Abstract
The utility model relates to a variable -frequency and constant -pressure water supply system. Variable -frequency and constant -pressure water supply system adopts linear control strategy, because water supply system's essence is non -linear, these tactics can only be helpful at linearisation point neighborhood. The utility model discloses a pump electromotor, pressure sensor, controller, converter, water supply pipe, pond and pool water level sensor, water supply pipe draws forth from the pond, is provided with many pump electromotor on the route, meets with same platform converter, the last pressure sensor that installs of water supply pipe installs the pool water level sensor in the pond, pressure sensor, pool water level sensor, converter and pump electromotor all carry out the data interaction through communication line access controller. The utility model discloses a control to the converter realizes the control to the output water yield to reach constant pressure water supply's purpose, can better realize the control to the system under different work condition, realize simply controlling effectually.
Description
Technical field
This utility model relates to a kind of constant pressure water supply system, is specifically related to a kind of 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.
Present most of constant pressure water supply systems use linear control strategies, and the essence yet with water system is nonlinear, and this control strategy can only have certain effect in linearisation neighborhood of a point.
Summary of the invention
The purpose of this utility model is to provide a kind of constant pressure water supply system, can control ductwork pressure effectively, accurately and rapidly, reach the purpose of constant pressure water supply.
The technical scheme that this utility model is used is:
A kind of constant pressure water supply system, it is characterised in that:
Including pumping motor, hydraulic pressure sensor, controller, converter, water supply line, pond and water level in water pool sensor；
Water supply line is drawn from pond, and water supply line path is provided with multiple stage pumping motor, and including resident for hydroelectric machine, fire fighting supply motor and standby motor, all pumping motors connect with same converter；
Hydraulic pressure sensor is installed on water supply line, pond is provided with water level in water pool sensor；
Hydraulic pressure sensor, water level in water pool sensor, converter and pumping motor all carry out data interaction by communication line access controller.
This utility model has the advantage that
This utility model is by the control to the output water yield of the control realization of converter, thus reaches the purpose of constant pressure water supply, more preferably can realize the control to system under different operating modes, it is achieved simply, control effective.
Accompanying drawing explanation
Fig. 1 is this utility model structure composition diagram.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in detail.
This utility model relates to a kind of constant pressure water supply system, including pumping motor, hydraulic pressure sensor, controller (controller selection standard Industrial Control Computer PLC), converter, water supply line, pond and water level in water pool sensor.
Water supply line is drawn from pond, and water supply line path is provided with multiple stage pumping motor, and including resident for hydroelectric machine, fire fighting supply motor and standby motor, all pumping motors connect with same converter.Hydraulic pressure sensor is installed on water supply line, pond is provided with water level in water pool sensor.Hydraulic pressure sensor, water level in water pool sensor, converter and pumping motor all carry out data interaction by communication line access controller.
After system is run, the data of hydraulic pressure sensor and water level in water pool sensor acquisition are sent to controller by communication line, after controller receiving data, calculate by contrast and send control signal to converter, thus control the output of pumping motor.Owing to the power of pumping motor determines the input water yield of pipe network, 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.Owing to controller also directly interacts with each pumping motor, therefore directly each pumping motor can also be carried out power control.
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.
