摘要 泥浆泵广泛应用于矿山、水利、煤炭钻井、石油等工业部门。它的工作条件极其恶劣，往往在高扬程、大流量的工作环境下输送含有小颗粒的混合浆液，磨损情况十分严重。为了提高泵的耐磨性能，人们将耐磨材料应用于缸套等过流部件上，或者采用特殊的工艺方法对易磨损部位进行处理。这些措施取得了一定的效果，但是所采用的材料价格昂贵，工艺复杂，增加了泥浆泵的制造、使用成本，部分材料韧性不足，耐冲击性较差，不能适应多变的工作环境，而且耐磨性也不是十分的好。因此，选用新材料，新工艺，成为解决问题的重要研究方向。工程陶瓷具有良好的耐磨性能，但是缺乏韧性是陶瓷的致命缺点。 http://www.paper51.com 本设计将柱塞泵与隔膜泵相结合，用油将泥浆与活塞缸隔离开来，使活塞缸远离恶劣的工作环境，从而提高其使用寿命，能以较低成本达到显著改善泥浆泵耐磨性能的目的。同时，在缸套内壁使用工程陶瓷，进一步增加其耐磨性能。 copyright paper51.com 关键词：泥浆泵 油隔离 磨损 使用寿命 缸套 copyright paper51.com Abstract paper51.com Mud Pump widely used in mining, waterconservancy, coal drilling, oil and other industrial sectors. It's an extremelypoor working conditions, often in high-lift, the flow of the work environmentof small particles containing transmission of mixed size, wear is very serious.In order to increase the pump wear resistance, people will wear-resistant materialsused in the flow components such as cylinder, or to use special methods of wearand tear on vulnerable sites for processing. These measures have yielded somesuccess, but the materials used is expensive, complicated process, an increaseof the mud pump manufacture, use cost, lack of toughness of the material, theimpact resistance of the poor, can not adapt to changing work environment, butalso resistance Grinding and is not very good. Therefore, the choice of newmaterials, new technology, a solution to the problem of important researchdirection. Engineering ceramics has a good wear resistance, but the lack oftoughness is the fatal shortcomings of ceramics. http://www.paper51.com
This will be designed piston pump diaphragmpump and the integration of oil will be mud and Pistons to isolate thecylinder, piston-cylinder away from the poor working conditions, thusincreasing its service life, to achieve a lower cost significantly improve themud pump-resistant Mill performance. At the same time, the use of ceramiccylinder wall, and further increase their wear resistance. copyright paper51.com Key words: mud pump Wear Oil isolation Use Life Cylinder 内容来自论文无忧网 www.paper51.com
