PCM WEBINAR - Rotor sizing

Описание: Progressing cavity pumps are an excellent form of artificial lift (AL) in many applications. While they technically out-perform other AL systems in certain applications (for example pumping very viscous fluids or fluids with high solids content), they can have better economics than other AL systems in a wide range of applications. However, good economic results depend on good pump performance and run-life. One thing that makes PCPs different from other AL systems is the elastomer, and the interference fit between the rotor and stator. Elastomers behave differently from steel, and in particular, they can expand due to both chemical and thermal effects. This expansion affects the fit between the rotor and stator. Getting the fit right in consideration of this expansion is important in achieving both good performance and good run-life.

In this webinar, we have discussed the importance of rotor sizing, how rotor sizes are selected, and what the effects of different rotor sizing can be. We have looked at how PCM selects rotor sizes, as well as other methods that are used. We also looked at how elastomer pump and rotor geometry affect rotor sizing.

We went beyond theory and look at operational aspects to provide some advice and recommendations on selecting, operating, and optimizing pumps both in new and existing applications.
