A water tank works by storing water and then releasing it on demand, typically utilizing gravity, pumps, or air pressure to deliver the water to its destination.
Here's a breakdown of the process:
-
Water Intake: Water enters the tank through an inlet pipe, often controlled by a float valve to prevent overfilling.
-
Storage: The tank holds a reserve of water, ready for use. The size of the tank determines the amount of water available.
-
Water Delivery: When water is needed, it exits the tank through an outlet pipe. The method of delivery depends on the type of system:
-
Gravity-fed: In this system, the tank is positioned at a higher elevation than the point of use. Gravity provides the necessary pressure to push the water through the pipes. This is common in elevated water towers.
-
Pump-operated: A pump is used to increase water pressure and deliver it to the point of use. Pressure switches often communicate with the pump to maintain a desired water pressure level.
-
Air-pressurized: Compressed air inside the tank forces the water out. This type of system typically uses a pressure switch to maintain proper air pressure.
-
-
Pressure Control: Pressure switches are commonly used to monitor and regulate the pressure within the tank or the delivery system. They communicate with pumps or valves to maintain the desired pressure.
-
Check Valve: A check valve prevents water from flowing back into the tank from the delivery system.
In essence, a water tank is a reservoir that stores water and utilizes various methods to release and deliver it to meet demand. The specific method of delivery and the presence of components like pumps and pressure switches depend on the application and the desired water pressure.
