型砂紧实率控制仪

Sand Compactability Control Device

介绍了一种用于大型铸造车间的型砂质量控制仪。它是由检测其紧实率而控制型砂含水量的仪器。本仪器除了有可靠的机械检测部分外，中心控制系统采用可编程控制器（ＰＬＣ），提高了本机的抗干扰能力。

This paper introduces a type of snnd quality control device, which is used in largefoundries to control the water content in sand by measuring its compactability. Not only doesthe device possess a reliabe part of mechanical check,its central control svstem also empIoysaprogrammable logic conroller,thus,its capability of resistance against interference in-creasel.
