Problems solved by technology
However, the traditional frequency conversion water supply equipment uses a frequency converter to manage multiple water pumps in a unified manner. At the same time, only one water pump can be frequency conversion, and multiple water pumps cannot be frequency conversion at the same time. Therefore, when the pump efficiency is consistent, the traditional frequency conversion water supply The energy saving effect of the equipment is not ideal

The invention discloses a frequency conversion water supply method, which comprises an equipment base, a water inlet pipeline, at least three pressurized water pumps, a water outlet pipeline and a pressure stabilizing tank, and each pressurized water pump is arranged in parallel between the water inlet pipeline and the water outlet pipeline. The outlet pipeline is connected with the inlet of the pressure stabilizing tank; it also includes a pressure monitoring module, a frequency conversion control cabinet and frequency converters equal in number to the pressurized water pumps, and the frequency conversion control cabinet is connected to the pressure monitoring module and each frequency converter to obtain data and adjust equipment operation. This frequency conversion water supply equipment installs a frequency converter for each pressure water pump, and then manages the work of each pressure water pump through a frequency conversion control cabinet. On this basis, a new frequency conversion method can be optimized to realize a digitally integrated full frequency conversion water supply solution. The efficiency of the pressure water pump is balanced, so as to achieve a more ideal energy-saving effect. The invention is used in the field of water supply equipment.
Description
technical field [0001] The invention relates to the field of water supply equipment, in particular to a frequency conversion water supply method. Background technique [0002] At present, the pressurized water pump on the traditional water supply equipment has been difficult to improve the efficiency of the unit, even if the efficiency value is increased by 1%, it is very difficult. In the current field of secondary pressurized water supply for buildings, most of the pump motors must keep running at full speed for only 5% of the time, so there is no need for the pump to continue running at full speed after the full-speed work is completed, in fact, it will run at full speed for a period of time. Time, so this is also the reason why water pumps and water pump motors waste energy at this stage. [0003] Therefore, frequency conversion water supply equipment has also been developed. However, the traditional frequency conversion water supply equipment uses a frequency converte...
