Energy-saving and environment-friendly adjustable oil pumping unit

Abstract

The invention belongs to the field of petroleum equipment, and particularly discloses an energy-saving environment-friendly adjustable oil pumping unit. The unit comprises a lever support and an oil pumping motor. A supporting seat is arranged between the lever support and the oil pumping motor, a tension lever is rotatably mounted at the top of the lever support, and a speed reducer is mounted onthe supporting seat. A sucker rod can be adjusted according to the oil pumping depth, the invalid oil pumping stroke of the sucker rod is avoided, the single-time oil pumping efficiency of the wholeoil pumping unit is improved, the speed reducer is effectively cooled in the working process, and the situations are avoided that when the speed reducer works for a long time at high temperature, an internal bearing of the speed reducer on the oil pumping unit is damaged, the service life is shortened and the use efficiency is reduced. Through the design of three guide belts, the intervals of thethree guide belts can be adjusted according to the inner diameter of an oil well during oil pumping of the sucker rod, therefore the guide belts make contact with the inner wall of the oil well for guiding during oil pumping of the sucker rod, and the situation of invalid stroke caused by deviation of the sucker rod is prevented.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to an energy-saving and environment-friendly adjustable pumping unit. Background technique [0002] Pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine". The pumping unit is the most important lifting equipment in the rod pumping system. According to whether there is a beam, it can be divided into a beam pumping unit and a beam pumping unit without a beam. [0003] The patent document (CN201711030414.9) discloses a new type of horizontal pumping unit. By setting the support system, power system and transmission system, the pumping unit avoids the use of beams and heavy frames, and reduces a large amount of steel consumption. The belt roller device is supported by a fixed support frame and a movable support frame, and the oil pumping belt is further connected through the connection between the crank and the connecting ...

AI Technical Summary

Problems solved by technology

However, when the pumping unit is pumping oil, the sucker rod often has invalid pumping strokes due to the difference in the depth of the oil well, which will cause power loss when pumping oil, and the single pumping efficiency of the whole pumping unit is also low. High, the reducer on the pumping unit is prone to overheating when it is working. In this case, internal bearing damage is likely to occur, the service life is reduced, and the use efficiency is reduced. At the same time, the sucker rod enters the oil well due to the length of the pumping process. There will be an offset within the , resulting in an invalid itinerary
