Expander gap pressure
Thread Content
What does expander gap pressure mean? What does it say about the working status of the machine?
First of all, it is one of the very important parameters of the expander. When the expander is operated, the sealing gas is added first and then the lubricating oil. The so-called gap pressure is the leakage air pressure behind the nozzle, because there is a concept of over-coverage between the nozzle and the impeller. The gap pressure has its effect.: Can balance part of the axial force! The key to the stable operation of the expander is to adjust the inlet pressure of the sealing gas according to the gap pressure, so that the pressure of the sealing gas is greater than the oil pressure and thus greater than the gap pressure. It is difficult to summarize in just a few words. Let’s have a chance to talk about it in detail! ! !
