Electric Control for Mine Water Drainage

I. Scope of application: 

The mine automatic drainage device is designed according to the demand of centralized control of water pump underground coal mine. The operation state and operation process of the equipment are automatically detected and automatically controlled through the decision control of industrial computer to achieve the purpose of energy saving, reducing labor intensity and operation cost, prolonging service life, which is meeting the centralized control and unattended functions.

The system integrates industrial control technology and modern software technology, ensures the stability and reliability of the system, and can be connected with the whole coal mine automation system as a subsystem of the whole coal mine automation system.

II. Main functional features:

1. A variety of protections are included to guarantee the water pump system automatic operation in safe and reliable.

2. Without human intervention, it can be controlled by local control box, to start and stop the water pump automatically according to the water level, automatically realize the alternation of the pump, make reasonable scheduling.

3. It can achieve manual maintenance function or automatic operation function, manual control has control priority to ensure that even if the system gets failure, it can also be manually controlled to the normal operation.

4. The system has good real-time performance and can monitor and control the operating conditions of each pump in real time.

5. The local centralized display control box and remote display controller have friendly man-machine display interface, which has simple operation and beautiful picture. It can dynamically display static parameters, such as water pressure, level, flow, voltage, current and so on, and can store dynamic and static parameters, historical curves and event alarm records, etc. It can query and print real-time trends and historical trends in any time period at any time.

6. The man-machine interface display content in rich,vivid, visualized with easy operation and understand.

7. Has the protection action alarm function.

8. A large number of control strategies are embedded in software, which can make different decisions according to the actual situation, which greatly improves the degree of automation and intelligence of the system.

9. According to the specific conditions of different periods, the operating parameters of the software can be adjusted to adapt to the complex situation and improve the adaptability of the system.

10. The system enables remote monitoring.

11. Has a third-party cooperative control interface, which could communicate with frequency drive, medium voltage switch gear, multi-function instruments and parameter reading and writing.

12. Equipped with explosion-proof intelligent camera, which can monitor, judge and alarm for the devices in the water pump room or monitoring area in real time through sound, image, signal and other items.

13. Has the functions of status data acquisition, automatic analysis and early warning.
