Problems solved by technology
[0002] With the accelerated advancement of a well-off society, centralized housing, high-rise buildings and urban centralized water supply pumping stations are increasing, there is an ardent demand for energy consumption, drinking water safety and centralized management. At present, non-negative pressure equipment has become the mainstream of the market. Traditional non-negative pressure The pressure is composed of multiple main pumps, pressure-stabilizing tanks and control systems. The traditional steady-flow tanks and pressure-stabilizing tanks are designed to be cumbersome, occupy a large area, have ineffective effects, and the water pressure is not constant during the peak water consumption period.

Description
technical field [0001] The invention relates to a pressure-stabilizing water supply device, in particular to a full-frequency conversion intelligent multi-connection non-negative pressure water supply device and its control method. Background technique [0002] With the accelerated advancement of a well-off society, centralized housing, high-rise buildings and urban centralized water supply pumping stations are increasing, there is an ardent demand for energy consumption, drinking water safety and centralized management. At present, non-negative pressure equipment has become the mainstream of the market. Traditional non-negative pressure The pressure is composed of multiple main pumps, surge tanks and control systems. The traditional surge tanks and surge tanks are designed to be cumbersome, occupy a large area, have no obvious effect, and the water pressure is not constant during the peak water consumption period. Contents of the invention [0003] The first technical pro...
