2011
The utility model discloses a primary blade of a gas compressor with a hub diameter of [phi] 940. The utility model discloses a blade of a gas compressor, and specifically relates to the primary blade of the gas compressor with the hub diameter of [phi] 940. The utility model aims at solving the problems that the molded surface of the primary blade of a conventional gas compressor with the hub diameter of [phi] 940 is not smooth, the quality is not stable, the service life is short, and the safe running of the gas compressor is influenced. The primary blade consists of a blade working part and a blade root; the geometric data of cross sections of the blade working part from a root part to a top part are that the cross sections from a cross section number A-A to a cross section number J-J have heights of 8.19-180.94 mm, axial widths of 86.388-60.947 mm, chord lengths of 90.744-90.812 mm, gas inlet angles of 46.779-33.278 degrees, mounting angles of 70.931-41.610 degrees, and maximum molded line thicknesses of 10.600-4.847 mm; and the total height of the blade working part is 180.28 cm. The primary blade is used on the gas compressor with the hub diameter of [phi] 940.
