- 摘要:
- 导叶为泵类产品必不可少的配件,流道窄,分层多。为保证产品质量,采用整体精密铸造工艺,模具分3副模具,3部分进行组合为一件蜡胚产品。制壳时采用特制灌浆工艺,保证导叶流道浇注后不夹铁,方便后道工序清理流道。并通过ProCAST模拟软件,模拟浇注工艺设计的可靠性,从而确保了产品质量。
Guide vane is an essential accessory for pump products.The flow channel is narrow and multi-layered.In order to ensure the product quality,the overall investment casting process is adopted.The mold is divided into 3 sets of molds,and the 3 parts are combined into a wax embryo product.Special grouting process is adopted in shell making to ensure that the guide vane runner will not be filled with iron after pouring,and it is convenient to clean the runner in the following process.And the reliability of pouring process design is simulated by Procast simulation software,so as to ensure the quality of products.
