【正文】 eam pumping unit has the advantages of simple structure, high reliability, and has been widely applied in the field. Along with the development of the petroleum industry, now, in order to increase the adaptability of the pumping unit, reliability, economy and advanced, improve the efficiency of oil, reduce power consumption, improve the motion characteristics and pumping dynamic characteristics and balance. So the general development trend and pumping unit is large load, and long stroke to flush times, low precision balance, automation, energy saving, intelligent, and high adaptability.Outofphase type beam pumping unit is the most widely used oil pumping unit is an energysaving. It39。最后對(duì)各結(jié)構(gòu)進(jìn)行了應(yīng)力和強(qiáng)度校核。由于計(jì)算工作量大，在手算基礎(chǔ)上采用了計(jì)算機(jī)的 Excel 軟件優(yōu)選了抽油機(jī)的幾何尺寸。本文介紹了異相型游梁式抽油機(jī)工作原理與節(jié)能原理，進(jìn)行了運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)分析計(jì)算、平衡計(jì)算。異相型游梁式抽油機(jī)是油田應(yīng)用最為廣泛的一種節(jié)能型抽油機(jī)。隨著石油工業(yè)的發(fā)展，目前，為了增加抽油機(jī)的適應(yīng)性、可靠性、經(jīng)濟(jì)性和先進(jìn)性，提高抽油效率，減少動(dòng)力消耗，改善抽油機(jī)的運(yùn)動(dòng)特性、動(dòng)力特性與平衡特性。異相型游梁式抽油機(jī)設(shè)計(jì)摘 要抽油設(shè)備中，以游梁式抽油機(jī)最為普遍，數(shù)量也最多。游梁式抽油機(jī)具有機(jī)構(gòu)簡(jiǎn)單、可靠性高等優(yōu)點(diǎn)，因而在油田得到了廣泛應(yīng)用。因此國(guó)內(nèi)外抽油機(jī)的總的發(fā)展趨勢(shì)是向著超大載荷，長(zhǎng)沖程，低沖次，精確平衡，自動(dòng)化，智能化，節(jié)能化，高適應(yīng)性方向發(fā)展。它的設(shè)計(jì)原理與方法對(duì)抽油設(shè)備具有通用性。為此，將曲柄回轉(zhuǎn)運(yùn)動(dòng)分成 24 等分，逐點(diǎn)計(jì)算懸點(diǎn)的光桿因數(shù)、扭矩因數(shù)、加速度、載荷值；曲柄扭矩計(jì)算、平衡率計(jì)算及交變載荷系數(shù)計(jì)算等。對(duì)主要部件進(jìn)行了選擇計(jì)算，合理選擇電動(dòng)機(jī)和雙圓弧齒輪減速器，設(shè)計(jì)了窄 V 帶傳動(dòng)裝置。設(shè)計(jì)顯示：如果異相型游梁式抽油機(jī)的幾何尺寸得到優(yōu)化，節(jié)能效果是顯著的。s design principle and method of pumping equipment. The paper introduces the beam pumping unit type outofphase working principle and the energy saving principle, kinematics and dynamics analysis and calculation, the equilibrium calculation. Therefore, will turn into twentyfour equal crank movement point, the calculation of strength factor, hanging point torque factor, acceleration, load value, Crank torque calculation, balance ratio and alternating load coefficient calculation, etc. Due to the big workload is calculated based on the hand, using puters Excel the optimum geometric dimension of the pumping unit.The choice of main ponents, reasonable choice of double circulararc gear reducer motors and narrow, design the V belt transmission device. Finally the stress on the structure and intensity.Design shows that: if outofphase type beam pumping unit, the optimized geometry size energysaving effect is remarkable.Keywords: Outofphase type unit, torque factor, hanging point load, torque目錄前 言 ................................................................11 概述 ................................................................3 國(guó)內(nèi)外抽油機(jī)技術(shù)發(fā)展概況 ........................................3 抽油機(jī)的類型與結(jié)構(gòu)及主要參數(shù) ....................................3 抽油機(jī)的類型 ................................................3 抽油機(jī)的結(jié)構(gòu) ................................................4 游梁式抽油機(jī)主要參數(shù) ........................................7 近幾年抽油機(jī)的研究重點(diǎn)及研究中應(yīng)重視的問(wèn)題 ......................7 抽油機(jī)的研究重點(diǎn) ............................................7 抽油機(jī)研究中應(yīng)該重視的問(wèn)題 .................................10 異相型游梁式抽油機(jī)特、點(diǎn)工作原理與節(jié)能原理 .....................11 異相型游梁式抽油機(jī)特點(diǎn) .....................................11 工作原理 ...................................................11 節(jié)能原理 ...................................................112 設(shè)計(jì)數(shù) 據(jù) ...........................................................13 設(shè)計(jì)數(shù)據(jù) .......................................................13 抽油機(jī)幾何 結(jié)構(gòu)尺寸 .............................................13 抽油機(jī)模型示功圖: ..............................................133 設(shè)計(jì)與 計(jì)算 .........................................................17 異相型游梁式抽油機(jī)幾何尺寸參數(shù)計(jì)算 .............................17 幾何關(guān)系計(jì)算式 .............................................17 符號(hào)含義 ...................................................17 各個(gè)點(diǎn)參數(shù)計(jì)算 .............................................18 扭矩因數(shù)和光桿位置因數(shù)計(jì)算 .................................21 抽油機(jī)運(yùn)動(dòng)學(xué)計(jì)算 ...............................................23 光桿（懸點(diǎn)）加速度計(jì)算式 ...................................23 加速 度計(jì)算 .................................................23 加速度曲線 .................................................24 抽油機(jī)動(dòng)力學(xué)計(jì)算 ...............................................24 懸點(diǎn)載荷計(jì)算式 .............................................24 減速器扭矩計(jì)算 .............................................26 曲柄軸凈扭矩曲線 ...........................................27 平衡率 P?、交變載荷系數(shù) CLF 的計(jì) 算 ..........................27 傳動(dòng)系統(tǒng)設(shè)計(jì) ...................................................27 電動(dòng)機(jī)的計(jì)算與選擇 .........................................27 計(jì)算傳動(dòng)比及減速器的選擇 ...................................29 傳動(dòng)裝置的運(yùn)動(dòng)和動(dòng)力參 數(shù)的計(jì)算及窄 V 帶選 擇 .................314 抽油機(jī)的各部件的強(qiáng)度計(jì)算與校核 ....................................36 連桿的應(yīng)力分析與強(qiáng)度校核 .......................................36 游梁的應(yīng)力分析及強(qiáng)度校核 .......................................38 滾動(dòng)軸承的選擇和壽命計(jì)算 .......................................40 選取軸承并計(jì)算軸承支反力 ...................................40 計(jì)算當(dāng)量載荷 ...............................................41 計(jì)算軸承壽命 ...............................................425 結(jié)論 .......
