We have investigated and made the models of air-operated pulse pump since 1976. The theory suggested have been basically proved by the repeated tests and measurements.

1976年以来，我们研制了气脉冲模型泵。通过反复试验及性能测试使理论基本得到证实。

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。

Air operated namely USES the air pump and the air valve control air current, the positive governing barometric pressure and the current capacity, enable the air to have the vibration.

气动即采用气泵和气阀控制气流，直接控制气压和流量，使得空气发生振动。
