问:传统粘度检测方法有哪几种?答:传统粘度检测方法有细管法,旋转法,落体法,振动法四种。问:各种检测方法的特点?答:细管法的测量精确度高(达1%),可实现连续测量,用于检测牛顿流体的绝对粘度和非牛顿流体的表观粘度;缺点响应时间长,测量易受流体中的杂质、灰尘的影响,体积较大,安装不方便,成本较高。旋转法的优点是可直接插入流程管道或反应装置的流体内测量粘度,测量精确度为2%～3%,响应时间快;缺点是必须用于层流区。落体法的特点是结构简单,工作可靠,使
Q: What are the traditional viscosity detection methods? A: The traditional viscosity detection methods are thin tube method, rotation method, falling body method, vibration method four. Q: The characteristics of various detection methods? A: The thin tube method of measurement accuracy (up to 1%), continuous measurement can be achieved for the detection of Newtonian fluid viscosity and non-Newtonian fluid apparent viscosity; shortcomings response time Long, the measurement of fluid susceptible to impurities, dust, larger, inconvenient installation, high cost. The advantage of the rotary method is that it can directly measure the viscosity in the fluid of the process pipe or reaction device with the measurement accuracy of 2% -3% and the fast response time. The disadvantage is that it must be used in the laminar flow area. The characteristics of falling body method is simple structure, reliable work, so
