摘 要
建造高层建筑和多层教学楼等大型设施已经是大势所趋。但由于有些大型设施并不是在交通便利的地段因此在建设过程中建筑泥浆的输送将会是最大的问题,为了解决这一决定性问题就有了本次的设计课题。本次设计的P型喷水柱塞泥(灰)浆泵就是用于火电厂等大型建筑单位的远程灰浆输送。这套设备添加了一套喷水系统,在柱塞进入密封体之前通过安装在柱塞四周的喷水环对其进行清洗,使其表面的灰料全被清洗掉,有效地防止了浆液颗粒进入柱塞和密封件间造成颗粒磨损因此大大降低了柱塞的磨损,提高了本类产品的使用寿命并节约了成本。设计过程主要是用机械设计原理设计P型泵内部零部件,合理布局并对零部件进行强度验算,用流体机械基础根据原始参数确定泵的主要参数流量和扬程,并确定泵的排口管和进口管的直径以及配套电机的类型,用机械设计原理及动力学原理,使各执行机构的动作协调,达到预期功效。

Abstract
The construction of high-rise building and multi-layered classroom building, and other major facilities is the trend of the times.However facilities are not at convenient region.So in the process of building construction ,the delivery of the mud will be the biggest problem, in order to solve this decisiveness issue so have this design.The design of the P-type plunger mud water (ash) pump is used for thermal power plant and other constructions, such as the long-range mud transportation. This set of equipment add a set of sprinkler system ,before the plunger enters the sealing throngh the installation of the fountain ring around the plunger to wash the mud on the face of the plunger ,effective in preventing mud particies into the plunger and sealing.so it is greatly reducing the attrition r of plunger and improving the life of the product and saving the cost. The design process used mechanical design principles to design the parts of the P-type pump, Rational distribution and Checked the strength of the parts. According to the original parameters, used fluid mechanical basis to determine the pump’s main parameters flow and lift,determine the diameter of the influent pipe and exports pipe, and determine the type of Matching motor.Used mechanical design principles and kinetic theory to motor coordination the implementing agencies, to achieve the desired effect.
