Abstract
The utility model discloses a kind of constant pressure water supply automatical control system, comprise protective gear, programmable controller PLC, router HUB, frequency variator, water pump and touch screen, described protective gear is protected automatical control system, prevent automatical control system from occurring overload, described programmable controller receives data and processes and send touch screen to, it is interconnected that described router HUB is used for realizing multiple subnet, described frequency variator changes output frequency according to the signal that programmable controller PLC is given, thus change the rotating speed of pump motor, described touch screen leads to can be monitored the state of automatical control system and the setting of automatical control system parameter in real time.The utility model have automaticity high, prevent automatical control system occur overload, device start steadily, the advantage mutually disturbed when miscellaneous equipment runs in electrical network can be eliminated completely.
Description
Technical field
The present invention relates to a kind of control electric installation, specifically belong to a kind of constant pressure water supply automatical control system.
Background technique
Constant pressure water supply system with pipe network water pressure (or user's water flow) for setup parameter, automatically the rotating speed of pump motor is regulated by the output frequency of Controlled by Programmable Controller frequency variator, realize the closed-loop adjustment (PID) of pipe network water pressure, make water system automatic constant surely in the force value set: when namely water consumption increases, frequency raises, pump rotary speed is accelerated, the corresponding increase of water output; When water consumption reduces, frequency reduces, and pump rotary speed slows down, and water output is corresponding reduction also, this ensures that theres the requirement of water application efficiency user to hydraulic pressure and the water yield, reaches the object improving water supply quality and water application efficiency simultaneously, " using how much water, for how much water "; Adopt this equipment not need to build elevated tank, water tower, water quality no secondary pollution is a kind of desirable modern architecture water supply equipment.
Summary of the invention
The object of this invention is to provide a kind of constant pressure water supply automatical control system; automatically the rotating speed of pump motor is regulated by the output frequency of Controlled by Programmable Controller frequency variator; realize the closed-loop adjustment of pipe network water pressure, and by protective gear, automatical control system is protected.
The technical solution used in the present invention is as follows:
A kind of constant pressure water supply automatical control system, comprise and there is protective gear, programmable controller PLC, router HUB, frequency variator, water pump and touch screen, described protective gear is used for protecting automatical control system overload, described programmable controller receives data and processes and send touch screen to, it is interconnected that described router HUB is used for realizing multiple subnet, described frequency variator changes output frequency according to the signal that programmable controller PLC is given, thus change the rotating speed of pump motor, described touch screen leads to can be monitored the state of automatical control system and the setting of automatical control system parameter in real time.
Described protective gear is arranged in main loop and branch road, carries out multiple protective to automatical control system, and specific aim protection, makes automatical control system safety and reliability.
Described programmable controller PLC adopts OMRON CH series, with the PLC of EPA interface, receives fast and transmit data.
Described router HUB adopts industrial ethernet protocol, carries out communication, realize multiple subnet interconnected to the equipment such as PLC and touch screen.
Described frequency variator adopts Siemens SIEMENS frequency variator, carries out communication by industrial ethernet protocol and PLC.
Compared with the prior art, beneficial effect of the present invention is as follows:
Automaticity of the present invention is high, employing variable-frequency control technique; protective gear carries out overload protection to automatical control system; service life of equipment in prolongation system; ensure stationarity during device start; the working life of equipment in system can be extended; adopt mutual self-shileding system, mutual interference when effectively avoiding equipment normally to run.
