摘要
在當(dāng)今的生產(chǎn)技術(shù)領(lǐng)域內(nèi)，廣泛應(yīng)用著乳化液泵，它與乳化液箱組成乳化液泵站，是井下綜合采煤工作面支護(hù)設(shè)備的動(dòng)力源泉，煤礦井下支護(hù)作業(yè)“外注式單體液壓支柱”及“液壓支架”的專用小型推移式注液設(shè)備。該泵具有體積小、重量輕、操作簡便、移動(dòng)靈活、工作平穩(wěn)可靠和高效節(jié)能安全的特點(diǎn)，尤其空間狹小的坑道口，掘進(jìn)頭，低煤層等地段，更是一般大型泵站無法替代的產(chǎn)品。此次設(shè)計(jì)乳化液泵主要是因?yàn)樗诿旱V工業(yè)上有主要的應(yīng)用。
在此次設(shè)計(jì)中，首先選用往復(fù)泵采用了對比的方法進(jìn)行總體方案的設(shè)計(jì)，確定泵的型式，選用曲軸連桿機(jī)構(gòu)為傳動(dòng)方式的結(jié)構(gòu)型式，將曲線運(yùn)動(dòng)轉(zhuǎn)變?yōu)橹本€運(yùn)動(dòng)。總體方案確定以后通過液力計(jì)算對液力端型式進(jìn)行選擇，根據(jù)流體力學(xué)及流體機(jī)械對傳動(dòng)端的結(jié)構(gòu)型式進(jìn)行選擇。選出電機(jī)的型號(hào)考慮到給定的設(shè)計(jì)參數(shù)通過計(jì)算確定泵的主要結(jié)構(gòu)尺寸及參數(shù)。再通過設(shè)計(jì)計(jì)算進(jìn)行液力端主要部件液缸體的設(shè)計(jì)及校核，傳動(dòng)端的主要部件減速機(jī)構(gòu)、曲軸、連桿的設(shè)計(jì)及校核，經(jīng)過校核計(jì)算，最終設(shè)計(jì)合理。

Abstract
In the nowadays field of the technique of the production,extensive use the pump of the emulsification,it integrate with the emulsification liquid make up of emulsification pumping station.It is the bottom of a well synthetical excavate coal working face timbering facility's power headspring,it is also the appropriative minitype process injecting liquid equipment which uses coal mine bottom of a well timbering work “ in the manner of qutside injecting monocase hydraulic pressure underpinning” and “hydraulic pressure bracket”.The pump have many traits eg: small volume、light weight、manipulate simple and convenient、moving agility 、work placidity and credibility、 high efficiency、 saving energy sources , safety and so on.Especially in narrowness roomage's sap ostium、 grub entrance、low coal seam region and so on,it is also the bigness pumping station cannot instead. In this about design the pump of the emulsification,the importance of the reason is that it has extensive use at the coal mine industry.
oncoming design, in the first place, choosing to and fro pump adopting the contrast method go along collectivity project design, confirm the pump' type, chooseing the crank connects pole orgnization's transmission fashion configuration style. Hadorwould the curve sport transform the beeline sport .After the collectivity project design, get across liquid mechanics calculate choosing fluid force end configuration style .Bases hydrodynamics and hydro- mechanism chooseing the transmission end configuration style.Vote in electromotor's type considering the giving design parameter overpass counting confirm the pump mostly configuration dimension and parameter,after the parameter making certain basis power electing electromotor's type.Afterwards passing reckon design for the fluid force end important part liquefy urnbody go along designing and validating ,transmission end's important parts eg: decelerate organization、crank and connects pole's designing and validating, come by the validate accounting ,at last testify the design is feasible.
Key words:The pillar fills flux to and fro pump crank connects pole
