Abstract

PURPOSE:To provide light weight aluminum alloy for main composition material of pump, and provide alumite process for all surface of casting and rotor for improving heat resistance and corrosion resistance. CONSTITUTION:Pump casing 2 and rotor 5 are made of respectively aluminum alloy. Further, the internal surface of pump casing and the external surface of rotor 5 are processed by alumite treatment. Then, while respective vane 9 is pressure sliding along the internal surface 2a of casing 2, the internal circumferential surface 2 thereof is processed with alumite. Further, since the lubricant fed into the casing 2 applied oil film on the sliding section, the friction may be fully suppressed, where heat resistance and corrosion resistance property may be improved remarkably by alumite process. Rotor 5 and end frame surface 1a, casing inner surface 2b may be applied similarly.
