Application of frequency converter in double girder driving
Driving is a kind of lifting equipment widely used in industrial and mining enterprises. However, the traditional driving control system has high energy consumption, high overall equipment failure rate, high maintenance costs, low power factor of the power grid, and poor speed regulation accuracy, which has been difficult to meet the requirements of modern energy-saving, stable and high-performance equipment. Modern frequency conversion technology is applied to driving equipment, which can realize the main circuit contactless control, small starting current, low noise, accurate walking lifting positioning, high production efficiency, low maintenance cost, and complete frequency converter protection functions, which can effectively protect themselves, motors and other components.
Process features
The starting torque is large, and it can quickly accelerate and decelerate, forward and reverse
Multi-speed can be achieved and the speed is adjustable
When heavy load, the start and stop in the middle of the air is normal, stable, and does not slip
It can adapt to long-term frequent start-stop, forward and reverse rotation and jog control
Stepless speed regulation can be realized
The security protection is complete
Application scenarios
Walking mechanism: optional Senkuo SKF 8000 series inverter, the use of one drag multiple control, drag cart and trolley traveling mechanism, 15kW and below standard built-in brake unit, only need to configure brake resistance can achieve fast and smooth start and stop, so that heavy objects move smoothly and safely.
Lifting mechanism: Senkuo SKF 8000 series crane special frequency converter is selected, including special timing control for lifting, open-loop vector control, and the use of brake unit and brake resistance combined with mechanical braking to ensure smooth and reliable lifting with load.
Three-phase vector inverter
Senkuo inverter advantages
The fast current limit function effectively limits the inrush current and prevents frequent overcurrent protection
The powerful overload capacity can fully adapt to long-term frequent start-stop control: 180% rated load 3S
Ultra-fast torque response speed and stable speed accuracy, fast operation, accurate positioning, improve work efficiency
The special control logic of the crane can ensure that there will be no slippage phenomenon when starting and stopping at any position when fully loaded, and the driving operation is safe and reliable
It can reduce the power capacity requirements of driving, reduce the starting current, and improve the power factor of the equipment
