本文叙述了砝码加载式高压毛细管压粘仪的基本原理。给出了10号机械油、25号变压器油、20号机械油和20号汽轮机油在不同温度下的压粘关系,测试最高压力为0.1GPa,测试温度为13℃、40℃和100℃。测试结果表明:这4种矿物油的压粘系数α随温度的升高而变小。
This article describes the basic principle of weight loaded high pressure capillary pressure sticky instrument. The pressure-viscosity relationship of 10 # mechanical oil, 25 # transformer oil, 20 # mechanical oil and 20 # turbine oil at different temperatures is given. The maximum pressure for testing is 0.1 GPa and the testing temperature is 13 ° C, 40 ° C and 100 ° C. The test results show that: these four kinds of mineral oil pressure-viscosity coefficient α decreases with increasing temperature.
