摘要
附有测试棒的直流电动机,其负载(测试棒插入液体中)和空载时输入功率的差异与测试棒所受的负载转矩有关,而负载转矩又与液体的粘度有关.据此原理设计了旋转法粘度计,这种粘度计特别适用于研究电流变液的粘度随电场强度变化的规律.
For a direct current motor with an attached testing-rod,the difference of input power between load(when the testing-rod is inserted in the liquid)and non-load is con- cerned with the load moment of rotation of the testing-rod.And the load moment of rotation is concerned with the viscosity of the liquid.Thus the viscosity of the liquid can be measured.This kind of viscosimeter is especially applicable to the study of the rule for the change of the viscosity of “the electrorheological fluid”with the electric field.
