Water Spray Off Tester

WATER SPRAY OFF TESTER As per ASTM D 4049 Water spray off tester evaluates the ability of a lubricating grease to adhere to a metal surface when subjected to a direct water spray under controlled conditions. The percentage of grease sprayed off a stainless steel test panel after a specified period is determined by weight. - It Conforms to ASTM D4049 specifications The equipment including spray chamber, delivery system and constant temperature reservoir. It Sprays water at the specified rate and temperature on a test panel coated with sample grease. To test for water spray resistance, fill reservoir with 8L of tap water and set the temperature comtroller at test temperature. Circulate the water through the system to attain temperature equilibrium and insert the coated test panel in the spray chamber. Adjust water spray to 40psi (276kPa) and continue for 5 minutes. Water spray system includes 1.3hp positive displacement pump; spray nozzle with snubber fitting: 0-60psi pressure gauge; bypass valve; shut-off and drain valves; and flexible high pressure water lines. Hinged acrylic spray chamber cover is recessed into the chamber housing to insure watertight operation. Standardized grease application fixture coats test panel with the required thickness of sample grease. Uses tap water; does not require water hook-up. The system includes: Stainless steel test panel Grease application fixture Thermometer holders Pressure gauge Salient feature – Dital Temperature Controller Unit for temperature accuracy 0.03°C Temperature range : 35.00 to 150.0°C Power supply: 230 Volt AC. 1 phase, 50Hz Country of Origin : India
