As the title says. I truly hope that all marine enthusiasts will give their enthusiastic support. I can also help analyze the actual condition of the foreign-made machines you are using based on DCS. If it’s inconvenient, you can send an email to tanxjzm@126.com. Thank you

Have you ever encountered expanders that need to pass through a resonance zone? ~~Thank you!

I had seen it in foreign technical documents before; it has become less common in recent years, as most designs now feature rigid shafts

We have a Cryostar here that needs to go through resonance operation; it gives an alarm after 1 minute and triggers interlock after 3 minutes. When I first started working with it, the start-up process was like being in a battle!! But things are much better now~~

Set the initial opening of the nozzle to a higher value, and adjust the reflux setting to a slightly lower level in order to quickly pass through the resonance zone. With enough experience from operating the machine, one can figure out the optimal settings *Habit helps a lot, haha

The ACD I’m using skips directly after 3 minutes, as it needs to pass through two resonance zones

During startup, was there an interlock shutdown due to excessively high shaft temperature? Hehe, how do you usually proceed? Could you share roughly~~ Thanks~~

I’m just worried that the shaft temperature will be too high~~ Hehe

It should be noted that the nozzle opening degree is different during cold start and hot start; the opening degree of the nozzle during hot start is not as large as that during cold start, due to the difference in the internal energy of the air.
