Background technology:
Along with the sharp increase of skyscraper, constant pressure water supply equipment has become the equipment that must join, and the reliability service of constant pressure water supply equipment is the major issue that is related to people's life and personal safety and safety of property.But specialized maintenance personnel famine in order to cultivate high professional qualification specialized maintenance personnel better, must have the device of teaching and real training at present.And the student has only knowwhy now, and the unit that practical experience will go to have true large-scale constant pressure water supply equipment is visited and practice, and is not only time-consuming and inconvenient, and effect is also bad.Therefore, the constant pressure water supply teaching training apparatus becomes the device that cultivation constant pressure water supply equipment maintenance personal presses for.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of multiple functional, constant pressure water supply teaching training apparatus that practice teaching is effective, easy to use is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the constant pressure water supply teaching training apparatus, comprise constant pressure water supply control module, topworks and power distribution cabinet, the constant pressure water supply control module is provided with pressure transducer, frequency converter, PLC and converter, converter comprises contactor and relay, and topworks comprises water pump, water tank, connection water pipe and regulates the valve of hydraulic pressure; Pressure transducer with pressure signal transmission to frequency converter, frequency converter is according to pressure signal, regulate through the PID computing, output adds pump or subtracts the pump signal gives PLC, the action of PLC control contactor, by contactor control water pump operation, also be provided with FCM fault control module and be electrically connected with frequency converter, PLC, converter and power distribution cabinet again, FCM fault control module comprises several switches and corresponding connecting line.
The beneficial effects of the utility model are: owing to be provided with FCM fault control module, as long as the some switches of action, device just can not normally move, form a trouble spot, got rid of by the student, different switches is represented various fault, form practice teaching equipment, the utility model fault is provided with convenience, flexible, has authenticity, is the ideal device that improves maintenance personal's professional standards.
Description of drawings:
Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is a FCM fault control module electrical schematic of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Shown in Fig. 1-2, the constant pressure water supply teaching training apparatus, comprise the constant pressure water supply control module, topworks and power distribution cabinet 1, the constant pressure water supply control module is provided with pressure transducer 2, frequency converter 3, PLC and converter 4, converter 4 comprises contactor and relay, topworks comprises water pump 5, water tank 6, the valve 7 that connects water pipe and adjusting hydraulic pressure, connect water pipe and comprise water inlet pipe 8 and rising pipe 9, water inlet pipe 8 is connected to water pump 5 imports from water tank 6 bottoms, rising pipe 9 is connected to the top of water tank 6 from water pump 5 outlets, constitute the circulation system, valve 7 is located in the rising pipe 9, and present embodiment is provided with four water pumps; Pressure transducer 2 is located at the front end of the valve 7 of rising pipe 9, pressure transducer 2 with pressure signal transmission to frequency converter 3, frequency converter 3 is according to pressure signal, regulate through the PID computing, output adds pump or subtracts the pump signal gives PLC, and the action of PLC control contactor is again by 5 operations of contactor control water pump, also be provided with FCM fault control module 10 and be electrically connected with frequency converter 3, PLC, converter 4 and power distribution cabinet 1, the FCM fault control module 10 of present embodiment comprises 30 switches 11 and corresponding connecting line.Described FCM fault control module 10 also is provided with 30 malfunction indicator lamp 12 with switch 11 interlocks, and when certain switch of action, malfunction indicator lamp is just lighted, and shows the trouble spot.Also be provided with monitoring system 13 and be electrically connected with PLC, monitoring system 13 comprises uses the configuration software module, and equipment running status is monitored and observed.Power distribution cabinet 1 is provided with voltage table, reometer, frequency meter indication, also has the running status of signal lamp indication water pump, and switch and hand push button etc. constitute automatic or manual control.
The principle of work of constant pressure water supply teaching training apparatus is as follows:
1, manually operation
Press the button starting or stop water pump, can control the start and stop of four water pumps as required respectively.This mode is mainly for maintenance and use during frequency converter failure.
2, control automatically
Close behind the automatic switch, a pump motor energising is started, and frequency converter 3 output frequencies rise from 0HZ, and the PID program of regulating will receive the electric signal from pressure transducer 2 simultaneously, compare through computing and given parameter, change the output frequency of frequency converter 3.Not enough as pressure, then frequency rises, and behind 50HZ, PLC control changes this water pump into power frequency operation, and another water pump is carried out frequency conversion, the frequency converter output frequency rises gradually, reaches setting pressure up to hydraulic pressure, adds the pump process; Reduce as water consumption, then control procedure is just opposite with said process.If power supply has a power failure, system-down then, treat that power up is normal after, this system can resume operation automatically.
Frequency converter 3 passes through to change output voltage and frequency control pump operation speed, thereby changes output reposefully, unsteady flow amount energy saving water supply under the prerequisite that guarantees pressure.FCM fault control module 10 is provided with 30 breakdown switches, when certain switch motion, corresponding trouble spot just can be set, and makes system artificial fault occur, and the practitioner will search scope of failure by the analysis of failure phenomenon, and fault is got rid of the most at last.
