Advantages and application of frequency converter in driving system of pipe belt conveyor (2)

The advantages of frequency conversion speed regulation for pipe conveyor are: wide speed regulation range, large starting torque, slow starting under heavy load, high starting safety, good synchronous performance for multi-motor driving, and significant improvement of motor power factor. The converter can realize intelligent adjustment by setting parameters remotely by computer. At the same time, the frequency converter can improve the power factor, reduce the line loss of the bus, reduce the secondary current of the distribution transformer in the workshop, and the saved reactive current can be transferred to newly installed equipment in the power grid. At the same time, the reduction of reactive current can reduce the running temperature of power transformer, thus prolonging the service life of power transformer.

The existing flat belt conveyor generally adopts industrial frequency dragging, but the conveyor will be operated very uneconomically caused by long-term power frequency operation of the motor and the efficiency of the hydraulic coupling. At the same time, the motor starts and stops, causing a severe impact on the conveyor, accelerating the wear and tear of the conveyor. Besides, problems such as the abrasion and maintenance of the belt and the hydraulic coupling will bring a large amount of expenses to enterprises, which is inconsistent with the energy-saving society proposed now. The matching frequency converter of long-distance pipe belt conveyor is of great significance for saving social energy, increasing economic benefits of enterprises and realizing the vision of "Carbon Neutrality and Emission Peak " in the world.
