Product Outline
Newly developed energy-saving API R pumping units with walking beams, similar in structure to conventional ones, are among the most common and most widely used power units in rod production on oil fields.
Products comply with Specifications of Pumping Units (API Spec 11E) and other related standards, and have acquired the authorization to use Official API Monogram.
Technical Features
1. Modular and virtual manufacturing technologies are adopted in design, and the products are similar in structure and movement characteristics to conventional pumping units with walking beams.
2. Reducers are driven by double-arc symmetrical split or involute herringbone wheels that are properly sealed and distinguished with low noise, smooth operation, reliable and durable service.
3. Cranks are in a contrary flexure angle so as to reduce the max. torque peak of reducers, increase the polar angle, enhance dynamic performance, cut down the power of power generating machines and amplify energy saving effects.
4. The structure of products is optimized, components are highly standardized, generalized and seriated, and the products feature easy operation and maintenance as well as extended service life.
