Modera Casting 1990,6.-68 高质量的型砂需要过筛、冷却、输送和混辗。如果把湿砂设备看作砂处理系统的骨骼和肌体,控制系统则是其中枢神经。设计和维护得当的控制系统能保证整个设备的安全运行和输送适合造型机和生产各类铸件要求的型砂,开机率高、维修费用低。湿砂控制系统通常由可编程序控制器和电机控制中心来实现。可编程序控制器提供输送
Modera Casting 1990, 6.-68 High quality sand requires sifting, cooling, conveying and mixing. If the wet sand equipment is considered as the skeleton and body of the sand treatment system, the control system is its central nervous system. The well-designed and maintained control system ensures the safe operation of the entire plant and the transport of sand suitable for molding machines and for the production of all types of castings, with high operating rates and low maintenance costs. The wet sand control system is usually implemented by a programmable logic controller and a motor control center. Programmable controller to provide delivery
