黄河科技学院毕业设计说明书 第 III 页 对辊机电气系统设计摘 要对辊机也叫双辊破碎机或者辊式破碎机，是利用高强度耐磨合金磨辊相对旋转产生的高挤压力来破碎物料。物料进入破碎腔以后，受到磨辊的相对旋转的挤压力作用，在挤轧和啮磨下，将物料破碎成理想颗粒排出。用于在水泥，化工，电力，冶金，建材，耐火材料等工业部门，破碎中等硬度的物料。科学技术的不断发展，极大地推动了不同学科的交叉与渗透，导致了工程领域的技术革命与改造，使工业生产迈入了机电一体化的发展阶段，也为对辊机电气控制系统设计提供了强硬的技术支持。本次设计中，在安全性方面，采用了对射式光电开关进行控制，并且通过在控制现场设置启动、停止按钮来进一步对安全性进行提高；在可靠性方面，采用先起动冷却泵电动机再启动主电动机的控制方法，很大程度上延长了对辊机的使用寿命。本次设计内容主要有四部分：首先，通过对辊机电气控制系统的调查分析和实际情况，确定最合理的电气控制系统；其次，通过框架系统、传动系统和间隙调整系统的分析比较，确定传动形式及电动机的型号；再次，通过计算各电气元器件的参数，确定其型号；最后，电气控制系统的工艺设计和电气控制柜的设计。本设计是在已有的对辊机电气控制系统和实际工程需要的基础上进行的，经过改进后可以应用于工业生产，具有一定的应用价值。 关键词 ：电气控制，传动系统，对辊机The Electrical System Design for the Roller MachineAuthor : Mo YanliTutor : Mu GuohuaAbstractThe roller machine is also called as roll-on roll crusher or dual-roll crusher,which squeezes the material to use the high pressure of high trength wear-resi-stant alloys roller relative rotation.After the material enters the crushing chamber,the material is squeezed by the roller of the relative rotation.In rolling mill,the materials will be broken into particles. It is used in cement, chemicals, power, metallurgy, building materials, refractories, and other industrial sectors, for braking middle hardness of materials.The continuous development of science and technology, which greatly promoted the cross-penetration of different disciplines, has led to the technological revolution and the transformation of the fields of engineering, industrial production has entered a stage of development of mechatronics , but also for the roller machine electrical control system designa strong technical support. This design, in terms of security, control of the photoelectric switch on the radio, and through the control field is set to start and stop buttons to improve further on the security; in terms of reliability, the first motor starter cooling pump start the main motor control method, greatly extending the service life of the roller machine. The design elements have four parts.Firstly,through the investigation and analysis of the electrical control system of the roller machine,I determine reasonably the disign plan of the electrical control system.Secondly, through the compare and analysis of the frame system, transmission system and gap adjustment system ,I determine the transmission form and model of electromotor.Thirdly, through the parameters of the electrical components ,I determine their type.Finally,I finish the design of the electrical control system and the design of electrical control cabinet.This design is based on the electrical control system of the roller machine and the actual works.
