To those outside the industry, what is the level of domestic production for low-temperature expanders?
Thread Content
For industry research, I would like to ask everyone about the current level of low-temperature expanders in China – have they been fully domestically produced? I see that Cryostar has magnetically suspended expanders – why isn’t such technology developed in China? Thanks, experts :)
Domestic air separation plants are trending toward using foreign expanders; how can you recoup the development costs you have invested?
Domestic expanders are fairly decent; for example, those produced by Hangyang perform well. But if we look more closely, they certainly can’t be compared to imported equipment.
If the magnetic bearing technology is provided by someone else, how much money and how much time will it take for the expander manufacturer to develop new magnetic levitation expanders, for example those with a capacity of 3 or 4 MW?
The high cost of magnetic bearings is mainly due to control issues; if you want magnetic bearings, you’ll have to pay at least an additional 1M
The expander of Chuan Kong is pretty good, right? I was chatting with someone from the industry today; a project that used Sichuan Aeronautic’s high-pressure expanders ended up destroying at least 6 shafts, haha~~
