Abstract
The utility model relates to a nonlinearity frequency constant -voltage water supply system. Present most of frequency constant -voltage water supply system adopts linear control strategy, because water supply system's essence is non -linear, these tactics can only have certain effect in the linearisation neighborhood of a point. 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 pump electromotor on the water supply pipe route, the last converter that is connected with of pump electromotor, 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 all carry out the data interaction through communication line access controller. The utility model discloses a nonlinear 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 additive mixing 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 of pipe network water pressure is become difficulties.Not having good hydraulic pressure control method can cause that ductwork pressure fluctuates, even there are the accidents such as pipeline burst in the loss that can increase equipment.The water system of currently the majority adopts constant pressure water supply system, utilizes the controlling thus reaching to control the purpose of hydraulic pressure pumping motor of the control realization to converter.This control method can be completed in a relatively short time the adjustment to hydraulic pressure.
Present most of constant pressure water supply systems adopt 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 additive mixing 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 adopts is:
A kind of additive mixing 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, water supply line path is provided with pumping motor, pumping motor is connected to converter；
Water supply line is provided with hydraulic pressure sensor, pond is provided with water level in water pool sensor；
Hydraulic pressure sensor, water level in water pool sensor, converter carry out data interaction each through communication line access controller.
Pumping motor is at least provided with three, and respectively resident is for hydroelectric machine, fire fighting supply motor and standby motor, each connects independent converter.
This utility model has the advantage that
This utility model passes through the control to the output water yield of the control realization to converter, thus reaching the purpose of constant pressure water supply, it is possible to better realizes the control to system under different operating modes, it is achieved simple, controls 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.
A kind of additive mixing constant pressure water supply system that this utility model relates to, 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, water supply line path is provided with pumping motor, pumping motor is connected to converter.Pumping motor is connected with electrical network by converter, and the output of pumping motor is determined by the output of converter.Water supply line is provided with hydraulic pressure sensor, pond is provided with water level in water pool sensor.Hydraulic pressure sensor, water level in water pool sensor, converter carry out data interaction each through communication line access controller.
Pumping motor is at least provided with three, and respectively resident is for hydroelectric machine, fire fighting supply motor and standby motor, each connects independent converter.
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 controlling 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, according to the output water yield, the input water yield is controlled, it is achieved thereby that the control to water supply network pressure, namely realizes frequency-changing pressure stabilizing work.
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.
