Filed: 1994-11-25
Abstract: PURPOSE: To improve the quality of the surface layer, the electric conductivity, the surface hardness and the durability by realizing the fine metal matrix of a surface part of an electrode or nozzle tip. CONSTITUTION: The shot peening treatment is achieved by ejecting shots of 40-300μm in grain size as hard as an electrode or nozzle tip against the surface of the electrode or nozzle tip made of non-ferrous metal at the ejection speed of >=100m/sec. The temperature in the vicinity of the surface of the electrode or nozzle tip rises to or above the recrystallization temperature. The metal matrix of the surface part of the electrode or nozzle tip becomes fine in the process of recrystallization, the electric resistance is extremely reduced, and the electric conductivity is increased. The surface hardness is increased by the work hardening due to the shot peening treatment, and the fine crystalline grains of the metal surface due to the repeated cooling from the recrystallization temperature to the solution heat treatment temperature and to the normal temperature.

Title: Shaft sealing device of turbo machine
Inventor: ISHII EIJI
IPC: F16J15/447
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent shaft vibration by uniformizing the pressure in the circumferential direction of an annular gap by providing a circumferential communicating space on the inside in the radial direction of a rotating part corresponding to the annular space, and communicating the space with the annular gap by a through hole bored in the rotating part. SOLUTION: A fluid enters from the shaft sealing inlet pressure P1 side of an annular gap 15 to go out to the shaft sealing outlet pressure P2 side. A circumferential communicating space 19 is provided inside a sleeve 14 and allowed to communicate with the annular gap 15 by a through hole 18 in the surface of the sleeve 14. As the space 19 is rotated with the rotating shaft, a circumferential current is generated in the interior. The unstable vibration of the shaft is generated because the width of the annular space 15 changes in the circumferential direction due to whirling of the rotating shaft 12 so that the circumferential pressure distribution becomes non-uniform.  A fluid is enabled to go in and out between the annular space 15 and the space 19 through the through hole 18 efficiently by utilizing the circumferential current in the space 19, whereby the circumferential pressure distribution can be made uniform. The unstable vibration of the rotating shaft can be prevented.
