Build A Process FMEA For A Dosing Pump
Apply process FMEA logic to prioritize failure prevention for a chemical dosing step.
Catalyst dosing pump P-18 can over-deliver catalyst during polymer batch step 4, pushing viscosity toward the upper specification and increasing heat-release rate. Process FMEA: function -> failure mode -> effect -> cause -> current controls -> severity, occurrence, detection -> action. Jumping straight to more calibration because it sounds like a pump control, without checking whether the actual failure mode is setpoint, connection, material, or detection. Define the function P-18 must deliver 2.0 kg catalyst to R-22 over 12 minutes after monomer conversion reaches the approved range. A clear function anchors the FMEA. If the function is vague, every later…
