定量设备在砂处理系统中占有重要的地位。我厂根据铸件生产的需要将普通辗轮式混砂机经过改装用于混制树脂砂,开始时配砂沿用容积式定量斗,由于定量准确性不高,造成树脂砂质量不稳定,操作难以掌握。针对这个情况,从准确性,可靠性和维修方便等方面要求综合考虑,自行设计和制作了杠杆秤,并将其与定量斗组装在一起,成为杠杆秤称量器,
Quantitative equipment in the sand handling system occupies an important position. I plant according to the needs of the casting production will be ordinary roller-type sand mixer modified for mixed resin sand, the beginning with sand volumetric volume bucket used, due to the quantitative accuracy is not high, resulting in unstable resin sand quality, difficult to operate grasp. In response to this situation, from the accuracy, reliability and ease of maintenance and other requirements of a comprehensive consideration, to design and manufacture of the lever scale, and quantitative bucket assembled together to become a lever scale weighing device,
