Novel light anti-eccentric-wear integral piston

The utility model relates to a novel light anti-eccentric-wear integral piston, and belongs to the technical field of large slurry pumps. Comprising a piston core and elastomers. The piston core comprises a top part, a head part and a lip part; a protrusion is arranged on the lower edge of the head, and a groove matched with the protrusion is correspondingly formed in the elastic body. The piston core is made of aviation aluminum; and the piston core and the elastic body are integrally vulcanized and formed. The piston core is made of aviation aluminum, so that the problems of eccentric wear, cylinder sleeve strain, high transportation cost and difficulty in assembly caused by heavy weight of a steel piston core of an existing large-specification integral piston are solved, production and processing are facilitated, and convenience is provided for batch production of the integral piston. 本实用新型涉及一种新型轻质防偏磨整体式活塞，属于大型泥浆泵技术领域。包括活塞芯和弹性体；所述活塞芯包括顶部、头部、唇部；所述头部下边缘设置有凸起，所述弹性体上对应设置与凸起相匹配的凹槽；所述活塞芯的材质为航空铝；所述活塞芯和弹性体一体硫化成型。本
