***章填料式密封裝置：（盤根）一、結(jié)構(gòu)：主要由：軸套、填料涵、填料、水封等組成。1、軸套：是用來保護(hù)軸的，防止液體對(duì)軸的腐蝕和使軸不直接與填料產(chǎn)生摩擦。2、填料涵和填料：（盤根箱與盤根）起著把外部與泵殼內(nèi)部隔斷的作用，以減少泄漏量。3、水封：是把水封環(huán)（初191頁(yè)）加在調(diào)料涵內(nèi)，并對(duì)正外接水封管，工作時(shí)水封環(huán)四周的小孔和凹槽處形成水環(huán)，從而阻止空氣漏入泵內(nèi)。還可以起到潤(rùn)滑和冷卻填料和軸套的作用，防止填料和軸套的大量磨損。二、泄漏的處理：1、工作過程：要想減少泄漏量首先應(yīng)先將填料以正確的方式安裝好。1）首先應(yīng)將填料涵內(nèi)徹底清理干凈，并檢查軸套與填料涵的外表面是否完好，有無明顯的磨損情況。2）盤根的規(guī)格應(yīng)按規(guī)定選用，性能應(yīng)與所輸液體相適應(yīng)，尺寸大小應(yīng)符合要求。過細(xì)將泄漏。3）切盤根時(shí)刀口要鋒利，接口要切成30o～45o的斜角，切面應(yīng)平整。切好的盤根裝在填料涵內(nèi)之后必須是一個(gè)整圓，不能短缺，也不能超長(zhǎng)。4）盤根裝入填料涵后，相鄰兩圈接口要錯(cuò)開90o。如果是裝有水冷卻結(jié)構(gòu)的，要注意使盤根錯(cuò)開填料涵的冷卻水進(jìn)口，并把水封環(huán)的環(huán)行室正好對(duì)正進(jìn)水口。5）裝上**末一圈盤根后，將填料壓蓋裝好并均勻擰緊。廣州神通博格曼機(jī)械密封103102神通博格曼機(jī)械密封。</p><div
