After the compressor stops, the vacuum level remains high – should the vapor seal pressure be maintained?
Thread Content
The speed of the compressor is reduced to 0; if the vacuum level is high, it is necessary to maintain a continuous pressure at the steam seal. Why is this? Are you worried about damaging the steam seal?
On the one hand, the aluminum steam seal may deform under suction; on the other hand, there is a concern that media might flow back into the purified air
The question is too technical; it would be better if it could be more detailed. There are many types of compressors. The applicable processes vary. A flowchart should be included to make things clearer when looking at it, for reference.
The question is not clear. First, think about what the function of the gas seal is – it is to maintain a vacuum. And what is the purpose of maintaining a vacuum? It is to enable the compressor to start operating. So, are you planning to stop the machine temporarily and start it up soon? If it is stopped for a long time, the vacuum level needs to be relieved promptly. When the gas seal is opened, the shaft must be rotated continuously; rotating it at low speed is not good for the dry gas seal, and the duration should not be too long. In my case, the compressor should not be stopped for more than 6 hours
