Abstract

The invention discloses a single-motor bilateral-drive energy-saving chain type pumping unit. The pumping unit is composed of a support portion, a transmission portion and a counter weight adjusting portion. According to the pumping unit, two chains are driven by a single motor, tensioning degrees of the chains are adjusted in real time, the stroke is variable, the time of strokes is adjustable, and dynamic counter weight is achieved.

Description

technical field [0001] The invention relates to an oil pumping unit for oil production in the petroleum industry, in particular to an energy-saving chain pumping unit driven by a single motor on both sides. Background technique [0002] At present, most of the oil extraction machines used in my country's oilfields are beam pumping units with rods. Due to their simple structure, high reliability, and convenient operation and maintenance, they are widely used in China. However, domestic oilfields are currently in the middle and late stages of development. , the water cut in the oilfield is increasing, and conventional pumping units cannot be used for more economical and effective extraction. According to statistics, the operating efficiency of domestic pumping units is generally low, the average efficiency is less than 30%, and the annual power consumption exceeds 10 billion kWh. [0003] In recent years, in accordance with the requirements of oil extraction technology, long-s...
