As shown in the figure, the water head difference is set as the meter _below H, and the maximum pumping height is set as the meter _above H. The upper water tank and the pressure conversion tank are closed water tanks, which are only communicated with the pipeline.

According to the principles of fluid mechanics:

P _A = γ _water · _H

P _B =P _A -γ _gas · H= _γwater · H _up

So γ _water · H _up = γ _water · H _down - γ _gas · H

是A、B两处的压强。γ_水、γ_气是水和空气的重度。 In the formula,

is the pressure at A and B. γ _water , γ _gas is the gravity of water and air.

_Under H is the water head drop, referred to as the water head difference. _H is the pumping height. H is the height of the gas in the tube, referred to as the gas column height.

Since the γ _gas is very small, the γ _gas · H is ignored.

Then γ _water · H _up = γ _water · H _down , that is, H _up = H _down

This means that the pumping height is equal to the water head drop, and the pumping height here is the maximum pumping height. Below the highest point C of pumping water, any part of the pumping pipe is opened with a small hole, and water will flow out. During the process of water flowing out, the water in the water source tank is continuously flowing into the pressure conversion tank, and the compressed air in the pressure conversion tank flows to the upper water tank, pressing the water in the upper water tank into the water pipe to flow out until the pressure is converted The air in the box is completely exhausted, and the process of water flowing outward from the small hole of the water pipe stops slowly. Here it is the water-lifting principle of the pressure conversion of water pressure air and air pressure water.

Double-cylinder water lifting is adopted, using two pressure conversion tanks and two upper water tanks. The two pressure conversion tanks are supplied with water through the water source tank. Each pressure conversion tank is connected to a corresponding upper water tank. The steps of double-cylinder water lifting are as follows:

1) After pressing the start button, open the air release valve and air release valve B. After 1 s, the water inlet valve of the water source tank, the water inlet valve of the upper water tank, and the water inlet valve B of the upper water tank are opened, and the upper water tank, upper water tank B and The water source tank becomes a connector, and water flows into three containers. When the limit sensor B switch of the upper water tank and the sensor B of the pressure conversion box are turned ON, the water inlet valve of the water source tank, the water inlet valve of the upper water tank, the water inlet valve B of the upper water tank, the air release valve and the air release valve B are all closed.

2) After 1 s, the water valve is opened, and after 1 s, the water inlet valve of the pressure conversion box is opened, and the water in the water source tank enters the pressure conversion box along the downpipe to compress the air there. the

3) After 10 seconds, the air pressure valve, water outlet valve and water inlet valve of the water source box are opened. Open the water inlet valve of the water source box to maintain a stable water head difference, and water will flow out of the water pipe soon. This process converts the gravitational potential energy of the water into the pressure energy of the gas. the

4) After 140s of continuous pumping, the sensor of the pressure conversion box turns ON and the water in the upper water tank is about to reach the lower limit, and the water inlet valve B of the pressure conversion box is opened. the

5) After 10s, open the pressure valve B and the water outlet valve B, close the water inlet valve and the water outlet valve of the pressure conversion box, at this time, the upper water tank B and the pressure conversion box B are working, the upper water tank and the pressure conversion box stop working, and the water lift pipe Keep flowing. the

6) At the same time as step 5, the water inlet valve of the upper water tank is opened, and the upper water tank is replenished to prepare for the next cycle. The water discharge valve and the pressure valve are opened. When the limit sensor of the upper water tank turns ON, the water inlet valve of the upper water tank is closed; When the limit sensor of the pressure conversion box turns ON, after another 2s, the pressure conversion box is emptied, and the water discharge valve, air pressure valve and air release valve B are closed. the

In the same way, when the water tank 1 is emptied and the sensor B of the pressure conversion box turns ON, the operation of the next cycle starts again, and the steps are the same as the above steps. Realize double-cylinder type water lifting thus. the
