Abstract:
In the modern industrial world lubricating greases are a necessity for the assurance that vehicles and machinery are operating to their fullest potential. Lubricant greases are composed of base oil, thickeners, and additives which can yield varying performances given unique characteristics contingent on the type and proportion of each of the three components in each grease. However, most of these greases in practical use are optimized for ambient temperatures and would become viscous in low temperatures causing pumpability and machine performance to suffer due to decreased lubricating effect of the grease throughout a vessel. Commercial lubricant greases optimized for low temperatures are rare due to the lack of instruments able to properly test lubricants according to the DIN51805 Kesternich method to ensure validity of experimental results. The K95300 Low Temperature Grease Flow Tester has been developed in accordance with the Kesternich method in order to overcome this deficiency and provide an economic and safe way to measure the flow properties of various lubricating greases in extreme cold temperatures to find which are most suitable for operational use. This poster will examine how this instrument can reliably determine the flow properties of various lubricating greases at adjustable cold temperatures in a manner pursuant with the Kesternich Method.
