“泵的品質(zhì)取決于其軸封”泵應(yīng)用成功與否，在很大程度上要取決于是否選擇和使用了適當(dāng)?shù)牧黧w密封裝置。正像我們所知道的，沒(méi)有哪一種泵既可以適用于各種流體和應(yīng)用，同時(shí)又能滿足不同的市場(chǎng)需求和法律規(guī)定。對(duì)流體密封裝置來(lái)說(shuō)，情況也是如此。從泵制造商當(dāng)前有大量的軸封配置（包括機(jī)械式和壓蓋式）可供選擇就可以清楚地看出這一點(diǎn)。在阿法拉伐離心泵、液環(huán)泵和凸輪轉(zhuǎn)子泵中使用的軸封裝置包括：?機(jī)械密封。-單端式，外裝。-單端式，內(nèi)裝。-單端式，外部注水沖洗。-單端式，內(nèi)裝，用于產(chǎn)品循環(huán)或外部注水沖洗。-雙端式，與內(nèi)部密封“背靠背”外裝，用于注水沖洗。離心泵和液環(huán)泵只有1個(gè)軸封，而凸輪轉(zhuǎn)子泵則至少使用2個(gè)軸封（一根軸一個(gè)）。通常而言，所有軸封都處于壓力之下。從泵送流體到密封然后再到空氣存在著一個(gè)壓力梯度。但單端式內(nèi)裝密封或雙端式密封則屬于例外。在這些密封中，產(chǎn)品循環(huán)（*指單端式內(nèi)裝密封）壓力或注水沖洗壓力大于泵壓，所以此時(shí)的壓力梯度方向正好顛倒過(guò)來(lái)。機(jī)械密封符合大多數(shù)應(yīng)用的要求，在這些機(jī)械密封中常用的是單端式密封和單端式注水密封。為了同時(shí)滿足工藝上更高的衛(wèi)生要求以及法律要求（尤其是那些與排放有關(guān)的法律）。青島橡膠機(jī)械密封</p><p
