Product Description
System overview
The intelligent local fan ventilation system is a stable and reliable mine ventilation monitoring system.
The remote control of the fan is achieved and the parameters of the fan are monitored online so as to achieve over-limit alarm.
Through the downhole sensor feedback parameters to determine and adjust the amount of air supply thus solve the problem of mine local fan on demand.
To achieve safe, efficient, automatic, rapid discharge of gas, energy saving and electricity saving
When the main air supply circuit fails, the system automatically puts the backup circuit fan into operation, ensuring continuous air supply at the working surface
The composition of the system
The system is mainly composed of the following six parts
Main parameters of the system
Three gas sensors t1, t2, t3, realize the detection of gas concentration signal throughout the tunnel, the fuzzy controller simulation calculation control signal, change the output air volume, and gradually approaching the operating point, to ensure that the gas concentration at the confluence of the wind in the specified safety value below, to achieve the maximum efficiency of gas emission without excess. Double fan type automatic speed control device for double power input, the internal realization of double power automatic

switching, control of the main, standby fan of non-stop operation ,to ensure uninterrupted ventilation of the roadway
- The automatic speed control device adopts advanced SPWM frequency conversion technology, fast CPU fuzzy control technology and super-heat pipe cooling technology
- The speed control device has three operating modes: "automatic ventilation system", "automatic gas exhaust mode", and "manual frequency setting mode"
- Control function of running status: parameter peripheral function; automatic display of parameters and running status; power failure memory; wind power self-locking and gas power self-locking functions
- Achieve soft start, reduce the impact of starting current on the grid and fans, and extend the service life of fans and wind turbines
- The inverters of the main fan and the standby fan adopt an integrated structure, which can be connected to the main power supply and the backup power supply at the same time, and the structure is compact.
- Power dual fan automatic switching function; ventilation and exhaust gas state automatic operation and conversion function; fan forward and reverse switching function.
- The air volume is adjustable to prevent a wind blowing phenomenon. Significant energy-saving effects and short payback period for energy-saving investments.
