经盐浴炉加热淬火的工件,其表面均敷着一层厚度不等的残盐,用碱水与中性盐的水解作用去除,或者喷砂冲刷工件来去除,都不能彻底除去。现介绍一种利用碱水水解和喷砂两者的优点,设计制造的半自动清洗机,如附图所示。其主要技术参数为: 溶液加热功率18KW,电热器5支,三侧面均布;喷头2个,上下布置,水孔ρ2.5×185个;喷水压力294～343KPa;工作室有效容积500×500×450mm。经一年的生产验证,清洗效果极佳。
The workpiece quenched by the salt bath furnace, the surface are coated with a layer of residual salt of varying thickness, with alkaline hydrolysis and neutral salt removal, or sandblasting erosion of the workpiece to remove, can not be completely removed. Now introduce a kind of using alkaline hydrolysis and sand blasting the advantages of both design and manufacture of semi-automatic washing machine, as shown in the figure. The main technical parameters are: solution heating power 18KW, electric heater 5, three sides are uniform; nozzle 2, up and down layout, water hole ρ2.5 × 185; water pressure 294 ~ 343KPa; studio effective volume 500 × 500 × 450mm. After a year of production verification, cleaning effect is excellent.
