RPD-50 creep fatigue testing machine

1、 Application scope

RPD-50 creep fatigue testing machineMainly used for high-temperature alloys, titanium alloys, other ferrous and non-ferrous metal materialsCreep fatigueMechanical performance testing,Creep fatigue testasCreep fatigueZero crossing creep under tension and compression, creep-Fatigue, fatigue creepWaiting for the experimentThe process is either pulling or pressing, and the pulling and pressing can cross zero without any gap.The equipment fully complies withGB/T38822 Metal Creep Fatigue Test Standard.

Our newly developedRPD-50 creep fatigue testing machineThe creep fatigue series models are high stiffness dualColumn andMoving crossbeamforMovable structure，Perform zero crossing of tension and compressionCreep fatigue testAt that time, lower the upper crossbeam to reduce the distance between it and the workbench (lower crossbeam) (stabilizing the pressure bar), replace it with a dynamic rigid connection fixture, and then apply a certain amount of pre pressure to the connecting rod. Lock the clearance nut to achieve a seamless rigid connection structure, and replace it with a shorter high-temperature furnace. The above work is all aimed at reducing the instability phenomenon during the dynamic zero crossing test of the pressure bar.
