Secondary water supply equipment, generally located in the ground or basement. Units with water supply equipment for medical pure water can use this equipment to dispatch peak water consumption, increase water pressure, and meet large area water consumption and high-rise water consumption during peak water consumption. Units, factories or villages without tap water only need to connect the equipment to the source power supply, so as to obtain stable water volume and pressure to meet the needs of water use. Secondary water supply equipment is composed of air pressure tank, water pump and chemical industry water equipment and electronic control system. Its outstanding food water use equipment benefits from no need to build water tower, small investment, less land occupation, flexible organization and quick commissioning. Water and gas automatic dispatching, automatic operation, energy saving and automatic connection of tap water are selected. Water is still available after power failure, and there is no need for guard after commissioning. It is widely used in production, daily and operation water supply of enterprises, vertical tower-less water supply residential areas and villages. It is suitable for water supply households with daily water supply of less than 3000 m3 and water supply height of more than 100 meters.

Air pressure water supply is selected for secondary water supply equipment. The purpose of water supply is achieved by using sealed tank and high pressure gas-water pressure in the tank. Specific operation is to pump water into the tank through the check valve, so that the gas in the tank is compressed, pressure gradually increased. When the pressure reaches the specified upper limit, the electric contact pressure gauge automatically connects the pump through the control cabinet. The water pressure in the equipment is higher than that in the external pipe network, and the water is automatically sent to the water supply network. When the water level in the tank decreases and the gas swelling pressure in the variable frequency constant pressure water supply tank decreases to the specified lower limit position, the electric contact pressure gauge of the pneumatic water supply equipment restarts the pump through the control cabinet. Such repetition makes the equipment supply water continuously. When the gas in the tank is short, the filling valve can automatically fill the gas.
