WATER WASHOUT CHARACTERISTIC OF LUBRICATING GREASE
COMPLIANCE*
Conforms to ASTM D1264, D4950; IP 215; FTM 791-3252
APPLICATION
A grease sample is packed in a ball bearing and subjected to a steady water stream under controlled test conditions. The percentage of grease washed out in a one hour period is determined by weight.
INSTRUMENT DESCRIPTION AND CONSTRUCTION
A lubricated ball bearing is rotated at 600rpm ina modified bearing housing and sprayed with a water jet of fixed flow rate and temperature.The difference of weight of the greased bearing, before and after testing and drying, determines the sample loss. Consists of reservoir, bearing housing, circulation system and drive motor.
Reservoir is equipped with digital temperature control to maintain (38°C and 79°C) per ASTM standard. Circulation system with a pump and flowmeter directs a controlled water flow at the bearing housing. A 1⁄4hp motor runs the test bearing at 600rpm. Mounted on a Stainless steel base with antivibration mounts.
POWER : 230V, 50Hz, 1 Ph, Ac.
