Abstract

The invention relates to a energy-saving method of oil extractor, wherein, the power axle is connected to the motor axle via speed reducer; the best speed reducer is planet gear speed reducer; the input axle of planet gear speed reducer is connected to the drive gear which meshes a intermediate planet gear between the transmission gear ring; and the planet gear is connected to the planet support which is connected to the output axle. The invention arranges a speed reducer between the power axle and the motor axle, to reduce the power of motor, and save energy more than 50%.

Description

technical field [0001] The invention relates to an energy-saving method for an oil pumping unit, which can reduce the power consumption and energy consumption of the oil pumping unit. Background technique [0002] The beam pumping unit is a kind of oil production equipment widely used for a long time, because of its strong adaptability, reliable operation and easy management, it is very popular among users. In practice, the power shaft and the motor shaft are directly connected, so that the motor must use a larger power motor, such as the commonly used 6-type machine and 11-type machine, at least 30KW and 37KW electromagnetic speed-regulating motors are required respectively. , high power, and large power consumption have become a major factor affecting the cost of oil recovery. Contents of the invention [0003] The object of the present invention is to provide an energy-saving method for an oil pumping unit, which has good power-saving and energy-saving effects. [000...
