磁鼓號
英文
drum number-
This control system adopts creditable plc for real control ; it sends many simulating signals collected by old sand temperature of inlet, suction opening temperature of double disk, inner sand temperature of double disk, current of mainframe and current of fan ; meanwhile, the operation signal and switching value signal outputted by material movement transducer is inputted to switching value module of plc ; it gets evidence of water feeding after cpu account ; the operation result of cpu is outputted by switching value of plc to control unlock combination of coarse, middle and thin water feeding electromagnetically operated valve and then gets different water feeding quantity
該控制系統採用高可靠性的plc可編程序控制器進行實時控制，傳感器所採集的入口舊砂溫度雙盤抽風口溫度雙盤內砂溫主電機電流及鼓風機電流等模擬量信號直接輸入plc的模擬量採集模塊，同時加砂設備運轉信號及加砂設備物料移動檢測傳感器發出的開關量信號輸入plc的開關量模塊，由cpu獲取經運算而得到加水計算依據， cpu運算結果直接由plc的開關量輸出控制粗中細加水電磁閥的開啟組合，而得到不同的加水量。Firstly, the paper introduces the theory of the insb magnetosensitive characteristics. and the distributing of the magnetic field of magnetic drum of magnetic encoder is calculated, and the gap between magnetic drum and head affecting magnetic encoder ' s function is analyzed, the velocity of magnetic drum affecting magnetic encoder ' s function is analyzed. the design is based all these analyzes
本文首先介紹了insb磁敏效應的基本原理，對編碼器磁鼓的外圍磁場進行了計算分析，分析了磁鼓與磁頭間隙對磁頭輸出信號的影響，分析了磁鼓轉速對磁頭輸出信號幅度的影響，並根據這些計算和試驗分析，設計了磁編碼器的結構。
