一.概述耐高压(107)调节器主要用于重型机械上,其中属关键铸件的调节器壳体,曾在国内几个工厂试铸未成功。我厂用均衡凝固理论指导工艺设计铸件各项指标均达到设计要求,现已投入批量生产。二.铸件的技术要求107调节器壳体工作压力为4.1×10~7～4.7×10~7Pa 铸件内腔及两条油道要求耐4.7×10~7pa 油压试验,不允许渗漏。铸件上下两端面要求研磨,表面粗糙度要求达
I. Overview High pressure (107) regulator is mainly used on heavy machinery, which is a key casting regulator shell, had several plants in the country trial was unsuccessful. I plant with the theory of equilibrium solidification design process casting all indicators have reached the design requirements, is now put into mass production. Casting technical requirements 107 regulator housing working pressure of 4.1 × 10 ~ 7 ~ 4.7 × 10 ~ 7Pa casting cavity and two oil passages required resistance to 4.7 × 10 ~ 7pa hydraulic test, does not allow leakage. Casting the upper and lower ends require grinding, surface roughness requirements of up to
