Ultra slim robot created by Mitsubishi Electric, designed for the inspection of generators
Mitsubishi Electric announced the creation of a robot with a thickness of only 19.9 mm, is designed for inspection of power plant generators. The small thickness allows the robot to pass into the gap between the stator and the rotor, eliminating the need for removing the latter. Thus, the robot significantly reduces the time and cost of validation by allowing you to increase the reliability and uptime of generators.
According to Mitsubishi Electric, a routine check of the generator, performed every four years, requires approximately 34 days. In many ways, this period is explained by the need to remove the rotor. As stated, assuming the use of work time of inspection was reduced to six days. In addition, due to the high accuracy inspection is possible to increase the interval between inspections and stocked fewer spare parts.
The new robot is able to carefully check the condition of the generator, including the quality of the insulation. The manufacturer notes that the mechanism for moving the robot has a low vibration level, due to its increased accuracy.
It remains to add that the thickness of the conventional robot inspectors — about 30 mm, which does not allow them to pass into the gap between the stator and the rotor approximately 30% of the generators by Mitsubishi Electric.
