Contaminated water test rig (particles – solid contaminant) 

Purpose designed and built test rig for testing operational conditions and wear measurements of sliding couple.

In typical case journal diameter is 65 – 70 mm and specific pressure up to 1 MPa.

The test rig was designed for water lubrication. Usually particles of mineral origin are used.

The test rig was used in commercial tasks and research [1][2]
