An energy-saving and environment-friendly adjustable pumping unit

Abstract

The invention belongs to the field of petroleum equipment, and specifically discloses an energy-saving and environment-friendly adjustable pumping unit, which includes a lever bracket and an oil pumping motor. A support seat is arranged between the lever bracket and the oil pumping motor. A reducer is installed on the seat. The present invention can adjust the formation of the sucker rod according to the pumping depth, avoid the invalid pumping stroke of the sucker rod, improve the single pumping efficiency of the whole pumping unit, and effectively cool down the reducer during the working process, avoiding long When the reducer on the pumping unit is working at high temperature, the internal bearing is damaged, the service life is reduced, and the use efficiency is reduced. Through the design of three guide belts, the distance between the three guide belts can be adjusted according to the inner diameter of the oil well when the sucker rod is pumping oil. , so that when the sucker rod pumps oil, the guide belt contacts the inner wall of the oil well for guidance, preventing the sucker rod from shifting and causing invalid travel.

Description

Technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to an energy-saving and environmentally-friendly adjustable pumping unit. Background technique [0002] Pumping unit is a kind of machinery and equipment used to extract petroleum, 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 beam pumping unit and beamless pumping unit. [0003] The patent document (CN201711030414.9) discloses a new type of horizontal pumping unit. The pumping unit is equipped with a support system, a power system and a transmission system to avoid the use of walking beams and heavy frames and reduce a large amount of steel consumption. The fixed support frame and the movable support frame are used to support the belt drum device. Through the connection of the crank and the connecting rod, the pumping belt is further connecte...

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
