Title: Foreign matter adhesion preventing method and device for impeller
Inventor: MURATA KEISUKE
IPC: F01D21/10
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To continuously operate for a long time a compressor used for a process in which powder and so on is entrapped, by supplying buffer gas to the back surface of the impeller main plate of a centrifugal compressor, and boosting up this buffer gas on the back surface of the impeller main plate so as to be made to be a forcible stream and to be led to flow into a working gas main stream. SOLUTION: When a compressor is operated in a manner that an opening/closing valve 7a is closed and a bypass piping 7 is closed, buffer gas introduced from a supply line 4 is led to flow as a white-decolored arrow and supplied to the back surface of an impeller main plate 1, and boosted up by the rotation of an auxiliary rotor blade 2 arranged on the back surface of the main plate 1. That is, a forcible buffer gas stream boosted more than supply pressure is generated between the main plate 1 and a casing 3, gets over an outflow part partitioned by a seal fin 6, and is led to flow out in a working gas main stream. Hereby, powder entrapped in the working gas main stream led to flow on the front side of an impeller, is prevented from being penetrated into the back surface side of the impeller by getting over the outflow part, therefore a seal part 9 and so on can be safely protected.

Abstract: PURPOSE:To facilitate the process of forming a bearing pattern by attaching a pad finished with the bearing pattern to a slider. CONSTITUTION:A pad 6 is formed through the process that a bearing pattern 7 for a static pressure gas bearing is finished beforehand on a small part. A static pressure gas bearing device is formed by attaching the pad 6 to a main body.

A clearance adjustment can also be performed by only grinding the attaching surface of the pad 6. Further, since the measurement of rigidity can be used on the other hand, uniformity of an amount off flotation can be achieved by giving a difference in the rigidity such as employing a high rigidity pad to the heavy load portion, in consideration with the dispersion of a load. The pad can be used in compliance with suitable usage there of by standardizing the pad.
