Information
Revamping equipment: air preheater main motor 45KW altogether 4 sets - changed to DYT limited torque permanent magnet coupling
Reasons for modification: The original design adopts hydraulic coupling transmission. The hydraulic coupling needs regular maintenance and repair, the maintenance and disassembly of motor is inconvenient, and the maintenance work is large and cumbersome.
The purpose of transformation is to reduce the amount of maintenance work of equipment, simplify the disassembly and assembly procedures of motor maintenance, and improve the maintenance efficiency of maintenance personnel.
Summary of modification: When hydraulic coupling is used, the starting current of motor is 3-4 times of rated current. When permanent magnet coupling is used, the starting current of motor is controlled about 2 times of rated current, and the duration of peak starting current of motor is shortened. User feedback application of permanent magnet couplings has achieved the desired goal of transformation.
