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。

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。
