There has been a problem with the steam turbine of our plant's unit. This time it was disassembled as shown below. Can someone who is engaged in the steam turbine maintenance industry tell me how long it will take to repair it?
Looking at the picture, it needs to be returned to the factory for repairs and blade replacement. It is estimated that it will take about 2 months as soon as possible.
I had already sent it to the Hangzhou manufacturer the day before yesterday. Why does it take so long to replace the blades?
Hangzhou Gas does not specialize in your steam turbine, there are n more than one, so queue up slowly.
If the blades are not in stock, they will still need to be made, and it will probably take a while for the forgings to be processed. How long has this turbine been used? How could this happen? Both the regulating stage and the final stage are damaged. Is it running overloaded for a long time?
If there are impeller spare parts, they will be ready in one week. If not, you have to see the manufacturer.
Send it directly to the manufacturer. After testing first, the two parties will jointly agree on a solution based on the test data. The repair should be completed in 2 to 3 weeks, and the replacement will take about half a year! (If the factory goes with the chief engineer or vice president who has a good relationship with the manufacturer's senior management, the problem will be easier to solve, and you can jump in line directly, you know)
The damaged blades are removed, and the spare parts or newly made blades are installed, all by hand. After completion, you still have to do surveying and dynamic balancing, which will take time because there are many people queuing in front of you.’

The same applies to our steam turbines from Hangzhou Zhongneng. There are many users across the country. Just wait and see.
For 600,000 tons of methanol, the synthetic compressor units should all be customized, and spare parts are probably not available. We started driving it at the end of 2013. In August this year, the vibration of the intake end shaft became larger and fluctuated by 50 microns. I never dared to adjust the speed. In early December, when the gasification inverter burner was loaded, it couldn't hold on anymore and the interlock jumped.
