【摘要】：在煤礦企業(yè)開(kāi)采煤礦的過(guò)程中,由于礦井內(nèi)突水、透水易發(fā)生礦井水災(zāi),無(wú)法保證井下正常的生產(chǎn)和安全,井下排水系統(tǒng)擔(dān)負(fù)著煤礦井下安全生產(chǎn)的重任,一直是生產(chǎn)當(dāng)中的重中之重,礦井潛水泵由于其靈活性可在地面進(jìn)行正常工作,解決煤礦企業(yè)礦下施工排水的難題,能有效滿足正常工礦開(kāi)采、礦井下突水以及透水時(shí)能及時(shí)排水的需求。礦用潛水泵運(yùn)行環(huán)境惡劣、運(yùn)轉(zhuǎn)情況復(fù)雜,所以對(duì)于其安全性和可靠性要求極為重要。相比電動(dòng)潛水泵,風(fēng)動(dòng)潛水泵由于采用壓縮空氣作為動(dòng)力源,安全性好,使用成本低,便于攜帶并且應(yīng)用靈活,因此在煤礦井下中小規(guī)模排水作業(yè)時(shí)應(yīng)用較廣。但是由于風(fēng)動(dòng)潛水泵在井下非連續(xù)工作過(guò)程中易出現(xiàn)輕載或空載,其極限轉(zhuǎn)速可高達(dá)12000r/min～16000 r/min,此時(shí)水泵轉(zhuǎn)速過(guò)快,極易造成"飛車"現(xiàn)象,造成渦輪葉片和泵體側(cè)壁破碎,存在極大的安全隱患。為了防止"飛車"現(xiàn)象的發(fā)生,實(shí)現(xiàn)安全可靠、連續(xù)無(wú)人值守的自動(dòng)化排水作業(yè),急需一種自動(dòng)限速風(fēng)動(dòng)潛水泵控制系統(tǒng)。論文研究的重點(diǎn)是:針對(duì)風(fēng)動(dòng)潛水泵輕載或空載運(yùn)行時(shí)的出現(xiàn)的"飛車"現(xiàn)象,設(shè)計(jì)輕載或空載時(shí)自動(dòng)限速"防飛車"風(fēng)動(dòng)潛水泵控制系統(tǒng),提出相關(guān)的基本原理和設(shè)計(jì)相關(guān)的實(shí)驗(yàn)驗(yàn)證方法,并對(duì)氣動(dòng)控制系統(tǒng)進(jìn)行仿真分析,根據(jù)氣動(dòng)控制系統(tǒng)結(jié)構(gòu)圖,在仿真軟件AMESim中搭建氣動(dòng)控制系統(tǒng)的仿真模型,驗(yàn)證自動(dòng)限速系統(tǒng)對(duì)風(fēng)動(dòng)潛水泵的正常工作無(wú)影響,通過(guò)設(shè)計(jì)實(shí)驗(yàn)和工業(yè)實(shí)驗(yàn),實(shí)現(xiàn)風(fēng)動(dòng)潛水泵的自動(dòng)限速,提高了礦井潛水泵監(jiān)控的自動(dòng)化。具體內(nèi)容如下:首先,論文從自動(dòng)限速控制系統(tǒng)的總體設(shè)計(jì)入手,對(duì)氣動(dòng)控制系統(tǒng)、液位控制系統(tǒng)的結(jié)構(gòu)設(shè)計(jì)進(jìn)行了介紹;其次,對(duì)防爆箱體框架的進(jìn)行了設(shè)計(jì)制造,對(duì)電-氣系統(tǒng)元器件進(jìn)行選擇,根據(jù)自動(dòng)限速風(fēng)動(dòng)潛水泵控制系統(tǒng)設(shè)計(jì)了模擬實(shí)驗(yàn),并驗(yàn)證了功能;再次,對(duì)自動(dòng)限速風(fēng)動(dòng)潛水泵控制進(jìn)行工業(yè)實(shí)驗(yàn),對(duì)自動(dòng)限速技術(shù)進(jìn)行調(diào)試和研究,最后,基于AMESim仿真軟件,驗(yàn)證自動(dòng)限速系統(tǒng)對(duì)風(fēng)動(dòng)潛水泵的正常工作無(wú)影響。
[Abstract]:In the process of mining coal mine in coal mine enterprises, due to the water inrush in the mine, the permeable water is easy to occur in the mine flood, which can not guarantee the normal production and safety in the underground, the underground drainage system bears the heavy responsibility of safe production in the underground coal mine. It has always been a top priority in production. Because of its flexibility, the submersible pump can carry out normal work on the ground, solve the problem of drainage under coal mine construction, and can effectively meet the normal mining. Mine water inrush and water permeation can be timely drainage requirements. Mining submersible pump operating environment is bad, operation is complex, so for its safety and reliability requirements are extremely important. Compared with electric submersible pump, With compressed air as power source, pneumatic submersible pump is safe, low cost, easy to carry and flexible in application. Therefore, it is widely used in small and medium scale drainage operation in coal mine. However, because the pneumatic submersible pump is easy to appear light load or no load in the downhole discontinuous working process, its limit speed can be as high as 12000r/min~16000 r / min, and the speed of the pump is too fast. It is easy to cause the phenomenon of "flying car", resulting in the breakage of the side wall of turbine blade and pump body, and there are great safety hidden dangers. In order to prevent the phenomenon of "flying car" from happening, to realize the automatic drainage operation, which is safe and reliable and continuously unattended, An automatic speed limiting pneumatic submersible pump control system is urgently needed. The control system of "anti-flying vehicle" pneumatic submersible pump with automatic speed limit under light load or no-load is designed. The related basic principle and experimental verification method are put forward, and the simulation analysis of pneumatic control system is carried out, according to the structure diagram of pneumatic control system, The simulation model of pneumatic control system is built in the simulation software AMESim to verify that the automatic speed limiting system has no effect on the normal operation of the pneumatic submersible pump. The automatic speed limit of the pneumatic submersible pump is realized by designing experiments and industrial experiments. The automation of mine submersible pump monitoring is improved. The specific contents are as follows: firstly, the paper introduces the structure design of pneumatic control system and liquid level control system from the overall design of automatic speed limiting control system. The explosion-proof box frame is designed and manufactured, the components of electro-pneumatic system are selected, the simulation experiment is designed according to the control system of automatic speed limiting pneumatic submersible pump, and the function is verified. The industrial experiment on the control of automatic speed limiting pneumatic submersible pump is carried out, and the automatic speed limiting technology is debugged and studied. Finally, based on AMESim simulation software, it is verified that the automatic speed limit system has no effect on the normal operation of the pneumatic submersible pump.
