【正文】 1 “ 某某 ”輪主機(jī)缸套異常磨損 原因分析及解決措施 專 業(yè) 輪 機(jī) 工 程 屆 別 學(xué) 號(hào) 姓 名 指導(dǎo)教師 I 原 創(chuàng) 聲 明 本人 鄭重聲明:所呈交的論文“ 輪主機(jī)缸套異常磨損原因分析及解決措施”,是本人在導(dǎo)師 的指導(dǎo)下開展 研究工作所取得的成果。除文中特別加以標(biāo)注和致謝的地方外,論文中不包含任何其他個(gè)人或集體已經(jīng)發(fā)表或撰寫過的研究成果,對(duì)本文的研究做出重要貢獻(xiàn)的個(gè)人和集體均已在文中以明確方式標(biāo)明,本人完全意識(shí)到本聲明的法律后果,尊重知識(shí)產(chǎn)權(quán),并愿為此承擔(dān)一切法律責(zé)任。 論文作者 (簽字 ): 日期: 年 月 日 I 摘 要 磨損是船用柴油機(jī)最常 見的失效模式之一。隨著目前船舶主機(jī)所用的油料越來越低劣使得氣缸套工作條件更加惡劣,缸套磨損尤其是缸套表面的異常磨損的研究尤其重要。 通過認(rèn)識(shí)氣缸套異常磨損的類型氣缸套及與其失效有關(guān)結(jié)構(gòu)的構(gòu)造特點(diǎn)和材料特性,弄清缸套磨損機(jī)理。分析氣缸套異常磨損產(chǎn)生的原因,從設(shè)計(jì),制造,安裝,使用,維修保養(yǎng),檢修等方面著手,探討缸套異常磨損的形成規(guī)律及其危害,提出預(yù)防解決各種磨損故障的方法。 論文的研究課題有利于掌握磨損產(chǎn)生的機(jī)理和規(guī)律,有利于采取積極的預(yù)防措施和修復(fù)工藝。對(duì)柴油機(jī)的設(shè)計(jì)安裝,使用保養(yǎng)有一定的指 導(dǎo)意義,也有益于提高船用柴油機(jī)的壽命和機(jī)械設(shè)備的使用效益。 關(guān)鍵詞 :柴油機(jī),氣缸套,異常磨損 II Abstract Wear is a Marine diesel engine failure mode of one of the most mon. With the current host used more and more oil ship inferior makes the cylinder liner more bad working conditions, cylinder liner wear especially the abnormal wear of cylinder liner on the surface of the study is particularly important. Through the understanding of the cylinder liner wear types of abnormal cylinder and its failure on the structure of the structure characteristics and material properties, making clear of the cylinder liner wear mechanism. Analysis of the cylinder abnormal wear, cause of from the design, manufacturing, installation and use, maintenance, repair, so as to work out, this paper discusses the formation of the abnormal cylinder liner wear law and its harm, puts forward the prevention to solve all wear the method of fault. This research helps to grasp the production mechanism of wear and rule to take active measures to prevent and repair technology. On diesel engine design installation, use maintenance has some significance, are also good for improving Marine diesel engine39。s life and the use benefit of the mechanical equipment.
