Description
The utility model relates to a kind of water supply facilities, particularly a kind of frequency control water supply facilities.
Existing frequency control water supply facilities is by one group of water pump, the frequency converter of coupling control of pump action, the micro computer constant-voltage controller, pressure sensor, valve, pressure meter and control cabinet are formed, the organizational form of water pump and frequency converter is variable frequency pump of a general pump or variable frequency pump of many general pumps normally, during running, be that first water pump switched to the power frequency running by the frequency control running before second starting mode of pump, causing supplies water extraordinary time and supernormal pressure fluctuation occur once changing for everything, suddenly big or suddenly small and the concentrated hot water user of the water yield often appears in user side to be had sometimes hot and sometimes cold, even the accident of scalding, also damage to electrical network formation impact and to the electric appliance and electronic device easily.
The purpose of this utility model provides a kind of every pump and all joins frequency converter micro computer constant-pressure variable water supply facilities, makes pressure of supply water stable, eliminated the supernormal pressure wave phenomenon, and electricity saving and energy saving efficient is higher.
The technical solution of the utility model is: every pump is all joined frequency converter micro computer constant-pressure variable water supply facilities, frequency converter, micro computer constant-voltage controller, pressure sensor, valve, pressure meter and the control cabinet of each group water pump coupling control of pump action, be formed by connecting by water inlet pipe, water inlet manifold, water main and water distribution system house steward pipeline, it is characterized in that: every water pump and a frequency converter mate one to one, and every exit of pump is equipped with a pressure meter.
Configuration prevents that water hammer from reaching the small pressure vessel of stablizing hydraulic pressure in the above-mentioned pipeline.
Above-mentioned frequency converter, micro computer constant-voltage controller are arranged in the control cabinet.
Operating principle of the present utility model: water supply facilities is directly experienced the variation of waterline network pressure by being located at pressure sensor on total water service pipe, and become the signal of telecommunication and pass to the micro computer constant-voltage controller, sense signal value and setup pressure value are relatively calculated, export 0～10V anaiog signal then continuously and give frequency converter, frequency converter is according to the variation of its 0～10V anaiog signal, change frequency, pump motor changes rotating speed with its frequency change, reaches the constant-pressure variable water supply function.When experiencing pressure less than setting pressure, pump rotary speed improves, and output increases; When experiencing pressure greater than setting pressure, pump rotary speed reduces, and output reduces.
Now with two one to one water pump and frequency converter be the example explanation course of work: when waterline network begins water, it is lower than setting value that pressure sensor is experienced force value, and the signal of telecommunication is transferred to frequency converter 1 after micro computer PID constant-voltage controller relatively calculates
A, make water pump A by zero rotating speed soft start, water supply start is accompanied by and closes the net water supply volume and constantly increase, the water pump A rotating speed rated speed of going directly, the water yield also reaches the specified water yield.If this moment, the pipe network water supply volume also increased, after process under the pump operation condition postponed in tens of seconds, frequency converter 1
BWater pump B is supplied water by zero rotating speed soft start.Water pump A, B supply water simultaneously at this moment.When the water service pipe water reduced, it is higher than setting value that pressure sensor is experienced force value, and the signal of telecommunication is transferred to frequency converter 1 after micro computer PID constant-voltage controller relatively calculates
B, water pump B rotating speed is reduced, be accompanied by pass net water supply volume and constantly reduce, water pump B rotating speed will change to zero gradually, shut down.If this moment, the pipe network water supply volume also reduced, in like manner, water pump A rotating speed also will reduce gradually, and when the pipe network water stopped, after the delay several seconds, water pump A can shut down.
The utility model has the advantages that: 1, the frequency converter of every water pump configuration oneself, so every water pump all is a variable frequency starting; Having eliminated in the prior art general pump starting current fully forms electrical network and impacts and the electric appliance and electronic device is damaged.2, before second starting mode of pump, first water pump need not change in the frequency control running, so pressure of supply water is very steady during second pump variable frequency soft start, eliminated fully because of extraordinary time of appearance and the supernormal pressure fluctuation of supplying water, thereby guaranteed that user side the suddenly big or suddenly small and concentrated hot water user of the water yield can not occur danger sometimes hot and sometimes cold even that scald is arranged.3, because every water pump all is frequency converter soft starts, the pump motor starting current only is about 15% of a power current, so the electricity saving and energy saving effect is remarkable.4, configuration small pressure vessel can slow down starting mode of pump, stop and pressure of supply water fluctuation and waterline network water hammer effect, improves pressure of supply water stability, disposes high-precision pressure sensor simultaneously, makes pressure of supply water constant in setup pressure value ± 0.01MPa.5, be equipped with a pressure meter at every pump outlet, there was a mechanical failure and when causing not water outlet of water pump or not reaching pressure of supply water when water pump, because pressure of supply water is lower than setting value, can send warning through equipment after tens of seconds, can impel the staff to carry out the mechanical performance maintenance.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is structure of the present utility model and supply channel and control circuit schematic diagram.
As shown in Figure 1, embodiment comprises three water pump A, B, C, connects three frequency converters 1 of control of pump action respectively
