影响科氏质量流量计振动管磨损的若干因素研究

摘要

黏性流体和被测流体中的固相颗粒对科里奥利质量流量计(以下简称科氏质量流量计)振动管内壁均存在磨损作用,振动管的磨损状态对流量计离线标定、故障诊断和基于振动的流体黏度的测量存在一定的影响.基于固相颗粒对管道的磨损机理,讨论了影响固相颗粒对流量计振动管磨损的几种因素.提出了减小振动管磨损速度和延长流量计使用寿命的措施建议.%The vibrating-tube of Coriolis mass flowmeter(CMF) is abrased by viscous fluid and solidparticles in measured fluid, the off-line calibration, fault diagnosis and fluid viscosity measure based on vibration are affected by the abrasion state in inner wall of CMF. Discuss and analysis the factors influencing on the vibrating-tube's abrasion of flowmeter base on the abrasion mechanism. Give some measures to reduce the wear speed and prolong the service life of flowmeter.
