The water resistance tester for lubricating grease adopts a digital temperature controller with precise temperature control. The stainless steel bath and organic glass buckle box not only extend the service life of the instrument, but also visually test the effect. It adopts an efficient magnetic circulating water pump and adds a circulating water volume adjustment knob. The adjustment knob, combined with the water flow meter, can achieve a water spray flow rate of 18L. This instrument adopts a toothed belt transmission device to make the test speed of the instrument 600r/min. To facilitate user operation and use, this instrument has added a microcontroller timer, which reports once per hour.
The water resistance tester for lubricating grease consists of a water reservoir, a bearing box, a circulation system, and a drive motor. The water reservoir is equipped with a cylindrical heater, temperature regulator, and thermometer port for accurate temperature control at 38 ℃ and 79 ℃ according to standard specifications. The circulation system includes a constant speed carbon bearing gear pump, valves, and flow meters, which direct the controlled water flow to a capillary (1mm) nozzle aligned with the bearing housing. Drive the motor to rotate the test bearing at a speed of 600 revolutions per minute while driving the circulation pump. The instrument system allows for independent pump operation of circulating water while heating to test temperature. The instrument host is installed on a steel base, and the positioning feet can fix the workbench.
Features of the Lubricating Grease Water Resistance Tester:
