水泥的料位一般较难控制,因为它飞尘多,粘性强,导电性差,一般的如光电、感应等控制器经长期使用都会被水泥飞尘粘住,而失去控制能力。而输送水泥大都又采用风送,这给控制料位带来了更大的困难,所以绝大多数的散装水泥罐都没有料位控制,时常因为不能正确定料位而造成冒装或少装。冒装时会出现风送管受压过大而爆裂,水泥从顶口喷出造成浪费和污染,少装时又会出现生产急需时水泥供应不足,不能充分利用贮存罐的容量。目前虽有超声波、音叉振子等探测料位的,但终因设备复杂、成本高,操作麻烦等而不能被大量采用。这里介绍的是一种从实际工作中总结出 The cement material level is generally more difficult to control, because it has more dust, more viscous, and poor conductivity. General controllers such as photovoltaics and sensors will be stuck in the cement fly dust for a long time and lose control. Most of the cement is transported using air, which brings more difficulties in controlling the material level. Therefore, most of the bulk cement tanks do not have material level control, and they are often caused by failing to determine the material level. . In the case of reloading, the air-supply pipe will be over-pressurized and burst, and the cement will be ejected from the top opening to cause waste and pollution. When the equipment is installed, the supply of cement will be insufficient and the capacity of the storage tank cannot be fully utilized. Although there are currently ultrasonic and tuning fork vibrators for detecting the material level, they cannot be used in large quantities due to complicated equipment, high cost, and troublesome operation. Here is a summary from the actual work
