It is favored by users, especially in the past ten years, with the acceleration of urbanization and the construction of high-rise buildings, non-negative pressure equipment has been widely used as a new generation of secondary water supply system. The non-negative pressure water supply equipment can use the pressure of municipal water pipes for secondary superimposed water supply, which has obvious energy-saving advantages and can reduce investment costs. However, when the water pump has a small flow rate, its own operating efficiency is significantly reduced, and the constant-pressure water supply at the outlet is adaptable to changes in water consumption. Sex is poor. Studies have shown that the non-negative pressure water supply equipment in pure residential quarters operates in the small flow water supply range for 60% of the time, and operates in the near zero flow water supply range for 30% of the time. The efficiency of equipment operation is very low when operating in the range of near zero flow water supply. However, the current non-negative pressure water supply system basically cancels the high-level living water tank completely.

Therefore, It is necessary to innovate the configuration of the non-negative pressure water supply system and its control method according to local conditions (with the large-scale equipment) and time-to-time (with different water supply flow periods), otherwise the equipment will run in the low-efficiency area for a long time. Cause big energy waste.
