【摘要】：隨著當(dāng)今社會的蓬勃發(fā)展，能源問題日益突出了，石油需求量也越來越大。螺桿泵作為油田使用最為廣泛的采油設(shè)備，生產(chǎn)廠家的數(shù)量也如雨后春筍般猛增，螺桿泵的種類隨之越來越多。螺桿泵質(zhì)量的優(yōu)劣直接影響油田石油開采，質(zhì)量不達(dá)標(biāo)的螺桿泵使用壽命短、工作效率低、故障頻繁等缺點都會影響石油開采，甚至導(dǎo)致重大事故發(fā)生。螺桿泵產(chǎn)品在出廠前進(jìn)行科學(xué)檢測是避免這些問題發(fā)生最有效的方法。目前國內(nèi)很多螺桿泵生產(chǎn)廠家仍使用傳統(tǒng)人工檢測方式，這種方式無法準(zhǔn)確、全面的反映出螺桿泵性能，因而科學(xué)、智能的螺桿泵檢測方式是必然趨勢。 本螺桿泵檢測控制系統(tǒng)是根據(jù)錦州市鵬宇泵業(yè)有限公司的要求和國家相關(guān)標(biāo)準(zhǔn)設(shè)計的，用于錦州市鵬宇泵業(yè)有限公司產(chǎn)品進(jìn)行科學(xué)、全面檢測。螺桿泵檢測控制系統(tǒng)主要分為上位機(jī)和下位機(jī)兩大部分。下位機(jī)部分是由檢測模塊和控制模塊組成，上位機(jī)部分為數(shù)據(jù)處理模塊組成。檢測模塊用于檢測螺桿泵試驗過程中泵出入口壓力、介質(zhì)流量和溫度、電機(jī)轉(zhuǎn)速等參數(shù)，根據(jù)允許誤差范圍和最大誤差范圍完成了傳感器、數(shù)據(jù)采集等硬件的選取及相關(guān)硬件電路設(shè)計工作；控制模塊主要由高性能數(shù)字信號處理器和變頻器構(gòu)成，用于控制螺桿泵驅(qū)動電機(jī)轉(zhuǎn)速，由于電機(jī)無法建立精確的數(shù)學(xué)模型，因而選取自適應(yīng)模糊PID控制方法結(jié)合空間矢量脈寬調(diào)制原理設(shè)計三相交流電機(jī)轉(zhuǎn)速控制模塊，為了驗證調(diào)速系統(tǒng)設(shè)計的合理性，在MATLAB/SIMULINK中建立仿真模型，得出仿真結(jié)果。并TMS320F2812芯片為核心設(shè)計了電機(jī)調(diào)速系統(tǒng)相關(guān)電路硬件設(shè)計。數(shù)據(jù)處理模塊利用Visual Basic6.0軟件完成登陸界面、系統(tǒng)主控界面、打印界面等設(shè)計，，主控界面功能為對整個試驗系統(tǒng)進(jìn)行實時監(jiān)控、泵工作效率和容積效率計算、試驗數(shù)據(jù)實時顯示，并將試驗數(shù)據(jù)存儲至制定數(shù)據(jù)庫中，為以后螺桿泵新產(chǎn)品研發(fā)提供依據(jù)。打印界面可打印以往所有試驗的數(shù)據(jù)報表，在實際的螺桿泵檢測系統(tǒng)應(yīng)用，完成在轉(zhuǎn)速分別為100r/min和150r/min情況下對螺桿泵檢測工作，并打印了螺桿泵試驗報告數(shù)據(jù)表。
[Abstract]:With the vigorous development of the society today, the energy problem is becoming more and more prominent, and the demand for oil is increasing. As the most widely used oil recovery equipment in oil fields, the number of screw pumps has increased rapidly, and more kinds of screw pumps have been produced. The quality of screw pump has a direct impact on oil production. The shortcomings such as short service life, low working efficiency and frequent faults will affect oil exploitation and even lead to serious accidents when the quality of screw pump is not up to standard. The most effective way to avoid these problems is to carry out scientific inspection of screw pump products before they leave the factory. At present, many domestic manufacturers still use the traditional manual testing method, which can not accurately and comprehensively reflect the performance of the screw pump. Therefore, the scientific and intelligent testing method of the screw pump is an inevitable trend. The screw pump detection and control system is designed according to the requirements of Jinzhou Pengyu pump Industry Co., Ltd and relevant national standards. It is used for scientific and comprehensive testing of the products of Jinzhou Pengyu pump Industry Co., Ltd. Screw pump detection and control system is divided into two parts: upper computer and lower computer. The lower part is composed of the detection module and the control module, and the upper part is the data processing module. The detection module is used to detect the parameters of pump inlet and outlet pressure, medium flow rate and temperature, motor speed and so on during the testing process of screw pump. The sensor is completed according to the allowable error range and the maximum error range. The control module is mainly composed of high performance digital signal processor and frequency converter, which is used to control the rotational speed of the screw pump driven motor, because the motor can not establish accurate mathematical model, the control module is mainly composed of high performance digital signal processor and frequency converter, which is used to control the rotating speed of the motor driven by the screw pump. Therefore, the adaptive fuzzy PID control method combined with the principle of space vector pulse width modulation is selected to design the rotational speed control module of three-phase AC motor. In order to verify the rationality of the design of the speed regulation system, the simulation model is established in MATLAB/SIMULINK, and the simulation results are obtained. And TMS320F2812 chip as the core design of the motor speed regulation system related circuit hardware design. The data processing module uses Visual Basic6.0 software to complete the design of the landing interface, the system main control interface and the print interface. The main control interface function is to monitor the whole test system in real time, calculate the pump working efficiency and volume efficiency, and display the test data in real time. The test data are stored in the database to provide the basis for the future research and development of new products of screw pump. The printed interface can print all the data reports of the previous tests and be applied in the actual screw pump testing system. The testing work of the screw pump is completed under the condition of 100r/min and 150r/min, respectively, and the report data table of the screw pump test is printed.
