What if there is no electricity in the automatic circulating water system? Used in fish tanks.

Automatic circulating water system mostly uses electricity, and without electricity, it can only be semi-automatic. Now let's look at the semi-automatic circulating water system:

Preparation materials: 1 tee, two mineral water bottles almost as high as fish tanks, and several straws.

Operating steps:

1. Prepare two mineral water bottles about the height of the fish tank.

2, one horizontal and one vertical glass glue, do not need to get through, directly paste;

3. Prepare a tee, as shown in the yellow part of the figure, and glue it on the vertical bottle with glass (the upper part of the tee can be covered with a cover to control the water flow);

4. Prepare a straw with one end installed on the other side of the tee and the other end installed in a horizontal bottle (as shown in the figure) and fixed with glass glue;

5. On the horizontal bottle, that is, one centimeter away from the white straw, a straw of about 2cm is embedded (it is used to suck the water in the water tank and needs to be taken over);

6. Cover the white straw with a straw that can cover the (white) straw (as shown);

7. Put the glued white straw into an upright bottle and glue it with glass;

8. Put a straw on the straw just embedded in the bottle mouth and stick it with glass glue, as shown in the figure;

9. After completion, you can put the water to be changed in a vertical bottle, connect the left suction pipe to the pipe of the water tank, unscrew the tee, and suck the white suction pipe on the bottle vertically until the white suction pipe comes out, and it can be automatically circulated;

10, this is an automatic circulating water system.

Extended data:

The principle of automatic circulating water without electricity is that due to the existence of friction, water will gradually lose its kinetic energy in circulating flow. Without external energy, water can't keep circulating.

Since electricity is not allowed, we can turn to wind energy. There may be many principles, one of which is to use wind energy to drive the windmill to rotate, and the wind energy is converted into mechanical energy, and the mechanical energy generated by the windmill drives the propeller in the water, and the propeller pushes the water body to make the water flow.

There are mainly two kinds of circulating water, industrial and domestic, and the main purpose is to save water. Industrial circulating water is mainly used in cooling water system, so it is also called circulating cooling water. Because industrial cooling water accounts for more than 90% of the total water consumption. Domestic circulating water is mainly used for water heaters.

Cooling water system The system that uses water to cool the process medium is called cooling water system.

There are usually two kinds of cooling water systems: DC cooling water system and circulating cooling water system.

Preheated circulating water can be roughly divided into four categories:

1, remote control panel (remote control through wall);

2, water control version (water popular);

3. Computer board (fully automatic);

4. Mechanical board (semi-automatic);
