FGI Medium Voltage Drive to help overseas potassium mine main fan energy saving and efficiency
1.Quote
Potassium ore is mainly used for fertilizer production, as the main raw material of potash fertilizer. Potassium fertilizer is a common agricultural fertilizer, which plays an important role in promoting the growth of crops. In addition, potassium ore can also be used in the production of other chemical products, such as glass, soap and so on.
In the modern mine safety production system, the ventilation system is like the "lung of the mine", which undertakes the core mission of transporting fresh air, diluting harmful gases and ensuring the safety of the working environment. As the "lifeline" of potassium mine safety production, the main ventilator is in a state of high strength and continuous operation all year round, and its energy consumption accounts for 20%-30% of the total electricity consumption of the mine. However, the traditional power frequency driven fan system generally has the pain point of "big horse trolley" - the equipment runs at a constant speed for a long time, and the air volume cannot be dynamically adjusted according to the actual needs of the mine, which not only causes huge energy waste, mechanical loss and maintenance costs also rise. With its significant advantages of precise control, high efficiency and energy saving, frequency conversion speed regulation technology is bringing revolutionary upgrades to the mine ventilation system. By applying the high voltage inverter to the main fan drive system of potassium mine, the intelligent matching of motor speed and mine ventilation demand can be realized, and the energy consumption efficiency can be improved to a new height under the premise of ensuring safe production.
2.Project overview
A European chemical company is a large multinational fertilizer production and sales group, the company set nitrogen fertilizer, phosphate fertilizer production and potassium mine development as one, in the world has rich mineral resources, the company occupies an important position in the global fertilizer industry, is the world's third largest fertilizer company.
The company used to use other imported brands of 6kV9MW frequency converter, due to frequent failure problems affect its production, in order to ensure the production needs, it is urgent to replace the inverter transformation and provide related services.
3.Application condition
As the key equipment of mine ventilation system, mine main ventilator undertakes the important tasks of transporting fresh air to the mine, diluting harmful gas and regulating the underground environment. For a long time, the main fan of mine has some problems, such as high energy consumption, start-up difficulty and serious mechanical damage, which seriously affect the safety production and economic benefit of mine. Therefore, the use of frequency converter for the stable operation of the mine main fan is particularly important. The original imported brand frequency converter used by the customer had frequent failures, which seriously affected production. Since the first cooperation with FGI in 2022, FGI frequency converter has been running steadily at the site. In 2024, the customer proposed new requirements, FGI combined with the field operation conditions, for the project to recommend the customer for high-voltage and high-power water-cooled inverter solutions, to solve the customer's demand for production process.
4.Application performance
After the operation of FGI frequency inverter, after repeated testing, the operation parameters have been normal, safe and reliable, and the indicators have met the design requirements.
Seamless replacement of imported brands, the system is safe and reliable to ensure continuous load operation.
Simple maintenance and convenient operation.
The frequency converter seamlessly interfaces with the field signal to meet the needs of production.
