Technical Performance Features
1. Designed using modular and virtual manufacturing technology, the product has a structure and motion characteristics similar to conventional beam pumping units.
2. The reducer adopts symmetrical split-type involute or double-circular-arc herringbone gear transmission, with good sealing, low noise, smooth operation, and reliable durability.
3. The crank is designed with a phase angle to reduce the maximum torque peak of the reducer. By increasing the polar angle, dynamic performance is improved, motor power is reduced, and significant energy-saving effects are achieved.
4. The overall machine structure is optimized, with a high degree of standardization, generalization, and serialization of components. It is easy to operate, maintain, and has a long service life.
