What impact does maintenance technology have on chemical plant maintenance and even the operation of chemical equipment?

Thread Content

I changed jobs several times before, but all of them were related to the maintenance and management of chemical processing equipment. I worked as a fitter, an equipment engineer, and as an assistant equipment manager. As a fitter, I strived to improve my technical skills and wanted to understand every aspect of the equipment. After working for 7 or 8 years, I realized that although I was good at maintenance techniques, there weren’t many maintenance tasks available in factories. Eventually, tired of this situation and with no opportunities for further development, I switched to becoming an equipment engineer. I then understood that the quality of maintenance techniques directly affects a company’s operating costs. Once, during a bearing replacement, the set screws weren’t secured properly; as a result, the inner ring of the bearing damaged the shaft shortly after the machine was started up. During the disassembly process, the impeller was also damaged. Since the fan was imported equipment, replacing the bearing required several spare parts – two additional bearings, one shaft, and one impeller. When later serving as the deputy director of equipment management, one must consider not only the quality of equipment maintenance but also the operating conditions of the equipment. For those pieces of equipment that have unresolved safety issues, measures must be taken to prevent accidents; at such times, it is necessary to take into account not only maintenance techniques but also various safety factors. Among all the companies I have worked for, I was interviewed by a chemical company where a certain piece of equipment kept causing problems, which led to unstable operation of the plant; it had to be shut down every 5 days or so, and as a result the company’s operations were in a very difficult situation. If all chemical companies paid attention to maintenance technologies, would that mean the entire chemical industry could also improve?
