Description
Technical field
This utility model relates to frequency conversion control technique field, particularly relates to a kind of frequency-changing pressure stabilizing energy-saving water supply system.
Background technology
The hydraulic pressure of major part provinces and cities official website can not meet the user of more than 6 layers at present, these users need to increase hydraulic pressure could meet water demand, in existing frequency-conversion water supply system, conventional principle is: after system start-up, by pressure sensor senses discharge pressure, when pressure is lower than setting value, variable frequency starting First water pump.When a water pump is not met by the pressure set, first transferred First water pump to power frequency operation (access civil power) by catalyst, converter is accessed second water pump simultaneously, carry out variable frequency starting water supply.When two water pumps are not met by pressure requirements, ibid program accesses the 3rd water pump and is operated, and meets pressure of supply water.When pressure exceedes arrival setting pressure, reverse operating successively, exits pump working number of units, meets client's requirement to pump capacity and pressure.
In existing frequency conversion control water system, only considered the number of units starting water pump, generally when previous water pump runs, with maximum (top) speed, the pressure still not reaching setting, open next water pump and get involved.If when First water pump power frequency operation, pressure remains without the force value reaching to set, but with the force value set is more or less the same, at this moment owing to First water pump is increased hydraulic pressure, second water pump needs (rotating speed is more high, and corresponding pressure is more big) to reach the frequency close with First power frequency, and ability opening installation is at the check-valves of pump outlet, carry out amount of makeup water, meet pressure requirements.According to frequency control pump characteristics it is recognised that variable frequency pump has speed adjustable range and the best operating point of the best.And when two water pumps are all when high power frequency work, two water pumps are not the reasonable intervals operating in water pump, cause the waste of electric energy.
The power supply power supply mode of existing frequency conversion control water system is powered mainly by municipal administration, within 24 hours, needing the user of water pump, it is meant that must flow through 24 hours unlatching civil powers and is powered, compares waste resource, do not reach energy-conservation purpose.
Existing water system adds defecator to meet the cleaning of watering at water inlet pipe place, however, it is desirable to defecator routine cleaning, cause the waste of certain wealth.

Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Illustrate that the utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
As shown in the figure, a kind of frequency-changing pressure stabilizing energy-saving water supply system, wherein, pressure transducer 1 is arranged on the outlet pipe of water system 2, the input module of PLC control system 3 is connected with the signal output part of pressure transducer 1, the output module of PLC control system 3 is connected with efficient mute type converter 4, man machine interface 9 is connected with PLC control system 3, electric power system is connected with PLC control system 3, the corresponding water pump 5 of each efficient mute type converter 4, water pump 5 one end is connected with efficient mute type converter 4, the other end is connected with the outlet pipe of water system 2, wherein the algorithm of PLC is PID, the number of water pump 5 is be more than or equal to two, electric power system is divided into mains-supplied 6 and solar powered.
Described solar powered include solar panel 7 and accumulator 8.
