Control logic diagram for internal compression process liquid oxygen pump
Thread Content
This post was last edited by wlmwq on 2017-8-18 08:41. Does anyone have the PID diagram for the liquid oxygen pump in internal compression mode, along with the corresponding interlock logic diagram, for reference? The liquid oxygen pump is equipped with an inverter; equipment driven by inverters generally have poor resistance to power fluctuations. Are there any effective solutions for this issue? Are there any mature anti-interference devices available on the market?
The interlock logic can be equipped with a function for self-resetting after power fluctuations, and the frequency converter can also have its settings optimized. Anti-surge equipment is essentially similar to a very large buffer power supply; there is a company in Nanjing that specializes in DC banks, and the poster might want to look into that.
Indeed, there are quite a few reports on practical anti-interference technologies for DC-banks these days~~ which involve adding an uninterruptible DC power supply~~
