Koehler润滑脂抗水淋性能测定仪K19200
符合美国ASTM D1264, D4950; IP 215; FTM 791-3252
Rotates a lubricated ASTM ball bearing at 600rpm in a modified bearing/housing assembly while impinging the bearing with a jet of water at the specified flow ratetemperature. The tared bearingbearing shields are weighed before installation in the bearing housingagain after testingdrying to determine the amount of sample loss. Consists of reservoir, bearing housing, circulation
systemdrive motor. Reservoir is equipped with cartridge heater, thermoregulatorthermometer port for accurate temperature control at 100°F175°F (38°C79°C) per ASTM specifications. Circulation system includes constant velocity carbon bearing gear pump, valvesflowmeter directing a controlled water flow to a capillary (1mm) spray nozzle aimed at the bearing housing. Rugged 1/3hp drive motor rotates test bearing at 600rpm while driving the circulation pump. A two-pulley system permits independent pump operation to circulate water while heating it to test temperature. Mounted on a finished steel base with locating feet for permanent benchtop placement.
