What is the difference between the anti-water spray performance and the anti-water spray performance of grease? How to ensure the accuracy of its measurement results?

What is the difference between a grease's water spray resistance and its water spray resistance?

The water spray resistance of the grease is the ability of the grease to resist the impact of water in the running bearing, while the water spray resistance of the grease is the ability of the grease to resist the impact of water mist on the plate. in:

1) The water-spray resistance of lubricating grease is determined by SH/T0109-2004 "Measurement of Water-spray Resistance of Lubricating Grease";

2) The water spray resistance of lubricating grease is measured by SH/T 0643-1997 "Measurement of Water Spray Resistance of Lubricating Grease";

The schematic diagram of the test method for the water spray resistance and water spray resistance of lubricating grease is as follows. Both test methods need to weigh the change of grease quality before and after the test, so the key to improving the accuracy of the test results is to pay attention to the operation during the weighing process. In addition, because the lubricating grease will pollute or even block the nozzle under the drive of water, causing failure, therefore, carefully cleaning the equipment before and after the test can reduce the test error.
