Water Washout Tester

Characterization of the water leaching of lubricating greases

Properties

Control settings for water temperature
Fine adjustment of water flow and test ring speed
fast heating time

Description

The test bearing is mounted on a hub, and rotated by an electric motor and toothed belt at 600 rev/min. A peristaltic pump draws heated water from the tank, through a filter, and sprays it, via a 1mm capillary, onto the face of the bearing at a flow rate of 300ml/min. The temperature of the water is digitally controlled in the range of ambient to 80°C. The water containing washed out grease is collected in the tank, filtered and recycled. The front panel has controls for water temperature, fine adjustment of water flow rate and bearing rotational speed, and a jet bypass switch to allow pre-heated water to circulate without passing through the jet.
