Instead of using previous of reducer, we innovate independently a combination of driving system consisting of permanent magnet synchronous motor and drive mechanism; it is more efficient and reliable.
This machine Fill the gaps for beam-pumping unit, it particularly adapted to oil production requirements of heavy-duty pumping well such as long stroke, low frequency of stroke, large-load, high viscosity, mid-high water-cut stage etc. The field of application has extended to more complex working condition as bigger diameter of pump, long and deep well, mud flat and shoals and so on. In addition, the advantage for combination of driving system as following: long stroke, low frequency of stroke, numerical controlling flexible reverse, energy efficient, recessed balancing weight, remote controlling parameters regulation and excellent flood protection performance.
