摘要
泵是应用非常广泛的通用机械，可以说是液体流动之处，几乎都有泵在工作。而且，随着科学技术的发展，泵的应用领域正在迅速扩大，根据国家统计，泵的耗电量都约占全国总发电量的1/5,可见泵是当然的耗能大户。因而,提高泵技术水平对节约能耗具有重要意义。 6SHZ—60型水泵是清水泵,在设计问题上,从电机的选择计算、轴的选择计算、叶轮的尺寸以及水泵的外形尺寸的确定,基本上解决了泵的大体结构,在其它部件中,连接法兰、叶轮螺母等都是根据具体位置来计算设计的。传动中的轴、键、泵盖都要经过必需的校核,使它的强度和寿命达到设计要求。

Abstract
Pump is the most widely used general machinery,it can be said that any liquid flows,almost all of the pumps work,With the development of science and technology, pumping application areas are expanding rapidly,According to national statistics.Pump power consumption accounted for a fifth of the country,we can see that the pump is only natural consumption market.Pump technology will increase the level of energy conservation has a very important significance.6SHZ-60 is a water pump,the design issues,from motor choices,the choices of axis,the size of impeller pumps dimensions identification,
Largely determine the general structure pump. In other parts, the connecting flanges, Impeller nuts,etc.Are based on the specific location to calculate design.The drive shaft,bond,
Pumps are to be built after the necessary verification,so that their strength and life to the design requirements.

前言
毕业设计是对学生在毕业前所进行的一次综合能力的训练,是为给社会培养出合格的工程技术人员必须走过的重要环节。通过这次的毕业设计可以充分提高我们在以前所学的零散的理论知识的基础上结合起来综合的分析问题、解决问题的能力,这对我们上了岗位有很大的帮助。
我们这次的设计任务是6SHZ—60型的直联式双吸离心泵的基础的设计,是一次专题性的设计,虽然与四年所学知识有一定的偏距,但是为了能把这次的设计搞好,在赵老师的指导下,我们在设计前努力查阅有关资料,做了必要的准备,我们边设计边查阅资料,给设计奠定了一定的基础,这对我们的设计有很大的帮助。
这次设计集中于画图和水泵各部件的设计计算,我们先把指导老师所给的资料中的图纸吃透,独立分析问题,相互探讨并且解决问题,充分体现了我们独立解决问题的能力。
我们应该从现在做起学好扎实的基础知识,不断丰富自己的专业知识和实际操作能力, 这次设计，赵老师对我们进行了精心的指导，阳泉市水泵厂给了大力的支持并提供了有关资料，在此表示感谢，由于我们能力有限，在设计中难免有错误和不足之处。在此，请各位老师给于评定并提出建议。
