标准型恩氏粘度计是用于测定石油产品粘度的计量仪器。它的工作原理是:当试样在某温度时,从恩氏粘度计流出200ml所需要的时间与蒸馏水在20℃流出相同体积所需要的时间[称为粘度计水值,秒]之比,为该试样在t温度时的思氏粘度。恩氏粘度计结构简单,使用方便,除了用于测试石油产品粘度外,还广泛应用在化工、食品、纺织、医药等行业,作为上浆液、明胶、试剂等液体的粘度测定。 GB 266—77石油产品恩氏粘度测定法规定,被测试样在温度t时的恩氏粘度E_t,按下式计算:
Standard Engne viscometer is used to determine the viscosity of petroleum products measuring instruments. Its working principle is: When the sample at a certain temperature, outflow from the Ethnographic Viscometer 200ml time required for distilled water to flow out of the same volume at 20 ° C [called the viscometer water value, the second] ratio, The sample in the t temperature when the Viscosity. Engler viscometer simple structure, easy to use, in addition to testing the viscosity of petroleum products, but also widely used in chemical, food, textile, pharmaceutical and other industries, as the sizing agent, gelatin, reagents, such as liquid viscosity measurement. GB 266-77 oil products Engler viscometry provides that the test sample at temperature t Engler viscosity E_t, calculated as follows:
