【摘要】:往復(fù)機(jī)械廣泛應(yīng)用工業(yè)、農(nóng)業(yè)、交通運(yùn)輸、國(guó)防以及科學(xué)研究等各個(gè)領(lǐng)域中,其具有結(jié)構(gòu)復(fù)雜,激勵(lì)源多等特點(diǎn),在實(shí)際生產(chǎn)中,一旦發(fā)生故障,不僅會(huì)影響工業(yè)生產(chǎn)過(guò)程,造成巨大損失,還會(huì)帶來(lái)一系列安全問(wèn)題。因此,為了保證機(jī)組安全運(yùn)行,生產(chǎn)企業(yè)需要一套經(jīng)濟(jì)可靠的往復(fù)式壓縮機(jī)故障診斷系統(tǒng)對(duì)壓縮機(jī)故障進(jìn)行早期監(jiān)測(cè)及診斷。 隨著電子技術(shù)和軟件技術(shù)的發(fā)展,虛擬儀器技術(shù)融合計(jì)算機(jī)強(qiáng)大的硬件資源,突破了傳統(tǒng)儀器在數(shù)據(jù)處理、顯示、存儲(chǔ)等方面的限制,大大增強(qiáng)了傳統(tǒng)儀器的功能。利用虛擬儀器技術(shù)開發(fā)機(jī)械設(shè)備狀態(tài)監(jiān)測(cè)與故障診斷系統(tǒng),成為機(jī)械故障診斷領(lǐng)域中的研究熱點(diǎn)。本文介紹了壓縮機(jī)故障診斷技術(shù)和虛擬儀器技術(shù),并總結(jié)了壓縮機(jī)信號(hào)的常用處理方法。隨后利用NI公司的LabVIEW軟件進(jìn)行編程,開發(fā)信號(hào)采集與分析系統(tǒng)。在轉(zhuǎn)子實(shí)驗(yàn)臺(tái)上測(cè)試本系統(tǒng)的穩(wěn)定性與可行性,并將該系統(tǒng)應(yīng)用于往復(fù)式壓縮機(jī)的信號(hào)采集與分析,實(shí)時(shí)地顯示壓縮機(jī)在工作過(guò)程中的狀態(tài)參數(shù)。通過(guò)與標(biāo)準(zhǔn)工作狀態(tài)下示功圖及小波重構(gòu)后的圖形進(jìn)行對(duì)比分析,診斷壓縮機(jī)運(yùn)行過(guò)程中出現(xiàn)的故障。該論文研究成果為往復(fù)式壓縮機(jī)故障診斷儀器的開發(fā)提供了一種新的思路和切實(shí)可行的方案。
[Abstract]:Reciprocating machinery is widely used in many fields such as industry, agriculture, transportation, national defense and scientific research. It will not only affect the industrial production process, cause huge losses, but also bring a series of safety problems. Therefore, in order to ensure the safe operation of the unit. A set of economical and reliable reciprocating compressor fault diagnosis system is needed in the production enterprise. With the development of electronic technology and software technology, virtual instrument technology integrates the powerful hardware resources of computer, breaking through the limitations of traditional instruments in data processing, display, storage and so on. The functions of traditional instruments are greatly enhanced and the condition monitoring and fault diagnosis system of mechanical equipment is developed by using virtual instrument technology. It has become a research hotspot in the field of mechanical fault diagnosis. This paper introduces the compressor fault diagnosis technology and virtual instrument technology. The common processing methods of compressor signal are summarized, and then the programming is carried out by using NI company's LabVIEW software. A signal acquisition and analysis system is developed. The stability and feasibility of the system are tested on the rotor test bench, and the system is applied to the signal acquisition and analysis of reciprocating compressor. The state parameters of the compressor in the working process are displayed in real time. The results are compared with the indicator diagram in the standard working state and the reconstructed graph by wavelet. This paper provides a new train of thought and feasible scheme for the development of reciprocating compressor fault diagnosis instrument.
