Investigation on the Friction Characteristics of Complex Calcium Sulfonate Grease Under High Temperature and High Pressure
The friction characteristics of lubricants under high temperature and high pressure are the core issues related to the operation and maintenance of equipment,and therefore it is crucial to find lubricant materials that can provide excellent lubrication performance under high temperature and high pressure.The HPT-5000 high temperature and high pressure friction characteristics test device was used to test the friction characteristics of calcium sulfonate complex grease at high temperature and high pressure,and compared with traditional lubricants.Under the conditions of 150 ℃,200 ℃,250 ℃ and 5.0 MPa,10.0 MPa,calcium sulfonate complex grease has better friction characteristics with better friction reduction and anti-wear properties than conventional lubricants.This comes from the fact that the calcium sulfonate complex grease can form a stable composite lubricating film,which expands the potential of calcium sulfonate complex grease under high temperature and high pressure.(Charts4 Table1 References12)
