摘要
灌用泥漿泵被廣泛的應(yīng)用在水庫(kù)大壩、煤礦巷道、隧道灌漿、高速公路邊坡維護(hù)、建筑地基加固等場(chǎng)合,隨著國(guó)民經(jīng)濟(jì)的發(fā)展,此類泥漿泵的需求量也越來(lái)越大。近年來(lái),灌用泥漿泵的研制和發(fā)展也越來(lái)越快,但其也存在著許多的問(wèn)題:一是此類泥漿泵的平均無(wú)故障的工作時(shí)間較短,最多也就幾個(gè)小時(shí);二是重量和體積普遍較大,野外搬運(yùn)不便;三是更換密封件的時(shí)間較長(zhǎng)。針對(duì)以上問(wèn)題的提出,本次設(shè)計(jì)有了具體的解決措施,解決密封件壽命短的問(wèn)題,關(guān)鍵是選擇合適的密封材料和合理的結(jié)構(gòu)形式;為了使泵的整體重量減輕,就要徹底放棄傳統(tǒng)的減速方式,取而代之的是先進(jìn)的減速方式,本此設(shè)計(jì)選用的是行星減速器大傳動(dòng)比降速,并將行星減速器置于大帶輪中,既能夠達(dá)到降速的目的,又能夠減輕泵的總體重量。

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 must completely abandon the traditional slowdown, replaced by advanced slowdown, The design chosen is the large transmission planetary reducer than paved, and under great Dailun planetary reducer, both can be achieved faster purposes, and to reduce the overall weight pump.
Key: sealed pieces planetary reducer pressure flow piston
