The utility model discloses regard as a system with whole water supply network twine, can save the water supply system energy and provide and stabilize the water source, realize simply, controlled strong.
Description
Technical field
This utility model relates to a kind of constant pressure water supply system, is specifically related to a kind of network constant pressure water supply system.
Background technology
Domestic water, water for industrial use and other result in the change at random of water consumption with the randomness of water.Therefore the effectively control to pipe network water pressure becomes difficulties.Not having good hydraulic pressure control method that ductwork pressure can be caused to fluctuate, even there are the accidents such as pipeline burst in the loss that can increase equipment.The water system of currently the majority uses constant pressure water supply system, utilizes the control realization to converter to control pumping motor thus reaches to control the purpose of hydraulic pressure.This control method can be completed in a relatively short time the adjustment to hydraulic pressure.
But present most of constant pressure water supply system is separate, system is easily subject to disturbance and loses stable.
Summary of the invention
The purpose of this utility model is to provide a kind of network constant pressure water supply system, control ductwork pressure that can be effective, stable, the most cost-effective.
The technical scheme that this utility model is used is:
A kind of network constant pressure water supply system, it is characterised in that:
Including controlling exchange and multiple water factories node, water factory's node includes for hydroelectric machine, converter, water supply line, flow transducer, pond and water level in water pool sensor；
Water supply line is drawn from pond, water supply line path is provided with for hydroelectric machine, has converter for connecting on hydroelectric machine；
Flow transducer is installed on water supply line, pond is provided with water level in water pool sensor；
Flow transducer, water level in water pool sensor, converter are all by communication line Access Control exchange；
It is also equipped with water supply line between pond between each water factory node, it is also equipped with for hydroelectric machine and converter in this water supply line upper pathway, being provided with hydraulic pressure sensor on this water supply line, between water factory's node, the converter on water supply line and hydraulic pressure sensor are by communication line Access Control exchange.
Each water factory node supplies hydroelectric machine, fire fighting supply motor and standby motor at least provided with three for hydroelectric machine, respectively resident, each connects independent converter.
This utility model has the advantage that
Whole water supply network is considered as a big system by this utility model, can effectively save the energy of water system and provide reliable and stable water source, it is achieved simple, controlling is strong.

Fig. 2 is water factory's node structure figure.
Fig. 3 is water factory's internodal association structure figure.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in detail.
A kind of network constant pressure water supply system that this utility model relates to, including controlling exchange (controlling exchange selection standard Industrial Control Computer PLC) and multiple water factories node, water factory's node is the waterworks in network.
Water factory's node includes for hydroelectric machine, converter, water supply line, flow transducer, pond and water level in water pool sensor.Water supply line is drawn from pond, water supply line path is provided with for hydroelectric machine, has converter for connecting on hydroelectric machine.Flow transducer is installed on water supply line, pond is provided with water level in water pool sensor.Flow transducer, water level in water pool sensor, converter are all by communication line Access Control exchange.
It is also equipped with water supply line between pond between each water factory node, it is also equipped with for hydroelectric machine and converter in this water supply line upper pathway, being provided with hydraulic pressure sensor on this water supply line, between water factory's node, the converter on water supply line and hydraulic pressure sensor are by communication line Access Control exchange.
Each water factory node supplies hydroelectric machine, fire fighting supply motor and standby motor at least provided with three for hydroelectric machine, respectively resident, each connects independent converter.
During operation, in single water factory node, the data of flow transducer and water level in water pool sensor acquisition are sent to control exchange by communication line, after controlling exchange reception data, calculate by contrast and send control signal to converter, thus control the output for hydroelectric machine.Owing to determining the input water yield of pipe network for the power of hydroelectric machine, it determines ductwork pressure with the output water yield, is controlled the input water yield according to the output water yield, it is achieved thereby that the control to water supply network pressure, i.e. realizes frequency-changing pressure stabilizing work.Between water factory's node, the data of the hydraulic pressure sensor collection on water supply line are sent to control exchange by communication line, after controlling exchange reception data, the converter calculated by contrast on water supply line between water factory's node sends control signal, thus control to supply on water supply line between water factory's node the output of hydroelectric machine, so, the water supply scheduling being achieved that between multiple water factories node, is controlled the pressure of supply water in whole network, it is achieved that the frequency-changing pressure stabilizing work of whole network.
Content of the present utility model is not limited to cited by embodiment, the conversion of any equivalence that technical solutions of the utility model are taked by those of ordinary skill in the art by reading this utility model description, is claim of the present utility model and is contained.
