The air-jet exhauster is a compressed air-operated device for pump priming, provided that the pump has no foot valve. Water is induced into the pump by vacuum created by the exhauster.
以压缩空气为动力的气体引射器，它是用在无底阀水泵上的抽气引水设备，具有结构简单、加工制做容易、耗气量小、效率高等特点。
In the air-water back washing filter, application of jet pump instead of air compressor or blower can considerably save both the installation cost and the running cost.
用射流泵代替空压机或鼓风机进行滤池气水反冲洗、能大大降低设备和运行费用。
When the pump starts working, the self-priming process can be achieved, and the valve of water-ejecting will be shut off automatically to stop the working of jet flow system simultaneously.
泵运转时，不仅可以完成自吸过程，而且可以将自循环射流器上的阀门关闭，射流器同时停止工作。
