Mine Main Ventilation Fan System
The Solutions of Main Ventilator System Based on Intelligent Mine
Product Introduction
This product is mainly designed according to the full working condition of the main ventilator. In line with safety first,excellent performance, to reach full automation control according to the most advanced technology of automatic control, realizing the safety operation control of unattended operation for field equipment,and monitor the parameters of field ventilator operation in real time. The monitored data is uploaded to the mine centralized control center. With historical records of ventilator operation parameters.It can provide real-time warning of the equipment operating conditions, reminding timely maintenance of the equipment, and ensure the safe and normal operation of the system.
Application Scope
Suitable for coal mines, non-ferrous metal mines, cement factories,power plants, water plants, chemical plants,and other places that require ventilators.

Main Characteristics
1、Realize switching to another ventilator by one-click without gap (switch from running ventilator to the standby).
2、Automatic switch to another ventilator if the operation one is in fault(the malfunction ventilator could switch to the standby);
3、With various control mode, such as on-line, standalone, manual, automatic, overhaul, etc.
4、With remote diagnosis function;
5、It could realize reverse wind operation function.
6、To adjust the speed of the motor in real time acconding to the actual air volume and wind speed to achieve the rational allocation of air volume and wind speed;Adjust the air volume as needed to avoid waste.
7、Real-time monitoring of ventilator performance parameters, such as negative pressure, flow rate,ful/static pressure, full/static pressure efficiency, shaft power, etc.
8、Real-time monitoring of ventilator motor electrical parameters,including Voltage, Current, Power, and air volume, etc.
9、Real-time monitoring of equipment state parameters: Speed vibration intensity, fan bearing temperature,motor stator temperature and bearing temperature, with alarm of temperature over the limit.
10、Fault diagnosis and early warning: when the main ventilator is operating, abnormal parameters such as air volume,negative pressure,ventilator operation vibration,ventilator bearing temperature,motor bearing temperature, motor winding temperature, motor speed, voltage, current, power, throttle opening and stopping state, such fault information and diagnosis results are sent to the electromechanical chief, electromechanical deputy chief and so on by short message through the fault diagnosis and information platform;
11、Maintenance information reminder function: according to the regular maintenance cycle, send the regular maintenance item information to the relevant personnel in advance,and realize the regular maintenance information reminder function.
12、Communication functions: Ethernet, MPI PROFIBUS-DP,RS485, etc.

FJDK-Main Ventilator (Pump)Variable Frequency Electric Control——Main Ventilator (Pump) Intelligent Monitoring System
Product Introduction:
This product is used to supply power to the main fan (main drainage) motor when the power supply voltage is 6kV(10kV).The frequency conversion device can measure the air volume (flow, wind pressure)and set air volume (flow, wind pressure) In contrast, the motor's speed is automatically adjusted to meet the requirements of the required air volume (water volume) at any time,and it has the characteristics of high-performance,digitalization,and remarkable power-saving effects.
Main Characteristics:
1、When the medium voltage VPD fails, the system automatically completes the automatic switch from high voltage speed control mode to reactor step-down start mode. When the fan (pump) fails, the backup fan (pump) can be automatically activated and quickly put into operation to ensure continuous safe operation.
2、This device can monitor motor temperature, bearing temperature,wind speed (flow), wind pressure (water pressure), negative pressure,and other dynamic parameters, and can set alarms beyond the limit.Remote online monitoring and fault diagnosis of the fan (pump) from the central control room, with the system to achieve an unattended site.
3、Input and output harmonic content is only 2%， lower than the national standard(4%), and power factor up to more than 96%, without a power factor compensation device and harmonic suppression device.
4、The VFD has various protection functions such as under voltage,over-voltage,over-current, short circuit, heat sink overheating, lost speed, etc.
