How to use pressure watering can

Spitter is also called pressure sprayer. The use of pressure watering can is very simple. First, water is poured into the pot, then the piston part is pressed by hand, and air is pumped into the pot, so that the liquid in the pot is pressed into the tube. Then aim at the place where water needs to be sprayed and press the watering can. When using the watering can, be careful not to add more water than the water level line. Pour out the liquid in time after use, and the situation is quiet. When not in use, release the pressure in the pot. Let's take a look at the usage and precautions of watering can. First, how to use the pressure watering can

Pressure watering can is what we often say. Its working principle is to use the high and low water level to generate pressure difference, and high pressure makes water spray out. The nozzle part has many small holes like lotus flowers, so the spray is in the form of water mist. So how to use the pressure watering can?

1. Pour water or medicine into the watering can and stop at the water level.

2. Press the piston by hand. At this time, it is pumping air into the pot. The air above the liquid level in the pot increases, and the pressure increases, which is greater than the external atmospheric pressure, and the liquid in the pot will be pressed into the tube.

3. Press the watering can where it needs watering, and the liquid inside will be sprayed out in the form of water mist and spread.

The above is how to use the pressure watering can. In the process of using the pressure watering can, there are still some aspects that need to be paid attention to in order to better use and avoid damage. What are the precautions when using watering can?

Second, the watering can instructions matters needing attention

1. When filling the watering can with liquid, be careful not to add too much water, whether it is clear water or other liquid components. Usually it is enough to add water to half, because it is easy to damage the nozzle if it exceeds the highest water level.

2. If the watering can't spray water during use, the small hole may be blocked by dirt or sand, so you can clean the nozzle in time.

3. When the watering can is not used temporarily, the pressure in the can should be released to avoid damaging the piston.

4. After the watering can is used up, if there is still liquid left in it, it is necessary to pour out the water in the pot, clean the watering can and keep it well.

5. When the watering can is used for a period of time, the piston can't feel the pressure, which may be the loss of piston gasket. At this time, you can unscrew the piston, change a gasket or cut a rubber sheet according to the shape of the original gasket for installation.
