摘　　要：水射流中掺入适量空气可以促进空化作用的产生,空化泡破裂时能产生瞬时高压。根据这一特点,设计了冲洗-喷洒两用喷射器。直接采用市政管网自来水作为工作流体,引射掺入适量空气,实现高效清洗和绿化喷洒两种用途。Moderate air mixed into water fluid will accelerate the cavitation.When the cavitation bubbles crumble and fall,it will give birth to the instantaneous high pressure.According to this,we design the ejector for washing and spraying.The tap water is used as the working fluid and the atmospheric air is sucked into the water which results in the aerated flow to realize high efficency washing.With a tee joint we combine the ejector and a spray nozzle together.
