Zusammenfassung:The invention belongs to the technical field of non-variable displacement pumps, and relates to a production method of a collector tube for a pump. The machining technology of the liquid collecting pipe comprises the following steps that S1, an inner cavity mold core of the liquid collecting pipe is manufactured; s2, dipping the inner cavity mold core with ceramic slurry to obtain the inner cavity mold core wrapped with the ceramic slurry, and then drying and sintering the inner cavity mold core to obtain an inner cavity shell; s3, manufacturing a shape mold and a metal solution of the collector tube; s4, the inner cavity shell is placed in an outer mold, and the molten metal is poured into the outer mold for casting; s5, after casting is completed, a product in the shape mold is cooled; and S6, after the metal solution is completely cooled and solidified, opening the mold to obtain the collector tube. According to the collector tube produced through the production method of the collector tube, due to the fac
