The Leak Detection Methods And Equipment Design For The Welded Water Storage Heater

Tank water heater is mainly composed of a electric heater,a shell,a temperature controller,a pressure limiting valve，and the water inlet and outlet pipes and an inner tank. And the innertank is the key parts to the quality of electric water heater. For now, inner tank must be leakdetection after welding form the Production process. And the using leak detection equipmentis low degree of automation. In the inner tank production line is large labor intensity, lowproduction efficiency. For that, we develop the Four station leak detection equipment. Thispaper describes how to use of modern design means, for equipment design and development,and made a physical prototype, verify the design effect.This design through the use of SolidWorks software to model and virtual assembly forthe main parts of virtual prototype of the Four station leak detection equipment. Then useSolidWorks motion kinematic analysis, Focus on the equipment rotary motion characteristics.Lay the foundation of power equipment selection, determination of the motion parameter.This design also uses the SolidWorks simulation to statics analysis, check the partsstrength and stiffness of the main parts of the four station leak detection equipment. At thesame time carried on the optimized design for the base member, causes it to satisfy theperformance requirements to material cost reduction.On the basis of theoretical study and design, production an equipment, and track itoperation, Comparison of actual effect and design.
