摘 要:本次畢業(yè)設(shè)計(jì)的題目是：油井刮蠟裝置設(shè)計(jì)。此設(shè)計(jì)是針對于自噴井構(gòu)思的一個(gè)機(jī)械自動刮蠟裝置。刮蠟裝置由地面提升絞車、井口防噴管、井內(nèi)刮蠟器、井內(nèi)加重件和程序控制等組成。由程序控制地面提升絞車的正反轉(zhuǎn)，由鋼絲牽引著油管內(nèi)的刮蠟器作上下往復(fù)運(yùn)動，將油管內(nèi)壁結(jié)的蠟刮掉。用戶只需設(shè)定刮蠟時(shí)間和刮蠟次數(shù)，就可利用該裝置實(shí)現(xiàn)自動刮蠟。首先通過所學(xué)內(nèi)容結(jié)合查找資料設(shè)想可行性方案，在進(jìn)行分析，方案對比，選材，零件結(jié)構(gòu)的設(shè)計(jì)，主要零件校核，以保證設(shè)計(jì)合理實(shí)用。此設(shè)計(jì)中地面提升絞車的設(shè)計(jì)最為復(fù)雜，是主要設(shè)計(jì)部分，其中零件多，因此對其進(jìn)行了仔細(xì)的分析。最后設(shè)計(jì)出滿足課題要求的一種機(jī)械自動刮蠟裝置。 關(guān)鍵詞：刮蠟器 絞車 防噴管 防噴盒
Abstract:The topic of this graduation design is: oil well paraffin device design. This design is for flowing well conceived a mechanical automatic scraping wax device. Paraffin device by ground hoist, wellhead lubricator, borehole scraper, borehole aggravating piece and process control, etc. By program control ground hoist positive &negative, by wire pulling scraper for reciprocating movement up and down within the tubing, the junction of tubing inwall proves the scrape wax. Users only need to set the time and the number of paraffin wax, to use the device automatically scraping wax. First information via the learned information combined with the feasibility plan, in the analysis, scheme comparison, select material, parts structure design, main parts, to ensure that the design is reasonable and practical. Ground in the design of the hoist in the design of the most complex, is the main part design, including parts, more so on the careful analysis. Final design could satisfy the requirement of subject a scraping wax mechanical automatic device. Keywords: wax scraper；winch；lubricator；swab lubricator |
