Based on the factual situation of the plant , this paper found out the shortcoming in the drying process , analyzed main disadvantages in the course of using , the measures and approaches to rectify these disadvantages were presented 本文根据本单位的生产实际情况,找出了干燥环节存在的不足,分析了干燥炉在使用过程中的主要缺陷,提出了纠正这些缺陷的措施与途径。
There are two drying furnaces in electric company of panzhihua iron & steel co . , which were employed for drying the windings of motor , transformer and other electrical equipment in order to satisfy the insulating performance and intensity requirement of works 攀钢电气公司有两台干燥炉,用于干燥电机、变压器及电器线圈等产修品,以满足工件的绝缘性能和强度要求。
In technical aspect , changing the sealed furnace into heat - air circulation structure , it makes the temperature of the drying works be average , the humidity is got rid of in time which affecting the quality of the product 在工艺上,将原封闭的干燥炉结构改为热风循环干燥炉结构,这样有利于改善原干燥物品在炉内温度不均匀、潮气不能及时排除等情况而影响产修品质量。

For many years , the drying furnace has been adopted with sealed structure and electrical heated , dial instruments are used to control the temperature of the drying furnace and to keep it invariable . parameter setting is inputted by manual method , heating time is completely controlled by operators ’ experiences or their moods , meanwhile , its control function is singular , not only having no automatic heating time and insulating monitoring , having no drying process monitoring , but also having no function of automatic recording and report printing , the workers ’ labor intensity is bigger . thus two abnormal situations are always come forth , one is the insulating performance and intensity of works cannot be guaranteed reliably , it perhaps need to be dried repeatedly , the other is always to extend the drying time in order to ensure the drying quality 多年来干燥炉一直采用闷罐式结构和电加热方式,温度控制采用指针式温度控制仪表来实现炉温的恒定,其参数设定由人工输入,时间控制则完全凭操作者的经验、情绪来掌握,其控制功能单一,没有时间控制、绝缘自动监测功能,也没有干燥过程监视功能,更没有多要素记忆、打印存档功能,工人的劳动强度较大,所以就经常出现两种异常结果:一是工件的绝缘性能和强度得不到可靠保证,需要反复干燥;另一种是为保证干燥质量,往往要延长干燥时间。
The control system of furnace " s temperature has been widely used in every walk of life , as an important link of repair and manufacture of the electrical equipment such as electromotor transformer etc . , soaking lacquer drying craft has some especial requests on drying crafto this article starts with the analysis of drying chamber " s configuration , analyzed its configuration limitation and control function limitation according to the factory " s situation and advances the conception of heated air drying circulation , in addition , this article adopts an intellectualize a / d module , a development sampling tuning - voltage circuit , and presents the method to measure online the insulation resistance of products in order to improve constantly products quality 而浸漆干燥工艺作为电机、变压器等电气设备的修理、制造中的重要环节之一，对干燥过程的质量要求有一定的特殊性。该文从干燥炉的结构分析入手，联系到工厂的实际情况分析了结构功能缺陷和控制功能缺陷，提出了热风循环干燥的概念，同时，选择了较为先进的a d板卡、热电阻信号调理板等专业化智能卡，运用数字pid控制技术，构成了一个较有特色的计算机控制系统。此外，该文还从保证干燥品质量的角度，采用智能化交流模块和自制采样调压电路的方法，提出了在线检测产修品的绝缘电阻的方法和手段，以确保企业产品质量不断提高。
