2、速发展中获得了极为广泛的应用。离心泵的优点包括：可在多种场合使用、本身的体积小、结构简单、操作方便、流量均匀、不易发生故障、使用寿命长、购买费与操作费用低等。在各个方面都会涉及到离心泵的使用，例如在能源、工业、农业，甚至在当今的军事领域很多都利用了离心泵的基本原理。作为油田化学应用专业的学生，离心泵的知识在我们的许多专业课程中都有涉及到，并且在我们所学的液压课中更是对离心泵的内容有了更详细的介绍。通过老师的指导，对离心泵的基本结构与原理我们有了更进一步的了解。通过查阅各种资料使我对离心泵在各个领域的应用，特别是在化工生产方面的应用有了更深刻的了解。当然事物也不是没有缺点的，虽然离心泵因为所具有
3、的的优点使其得到广泛的应用，然而它的缺点是不可忽视的。因为泵工作时动力要求很大，因而它的震动幅度也很大，所以在工作期间出现很多的问题和故障，因此在我们充分的利用离心泵的优点致力于发展国民经济的时候不要忘记解决离心泵所存在的问题，只有这样才能提高离心泵的工作效率!关键词：关键词：基本结构；原理；应用；故障；排除克拉玛依职业技术学院毕业设计（论文）- I -The Subject of Undergraduate Graduation Project (Thesis) of DUTAbstractThe main function of the pump is to raise the liqui
