在石油化工行業(yè)，離心泵具有性能范圍廣、流量均勻、結(jié)構(gòu)簡單、運(yùn)轉(zhuǎn)可靠和維修方便等諸多優(yōu)點(diǎn)，得到了廣的使用，占裝置泵總量的70～80％。而常見離心泵有單端面密封離心泵、雙端面密封離心泵及屏蔽泵等。那么，在輸送危險(xiǎn)物料時(shí)單端面密封離心泵、雙端面密封離心泵及屏蔽泵那個(gè)安全性更好，相對(duì)那種泵又比較經(jīng)濟(jì)。本文以甲醇裂解制氫裝置甲醇輸送泵為例，針對(duì)這3種類型的離心泵的結(jié)構(gòu)特點(diǎn)和軸封特性進(jìn)行分析和探討。一、案例某石化企業(yè)甲醇裂解制氫裝置，原料由甲醇輸送泵P-3307A/B送到裝置進(jìn)料泵,該甲醇輸送泵工藝技術(shù)參數(shù)如下：表1-1：甲醇輸送泵工藝技術(shù)參數(shù)序號(hào)設(shè)備名稱設(shè)備位號(hào)輸送介質(zhì)流量m3/h揚(yáng)程m溫度℃1甲醇輸送泵P-3307A/B甲醇3010040甲醇的特性：甲醇是一種有機(jī)化合物，密度g/mL，沸點(diǎn)℃。甲醇揮發(fā)度高、無色、易燃易爆、有毒，誤飲5～10毫升能雙目失明，大量飲用會(huì)導(dǎo)致死亡。常用危險(xiǎn)化學(xué)品的分類及標(biāo)志(GB13690-92)將該物質(zhì)劃為第類中閃點(diǎn)易燃液體，濟(jì)南脫硫泵用機(jī)械密封，濟(jì)南脫硫泵用機(jī)械密封。二、各泵的結(jié)構(gòu)特點(diǎn)和軸封特性1、機(jī)械密封概述機(jī)械密封（也稱端面密封）是一種用來解決旋轉(zhuǎn)軸和機(jī)體之間的密封裝置，它是由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面，濟(jì)南脫硫泵用機(jī)械密封，在流體壓力和補(bǔ)償機(jī)構(gòu)彈力的作用及輔助密封的配合下。寶雞脫硫泵用機(jī)械密封泄露。濟(jì)南脫硫泵用機(jī)械密封</p><div

在國產(chǎn)離心泵上得到了***的應(yīng)用。本教材以這兩種國產(chǎn)機(jī)械密封為主，結(jié)合其它結(jié)構(gòu)型式（包括進(jìn)口的密封），就有關(guān)的技術(shù)問題和故障分析。第二節(jié)機(jī)械密封的基本元件密封環(huán)是動(dòng)環(huán)和靜環(huán)的總稱（下同），是構(gòu)成機(jī)械密封**主要的元件。一、密封環(huán)在很大程度上決定了機(jī)械密封的使用性能和壽命，對(duì)它提出了一些要求。1）有足夠的強(qiáng)度和剛度。在工作條件下（如壓力、溫度和滑動(dòng)速度等）不損壞，變形應(yīng)盡量的小，工作條件波動(dòng)時(shí)仍能保持密封性。2）密封端面應(yīng)有足夠的硬度和耐腐蝕性，以保證工作條件下有滿意的使用壽命。3）密封環(huán)應(yīng)有良好的耐熱沖擊能力。為此，要求材料有較高的導(dǎo)熱系數(shù)和較小的線膨脹系數(shù)，承受熱沖擊時(shí)不至于開裂。4）密封環(huán)匹配應(yīng)有較小的摩擦系數(shù)和良好的自潤滑性，密封環(huán)材料與密封流體還要有很好的浸潤性。工作中如發(fā)生短時(shí)間的干摩擦，不損傷密封端面。5）密封環(huán)應(yīng)力求簡單、對(duì)稱并優(yōu)先考慮用整體型結(jié)構(gòu)。也可采用組合式（如鑲裝式）密封環(huán)，盡量避免用密封端面噴涂式結(jié)構(gòu)。6）密封環(huán)要容易加工制造，安裝和維修要方便，價(jià)格要低廉。二、摩擦副匹配要考慮的因素摩擦副一般都選擇一軟一硬的配對(duì)。目前軟環(huán)多選用破一石墨（以下簡稱石墨）。濟(jì)南脫硫泵用機(jī)械密封圖木舒克襄樊五二五泵用機(jī)械密封選型。</p><div

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)式機(jī)械密封傳動(dòng)座和動(dòng)環(huán)的傳動(dòng)方式1）銷釘傳動(dòng)。通過推環(huán)，在推環(huán)和動(dòng)環(huán)之間用銷釘實(shí)現(xiàn)傳動(dòng)（圖35），這種傳動(dòng)方式多用在小彈簧的結(jié)構(gòu)上。2）突耳傳動(dòng)。國內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。在動(dòng)環(huán)外緣制成圓弧槽，而將與此接觸的傳動(dòng)座壓成突耳，使之嵌入動(dòng)環(huán)的槽中，實(shí)現(xiàn)傳動(dòng)（圖13）。這種結(jié)構(gòu)可用于大彈簧，也可用于小彈簧的密封結(jié)構(gòu)。3）并圈彈簧傳動(dòng)。傳動(dòng)座與彈簧以及彈簧和動(dòng)環(huán)之間，完全依靠大彈簧內(nèi)徑的過盈值實(shí)現(xiàn)傳動(dòng)（圖34），當(dāng)然也有旋向的要求。這種結(jié)構(gòu)都用在大彈簧的密封結(jié)構(gòu)上。4）勾圈彈簧傳動(dòng)。為了增加并圈彈簧傳動(dòng)的可靠性，彈簧的兩個(gè)端頭制成彎勾形，分別鉤住傳動(dòng)座和動(dòng)環(huán)（圖36）。5）離合器傳動(dòng)。傳動(dòng)座和動(dòng)環(huán)（或通過推環(huán)）分別制成方形的凸起和缺口，組裝好后凸起插入缺口中實(shí)現(xiàn)傳動(dòng)（圖37）。6）波紋管傳動(dòng)。這種方式是波紋管型密封的特有結(jié)構(gòu)，波紋管兩端分別與傳動(dòng)座和動(dòng)環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定。例如，對(duì)金屬波紋管，則采用焊接；對(duì)于橡膠和四氟波紋管，則采用整體或其他方式聯(lián)接。靜止式機(jī)械密封的動(dòng)環(huán)的旋轉(zhuǎn)靜止式機(jī)械密封的動(dòng)環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。天水水泵用機(jī)械密封選型。河北福斯泵用機(jī)械密封哪家好</p><p
