    • PURPOSE: A blade of a gas turbine compressor and a manufacturing method thereof are provided to manufacture a plurality of the blades rapidly and easily by processing the blades simultaneously as a dovetail protrusion is arranged and fixed in a circumferential direction, and each contact surface is turning-operated simultaneously. CONSTITUTION: A blade of a gas turbine compressor includes a blade body (110) and a dovetail protrusion (115). The blade body includes a blade unit (112). The blade unit is arranged to be inclined in an axial direction. The dovetail protrusion includes a contact surface having predetermined radius curvature under the blade body. The radius curvature of the contact surface and the radius curvature of a dove tail slot are effectively the same.

    • PURPOSE: A bearing oil supply device of a gas turbine is provided to reduce damage to a bearing by evenly and uniformly supplying oil over the front and rear sides of the bearing using a second oil flowing path part. CONSTITUTION: A bearing oil supply device of a gas turbine comprises a jet hole(13) and a second oil flowing path part(15). The jet hole ejects oil to a hollow part through an opening part from an oil storeroom. The jet hole is located on a partition wall(12) of the oil storeroom. The second oil flowing path part guides oil of the hollowing part to a bearing(20) using the centrifugal force of a rotor(30). The second oil flowing path is formed on the rotor. The second oil flowing path part comprises a second oil path and a guide member(35). The guide member is formed on a rotator.
    • 目的:提供一种燃气轮机的轴承供油装置,通过使用第二油流路部分均匀均匀地在轴承的前后两侧供油,从而减少对轴承的损坏。 构成:燃气轮机的轴承油供给装置包括喷射孔(13)和第二油流路部(15)。 喷射孔通过油藏室的开口部分将油喷射到中空部分。 喷射孔位于储油室的隔壁(12)上。 第二油流路部分使用转子(30)的离心力将中空部分的油导向轴承(20)。 第二油流路形成在转子上。 第二油流路部分包括第二油路和引导构件(35)。 引导构件形成在旋转体上。

    • The present invention relates to an apparatus and a method for fixing a blade ring assembly for a compressor. The apparatus for fixing the blade ring assembly comprises: a casing forming an appearance of a compressor; and the blade ring assembly which is installed in a rear end of the casing, and has a plurality of vanes formed along an inner circumferential surface in a multi-stage manner. The casing includes a fixing part fixing the blade ring assembly. The blade ring assembly has a split structure with an upper ring and a lower ring manufactured in the same shape by a molding method using one mold. Although vibration or shock is generated in a radial direction of a casing, an axial direction, and vertical and horizontal directions, the apparatus and the method for fixing the blade ring assembly for the compressor can prevent the blade ring assembly from moving by stably fixing the blade ring assembly.
    • 本发明涉及一种用于固定压缩机的叶片环组件的装置和方法。 用于固定叶片环组件的装置包括:形成压缩机外观的壳体; 以及叶片环组件,其安装在壳体的后端,并且具有以多级方式沿着内周面形成的多个叶片。 壳体包括固定刀片环组件的固定部件。 叶片环组件具有通过使用一个模具的模制方法以相同形状制造的上环和下环的分割结构。 虽然在壳体的径向,轴向和垂直和水平方向上产生振动或冲击,但是用于固定压缩机的叶片环组件的装置和方法可以通过稳定地固定 叶片环组件。
