ROTAFLEX belt pumping unit

The ROTAFLEX Belt Pumping Unit was manufactured by our company in 1992 through the introduction of American Weatherford Company patented technology. Our company is the only manufacturer of ROTAFLEX belt pumping units in the world. The ROTAFLEX Belt Pumping Unit is a long stroke and low stroke purely mechanicaltransmission pumping unit with international leading level. It is easy to operate, easy to maintain, safe to use and its reliable mechanical performance makes this pumping unit the most widely used beamless pumping unit. It can not only carry out deep pumping, but also carry out large displacement liquid extraction and is especially suitable for heavy oil well production. There are no exposed moving parts, the pit spacing requirement is small, and the minimum pit spacing can reach 2m. Its comprehensive support process and continuous technical update can continuously meet the needs of oil wells under various working conditions. Its features of high efficiency, safety, reliability and energy saving bring good economic benefits to users.

The main advantage

1. Long stroke, low stroke frequency: long stroke makes the overall pump coefficient high, high system efficiency, low stroke frequency can effectively reduce downhole equipment fatigue and wear, extend oil well repair-free period, and reduce operating costs;

2. Purely mechanical transmission, stable reversal, large load, long service life, heavy load and wide belt transmission power, and its elastic buffer can reduce the impact of reversal, so that downhole equipment runs smoothly;

3. Low required torque: Since the moment arm is only 0.31-0.43m, the torque requirement is greatly reduced, and it is equipped with a small power motor and small torque reduction box, which can save energy by 10-40% compared with conventional beam machines;

4. Optimized structural design: the disc brake system ensures safety, the overall displacement works, the folding structure is convenient for installation and transportation, the moving parts of the whole machine are equipped with safety guards and guardrails, which are safe and convenient for operation and maintenance;

5. Adopt gravity symmetrical balance, pure mechanical balance, convenient and simple balance adjustment;

6. High reliability, no need for frequent maintenance: Wear resistant bearings, long life belts and high strength chains are used to ensure the high reliability of the whole machine. No need for frequent maintenance;

7. Perfect oil production control system, which can extract liquid with big pump or deep pump with small pump.
