API C Pumping Unit
Performance and advantages:
1. Modularization and virtual manufacturing technology have been adopted in the process of designing. Products structure has been optimized, and the parts are of high standardization, universalization and serialization.
2. Finite-element analysis has been adopted to the key structure to realize stable performance and high reliability.
3. The reducer adopts symmetrical involute gear transmission or double circular arc herringbone gear transmission, with good sealing, low noise, smooth running and reliable durability.
4. The unit has the characteristics of simple operation, easy maintenance and long service life.
