Abstract

The invention relates to the technical field of oil recovery machinery, in particular to an oil pumping machine capable of reversing by utilizing an automatic reversing reducer. The oil pumping machine is characterized by comprising a base, a vertical rack, a motor, a hydraulic coupler, the automatic reversing reducer, a chain, a roller, a flexible belt, a weight block and an oil pumping machine connector, wherein the motor and the automatic reversing reducer are connected by virtue of the hydraulic coupler, the oil pumping machine reverses by utilizing the automatic reversing reducer. The hydraulic coupler for realizing soft start and the reducer with an automatic reversing function are adopted for the oil pumping machine provided by the invention, and the machine has the beneficial effects that: firstly, efficiency is high, energy is saved; secondly, operation is stable, technology is advanced; thirdly, a rack is low, stroke is long; and fourthly, transmission accuracy is high, and service life is long.

Description

technical field [0001] The invention relates to the technical field of oil production machinery, in particular to an oil pumping unit which uses an automatic reversing reducer to reversing. Background technique [0002] At present, in the design process of the pumping unit, when the frequency converter is not used for soft start, the calculation is mainly based on the output torque required by the motor alone to lift the counterweight, and the power selection of the motor is generally too large. Such as 6-12, that is, 700A type pumping units generally use 37Kw-6 motors, which have the disadvantages of large equipment investment and large starting current. [0003] At present, there are mainly two reversing methods for pumping units (except beam pumps). One is to use the mechanical reversing method at the output end of the reducer. This reversing mode is bulky and takes up the space of the counterweight reciprocating stroke, thereby causing the height of the whole frame of t...
