Disassembly process of keyless coupling
Thread Content
In the process of overhauling the ammonia compressor, the ammonia compressor and the steam turbine are connected through a keyless coupling. We encountered great obstacles during the disassembly process. After careful study later, we found that the disassembly and assembly principle is actually quite simple. Here are the schematic diagrams and actual pictures I compiled.
The disassembly tools are provided by the manufacturer, right?
The principle of this device is very simple, but the technical content of the hydraulic disassembly and assembly process is still very high, especially the maintenance process. If you look at the bearing bush and coupling, it should be a sinking drum compressor or a Schenck coupling. For example, you need to measure the depth of the shaft head before disassembly, and control it not to pull lint during the pressing process. When reassembly, use the designed depth of the shaft head as the standard or the amount of advancement, etc.
Yes, I was a little confused the first time I met you, but it’s not that difficult if you get it right.
The compressor facing the sinking drum was inspected for the first time. The equipment was disassembled and the coupling was encountered.* * Annoying, almost no one in the factory knows the matching disassembly tools!
My unit is like this too, and it hasn’t been demolished yet.
Must be suppressed to 160mpa---220mpa
Thanks for sharing, it should be a special tool.
This is the same as the principle of SKF bearing tooling. The shaft is machined with holes and channels, and then pressurized by a hydraulic pump. Many imported equipment bearings are installed like this. Once you know how to use it, it is actually very convenient and does not damage the equipment or accessories.
