Understanding Water Pumps Activated by Pressure Relief
What Kind of Water Pump Activates When Pressure Is Relieved?
A pressure-activated pump or a pressure switch-controlled pump is designed to activate when the pressure in the system drops. These pumps are commonly used in various applications, including irrigation systems, water supply systems, HVAC systems, and well systems. This article will delve into how such pumps work, their applications, and different types of pumps utilized in these systems.
How It Works
Pressure Switch: A pressure switch is an essential component in these systems. It monitors the pressure in the system. When the pressure drops below a preset threshold due to water usage or a leak, the switch closes, sending a signal to activate the pump.
Pump Activation: The pump then turns on to restore pressure in the system. Once the desired pressure is reached, the pressure switch opens, turning the pump off. This cycle ensures consistent pressure in the system, preventing overuse of the pump and ensuring reliable performance.
Applications of Pressure-Activated Pumps
Well Pumps: In residential well systems, the pump activates when water is drawn from the tank, causing a drop in pressure. When the water level in the tank recovers, the system resets and the pump deactivates.
Irrigation Systems: These systems can use pressure switches to maintain consistent water flow, ensuring that the sprinklers or drip lines operate efficiently at all times.
Booster Pumps: Booster pumps are used to increase water pressure in municipal systems when demand changes. Such pumps are typically found in areas with fluctuating water demands, such as during peak usage hours.
Types of Pressure-Activated Pumps
Submersible Pumps: Often used in wells, these pumps are submerged in water and are activated by pressure switches. They are efficient for deep well systems where the water level is below the pump.
Jet Pumps: Common in shallow well systems, jet pumps also rely on pressure switches to operate. They are designed to lift water from shallow depths and push it to a higher level.
