Nitrogen sealing system
Thread Content
Who has extensive experience with nitrogen sealing systems? I would appreciate some guidance. The problem I’m facing on site is that the nitrogen supply valve allows only a small amount of air to flow in, resulting in negative pressure
It would be best if you could send a schematic diagram for your question, or clearly explain the relevant process and in what way nitrogen sealing serves a purpose. Nitrogen sealing is used for static sealing, dynamic sealing, and other special applications. Please specify, to facilitate discussion.
The nitrogen sealing system uses segmented control, which keeps the pressure stable
The valve pressure isn’t properly adjusted; adjust the spring stroke again
It seems too small once it’s put into use; this issue only appeared recently. It’s hard to determine whether it’s a problem with the selection – the nitrogen seal valve being too small – or whether the passage has become blocked after use.
The situation on site is that the nitrogen inlet rate cannot keep up with the discharge rate; negative pressure occurs during discharging. Currently, the discharge flow rate is 32 tons per hour, while the nitrogen inlet flow rate is 38 cubic meters per hour.
Are the flow rates of the liquid and the gas corresponding to each other? If anyone knows the answer, could they please contact me via WeChat?
