回转式自动粘度计是化工生产中重要的仪器设备,而扭力管是粘度计的心脏部件。该部件容易损坏,价格昂贵,每支四千余元,且制造困难,目前尚需进口。本厂使用日本进口自动粘度计一台,在运行过程中,当测量介质粘度波动过大、操作不当或其他原因,扭力管扭角达到2°的永久变形,粘度指示达到最大值,扭力管即失去检测作用, Rotary automatic viscometer is an important chemical equipment in the production equipment, and the torsion tube is the heart of viscometer components. The parts are easily damaged, expensive, each four thousand yuan, and manufacturing difficulties, the current still need to import. The factory uses a Japanese imported automatic viscometer, during operation, when the measured medium viscosity fluctuations too large, improper operation or other reasons, torque tube torsion angle of 2 ° permanent deformation, the viscosity indicates the maximum, the torque tube that Loss of detection,
