Leak in the expander seal air

2009-03-04View Original

Thread Content

Recently, the heat-sealing gas at the expansion end of the Atlas expansion turbocharger in operation has been leaking from the low-pressure port of the pressure relief valve. The original pressure difference of 80 KPa is now zero. Several attempts to stop the leak were unsuccessful, and no pressure difference remains; the cold air has caused frost to form on the outer bolts. The company does not want to shut down the unit for repairs, while the workshop is concerned about potential damage to the equipment. What should be done? I seek advice from experts For clarification, there are two streams of heat-sealing gas at a pressure of 4.8 MPa, with a pressure difference of 80 KPa between them; the lower pressure is present at the cold end
