柴油泵壳体CRF_1-110-01系公司新开发民品柴油泵(大马力)主体零件,铸件质量关系着油泵性能和开发前景,原采用单边缝隙浇注成品率低,报废率高达85％,对铸件浇注系统工艺改进后合格率高达97％。1 铸件工艺性分析及技术要求 柴油泵壳体。铸件材料ZL-101,铸件重量12.7kg,用0.3MPa空气压力在煤油中检查内腔和孔的密封性,时间保持3min。根据铸件结构特点及技术要求,为保证铸件气密性要求,采用金属型铸造。
Diesel pump housing CRF_1-110-01 Department of the newly developed company civilian diesel pump (high horsepower) the main components, casting quality is related to pump performance and development prospects, the original use of unilateral gap casting low yield, scrap rate as high as 85%, the right After casting casting process improvement rate as high as 97%. Casting process analysis and technical requirements Diesel pump housing. Casting material ZL-101, castings weight 12.7kg, with 0.3MPa air pressure check the inner cavity and hole in kerosene, the time to maintain 3min. According to the casting structural characteristics and technical requirements, in order to ensure the tightness of the casting requirements, the use of metal casting.
