The PLC 39 controls the working state of each stage of the pneumatic pump by means of time division multiplexing, that is, the two reversing valves of each stage of the pump are reversed in a time division multiplexing manner. The working process is as follows:

At the beginning, the gas tank is closed. The PLC 39 provides the first reversing valve 33, the second reversing valve 34, the third reversing valve 35 and the fourth reversing valve 36 through four control ends 40, 41, 42 and 37, respectively, as shown in FIG.

As the pump body sinks, "water" enters through the first one-way inlet valve 17 at the bottom of the first container 1. To the first container 1, the air inside the first container 1 is introduced into the third container 3 as the "water" is continuously pressed. Since the first container and the third container correspond to two communicating closed containers, the water does not fill the first container due to the pressure of the air.

In the second embodiment, the three-capsule air bag 5 in the first container sequentially passes through the first air pipe 25, the inflation port 46 of the first reversing valve 33, the exhaust port 51 of the first reversing valve 33, the main line 55, The intake port 49, the inflation port 44, and the third air tube 27 of the third reversing valve are in communication with the three-capsule air bag 7 in the third container.

Since the three-capsule air bag 6 and the fourth in-tank air bag 8 in the second container correspond to two communicating closed containers, the water does not fill the second container due to the pressure of the air. At this time, part of the air in the air bladder 7 in the third container is discharged to the outside through the third switching valve 35.
