Pressure Buffer: The primary function of a pressure tank is to store a volume of pressurized fluid, such as water or compressed air. This stored fluid acts as a buffer or reservoir. When the system experiences a sudden demand for fluid, the pressure tank releases the stored fluid to meet the demand without a significant drop in pressure. This ensures a consistent pressure level in the system.
Pressure Regulation: Pressure tanks are equipped with a pressure switch or pressure-regulating device that monitors the pressure within the tank. When the pressure drops below a certain setpoint (due to demand), the pump or compressor is activated to repressurize the tank. When the pressure exceeds a specific upper limit, the pump or compressor turns off. This on-off cycling helps maintain a constant pressure within the system.
Minimizing Pressure Fluctuations: Without a pressure tank, systems would experience significant pressure fluctuations as pumps or compressors turn on and off to meet demand. Pressure tanks smooth out these fluctuations, providing a steady and consistent pressure to downstream devices and users.
Even Distribution: In water supply systems, pressure tanks ensure that water is distributed evenly to taps and appliances. The tank allows for a controlled release of water, preventing sudden surges in pressure that can damage pipes or appliances.
Preventing Water Hammer: Pressure tanks help prevent water hammer, which is the shockwave created by the sudden stop or change in the flow of water. Water hammer can lead to pressure spikes that damage pipes and fixtures. Pressure tanks absorb these pressure surges, protecting the system from water hammer.
Extended Run Times: The presence of a pressure tank allows pumps or compressors to run for longer periods before cycling. Longer run times reduce the wear and tear on equipment and contribute to energy efficiency, as frequent starting and stopping consumes more energy.
System Stability: Pressure tanks enhance the stability of the fluid system by providing a constant supply of fluid at a set pressure. This is essential for various applications, including domestic water supply, irrigation, industrial processes, and pneumatic systems.
The pressure tank acts as a stabilizing component in fluid systems, preventing pressure fluctuations and maintaining a consistent pressure level. It does this by storing and releasing fluid as needed, regulating the operation of pumps or compressors, and safeguarding the system from pressure variations and water hammer effects. These characteristics make pressure tanks a valuable component in various applications where maintaining a steady and reliable pressure is essential.
