| Machine-rocking pumps of balance |
|
Pumping units are walking beam individual drive of oil-well sucker-rod pumps used during oil well operation. Pumping unit is manufactured in two versions:
-with a low stand support and gear reducer mounted on pumping unit frame;
- with gear reducer mounted on the stand support where low seating of wheel provides for frame upper position relative to the foundation.
A four-linked transforming mechanism of drive is implemented according to the asymmetric scheme that allowed to reduce the overall dimensions and the weight of pumping units, and also electric energy consumption. High reliability and durability of pumping units are guaranteed. The plant has been carrying out the modernization of pumping units production and can develop the output of the new types in agreement with both parties at the earliest possible date.
