【摘要】：注水管內壁切削除垢技術是一種機械除垢的加工方式,能有效地增大工作內徑,提高注水壓力,從而提高注水效率。相對于化學除垢以及高壓水射流除垢,機械除垢更加環(huán)保、操作更加方便,除垢效果也更加顯著,因此研究注水管內壁切削除垢的應用具有重要意義。本論文在分析注水管內壁垢物主要成分的基礎上,對垢物的切削機理進行了研究,從而得出垢物切削機理模型。根據(jù)垢物切削機理模型的特點,對注水管內壁切削除垢刀具進行了設計和制造,并對所設計的刀具進行有限元結構靜力分析,計算了其強度、剛度,確定了刀具結構參數(shù)。在垢物切削機理模型的基礎上,對注水管結垢試件進行了切削除垢試驗,分析了轉速和進給量對切削力、切削效率的影響,獲得了切削除垢合理的動力和運動參數(shù),為除垢裝置的動力和運動設計提供了依據(jù)。本課題旨在對注水管內壁切削除垢技術進行試驗和理論研究,通過對脆性材料切削機理的研究及設計合適的切削裝置,進一步提高注水管除垢的效率和可靠性,這對于注水管內壁除垢技術實踐應用具有現(xiàn)實指導意義。
[Abstract]:The technology of cutting and removing scale in the inner wall of water injection pipe is a kind of machining method of mechanical scale removal, which can effectively increase the working inner diameter and water injection pressure, thus improving the efficiency of water injection. Compared with chemical scale removal and high pressure water jet scale removal, mechanical scale removal is more environmentally friendly, easier to operate and more effective. Therefore, it is of great significance to study the application of cutting scale removal in the inner wall of water injection pipe. Based on the analysis of the main components of the dirt in the inner wall of the water injection pipe, the cutting mechanism of the scale is studied in this paper, and the cutting mechanism model of the scale is obtained. According to the characteristics of the scaling cutting mechanism model, the scale removal tool for cutting the inner wall of water injection pipe is designed and manufactured. The finite element structure static analysis of the designed tool is carried out, the strength and stiffness of the tool are calculated, and the structural parameters of the tool are determined. Based on the model of scale cutting mechanism, the scale removal test was carried out on the scale forming specimen of water injection pipe. The effects of speed and feed rate on cutting force and cutting efficiency were analyzed, and the reasonable dynamic and motion parameters of cutting scale removal were obtained. It provides the basis for the dynamic and motion design of the scale removal device. The purpose of this subject is to test and study the scale removal technology of water injection pipe's inner wall. Through the research on cutting mechanism of brittle material and the design of suitable cutting device, the efficiency and reliability of scale removal of water injection pipe can be further improved. This is of practical significance for the practical application of scale removal technology in the inner wall of water injection pipe.
