Regarding temporary sealing during the testing of hydrogen circulation pumps
Thread Content
There’s something I don’t understand; I’d like to ask the experts here! During the individual testing of the circulator in the hydrogenation unit, the dry gas seal was not put into use; instead, a temporary seal for the dry gas seal was placed there. I have never seen such a temporary seal before, and I am not aware of its structure or working principle. Additionally, I would like to ask what precautions should be taken during the individual testing of the circulator, and what considerations should be given when using temporary seals. I hope experts can provide some guidance, and it would be great if pictures could be included! Thank you!
That thing is the test-running seal provided by the manufacturer; I think it’s made of ZL104 material and is a labyrinth seal. By the way, are your machines from Shengli Blower?
We are SHENGU’s compressors! The dry gas seal is from John Crane!
It’s a comb-tooth seal, used during no-load tests of the centrifuge to prevent lubricant from entering the centrifuge
