Title: Runner of centrifugal compressor
Inventor: KUWABARA KENICHI
IPC: F04D29/46
Filed: 1989-09-18
Abstract: PURPOSE:To improve efficiency of a compressor in the range of small discharge volume in a runner composed of a core plate, a side plate and blades by arranging some extensible objects between respective blades. CONSTITUTION:When air flow into a runner 5 decreases owing to decrease of opening of inlet guide vanes 10 according to action of an inlet guide vane control device 11, a pressure regulating device 14 operates so as to raise the pressure in a chamber 13 higher than that inside the compressor according to the signal from the control device 11. Then, the pressure in the chamber 13 is transmitted to the extensible objects 21 via a piping 15, a shaft 7, a cover 17 and the runner 5. Because the objects 21 are extended by the pressure difference, space between blades of the runner 5 is narrowed by the objects 21. So, fluid does not flow into the space. On the contrary, space between blades blades where the extensible objects 21 are not arranged can afford to flow a large volume of fluid keeping flow angles at an entrance and exit of the runner under efficient conditions. Consequently, even if the compressor is operated in the range of small discharge volume, high efficiency at the design point can be gained.

Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To reduce cost and weight, eliminate the clouding, and make a mirror surface hardly damaged by providing a super-hydrophilic thin film coating layer on the surface of a stainless material subjected to hard chromium plating. SOLUTION: A base material 1 formed of stainless plate is made into a necessary form such as concave or convex surface, and the surface of the base material 1 is then subjected to hard chromium plating to form a hard chromium plating layer 2. The plating layer 2 surface is polished and mirror finished. A thin film formed of photocatalyst is baked on the polished surface to provide a mirror surface coated with a super-hydrophilic thin film 3. Thus, since the clouding of the surface is prevented by the coating of the super-hydrophilic thin film without requiring a heat reservoir or heat transfer mechanism, natural characteristics of stainless mirror of low cost, small thickness and light weight are never lost. Since the mirror surface is covered with the hard chromium plating layer, it is hardly damaged.
