Issues with the two-in-one vacuum function
Thread Content
A few days ago, when we were trying to create a two-in-one setup, why couldn’t we achieve the desired vacuum level? It was in a cold state; later, in order to start the machine, the shaft seal was installed despite the vacuum level not being up to standard. What impact does this have on the equipment?
I don’t understand; is the order of injecting vacuum and injecting shaft seal reversed?
When starting the machine in a cold state and attempting to create a vacuum without using shaft seals, it will be very difficult to achieve the required vacuum level, as air and other gases will leak into the turbine as the vacuum decreases. As for the impact on the unit, it depends on the type of turbine – whether it is a condensing type or a back-pressure type. In general, this situation hinders the condensation of steam, leading to the accumulation of liquid inside the turbine chamber, which has serious negative effects
The order might be reversed; I think it would be best for the original poster to check the sequence of vacuuming! We usually install the shaft seal first and then evacuate the space! !
