摘要： PROBLEM TO BE SOLVED: To provide a method for detecting penetration defects of a line which is capable of detecting whether or not there are penetration defects of the line as well as specifying the locations of the defects in a short time with high accuracy, and an apparatus therefor. SOLUTION: A pair of elastic rubber films 12a and 12b expanding toward the inner peripheral surface of the line A on being exerted with pressure fluid are inserted into the line A while in predetermined spaced relation along the direction of the pipe axis and are expanded by the fluid pressure until making contact with the inner peripheral surface of the line A to form sealing walls αand βdividing the interior of the line A along the direction of the pipe axis; the sealed space 33 of the line A divided by the sealing walls α and β is pressurized, after which a pressure sensor 34 detects whether or not there are penetration defects of the line depending on the rate of pressure drop in the sealed space 33. Thus, detection of penetration defects of the line A leading to leakage can be carried out not for the entire line but for each part of the line A, so that only a sealed space of small volume is needed.

摘要： A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leafs are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft. When the turbine is not operated, the top ends of the leaves contact the rotation shaft again due to the elastic restoring force of the leaves.
