Title (EN) BEAM PUMPING UNIT WITH GEOMETRY OPTIMIZED FOR BEARING STRESS REDUCTION
(FR) UNITÉ DE POMPAGE À BALANCIER À GÉOMÉTRIE OPTIMISÉE POUR LA RÉDUCTION DE CONTRAINTE DE PALIER
Abstract:
(EN) A pump jack includes a number of standard components that have been sized and configured according to unique relative dimensions to produce a pump jack that reduces structural stress, increases bearing life and permits a lower cost of manufacture. These geometric ratios can be used to express the relative size and spacing of the crankshaft, crank arms, center bearing, equalizer bearing, walking beam and pitman arms. Pump jacks incorporating one or more of these geometric ratios can be sized and scaled for a variety of pumping applications.
(FR) Chevalet de pompage comprenant un certain nombre de composants standard qui ont été dimensionnés et configurés selon des dimensions relatives uniques pour produire un chevalet de pompage qui réduit la contrainte structurale, augmente la durée de vie de palier et permet un coût de fabrication plus bas. Ces rapports géométriques peuvent être utilisés pour exprimer la taille et l'espacement relatifs du vilebrequin, des bras de manivelle, du palier central, du palier de compensation, du balancier et des bielles pendantes Des chevalets de pompage renfermant un ou plusieurs de ces rapports géométriques peuvent être dimensionnés et mis à l'échelle pour diverses applications de pompage.
