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.
Airoperated namely USES the airpump and the air valve control air current, the positive governing barometric pressure and the current capacity, enable the air to have the vibration.
