熔模铸造制壳用撒砂机,目前国内使用的主要有两种,即沸腾式砂床和雨淋式撒砂机。实际生产应用表明,两者各具特点。我们在认真分析机械振动雨淋式撒砂机优点及不足的情况下,设计了电机直线振动雨淋式撤砂机,并成功地在北京发电设备修造厂实际生产中得以应用,效果良好。 Casting shell sand with sand making machine, currently there are two main domestic use, that is, boiling sand bed and rain sprinkler. The actual production shows that the two have their own characteristics. We carefully analyze the advantages and disadvantages of mechanical vibration rain and sand sanding machine, the design of the motor linear vibration rain and shovel sand removal machine, and successfully in the Beijing power plant repair plant in the actual production can be applied, the effect is good.
