文档介绍：摘要
灌用泥浆泵被广泛的应用在水库大坝、煤矿巷道、隧道灌浆、高速公路边坡维护、建筑地基加固等场合,随着国民经济的发展,此类泥浆泵的需求量也越来越大。近年来,灌用泥浆泵的研制和发展也越来越快,但其也存在着许多的问题:一是此类泥浆泵的平均无故障的工作时间较短,最多也就几个小时;二是重量和体积普遍较大,野外搬运不便;三是更换密封件的时间较长。针对以上问题的提出,本次设计有了具体的解决措施,解决密封件寿命短的问题,关键是选择合适的密封材料和合理的结构形式;为了使泵的整体重量减轻,就要彻底放弃传统的减速方式,取而代之的是先进的减速方式,本此设计选用的是行星减速器大传动比降速,并将行星减速器置于大带轮中,既能够达到降速的目的,又能够减轻泵的总体重量。

Abstract
Fed sludge pump is widely used in the application of dam reservoirs, coal mine, tunnels filled, length of the highway, construction of foundation reinforced, and so on, with the development of the national economy, the demand of such sludge pump is also growing.
In recent years, fed by sludge pump research and development is growing fast, but there are still the existence of many problems : First, the average no-fault sludge pump shorter working hours, up to several hours; Second, the weight and size generally larger field handling inconvenience; Third is the replacement of sealed pieces over a longer period of time. Responding to the above questions, this design has specific solutions to address the short life of the sealed, the key is to choose suitable materials and sealed reasonable structure; In order to make the overall weight pump, we pletely abandon the traditional slowdown, replaced by advanced slowdown, The design chosen is the large transmission ary reducer than paved, and under great Dailun ary reducer, both can be achieved faster purposes, and to reduce the overall weight pump.
Key: sealed pieces ary reducer pressure flow piston
