【摘要】：石油作為支撐當今社會發(fā)展的三大能源之一,被稱為現代經濟發(fā)展的血液。我國是一個石油消費大國,同時也是石油生產大國。在我國大多數地面油井采用抽油機采油,其工作效率較低,年耗電達30~40億千瓦時,性能急需提升。抽油機的工作環(huán)境惡劣,設備重運輸成本高,因此如能夠在實驗室條件下模擬抽油機的工作情況,對于研究和改進抽油機的工作性能具有重大意義。本文研究的抽油機電液伺服加載系統(tǒng),結合機械、液壓、計算機和電子技術,設計了一套電液伺服加載系統(tǒng),該系統(tǒng)能夠模擬抽油機的工作情況,有效減少抽油機性能研究的成本和研制周期,具有重要的理論意義和實用價值。本文介紹了抽油機加載系統(tǒng)的發(fā)展歷程以及電液伺服系統(tǒng)的研究現狀,根據抽油機的工作情況和技術要求,采用電液伺服技術設計了雙閉環(huán)控制抽油機電液伺服加載系統(tǒng)。分析了雙伺服閥加載液壓系統(tǒng)功能和完成主要元件參數計算選擇和液壓系統(tǒng)搭建。設計了伺服加載控制系統(tǒng),采用PLC作為下位機、PC作上位機,通過OPC技術實現PLC與PC機通訊。介紹了PID控制算法和模糊自整定PID控制算法,采用LabVIEW軟件編寫模糊PID控制算法,完成了控制系統(tǒng)程序設計和人機交互界面設計。針對抽油機電液伺服加載系統(tǒng)進行了建模,分析了多余力的干擾作用,基于結構不變性原理介紹雙伺服閥控制的優(yōu)點,利用AMESim軟件進行了系統(tǒng)仿真驗證了液壓系統(tǒng)和控制系統(tǒng)的有效性和合理性。對于本設計的關鍵部分搭建模擬試驗平臺進行了試驗研究,試驗結果分析研究表明系統(tǒng)的設計符合預期目標,能夠滿足設計要求。
[Abstract]:As one of the three energy sources supporting the development of modern society, petroleum is called the blood of modern economic development. China is a large oil consumption country, but also a large oil production country. In most surface oil wells in China, pumping unit is used to produce oil, its efficiency is low, the annual power consumption is 30 ~ 4 billion kilowatt-hours, the performance needs to be improved urgently. The working environment of pumping unit is bad and the cost of heavy equipment transportation is high. So it is of great significance to study and improve the working performance of pumping unit if it can simulate the working condition of pumping unit under laboratory conditions. The electro-hydraulic servo loading system of pumping unit studied in this paper, combined with mechanical, hydraulic, computer and electronic technology, has designed a set of electro-hydraulic servo loading system, which can simulate the working condition of pumping unit. It is of great theoretical significance and practical value to effectively reduce the cost and development cycle of pumping unit performance research. This paper introduces the development history of pumping unit loading system and the research status of electro-hydraulic servo system. According to the working situation and technical requirements of pumping unit, a double-closed-loop control electro-hydraulic servo loading system for pumping unit is designed by using electro-hydraulic servo technology. The function of double servo valve loading hydraulic system, the calculation and selection of main component parameters and the construction of hydraulic system are analyzed. The servo loading control system is designed. PLC is used as the lower computer and PC as the upper computer. The communication between PLC and PC is realized by OPC technology. The pid control algorithm and fuzzy self-tuning pid control algorithm are introduced. The software LabVIEW is used to compile the fuzzy pid control algorithm. The control system program design and human-computer interface design are completed. In this paper, the electro-hydraulic servo loading system of pumping unit is modeled, and the interference effect of multiple Yu Li is analyzed. Based on the principle of structural invariance, the advantages of double servo valve control are introduced. The validity and rationality of hydraulic system and control system are verified by system simulation with AMESim software. The experimental results show that the design of the system accords with the expected goal and can meet the design requirements.
