且脉冲射流是提高射流泵传能及传质效率的有效途径。

By Applying the theorem of energy equilibrium analysis, the energy conversion and the waste of flow unit are analyzed systematically. Based on the energy loss pressure ratio formula of the main flow unit of pulsed liquid jet pump, the experimental study is carried out to investigate the pulsed liquid jet pump’s energy equilibrium, and the relation between energy transition and pulsed frequency in the main flow parts of pulsed liquid jet pump; then the results of the experimental data are compared with the theoretical data, it shows that the two agree well, the pulsed frequency and the pulsed device affect in the energy loss pressure ratio of the main flow unit of pulsed jet pump, and the pulsed jet is an effective way to enhance energy and quality transmission efficiency of the jet pump.
