1. Equipment damage
Motor overheating: Overload will cause the motor current to increase, generate too much heat, accelerate the aging of the internal parts of the motor, and even burn the motor coil.
Bearing damage: Overload will cause the force on the motor rotor to exceed the bearing range of the bearing, causing bearing damage and increasing maintenance costs.
Mechanical structure deformation: If the welding positioner is overloaded for a long time, it may cause the mechanical structure to deform, affecting the accuracy and stability of the equipment.
2. System performance degradation
Reduced efficiency: Overload operation will significantly reduce the operating efficiency of the equipment and increase energy consumption.
Insufficient output power: Overload may cause the output power of the equipment to decrease and fail to meet the requirements of the welding process.
3. Safety hazards
Fire risk: Overload operation may cause fire, especially when the motor insulation material burns or the equipment overheats.
Electric shock risk: Overload may cause equipment insulation damage, increasing the risk of electric shock accidents.
4. Production interruption
Equipment shutdown: Overload may cause equipment failure or the automatic protection device to start, causing the equipment to stop working and affecting production efficiency.
Increased maintenance costs: Overloaded and damaged equipment requires maintenance or replacement of parts, increasing production costs.
5. Impact on welding quality
Welding defects: Overload may cause unstable welding current, affect welding quality, and increase the probability of welding defects (such as undercut, lack of fusion, etc.).
Preventive measures
In order to avoid the risks brought by overload, the following measures should be taken:
Reasonable selection of equipment: Select a welding positioner with appropriate load capacity according to actual needs to avoid overload operation.
Install protective devices: The equipment should be equipped with overload protection devices, such as overload protection switches, overheating protection devices, etc.
Regular maintenance: Regularly check the electrical and mechanical components of the equipment to detect and repair potential problems in a timely manner.
Operating specifications: Strictly operate in accordance with the operating procedures of the equipment to avoid long-term overload operation.
