Application case of FGI FD370 Special Frequency Converter for Lifting in the mining industry
Every time the ore is lifted and every piece of equipment operates, it is directly related to production efficiency and personnel safety. As the core guarantee of the lifting industry, the safety and reliability of equipment have always been of Paramount importance. The latest FD370 series of frequency converters for special cranes launched by FGI integrates torque and speed, and is specially designed for harsh working conditions such as mine hoisting. This frequency converter provides a stable and reliable control solution for lifting equipment through multiple protection designs and excellent expansion performance. Nowadays, it has performed outstandingly in the practical application of a certain mining machinery in Hebi, providing reliable support for the intelligent operation of mining equipment.
2.Core technologies empower efficient operation
In the motor drive industry, the FD370 series frequency converter can precisely handle both asynchronous AC induction motors and permanent magnet synchronous motors with ease and confidence. The working process of its internal main circuit is "AC-DC-AC". The rectifier takes the lead and efficiently converts three-phase AC power into DC voltage. The capacitor bank in the intermediate circuit immediately intervened, as stable as a rock, ensuring that the DC voltage remained stable without fluctuations. The inverter is the final pressure shaft, precisely inverting the direct current into the driving voltage required by the motor. When the voltage fluctuation exceeds the safe range, the braking tube responds instantly and quickly connects to an external braking resistor to safely release the excess energy, ensuring the stable operation of the system at all times.
3.At the scene in Hebi, witness the blooming of strength
In a mining machinery factory area in Hebi, Henan Province, a 185kW FD370 series frequency converter is under intense debugging. At the commissioning site, technicians are fully concentrated. They are well aware that the precise adjustment of every parameter is related to the safety and efficiency of the future mine hoisting equipment.
The factory area's debugging and supporting control consoles are neatly arranged. The simulated winch hoisting site's brake device is constantly being tested to ensure that the intelligent control function of the brake is foolproof: before releasing the brake, it automatically validates the current/torque, and in case of abnormality, it applies emergency braking, completely eliminating the risk of the vehicle rolling back.
The hoisting system of Hebi mine has extremely high requirements for the reliability of equipment. The FD370 series frequency converter, with multiple limit protections, realizes emergency stop of upper and lower limit positions and automatic speed reduction in the slow zone, allowing for precise control of the working range. The automatic current limiting function in case of overload and the real-time monitoring function of motor temperature provide a dual guarantee for the service life of the equipment and the safety of personnel. After the debugging is completed, the fully prepared products are about to be dispatched to the front line of the mine. With their outstanding performance, they will assist a certain mining machinery in Hebi to carry out the mine hoisting operation efficiently and safely.
The FGI FD370 series frequency converters enhance the "hard" power of the industry with their "soft" strength. Whether it's functional customization, environmental adaptation, or expansion flexibility, we safeguard your devices!
