Temperature control of the free end of the high-speed shaft in the gearbox of the backup main fan
Thread Content
Our factory has newly installed an 800,000-ton heavy catalyst reactor, which has been in operation for over a month as of 07.12.24. The exhaust fan has not yet been put into use; instead, the air supply is provided by a backup main fan. The temperature at the free end of the high-speed shaft of this backup main fan has reached 99 degrees, just 5 degrees below the warning threshold. Neither adjusting the lubricant temperature nor the lubricant pressure manages to lower this temperature. If it’s an internal issue, such as shaft friction, then why doesn’t the temperature keep rising continuously? Moreover, it’s not possible to shut down the equipment for inspection right now, as it has just started operating. I kindly ask everyone for their help; I would like to express my gratitude here.
