Research on the Clearance Seal in Stirling Refrigerator

Abstract:

The regenerator of Stirling refrigerator is normally installed a contact sliding sealing ring, but if the sliding sealing ring working hour is overlong, it would cause wear heavily, and reduce the service life. This paper focus on resolving this problem: use a clearance seal device, which without leakage under the high pressure test, instead of the sliding sealing device. Meanwhile, use the clearance seal device would eliminate contact wear which would cause the leakage losses. Therefore it is fairly important to establish a theoretical model to imitate leakage process in the clearance seal device, analyze the factors which influence clearance seal, and find a solution to improve clearance seal in Stirling refrigerator.
