The pressure of tap water is usually several kilograms. How is the pressure guaranteed? What equipment is usually used (what pump is used at the water outlet) to ensure it? How much pressure does an average county-level city face? This post was last edited by chenhao0713 on 2009-3-24 10:19 ]
The pressure of tap water is usually 0.2-0.3MPa, and the pressure can be guaranteed through a constant pressure variable water supply system.
The tap water pressure at the county level is related to the water supply height, water supply distance, resistance loss along the road, etc. This requires a strict calculation and cannot be estimated.
The tap water pressure is generally maintained at about 2 kg. It relies on a constant pressure water supply system to ensure that there is no pressure drop. It mainly uses a pressure transmitter, PID setter PLC, etc. to control the variable frequency output of the water pump.
Just use a centrifugal pump for tap water! Constant pressure!
There is a pumping station in a certain area, which uses a water pump to maintain a constant pressure of 2 to 3 kilograms.
Generally, centrifugal pumps are used to discharge water, and the speed of the water pump is adjusted through a frequency converter to achieve constant pressure water supply. The exact amount of pressure depends on the specific pipe network conditions.
