1. Principle of the Non-Drawdown Complete Water Supply Equipment

1. The water supply pipeline of the pressure-free set equipment is directly connected to the municipal water supply network. Driven by the remaining pressure in the water supply network, the water is pressurized into the equipment's water supply pipeline. The booster pump of the equipment continues to increase pressure based on the remaining water pressure, raising the water supply pressure to the level required by the user and then supplying it to the outlet water network.
2. When the water usage exceeds the supply from the public water supply network, the pressure in the intake pipeline drops. Once the pressure at the equipment's intake falls below 0, the negative pressure prevention and control device within the equipment automatically activates, adjusting the equipment's operating status until it shuts down and awaits further instructions. This ensures that the pressure in the intake pipeline does not decrease further, thereby avoiding negative impacts on the public water supply network.
3. Upon restoration of the municipal water supply system's capacity and when the incoming pipeline pressure recovers above the protective pressure, the equipment automatically starts and resumes normal water supply. When the remaining pressure in the municipal water supply system meets the user's water supply requirements, the equipment automatically enters a sleep mode, with direct water supply to users from the municipal water supply system. If water supply is insufficient, the equipment automatically resumes operation.
4. When users do not use water or use very little, the equipment automatically enters a shutdown sleep mode, with a low-flow pressure maintenance tank located on the equipment's water outlet side to maintain water usage for users and pipeline leaks. If the user's water pressure maintenance tank cannot maintain the required pressure for the water supply network, the equipment automatically wakes up and resumes normal operation. During operation, the equipment fully utilizes the remaining pressure in the water supply network, always ensuring it neither adversely affects the water supply network nor fails to meet user needs to the fullest extent, thereby reducing water supply energy consumption and achieving efficient operation of the water supply system.
