Application

The Impression Creep Test Rig is designed to provide solution for maintaining constant loads for long term creep & stress rupture testing applications of metallic materials in accordance with ASTM E 139. These tests can run from only a few hours up to and exceeding 10000 hours. The long duration of these tests makes the lever arm loading system with dead weights.

Conforms to ASTM G 133-05 Repeatable friction & wear measurement Independent proven repeatability Easy to calibrate Compact standalone bench top system

Application

• The air jet erosion tester is used to test the erosion resistance of solid materials to a stream of gas containing abrasive particles.

• Materials such as metals, ceramics, minerals, polymers, composites, abrasive and coatings can be tested with this instrument.

• The test specimen, temperature, angle of incidence of the jet stream, abrasive particulate speed and flux density, can be varied to best simulate actual conditions.

Application

The journal bearing test rig for investigating the distribution of pressure in slide bearings the principal of hydrodynamic lubrication. The distribution of pressure & the carrying capacity can be determined on a sliding bearing model at different bearing loads & speeds.

Learning objectives/experiments

• Relocation of the shaft journals in relation to speed

• Pressure distribution in the bearing with constant load and at various speeds

• Critical speed in relation to load

• Critical speed & viscosity in relation to oil temperature

Application
To Test the abrasive resistance of solid materials to abrasive dry sand compositions. Materials such as metals, minerals, polymers, composites, ceramics, abrasives and thick coatings can be tested with this instrument.
To develop a comparison table for ranking different materials with respect to each other, it is necessary to convert this mass loss to volume loss to account for the difference in material density.
