Quality Control of Vacuum Insulation Panels: An Instrument for Measuring Internal Pressure
Vacuum insulation panel(VIP)is mainly rely on its internal vacuum degree to improve the thermal insulation performance.Because the internal pressure value is the most important physical parameters of the characterization of vacuum insulation panels insulation performance,it is therefore very important to measure the internal pressure of vacuum insulation panel accurately.It is helpful to guarantee both quality and quantity of the vacuum insulation panels,and then can be widely used at many situations where heat insulation is needed.In the research of vacuum degree of vacuum insulation panels testing technology,this article devotes to the study of one instrument which can measure the value of internal pressure The instrument presented here can be used to measure the internal pressure of vacuum insulation panels,which is suitable for hard core materials.It can determine whether the vacuum insulation panels are qualified quickly.The instrument is manufactured by vacuum,CAM drive,sensor measurement and electric control systems.The mechanical part of CAM transmission is used as the core.Vacuum pump,laser distance measuring instrument,vacuum gauge and barcode printer.These functional components are controlled by single chip microcomputer to realize the automation.The presented method is newly-developed,more efficient and has the advantage of green environmental protection.It has been successfully developed to non-destructively evaluate the pressure in the vacuum insulation panels,fabricated on industrial scale,and is essential for reliable quality control of vacuum insulation panels.
