Abstract
PURPOSE: To provide a pump whose wear is small and which excels in sealing-up and working properties, by composing the material of each of a rotor, a crankshaft and a bearing of prescribed quantities as to weight percentage.
CONSTITUTION: A rotor 1 is made of an alloyed cast iron which comprises 3.00W 3.60wt% of TC, 1.50W2.50wt% of Si, 0.50W1.00wt% of Mn, 0.30wt% or less of P, 0.50W1.00wt% of Cr, 0.15W0.25wt% of Ni, 0W0.25wt% of Mo, 0.02W0.06wt% of B and the rest of iron and which has a martensite structure in which special steadite is dispersed by quenching. A crankshaft 4 is made of a cast iron which contains 0.02W0.06wt% of B and which contains 5.0W10.0 surface % of special steadiate in the pearlite matrix. A bearing 5 is made of a boron-containing cast iron which contains 0.08wt% or less of B and which contains 3.0W8.0 surface % of special steadite in the pearlite matrix. These materials are combined with one another to greatly improve the wear and seizure-resisting properties.
