1、中國(guó)石油大學(xué)（華東）本科畢業(yè)設(shè)計(jì)（論文）中國(guó)石油大學(xué)（華東）畢業(yè)設(shè)計(jì)（論文）抽油機(jī)地面能耗分析學(xué)生姓名：王光輝學(xué)號(hào)：02021736專業(yè)班級(jí)：石油工程02-7班指導(dǎo)教師：張曉軍2006年6月20日2中國(guó)石油大學(xué)（華東）本科畢業(yè)設(shè)計(jì)（論文）抽油機(jī)地面能耗分析摘要本文根據(jù)游梁式抽油機(jī)四連桿機(jī)構(gòu)的幾何關(guān)系和運(yùn)動(dòng)特點(diǎn)，建立了游梁的擺動(dòng)方程，并精確計(jì)算出游梁式抽油機(jī)懸點(diǎn)運(yùn)動(dòng)參數(shù)；考慮抽油機(jī)光桿靜載荷和慣性載荷及運(yùn)動(dòng)機(jī)構(gòu)的重力和慣性情況，建立了抽油機(jī)系統(tǒng)相對(duì)曲柄的等效動(dòng)力學(xué)模型，并求出具有動(dòng)平衡特征的曲柄軸凈扭矩；根據(jù)抽油機(jī)皮帶傳動(dòng)特點(diǎn)和力學(xué)分析，
2、建立了一種簡(jiǎn)便的皮帶傳動(dòng)效率計(jì)算模型，為分析抽油機(jī)瞬時(shí)工作參數(shù)提供了理論支持；重新定義了周期載荷系數(shù)計(jì)算儲(chǔ)電動(dòng)機(jī)額定功率，并以常規(guī)游梁式抽油機(jī)、調(diào)徑變矩式抽油機(jī)為例，編寫計(jì)算機(jī)程序，實(shí)現(xiàn)了重要參數(shù)的計(jì)算，并繪出關(guān)鍵曲線，由此比較得出了節(jié)能抽油機(jī)的優(yōu)點(diǎn)。文中還對(duì)其他節(jié)能抽油機(jī)進(jìn)行了簡(jiǎn)要介紹。關(guān)鍵詞:速度；加速度；扭矩；周期載荷系數(shù)；調(diào)徑變矩式中國(guó)石油大學(xué)（華東）本科畢業(yè)設(shè)計(jì)（論文）英文名稱ABSTRACTInthispaperbasedontheuniquegeometryandmechanicalmovementofbeampumpin
