The adjustment of electromagnetic brakes mainly includes the magnetic yoke, armature, coil, spring, and power-off release brake:
1. Adjusting the clearance of the electromagnetic brake is important because the friction plates of the electromagnetic brake will wear out after long-term operation, leading to an increase in clearance
2. In severe cases, it can affect the abnormal engagement of the armature, the brake cannot be released normally, the engagement voltage of the armature coil increases, the suction and braking forces decrease, and even burn out electrical components such as friction plates (check transaction price | reference | preferential policies) If the clearance is not adjusted, it is likely to affect the braking effect The adjustment of electromagnetic brakes can be mainly divided into the following three types: the adjustment of the iron core suction clearance of electromagnetic brakes, the adjustment of the brake shoe braking clearance, and the adjustment of braking torqueRequirement:
1. The elevator hall should be placed on the middle floor and the main power should be disconnected. After confirming safety, adjustments and production can be made.
2. When using a brake wrench to release the brake pads, continuous and even force should be applied to prevent slipping When replacing the brake band, the contact surface between the brake band and the brake wheel should be kept clean and free of oil stains 4. After the adjustment work is completed, each part of the brake should be carefully inspected, and after confirming that there are no problems, the power test should be conducted The adjustment of electromagnetic brakes plays an important role in the installation and use of electromagnetic brakes Electromagnetic brake (electromagnetic brake) is mainly matched with series motors. Widely used in metallurgy, construction, chemical industry, food, machine tools, stages, elevators, ships, packaging and other machinery, as well as in situations such as braking during power outages (safety measures)
