Horizontal planet gear ring walking beam pumping unit

Abstract

The invention discloses a horizontal planet gear ring walking beam pumping unit. The horizontal planet gear ring walking beam pumping unit is composed of an oil pumping system, a walking beam system, a balancing system, a machine frame system, an inner gear ring reversing system, a motor, a transmission system, a braking system and the like. The motor transfers movement and power to the inner gear ring reversing system through the transmission system. One-way rotational movement is converted into reciprocating rectilinear movement. A rack on the inner gear ring reversing system drives a big gear ring of a walking beam to do reciprocating rotation along a mandrel of the walking beam. A horse head of the walking beam and a steel rope are used for driving the oil pumping system to move, and then oil pumping is achieved in an oil field. The horizontal planet gear ring beam-pumping unit has the advantages that the reliability of the walking beam pumping unit is high, and the steel rope is not prone to damage and also has the advantages of a walking-beam-free oil pumping unit which is efficient, capable of saving energy, long in stroke, large in displacement, high in load, stable and reliable in reversing and the like, thereby being applicable to conventional well oil pumping, deep well oil pumping, extradeep well oil pumping, marine oil pumping and the like.

Description

technical field [0001] The invention relates to an oil field mechanical pumping equipment, in particular to a horizontal planetary gear ring beam pumping unit. Background technique [0002] At present, the beam pumping unit widely used at home and abroad is still the beam pumping unit. The traditional beam pumping unit has the advantages of simple structure, high reliability, and small rope wear, but it also has high energy consumption and low efficiency. And other shortcomings, and the stroke is becoming more and more difficult to meet the market's demand for long strokes. Beamless pumping units have attracted widespread attention due to their advantages of high efficiency and low energy consumption, but the disadvantages of large rope wear and low reliability fundamentally hinder the wide application of beamless pumping units. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned technologies, the present invention proposes a ho...
