Design And Implementation Of Quality Inspection And Maintenance Training System Of Heat Exchanger Based On Virtual Reality Technology

Heat exchange equipment is the main equipment to improve energy utilization rate in industrial production.It can transfer part of heat of hot fluid to cold fluid,make the fluid temperature reach the specified index of industrial process,meet the requirements of process production conditions.In the supply chain of heat exchange equipment in China's iron and steel enterprises,the logistics companies of iron and steel enterprises are generally responsible for equipment quality inspection,and the workshop inspectors in iron and steel enterprises are responsible for the daily use,maintenance and maintenance of heat exchange equipment.This is two key links,and it is very important to control the quality and maintain the quality correctly and timely to ensure the normal production of steel enterprises.In order to solve the problems of quality inspection and effective maintenance of heat exchange equipment in iron and steel enterprises,a training system for heat exchange equipment quality inspection and maintenance is designed and developed based on virtual reality technology.The main work completed is as follows:1.the function of the heat exchange equipment quality inspection and maintenance training system is designed and realized,including:system management module,component warehousing management module,equipment manufacturing module,equipment quality inspection module and heat exchange equipment maintenance and maintenance training module;through recording the various links from the storage of heat exchange equipment elements to the equipment delivery,the whole process of the components from warehousing to delivery can be realized Tracing to the source.The equipment manufacturing parameters are inspected by the equipment quality inspection module,and the maintenance and maintenance training module of the heat exchange equipment is used to train the maintenance and maintenance of the heat exchange equipment.2.the training system of maintenance and maintenance of heat exchange equipment for spot inspectors in steel enterprises is designed.The basic concept of graphic and graphic heat exchange equipment and the structure display of 3D scene heat exchange equipment are included.In particular,the three-dimensional scene of simulated maintenance operation is established for common problems of heat exchange equipment.In view of the three kinds of heat exchange equipment,which are the most commonly used plate heat exchanger,tube heat exchanger and combined heat exchanger,the three-dimensional model of 10 kinds of heat exchanger equipment,more than 40 kinds of heat exchange equipment components and PBR material library 3dhex are established.3.combining immersion virtual reality head on display,the design and implementation of VR scene display and VR scene natural interaction mode are completed.In order to make the maintenance personnel better understand the heat exchanger,master the structure and principle of the heat exchanger,and carry out the correct maintenance of the heat exchanger,14 VR training scenarios are established.It includes the common problems and treatment methods in the daily use of heat exchange equipment.Through VR simulation operation,the operation ability of maintenance personnel can be improved.4.the verification and analysis of the above three work have been completed,and the expected design objectives are achieved.
