What are the startup procedures for various types of units during vacuum extraction under reduced pressure?
Thread Content
There is a turbocharger, a primary steam ejector, a secondary steam ejector, as well as a set of water ring vacuum pumps. What are the specific procedures?
Can only a first-stage vacuum pump and a water ring pump be used? Or should only a steam evacuator be used instead of a water ring pump?
First, start the secondary steam pump, then the primary one, and finally the booster. Once the vacuum level stabilizes, the secondary pump should be replaced by a water ring pump; it should work that way. It depends on your usual operating practices.
Could you be more detailed? I’ve never used it before.

I’d like to ask gently: why can’t the water ring pump be started, along with the first stage and the booster? Could you explain that?
I want to start the water ring pump first, and then the steam evacuator. I’m not sure if it will work
