API RM Reverse Mark Pumping Unit



　　　Product Description
API RM Reverse Mark Pumping Unit is similar in appearance to conventional pumping unit. It adopts phased crank, and is widely used as energy efficient pumping unit in rod pumping work. Our product accords with API Spec 11E Specifications for Pumping Units and Chinese petroleum industry standard GB/T29021-2012 and other related standards.
Performance and advantage
Modularization and virtual manufacturing technology have been adopted in the process of designing. It is similar in appearance and motion characteristics as conventional pumping unit.
The reducer adopts symmetrical involute gear transmission or double circular arc herringbone gear transmission, with good sealing, low noise, smooth running and reliable durability.
 Phase angle on crank reduces maximum torque peak of gear reducer; increase crank angle between two limit positions to improve dynamic performance, reduce motor power; obvious energy-saving effect.
The structure is optimized; the parts are of high standardization, universalization, and serialization. Operation simple, ease of maintenance and long service life.
