Commissioning of the turbine dry gas seal
Thread Content
Why must the drying and sealing process begin 10 minutes before the lubrication system is put into operation, and end 10 minutes after the lubrication system is shut down?
One more question: when sealing with a dry head, what is the purpose of using the first-level seal first and then the second-level seal?
To put a dry gas seal into operation, it is necessary to first supply the isolation gas for the dry gas seal, and then add the lubricating oil, in order to prevent the lubricating oil from entering the dry gas seal. By introducing the secondary sealing gas first and then the primary sealing gas, back pressure can be generated on the primary seal, thereby damaging it.
What type of turbine does it use for dry gas sealing? ? ? ?
It should be a compressor driven by a turbine
All turbines are equipped with dry gas seals, which is quite advanced
It is generally used to prevent lubricating oil from leaking into the engine compartment~~~
What was said upstairs is correct: first inject isolation gas, and then apply dry gas sealing. Prevent lubricating oil from leaking into the dry gas seal and damaging it.
Prevent the sealing system from being contaminated by lubricating oil
