Embodiment Construction

[0028] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] see figure 1 , the present invention provides an energy-saving pumping unit, which includes a base support 1, an electric motor 2, a reduction box 3, a crank connecting rod system 4, a beam balance system 5, and a pump 6, and also includes an electric control device 7 and connected thereto The oil pump is filled with a coefficient monitor 16; the motor 2 is a double-stator motor. When the pumping unit is started, the double stators operate simultaneously, and the horsepower is large. When the pumping unit operates normally, the required power is small, and the motor is a single-stator operation , to achieve the purpose of energy saving.

[0030] The electric control device 7 is provided with a microprocessor 8, an energy feedback unit 9, a power module unit 10, a compensation capacitor 12, and a thinning controller 13, wherei...

Abstract

The invention relates to the petroleum machinery field, in particular relates to an energy-saving oil pumping unit. The invention provides an energy-saving oil pumping unit to overcome the problems of high energy consumption and low efficiency found in the prior art. The oil pumping unit comprises a base support, a motor, a gear box, a crank arm connecting rod system, a beam balancing system, an oil pump, an electric control device and an oil pump volumetric coefficient monitor; a microprocessor, an energy feedback unit, a power module unit, a compensation capacitor and an interval pumping controller are arranged in the electric control device. The energy-saving oil pumping unit has the advantages of reducing power by 20%-50%, maximizing the power saving effect, improving the oil pump volumetric coefficient at the same time, reducing the loss of the oil pumping unit and the abrasion between the pumping rod and the oil pipe, adjusting the punching times optionally and reducing the labor intensity of the workers.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery, in particular to an energy-saving pumping unit. Background technique [0002] In recent years, the Chinese government has attached great importance to the development of energy, and has successively issued relevant regulations and policies such as the "Energy Conservation Law of the People's Republic of China", "Medium and Long-term Special Plan for Energy Conservation", "Administrative Measures for Energy Conservation and Utilization of Key Energy Consumption Units" and other relevant regulations and policies for energy utilization and energy conservation. Oilfields have also stepped up their efforts in energy saving and consumption reduction, and electricity bills have become the third largest expenditure after the salaries and material costs of oilfield personnel. [0003] At present, there are nearly 300,000 pumping wells in my country's oil fields, and less than one-thousandth of...
