Watering cans is used for a wide range of purposes, such as watering flowers and fertilizing, but many people don’t know how to use hand-pressing watering cans, and hand-pressing watering cans are not easy to operate. The following article will tell you why you are using hand-pressing watering cans. When there is no spray water.
Problem description: The newly bought watering can sprays mist after tightening, but I need to spray water! Just press the button to spray a jet of water!
The best answer: Air-pressure spray can, not mist or water, it should be pressurized to spray like
Method 1: Maybe the water nozzle of the watering can be blocked, or the airtightness of the piston is not so good, and then it will not be able to generate enough negative pressure. When you feel the pressure is too large, you can clean it with a needle When you click on the spray nozzle, you can’t feel the pressure when you press it. That means the piston mechanism is broken and needs to be replaced.
The best answer is to reduce the water outlet diameter and increase the water pressure to increase the water outlet speed. Please check if the watering can you bought can be pressurized manually? If not, I’m afraid I can only get one or replace a nozzle. Choice of the nozzle outlet.
Method 2: It is also possible that the water in the watering can is too full. Pay attention to leaving a little air inside, so that the air pressure can spray the water pressure up. Remember to leave some air, and the water should not be too full, or You have not tightened it, you must tighten it very tightly to press out the air pressure.
When the piston quickly advances to the right, the air in the cylinder quickly flows out of the nozzle barrel, causing the air pressure in the nozzle barrel to decrease. Under the action of atmospheric pressure, the water rises in the suction pipe and finally flows out of the nozzle barrel. It is impacted by the airflow. Spray into a Foggy.
Introduction of the watering can: A watering can refer to a pot that holds water and waters flowers. The water spraying part is like a lotus with many small holes.
The best answer is that there is water leakage at the pressure rod of the pressure spray can, which is usually caused by a piston leak, just change the oil
1. Unscrew the watering can, unscrew the thick tube (that is, the air pump), and remove the rubber ring on the head (usually translucent);
2. Lubricate the previous waste
Expansion data: Air pressure is the atmospheric pressure acting on a unit area, which is equal to the weight of a vertical air column extending up to the upper boundary of the atmosphere on a unit area. The famous Magdeburg hemisphere experiment proves its existence. The system unit is Pascal, abbreviated as Pa, and the symbol is Pa. The reason for its formation is known from the molecular kinetic theory.
The pressure of a gas is caused by a large number of molecules frequently colliding with the container wall. The collision time of a single molecule on the container wall is extremely short, and the effect is not continuous, but a large number of molecules frequently collide with the wall, and the force on the wall is Continuous and uniform, the ratio of this pressure to the wall area is the pressure strength.
