Changyi Petrochemical's electronic equipment maintenance personnel recently dismantled damaged frequency converters and took out various parts for tests. They assembled parts still intact and put them together as functional frequency converters. At the moment, more than 10 frequency converters were born this way, saving 100,000 yuan ($16,200) in maintenance costs.
The company has used many frequency converters since 2004 to regulate technological processes. Some parts of frequency converters were down over the years, and more than 20 frequency converters were out of service. The lack of maintenance personnel and related expensive costs became a persistent problem.
The successful frequency converter assembly also helped upgrade maintenance personnel's technical skills and create value for the company.
