This feature strengthens the ends of the cylinder and prevents the extrusion of the soft lead inner liner against the covers. Test Devices designs armor cylinders to be fully elastic in both shear and tension, and they are reinforced at the top and bottom by a retention ledge. It is designed to yield only under overload conditions, with an 18% elongation. The single piece forging eliminates welds, reducing stress concentration and strength issues. The steel armor cylinder Test Devices uses for the primary containment of an uncontrolled burst is forged and heat treated. Key FeaturesĪ robust armor cylinder is mandatory for long-term safety of the machine and the operator. Our 600 Series turbines are designed specifically for proof and burst testing applications. Vacuum System: Includes the pump/blower set, providing a vacuum level below 400 milliTorr, together with controls and level gauge.ĭrive Systems: Test Devices offers a range of drive options for both air turbine drive systems and direct electric motor drive systems, covering the speed range up to 160,000 rpm. Standard ModulesĬontainment Chamber: Industry leading containment capability designed for high energy applications. Test Devices’ Proof/Burst Spin Test Systems incorporate all basic spin pit capabilities in an efficient and cost-effective system to perform proof or burst tests of high-speed rotating components to meet R & D or production requirements. Burst tests are run to establish the operation safety margin for components and understand the mechanism by which components fail (failure analysis). Proof tests (also known as “over-speed” and “pre-spin” tests) are typically run to prove component integrity following preliminary machining or component repair, or for pre-stressing rotors prior to final machining. Proof/Burst Spin Test Systems are used to perform a few specific spin tests.
