摘　　要：采用湿型、对开垂直分型工艺、挤压造型生产轴流泵体 ,浇注系统按等压等流量进行设计。型芯用覆膜砂壳芯 ,为解决变形 ,砂芯内腔放灰铁压块。按此工艺生产 ,成品率达 90The axial flow pump body casting is produced by green sand mold, split vertical parting technique, squeezing molding, and resin sand core embodied gray cast iron weight, and the pouring system is designed according to isobaric and equi-flux technique. Through production practice, the yield of pump body casting reaches 90% or above.
