Abstract
PURPOSE: To lower cost without impairing the function of a titled pump by using the specific Al2O3 which is changed of its structure and is molded and sintered by a rubber press method etc. for the cylinder and/or plunger tip of the pump.
CONSTITUTION: The high purity Al2O3 of ≤1.5% SiO2 content which permits molding and sintering by a relatively inexpensive rubber press or slip casting method or which consists in adding a sintering assistant such as MgO or Y2O3, is used for a cylinder 1 and a plunger tip 15. A cylinder ring 20 etc. made of material such as graphite having corrosion resistant against molten metal of Al or Al alloy and supeiror thermal impact resistance is insertionally fitted to this so that these parts having inferior thermal resistance do not receive thermal impact. At the pouring of molten metal 13 to a pump body 11, first it is poured up to the ring 20 and after the temperature at which the cylinder 1 and tip 15 do not receive thermal impact is reached, the additional molten metal is poured.
