| Abstract: | After an analysis of the service performance of air balanced chain drive pumping units, measures were taken for changing the air balancing mechanism to weight balancing mechanism. And 202 air balanced chain drive pumping units were modified.Field data show that the failure rate of the modified weight banlanced chain drive pumping units is reduced by 70 percent or over. |
