Abstract

PURPOSE:To aim at improving the lasting quality of a structural body in time of operation as a hydraulic machinery and equipment using a water system fluid and a drainage pump, by forming a vane part with a furnace-sintered ceramic body excellent in both of corrosion resistance and wearproof, and also forming a cam ring with a reaction-sintered ceramic body. CONSTITUTION:A vane 3 consists of a furnace-sintered body or a hot press sintered body being large in specific gravity and strength, comprising zirconium oxide (specific gravity 6 and strength 6kg/mm.<2>, silicon nitride, etc., by way of example. This ceramic body is sintered at a temperature of about 1,500-1,800 deg.C in a nitrogen ambience after a sintering assistant is added to ceramic powder and molded into shape. Likewise, a cam ring 4 is made up of a reaction-sintered ceramic body, which is easy for molding, especially reaction-sintered silicon carbide or the like is suitable for it in material, for example, being produced with a metal Si heated at a temperature of 1,300-1,500 deg.C in a nitrogen ambience or carbon. With this, even when it is used for hydraulic machinery and equipment using a water system fluid, it is excellent in durability and also when used for a drainage pump, there is no problem on corrosion, and use for long hours can be attained.
