API belt-driven pumping unit
- Product Details
Product Introduction:
The API series beam pumping unit adopts a crank balance method and is the most common and widely used ground power equipment in rod oil production operations in oil fields.
The product complies with API Spec 11E "Technical Specification for Pumping Units" and other relevant standards, and has obtained an API Monogram Usage License.
By utilizing modular and virtual manufacturing technology for design, the product structure is optimized, and the degree of standardization, generalization, and serialization of components is high.
The finite element analysis of the bonded structural components shows stable performance and high reliability.
The reducer adopts a symmetrical split involute double arc herringbone gear transmission, which has good sealing, low noise, smooth rotation, and is reliable and durable.
The whole machine is easy to operate, easy to maintain, and has a long service life.

Product Features：
Efficient and energy-saving: Compared with conventional beam pumping units, the energy-saving rate can reach 10% -40%, and long-term operation can significantly reduce the power consumption cost of oil fields;
Small footprint: The body adopts a compact design, with low requirements for footprint and well spacing. A single device does not need to reserve too much space, perfectly adapting to the dense layout of clustered wellheads in the well site;
Stable and reliable operation: Adopting belt transmission and optimized reversing structure, the stroke is low and long during operation, and the reversing process is smooth, which can reduce the impact on the pumping rod and reduce the risk of rod and tube wear;
Low maintenance frequency: Key components such as wear-resistant bearings, long-life belts, and heavy-duty chains are designed with high durability, which is not easily damaged and does not require frequent downtime for maintenance, reducing maintenance manpower and time investment;
Strong compliance: The design and production fully comply with the American Petroleum Institute (API) specifications, meeting the technical standards and admission requirements of mainstream oil fields at home and abroad.
Fully mechanical reversing system：
Fully mechanical structure, no maintenance required within 10 years;
The reversing system ensures smooth transmission;
Adopting a conventional spiral two-stage reducer, paired with chain transmission. Increase the recovery efficiency of oil fields
