静圧型空気軸受を有する流体圧縮機、静圧型空気軸受を有する圧縮機の制御システム、及び静圧型空気軸受を有する圧縮機の制御方法

Japanese Patent JP2009511803

A

The present invention relates to a fluid compressor having an aerostatic bearing, to a control system of a fluid compressor having an aerostatic bearing as well as to a method of controlling a compressor, wherein the aerostatic bearing is fed by a compressed fluid accumulator (5) which is charged during the operation of the compressor (100) and discharged at the respective start to prevent damage to the bearings. These objectives are achieved by means of a fluid compressor (100) comprising a pressurization chamber (C) and at least one fluid pressurization device (1, 2, 18), the pressurization chamber (C) and the pressurization device (1, 2, 18) being located in a housing (4), the pressurization chamber (C) having a non-pressurized inlet (10) and a pressurized outlet (20), the pressurization device (1, 2, 18) compressing the fluid collected by the non-pressurized inlet (10) and discharging it through the pressurized outlet (20), the pressurization device (1 , 2, 18) having at least one aerostatic bearing (3), the aerostatic bearing (3) comprising a floating pressurization region (33), the compressor comprising a compressed fluid accumulator (5) fluidically connectable to the pressurized outlet (20) and the floating pressurization region (33), the compressed fluid accumulator (5) being located inside the housing (4) of the compressor (100). A system for controlling a compressor (100) and the respective control method are further described.
