Renovation of Constant Pressure Water Supply Equipment in Zhuozhou Waterworks Company

The constant pressure water supply equipment adopts pneumatic water supply. Using a sealed tank and utilizing the high-pressure gas water pressure inside the tank to achieve the purpose of water supply. The specific working sequence is that the water pump presses water into the tank through a check valve, compressing the gas inside the tank and gradually increasing the pressure. When the pressure reaches the upper electrical contact pressure gauge, the pump will automatically stop through the control cabinet. The water pressure in the equipment is higher than the external pipe network pressure, and it automatically sends water to the water supply pipe network. When the water level inside the tank drops and the gas expansion pressure inside the tank decreases to the lower limit position, the electric contact pressure gauge will restart the water pump through the control cabinet. Repeat this process repeatedly, causing the equipment to continuously supply water. When the gas in the tank is insufficient, the gas replenishment valve can automatically replenish the gas.
working conditions
1. Transport medium: Cold and hot clean, non flammable and non explosive liquid that does not contain solid particles or fibers.
2. Liquid temperature: Room temperature type -15 ℃ to+70 ℃ Hot water type+70 ℃ to+120 ℃
3. Surrounding environment: no water droplets, steam, floating dust or metal particles. Places without sunlight exposure, high temperatures, and severe dust accumulation. Non corrosive, flammable gas and liquid environments. A place with no vibration and easy maintenance and inspection.
4. Environmental temperature: maximum+45 ℃ and well ventilated.
