【摘要】：離心泵是應(yīng)用廣泛且能耗大的旋轉(zhuǎn)機(jī)械。離心泵機(jī)組在運行過程中由于設(shè)計、制造、裝配、使用、維護(hù)等原因往往會導(dǎo)致機(jī)組故障率高、運行效率低等問題。為此,開展離心泵機(jī)組的狀態(tài)監(jiān)測及優(yōu)化運行的研究顯得尤為重要,是機(jī)組安全高效運行的重要保證。 本文首先基于Labwindows/CVI軟件開發(fā)平臺開發(fā)了離心泵狀態(tài)監(jiān)測系統(tǒng),包括硬件設(shè)計和軟件編制。該系統(tǒng)主要包含數(shù)據(jù)采集模塊、性能監(jiān)測模塊及振動監(jiān)測模塊等。其中性能監(jiān)測模塊具有離心泵運行參數(shù)的實時監(jiān)測、數(shù)據(jù)采集與存儲、揚程性能曲線、功率性能曲線及效率曲線的繪制、數(shù)據(jù)及曲線的報表等功能；振動監(jiān)測模塊具有實時采集振動參數(shù)、數(shù)據(jù)存儲、數(shù)據(jù)分析及圖譜顯示等功能,圖譜顯示主要有時域圖、頻譜圖、濾波圖等。通過性能監(jiān)測和振動監(jiān)測兩個模塊實現(xiàn)了對離心泵的在線監(jiān)測。其次,性能監(jiān)測和振動監(jiān)測模塊分別在離心泵實驗臺和轉(zhuǎn)子實驗臺進(jìn)行了試驗測試,驗證了系統(tǒng)的可靠性和穩(wěn)定性。最后,針對離心泵機(jī)組運行效率低的問題,建立了以機(jī)組軸功率為目標(biāo)函數(shù),以壓力、流量、啟停次數(shù)等為約束條件的數(shù)學(xué)模型,并利用遺傳算法對該模型進(jìn)行了優(yōu)化求解。
[Abstract]:Centrifugal pump is a kind of rotating machinery with wide application and high energy consumption. The failure rate of centrifugal pump unit is often high due to the design, manufacture, assembly, use, maintenance and other reasons. Therefore, it is very important to carry out the research on condition monitoring and optimal operation of centrifugal pump units, which is an important guarantee for the safe and efficient operation of centrifugal pump units. First of all, based on Labwindows/CVI software development platform, a centrifugal pump condition monitoring system is developed, including hardware design and software programming. The system mainly includes data acquisition module. Performance monitoring module and vibration monitoring module. The performance monitoring module includes real-time monitoring of centrifugal pump operating parameters, data acquisition and storage, lift performance curve, power performance curve and efficiency curve drawing. Data and curve reporting function; Vibration monitoring module has the functions of real-time acquisition of vibration parameters, data storage, data analysis and spectrum display. Filter diagram. Through the performance monitoring and vibration monitoring two modules to realize the online monitoring of centrifugal pump. Secondly, the performance monitoring and vibration monitoring module in the centrifugal pump test bench and rotor test platform were tested. The reliability and stability of the system are verified. Finally, aiming at the problem of low efficiency of centrifugal pump unit, the paper establishes the objective function of unit shaft power, pressure and flow rate. The mathematical model with the time of starting and stopping is a constraint condition, and the genetic algorithm is used to solve the model optimally.
