Sealing under complex slag-gas-liquid conditions
Thread Content
There is a horizontal reaction vessel; the shaft oscillates by up to 0.5 millimeters. The reaction temperature is 105°C, and the pressure is 0.01 MPa. Inside the vessel, there is water and water vapor, as well as a highly toxic, flammable, and explosive gas, and a powder that causes severe wear (which covers the shaft). Initially, 5 layers of graphite packing were used for sealing, but after several replacements of the packing, the shaft became severely worn after 2 months, resulting in serious leaks, and repair was necessary. I would like to ask the experts here: is there any better way to handle this?
Why isn’t anyone responding? Is there nothing that can be done? Giving suggestions is also fine.
This issue can be addressed by using double-end mechanical seals; one can turn to Dandong Klon Sealing Parts Co., Ltd. or seek assistance from the manufacturers of slurry pumps, such as Jiangsu Jingjiang Jinlin Machinery Co., Ltd
I’ve thought about it; the quotation is in the tens of thousands per set, and one piece of equipment requires 4 sets, so the cost is unaffordable
