Electric Control System For Pump/ Fan (MV VFD)

TAG: FJDK main fan(pump)high-voltage frequency electronic control devices
Product number:FJDK main fan(pump)
Description

FJDK main fan(pump)high-voltage frequency electronic control devices(main fun online monitored control system )

Main function:

The products are used in the power supply voltage of the main fan to 6KV (Main Drainage) electric power supply, frequency converter can be measured according to the system air volume (flow), wind pressure and compare with wind volume (flow) and pressure set ,

with the automatic adjustment of motor speed, so as to to meet the needs of air volume (of water) requirements at any time with significant characteristics of high-performance, digital, power-saving effect.

Technology characters:

1、When fault occurs in the frequency converter, the system will automatically realize the switching from high-voltage VVVF speed-adjusting mode to starting mode of reactor by voltage reduced , when fault occurs in the fanner (pump), the back-up fan (pump)will be used automatically and quickly, thus effectively ensuring the fan non-stop machine for safe operation.

2、Device to monitor the motor temperature, bearing temperature, wind speed (flow), pressure (hydraulic) pressure, negative pressure etc. danamic parameters, also set alarm overrun. With the function of remote data communications, to provide a variety of real-time data of fan (pump) running for the mine automation platform through industrial Ethernet to realize remote monitoring for the fan (pump) on line at centralized control room , fault diagnosis and cooperation system to realize nobody on duty on-the-spot.

3、The content of input and output harmonic is only 2% which is under national standard, the power factor is up to more than 96%, it doesn't need power factor compensation and harmonic suppression devices.

4、The frequency converter has various protection function of under voltage, over voltage, over current, short circuit, radiation fin overheating, stall, etc.

FJDK-BT Low-voltage VF speed- adjusting cabinet

Main function:

The products are used in the power supply voltage of 380V or 660V to electric power supply of the main fan (Main Drainage), frequency converter can compare air volume and wind pressure measured with the air flow and pressure set to automaticly adjust motor speed , so as to achieve at any time to meet the needs of air volume (of water) requirements, The products have characteristics of high performance and digitization, with prominent result of economizing on electricity.

Technology features:

The fan (pump) can put into automatic quick-frequency operation when fan (pump) failure , which guarantee non-stop machine for safe operation.

2、Device to monitor dynamic parameters of the motor temperature, bearing temperature, wind speed (flow), pressure (water pressure) and negative pressure etc. also set alarm overrun. Remote data can be communicated, a variety of real-time data of fan (pump) can be provided

for mine automation platform through industrial Ethernet to realize remote monitoring and fault diagnosis for the fan (pump) at centralized control room. With the system, it realizes field no one on duty.

3、The frequency converter has various protection function of under voltage, over voltage, over current and short circuit, etc.

4、Soft-start can be achieved to avoid insulation aging due to the large starting current and mechanical impact caused by large torque which effects service life of motor and fan ( water pump), save the costs of maintenance
