style="text-align: center;"><img src="/uploads/img1/20230403/642abf30ac8c1.jpg" title="642abf30ac8c1.jpg" alt="1.webp (2).jpg"/></p><p>　　拆開(kāi)機械真空泵的過(guò)程及留意事項如下:</p><p>　　1、堵截電源，拔下電源插頭。該泵如在體系上，應當從設備上取下。</p><p>　　2、擰開(kāi)放油螺栓放油，用手盤(pán)動(dòng)皮帶輪，使泵腔內余油悉數放出。油應搜集好，一般是在機械真空泵底板下放一鐵制油盤(pán)或磁盤(pán)等(通稱(chēng)方盤(pán))搜集，以便于往后蒸餾收回和免于污染環(huán)境。</p><p>　　3、拆下皮帶，卸下皮帶輪、鍵，脫開(kāi)底板，視電機好壞程度(如發(fā)熱、過(guò)臟、有干磨的噪音，振蕩較大等)應予修補或送電工洗油修補。</p><p>　　4、先拆低真空端蓋板(后端蓋板，即遠離泵輪的一端)，拆開(kāi)時(shí)根據不同螺釘運用不同的東西。關(guān)于一般六角螺釘可用呆扳手，內六角螺釘要用內六角扳手，必要時(shí)要運用套筒扳手，這樣不會(huì )損壞螺釘。擰初步蓋板螺釘后，輕啟端蓋板。端蓋板如密合得很緊，則應慢慢設法起開(kāi)。例如，可用銼刀在泵腔與端蓋板合縫處銼一小槽，然后用起子(改錐)插于小槽處用手敲起子把手，亦可用小錘輕敲起子以退出端蓋板，切不行重錘敲打。</p><p>　　5、用橡皮墊圈密封的則取下橡皮墊圈，退出定位銷(xiāo)。</p><p>　　6、取出轉子及旋片。通常在低轉子端而設有兩個(gè)攻了絲的孑匕用絲桿擰入此孑匕便很簡(jiǎn)單地拉出低轉子了。但要留意拉出轉子時(shí)一定要用手捏緊旋片，因旋片受繃簧力較大，一不小自簡(jiǎn)單脫手飛出，掉于地上或碰到硬物，碰壞旋片棱角及外表造成無(wú)端報賡</p><p>　　7、依4、5、6相仿的辦法拆開(kāi)高真空端，拿出高轉子和旋片。此刻，只需用手捏緊旋片和軸即可取出轉子。</p><p>　　8、著(zhù)手拆泵曾經(jīng)，應事前了解清楚待拆修泵的結構特點(diǎn)、各零部件大致屬哪種結構型式。例如，對那些本身歸于組合件的部件，如某些旋片泵的轉子等，則不要拆開(kāi)，可對其外表作恰當的修正調整;如果組合轉子內落入玻璃屑、金屬異物傷了腔體或本身旋片槽已磨損過(guò)多，需修換配件時(shí)，則可拆開(kāi)，但要當心記住其安裝辦法。</p><p>　　9、每拆下一個(gè)部件，都要查看其精度和光潔度以及損壞情況。旋片及轉子兩端的棱角要特別留意查看其有否損壞，并作好記載。關(guān)于業(yè)務(wù)尚不太熟悉的修泵者，則更應逐漸記住各部件、零件的原安裝方位，作好記載，以防重裝時(shí)記不清搞錯。一起，拆下的零部件不行亂放，堆徹，碰傷，丟失。將其放于一個(gè)方磁盤(pán)里最好，也可放于木盒中并清洗干凈，以綢布蓋機械真空泵全拆修叫做大修，對采納了部分拆修措施而未能排除故障的一些真空泵，其真空度仍低、仍有滲漏等現象;或許有些泵有下述現象之一者：如泵產(chǎn)生“卡死”現象，油很臟而且泵內已結了垢，生了銹或用了不恰當的油使機械真空泵內部零部件上結了硬殼(硅油進(jìn)入機械真空泵內，就可能產(chǎn)生這種景象)，旋片有較大的撞擊聲，泵腔內落入異物(金屬屑、玻璃屑、銅屑等)劃傷泵腔，沖突發(fā)熱溫升很厲害(超越70℃)等，均需將機械真空泵全拆開(kāi)進(jìn)行清洗修補。</p><p><br/></p>
