【摘要】：游梁式抽油機(jī)是一種機(jī)械式采油裝置,它的核心工作機(jī)構(gòu)是曲柄搖桿機(jī)構(gòu),因?yàn)橛瘟后H頭的往復(fù)擺動(dòng)像是在磕頭一般,所以游梁式抽油機(jī)也俗稱(chēng)“磕頭機(jī)”。它是游梁式抽油機(jī)采油系統(tǒng)的地面部分,通過(guò)抽油桿柱與井下部分的抽油泵配合將地下的原油抽汲到地面上來(lái)。目前,游梁式抽油機(jī)占全部機(jī)械采油井的80%以上,但是存在總體效率低的問(wèn)題,我國(guó)是能源消耗大國(guó),隨著能源日益緊缺,完善和發(fā)展游梁式抽油機(jī)節(jié)能研究,對(duì)于抽油機(jī)井節(jié)能降耗、提高經(jīng)濟(jì)效益具有重要意義。本文針對(duì)某型號(hào)異相型曲柄平衡游梁式抽油機(jī)進(jìn)行研究,對(duì)其進(jìn)行了運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)理論分析和虛擬樣機(jī)測(cè)試與有限元仿真分析,并以游梁式抽油機(jī)最大輸入功率最小為目標(biāo)函數(shù)進(jìn)行了優(yōu)化分析。首先根據(jù)異相型游梁式抽油機(jī)的結(jié)構(gòu)和工作原理特點(diǎn),對(duì)異相型游梁式抽油機(jī)的懸點(diǎn)位移、速度、加速度公式進(jìn)行了推導(dǎo),對(duì)游梁式抽油機(jī)的懸點(diǎn)載荷、曲柄扭矩及計(jì)算方法進(jìn)行了分析推導(dǎo),為后文虛擬樣機(jī)測(cè)試與有限元仿真分析做好了理論準(zhǔn)備。其次,使用ADAMS2014虛擬樣機(jī)技術(shù)對(duì)游梁式抽油機(jī)進(jìn)行了運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)精確測(cè)試。對(duì)懸點(diǎn)運(yùn)動(dòng)規(guī)律、懸點(diǎn)沖程長(zhǎng)度進(jìn)行了仿真驗(yàn)證。對(duì)抽油機(jī)各桿件鉸接處進(jìn)行力與力矩測(cè)試,發(fā)現(xiàn)有微小擾動(dòng),經(jīng)過(guò)頻譜分析得出是由于抽油機(jī)工作頻率的2倍頻率所導(dǎo)致的。再次,對(duì)游梁式抽油機(jī)的關(guān)鍵部件進(jìn)行了靜力學(xué)分析、模態(tài)分析和瞬態(tài)動(dòng)力學(xué)分析。通過(guò)對(duì)支架的靜力學(xué)分析,得出應(yīng)力應(yīng)變較小,滿(mǎn)足使用要求。使用ANSYS Workbench軟件對(duì)游梁式抽油機(jī)進(jìn)行了瞬態(tài)動(dòng)力學(xué)仿真,仿真驗(yàn)證了游梁和連桿的等效應(yīng)力和受力變形都滿(mǎn)足使用要求。通過(guò)對(duì)整機(jī)模態(tài)分析,得出游梁和連桿前6階模態(tài)變形相對(duì)較大,所以再對(duì)其分別單獨(dú)做模態(tài)分析,得出本文研究的異相型游梁式抽油機(jī)的工作頻率遠(yuǎn)離固有頻率,不會(huì)發(fā)生共振。最后,根據(jù)游梁式抽油機(jī)機(jī)構(gòu)尺寸的優(yōu)化設(shè)計(jì)基本原則,選取以游梁式抽油機(jī)的核心機(jī)構(gòu)曲柄搖桿機(jī)構(gòu)的最大輸入功率最小化為優(yōu)化目標(biāo),使用ADAMS參數(shù)化建模與優(yōu)化分析功能進(jìn)行優(yōu)化分析,得出游梁式抽油機(jī)曲柄搖桿機(jī)構(gòu)輸入功率的優(yōu)化結(jié)果。
[Abstract]:Beam pumping unit is a kind of mechanical oil recovery device, its core working mechanism is crank rocker mechanism, because the reciprocating swing of the beam donkey head seems to be kowtowing, so the beam pumping unit is also called "kowtowing machine".It is the ground part of the pumping system of beam pumping unit. The underground crude oil is swabbed to the ground through the cooperation between the sucker rod string and the subsurface oil pump.At present, beam pumping units account for more than 80% of all mechanical oil wells, but there is a problem of low overall efficiency. China is a large energy consuming country. With the increasing shortage of energy, the research on energy conservation of beam pumping units has been improved and developed.It is of great significance for pumping wells to save energy and reduce consumption and to improve economic benefits.In this paper, the kinematics and dynamics theory analysis, virtual prototype test and finite element simulation analysis are carried out for a certain type of heterogeneous crank balanced beam pumping unit.The maximum input power of beam pumping unit is taken as the objective function.According to the structure and working principle of the beam pumping unit, the displacement, velocity and acceleration formulas of the suspension point of the beam pumping unit are deduced, and the suspension load of the beam pumping unit is analyzed.The torsion moment of crank and its calculation method are analyzed and deduced, which makes the theoretical preparation for the later virtual prototype test and finite element simulation analysis.Secondly, the kinematics and dynamics of beam pumping unit are measured with ADAMS2014 virtual prototype technology.The movement law and stroke length of suspension point are verified by simulation.The force and torque of the rod hinges of the pumping unit are measured, and the slight disturbance is found. The frequency spectrum analysis shows that it is caused by the double frequency of the pumping unit's working frequency.Thirdly, the key components of beam pumping unit are analyzed by statics, modal analysis and transient dynamics analysis.Through the statics analysis of the support, it is concluded that the stress and strain are relatively small and meet the requirements of application.The transient dynamic simulation of beam pumping unit is carried out by using ANSYS Workbench software. The simulation results show that the equivalent stress and deformation of the walking beam and connecting rod meet the requirements of application.Through the modal analysis of the whole machine, it is found that the first six modes of the traveling beam and the connecting rod are relatively large, so the mode analysis is done separately, and the working frequency of the heterogeneous beam pumping unit studied in this paper is far from the natural frequency.There is no resonance.Finally, according to the basic principle of the optimization design of the beam pumping unit mechanism, the maximum input power minimization of the crank rocker mechanism of the core mechanism of the beam pumping unit is chosen as the optimization objective.Using the function of parametric modeling and optimization analysis of ADAMS, the optimal results of input power of crank rocker mechanism of beam pumping unit are obtained.
