Medium Transportable: Clean Water, WastewaterSunchuan Pump Industry's Variable Frequency Water Supply Equipment consists of three main parts: an air tank, a water pump, and an electric control system. Its outstanding advantages include the elimination of the need for a water tower, with small investment, minimal land use, flexible arrangement, and quick commissioning. It features automatic water-gas regulation, operation, energy saving, and automatic integration with tap water supply. It can continue to supply water during power outages and does not require supervision after commissioning. It is widely used for production, living, and office water supply in enterprises, residential areas, and rural areas. Suitable for locations with up to 5,000 water supply connections, daily water supply volume of up to 3,000 m3, and a water supply height of over 100 meters.

Variable Frequency Water Supply Equipment Working Principle
The variable-frequency water supply equipment uses a pressure tank system. It utilizes a sealed tank to achieve water supply by utilizing the pressure of high-pressure air and water inside the tank. The specific working sequence involves the pump pushing water through a check valve into the tank, compressing the tank's air and gradually increasing the pressure. When the pressure reaches the set upper limit, the electrical contact pressure gauge, through the control cabinet, automatically stops the pump. The water pressure in the equipment is higher than the pressure in the external pipeline network, and water is automatically supplied to the water supply network. When the water level in the tank drops and the internal gas expansion pressure decreases to the set lower limit, the electrical contact pressure gauge, through the control cabinet, restarts the pump. This process repeats, ensuring continuous water supply.
