Stirring commissioning plan and inspection items for reactors with packing and mechanical seals

Thread Content

I hope experts can share the stirring commissioning plan and inspection items for reaction vessels equipped with packing and mechanical seals. In particular, what parameters are generally checked regarding the installation accuracy of the stirrer? The following inspection items are included: temperature, vibration, noise, current, mechanical seal leakage, maximum speed, mixing test, insulation test, deviation of the external coupling position in the tank (horizontal and vertical directions), deviation of the internal coupling position in the tank (horizontal and vertical directions), radial deflection at the shaft seal, radial deflection at the lowest point of the shaft, positional deviation of the upper bearing relative to the frame, horizontal and vertical deviations of the lower bearing, clearance between the lower bearing and the shaft, shaft perpendicularity, clearance between the shaft end and the bottom of the tank, and eccentricity between the shaft end and the bottom hole. After mentioning so much, it’s unclear what the scope of application is, under what circumstances these inspections are necessary, when they can be carried out, and how they should be performed. I’d like to ask an expert. Thank you.
