Automatic control of pumps in the waste - water recycle system 中水回用系統(tǒng)泵的自動控制
But now in china the management and the control of pump station is still at a low level 目前國內(nèi)大部分的泵站監(jiān)控和管理機(jī)制還處于相對落后的狀況,不能適應(yīng)生產(chǎn)和科技發(fā)展的要求。
Its feature lies in the inverter control of pump , the undisturbed switch of motor and the driver programming 在水泵變頻調(diào)節(jié)、電機(jī)無擾切換和設(shè)備驅(qū)動程序編制等方面有自己的特色。
3 > the power - load matching control of pump and diesel is also investigated in this paper , which includes economic working control and load limit control of diesel 3 、對液壓泵與柴油機(jī)之間的功率匹配控制進(jìn)行了研究,其中包括柴油機(jī)經(jīng)濟(jì)工作點(diǎn)的控制和防止柴油機(jī)過載的全程極限負(fù)荷控制。
There are remarkable energy saving benefits of variable speed control of pump / fan , and it is deemed to be the best , but there is consanguineous relationship between variable speed energy - saving benefits of pump / fan and pipeline characteristics 泵/風(fēng)機(jī)的變速調(diào)節(jié)因有顯著的節(jié)能效益,被認(rèn)為是最好的調(diào)節(jié)方式,但這種方式的節(jié)能效益與管路特性有著密切的關(guān)系。
Apart from these , the paper also proposes several improvements for pump control , which include changeable cut off control that can prevent several kinds of relief loss of hydraulic system , cross sensing control of pump that can enlarge the variable working range and compound control that combine two kinds of valve control method together 此外,還提出了幾種泵控改進(jìn)方案,其中包括可防止多種系統(tǒng)溢流狀態(tài)的可變壓力切斷控制、能增大泵的變量工作范圍的交叉功率傳感控制以及將兩種閥控策略結(jié)合在一起的復(fù)合控制技術(shù)。
The result of long - term operation shows that the computer control system is practical and effective , it can run in the optimal state within a long duration to fully realize data collection and process , remote data transmission and vfvs constant injection control of pumps . it speeds up the automatic procedures of the seawater treatment process , really realizes the unmanned working , decreases the physical intensity to a large extent , improves the management , enhances the management level , avoids equipment wear down as much as possible , makes the seawater treatment efficient and lessens the cost of production 長期的運(yùn)行結(jié)果表明,該計(jì)算機(jī)控制系統(tǒng)的實(shí)施切實(shí)有效,既成功實(shí)現(xiàn)了對被檢測參數(shù)的數(shù)據(jù)采集與處理、遠(yuǎn)傳以及注水泵機(jī)組的變頻調(diào)速恒壓注水控制,又提高了系統(tǒng)的自動化程序,真正實(shí)現(xiàn)了無人值班作業(yè),在很大程度上降低了工作人員的勞動強(qiáng)度,極大的改善了現(xiàn)場的管理狀況,提高了生產(chǎn)管理水平,且有效避免了設(shè)備損耗,提高了水處理效率,降低了生產(chǎn)成本。
Adopted three layers of c / s and b / s mixed mode , utilized chinese windows2000 operating system platform and delphi 6 in the system , oil recovery engineering management information system based on internet / intranet multi _ tier distributed mode was designed and developed . the system was implement the control of pump state and sucker rod fractures information management and issue > report outputs system maintenances the output predicted to recover the oil and so on . . in addition , the project built can be optimized by analytic and terminal users can also know the latest and future dynamic of production . at present , this system already in daqing recover the oil 8 factorie test and run 系統(tǒng)中采用了三層的c s和b / s混合模式,利用中文windows2000操作系統(tǒng)平臺和delphi6 . 0等工具設(shè)計(jì)并開發(fā)了基于internet intranet的采油工程管理信息系統(tǒng)。該系統(tǒng)可實(shí)現(xiàn)泵況控制、抽油桿斷脫控制、信息管理、發(fā)布、報(bào)表輸出、系統(tǒng)維護(hù)、采油產(chǎn)量預(yù)測等功能,并且可以依據(jù)分析結(jié)果優(yōu)化施工方案,能夠讓各個(gè)終端用戶了解最新和未來的生產(chǎn)動態(tài)。目前,此系統(tǒng)已經(jīng)在大慶采油八廠測試運(yùn)行。
However , the control and management of pump station falls behind other country in our country at present . according to the formers " researching , this system adopts supervisory control of pump station based on fuzzy control . be using fuzzy control technique , plc technique and industry automation software in this system 本系統(tǒng)在前人研究基礎(chǔ)上,構(gòu)建了基于模糊控制思想的泵站微機(jī)監(jiān)控系統(tǒng)框架,提出了以模糊控制技術(shù)、 plc技術(shù)和工業(yè)自動化組態(tài)軟件技術(shù)為特色的現(xiàn)代化泵站自動監(jiān)控系統(tǒng)。
