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.
- The FBD type fan blade adopts the three-dimensional flow design, assumes the wing twist type, the fan high efficiency working condition area is big
- The fan is well designed with advanced technology, and can run stably in high pressure and low flow area. The air supply distance is long, and the adaptability to complex roadway is strong.
- The fan can choose any type of FBD (II) or FBD (III) local fan.
- Reduce the workload of replacing fans after a failure
