A pressure tank is used to control not only surges in the water and number of start cycles a pump runs per day, but primarily to force the pump to run for a certain period of time prior to shutting off, thereby getting the motor the cooling flow it requires. When water leaves the pressure tank and the pressure level drops below a certain point, the pressure switch turns on, allowing the pump to pull more water into. Pump control boxes are responsible for monitoring the flow of water and controlling a water pump to keep it at the desired level.
The constant pressure performance allows a 10psi differential for city like water pressure. This article describes and identifies the switches, controls, and safety devices used on water tanks and water pumps such as the pump pressure control switch, pump motor relays, water tank relief valve, water tank pressure gauge, water tank air volume control, and water tank air valve. As water is pumped from the well into the pressure tank, it compresses the air in the tank until it reaches a preset level, typically the 40 to 60 pounds per square inch (psi).
Adjustable from 10 to 80 psi. When the mud pumps are turned off for connection, the frictional pressure in the annulus is lost and pressure in the well bore decreases. (4) provide minimum flow to replenish the pressure.
