科里奥利质量流量计:固体颗粒与沉积需要注意什么?

颗粒磨损堵塞及沉积需分别评估,不能只说浆料可测。

直接回答

颗粒磨损堵塞及沉积需分别评估,不能只说浆料可测。

颗粒的堵塞、沉积和冲蚀是不同边界。

判断依据与适用条件

诊断的依据是同一测点异常与正常状态的差别。保留异常发生前后的工艺和原始响应,再决定哪个因素值得验证;能随条件重现的关系比一次恢复更有价值。若几项因素同时变化,应先拆开证据,避免直接指认单一原因。

在科里奥利质量流量计中,本题的检查对象是固体颗粒与沉积。需要取得的证据是:列明粒径、硬度、浓度及停留状态。污染检查需说明附着位置与性质。导电膜、绝缘膜、增加摩擦的沉积和改变几何的硬垢不能用同一措施解释;清洗后恢复只支持污染相关线索。还应核对敏感表面是否被损伤以及再次附着的时间,避免靠周期调零掩盖累积变化。

针对本题怎样核查

  • 先提供粒径硬度和沉降。记录振动相位、密度与驱动诊断,标明其中哪些是本次实际取得的,未提供的诊断或功能不得当作本机已有能力。
  • 记录固体颗粒与沉积出现的时间、运行阶段和最近改动,同时保存诊断与原始值。
  • 围绕“列明粒径、硬度、浓度及停留状态”建立前后对照,参照应适用于当前对象及条件。比较期间保留固体颗粒与沉积的原配置及工艺状态,一次只处理已有证据指向的因素。

假设案例:如何作出判断

考虑“低速停留后颗粒积在测量管”这一现场疑问。假设停流后固体沉在弯管,电子自检通过仍不能证明通道几何与充满状态正常。

这个结果支持的是一个可验证的线索。

确认结果与交付记录

这道题的结果应回到“固体颗粒与沉积”:结论旁写出支持它的列明粒径、硬度、浓度及停留状态,并注明实际覆盖的状态、参照依据与仍待确认项目。报告保留固体颗粒与沉积的原始记录和配置,不能把输出端的一次模拟签成未实际覆盖环节的通过。
