Background
The water pressure of a general municipal water network is only enough to deliver water to the height of about 6 floors, and for buildings with more than twenty-high floors, the water pressure of the municipal water network is not enough completely, secondary pressurization is needed, the traditional secondary water supply is to deliver water to a roof water tank, and then water in the building is taken from the water tank, so that the construction cost is high due to a plurality of adverse factors, and the roof water tank is easy to be polluted and needs to be cleaned regularly.
Along with technical development, secondary water supply system slowly changes into the pressure-superposed water supply system who does not have high water tank, generally comprises negative pressure stationary flow jar of preventing and adds the frequency conversion working shaft of activestandby and add steady voltage gas pitcher and frequency conversion regulation switch board, and this kind of mode also has some not enoughly: the stationary flow jar is used for storing certain water yield and prevents that the water pump from directly sucking municipal water net and causing the water net negative pressure, and steady voltage gas pitcher is used for stabilizing the pressure on the user side water pipe, too little play the steady voltage effect, too big then occupy the volume, moreover, such secondary water supply system all is how much water the user uses, how much water the water pump sending, when the water consumption is less, frequency conversion water pump low-speed operation, combine centrifugal pump field general knowledge, when the water pump operates under the super small discharge, efficiency is also low, not only violate the theory with energy-conservation, and, inverter motor, frequency conversion control etc. all need great equipment input.
