摘　　要：在相同的液-气射流泵实验装置上,采用脉冲和恒定工作液体射流,对液气射流泵的基本性能进行了试验研究。结果表明,对于恒定液-气射流泵存在一种最优工作压力,而脉冲液-气射流泵在同一脉冲频率、不同工作压力下的性能曲线基本重合;采用脉冲工作射流可以产生水锤效应,正是这种水锤效应,使得脉冲液-气射流泵在低于试验系统提供的极限压力0.1～0.15 MPa的工作压力范围内,液-气射流泵的工作效率可以提高4%～15%。The fundamental performances of liquid gas jet pump have been investigated using the steady and pulsed liquid jet in the same liquid gas jet pump experimental apparatus. The results show that there is a optimal working pressure for steady liquid gas jet pump, and the performance curves of pulsed liquid gas jet pump are very similar in a certain pulsed frequency and different working pressure; the pulsed jet can produce water hammer effect, which could increase the liquid gas jet pump efficiency 4%-15% under limit working pressure 0.1Mpa-0. 15Mpa of experimental apparatus.
