when a user uses water, the water inlet pipe 2 automatically injects water into the non-negative pressure adjusting tank 1; meanwhile, the pressure of the water outlet end of a user is reduced, when the pressure of the equipment is reduced to the starting pressure of the pump, the equipment is automatically started to work, one water pump 4 is started, the equipment keeps the pressure of a pipe network constant by adjusting the rotating speed of the water pump 4, and when the pressure detected at the water outlet pipe 3 of the system is smaller than the starting pressure value of the equipment, the intelligent variable frequency control system can automatically adjust the rotating speed of the water pump 4 to make the outlet pressure constant; when the water pumps 4 run at the power frequency rotating speed but the pressure does not reach the set pressure, the system starts the other two water pumps 4 in sequence;
along with the reduction of the water consumption, the outlet pressure rises, the rotating speed of the water pump 4 is gradually reduced, if the rotating speed of the water pump 4 is reduced to the lowest rotating speed set by the system, the intelligent frequency conversion control system enables the three water pumps 4 to stop running in sequence, and the pressure of the pipe network of the water outlet pipe 3 is ensured not to be reduced any more, so that the adverse effect is caused on the tap water pipe network;

The residual pressure of the tap water pipe network is fully utilized in the running process of the equipment, so that the user requirements are met to a great extent without causing adverse effects on the tap water pipe network all the time, the water supply energy consumption is reduced, and the optimal running of a water supply system is realized.
The water supply equipment is totally enclosed, is directly connected with a tap water pipe network, supplies water to users intelligently, energy-saving and cleanly through a negative pressure eliminating mechanism and a non-negative pressure adjusting tank 1, removes a water tank and a water tank, and effectively avoids secondary pollution. The non-negative pressure water supply equipment fully utilizes the original pressure of a tap water pipe network, pressure superposition, difference and compensation are completed on the basis of the original pressure, so that the equipment is more energy-saving, and the equipment is produced by adopting food-grade stainless steel 304, is clean and sanitary, and is a secondary water supply method approved by the current market.
