【摘要】 为提高射流泵的传能传质效率,在相同的液体射流泵试验装置上,采用脉冲射流和恒定射流对液体射流泵的压力变化特性进行了试验研究。结果表明,脉冲与恒定液体射流泵内压力沿程变化规律基本相同,而在面积比相同、流量比近似相同的条件下,液体射流泵的脉冲射流压力特性优于恒定射流压力特性,为深入研究脉冲液体射流泵的基本性能提供了参考依据。更多还原

【Abstract】 In order to increase efficiency of jet flow pump for mass and energy transfer,pressure variation characteristics of the liquid jet flow pump are experimented with the pulse jet and the steady jet in the same liquid jet flow pump experimental apparatus.The results show that the pressure variations of pulse jet flow pump have the same law with steady jet flow pump,and the pressure characteristics of the pulse liquid jet flow pump is better than that of the steady liquid jet flow pump under the same area ratio and flow ratio,which provides reliable basis for studying fundamental performance of pulse liquid jet flow pump.更多还原
