How to select grease according to drop point
When selecting grease, the main consideration should be given to the working condition (load, speed, temperature), working state (continuous operation, intermittent operation, vibration and impact, etc.) and working environment (humidity, temperature, air pollution degree, etc.) of the friction pair.
The use temperature of grease should be at least 20-30 degrees lower than its dripping point
When using at high temperature, fat with good oxidation resistance, small evaporation loss and high drop point should be selected; In the use of low temperature, should choose low starting moment, similar viscosity small fat, such as compound oil based oil fat.
SH3498 automatic wide temperature drop meter (Shandong Shentai Instrument Co., LTD. Research and development) in line with ASTM D2265 standards with a microprocessor as the core, set mechanical, optoelectronic and micro detection technology in one, with automatic temperature control, automatic adjustment of temperature rate, automatic detection and record drop point data, automatic printing output and other functions, The measurement of wide temperature drop point was completed.
