At present, the oil field mining use of beam pumping unit, commonly known as' KeTouJi, mainly the use of simple friction force between the motor pulley and belt drive the machine. Belt skid, turn left, and belt transmission efficiency is low is the world's oil field industry manufacturing has been difficult to break through the technical bottleneck problem. Skid make energy not only into busywork, and once in rain and snow weather, wheeled the water skid, idling condition is more frequent, as a direct result of pumping equipment downtime, sucker to suspend the serious consequences. Zui large belt products is a bright spot in energy conservation and emissions reduction, we are currently in zui conservative data calculation, the use of this new belt to section 3. More than 66%. An amount of power saving pumping unit a year will have more than 10000 degrees, if, at present our country owns more than 20 pumping units, ten thousand units, photoelectric can can save more than 20 degrees each year. Pumping units around the world more than 400, ten thousand, all can use energy saving 50 billion degrees, the pollution gas such as carbon dioxide, sulfur dioxide, nearly 50 million tons.
