Product Outline
Conventional CYJ pumping units with walking beams 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), Pumping units with Walking Beams (SY/T5044) and other related standards, and have acquired the authorization to use Official API Monogram.
In addition to the conventional pumping unit with walking beams, to meet energy-saving requirements of clients, Cavaville has also developed out phase beam balanced pumping unit, double horse-head pumping unit, diameter and moment adjusting pumping unit, crown sheave pumping unit and other energy saving pumping units.
Technical Features
1. Modular and virtual manufacturing technologies are adopted in design, so that the structure of products is optimized and components are highly standardized, generalized and seriated.
2. Key structural elements are subject to finite element analysis to ensure stable performance and high reliability.
3. The entire machine features simple operation and maintenance and extended service life.
4. 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.
5. The walking beam adopts box-type or I-beam structure, which has high strength, good rigidity, and large bearing capacity.
6. The horse head adopts lateral rotary structure. During workover operation, the horse head will turn 90°, so that the wellhead is open to facilitate operations.
