At the heart of Itaipu: Electromechanic innovation
Font Size

An idea came to mind for welder Adilton Victoriano, 8 years at Itaipu, and boilermaker Jefferson Gilberto, 3 years, when they received a project for another job in the Electromechanic Workshop. “Why not do things differently?” they thought. 



The idea yielded more economy for Itaipu and shows that, even when the generating unit is programmed to stop, there is room for innovation.


That is what happened in the modification of a section of hydraulic piping on elevation 98 (check in the coming material of the series “At the heart of Itaipu"), an operation carried out during U07 maintenance. The Maintenance Team drafted the design, took the project to the Electromechanic Workshop and mechanical engineer José Augusto Azevedo, responsible for the Workshop, forwarded it to for production by the technicians.  Adilton and Jefferson went into action.


“When we received the project, we saw that the piping could be made with less curves”, said Jefferson. The idea gained the endorsement of José Augusto and, after approval by the Engineering Department, the changes were made to the project.


“We made great savings in both material and service time”, said José Augusto proudly.  The innovation will be carried out in the quadrennial maintenance of the 20 generator units. In numbers, the total saving equals 20 piping curves, the 40 welds necessary for these curves and 60 braces. And, of course, the economy in work for doing all of this.


Workshop strength


Technicians from the Electromechanic Workshop show that they don’t play around when work gets tough. You well remember the gasket changes in the Servomechanism arms:  the whole mechanic team was focused on the machine when, oops!, one of the hydraulic brakes jammed.


Fiddling here and there didn’t help at all. “We realized that if we continued applying pressure we could damage the part”, explained Gabriel Caballero (SMMU.DT), responsible for mechanics area for the turbine, speed regulator and water intake. The solution was to create a tool specifically for removing this part.


And that is a job for the Workshop. It was Caballero that made the design - two rings that fit onto the part. The Workshop technicians did the welding and machining for the tool, the mechanic team applied it to the part and, vualá, they managed to free it.
