本文叙述了用毛细管法进行润滑油压粘关系测试的基本原理和试验设备。给出了压力至560kgf/cm~2范围,20号机械油和20号液压油的压粘关系的测试结果,并对结果进行了讨论分析。
This paper describes the basic principle and test equipment for testing the relationship between pressure and viscosity of lubricating oil by capillary method. The test results of the pressure-viscosity relationship between the mechanical oil No. 20 and the No. 20 hydraulic oil are given in the range of 560 kgf / cm ~ 2, and the results are discussed and analyzed.
