注意事項:

1、操作注意事項

A、泵只允許在規定的參數范圍內運轉;

B、泵不允許在吐出閥門(mén)關(guān)閉或關(guān)到很小開(kāi)度下運轉。否則導致泵發(fā)熱,降低壽命。如果泵是安裝在一個(gè)并聯(lián)系統中,每臺泵都要在特定的參數下運行以保障泵的流量;

C、泵不能關(guān)閉吸入口閥門(mén)運行。否則使泵發(fā)生干轉,導致泵零件損壞;

D、泵輸送介質(zhì)不能含有空氣或者氣體,否則會(huì )使泵的流量和揚程不可能準確的測出,同時(shí)會(huì )產(chǎn)生研磨損壞零件。


2、泵啟動(dòng)前檢查

A、啟動(dòng)泵前,應先盤(pán)動(dòng)轉子,檢查轉子是否靈活;

B、檢查全部螺栓、管路引線(xiàn)的聯(lián)接是否緊固和泵周?chē)陌踩闆r;

C、檢查全部?jì)x表、閥門(mén)及儀器是否正常

D、檢查油環(huán)位置、油位計的油位是否正常;

E、檢查電動(dòng)機的轉向是否與泵的轉向一致。


3、泵的啟動(dòng)

A、打開(kāi)泵的吸入閥和水封水管路的閥;

B、關(guān)閉泵的出口閘閥、壓力表旋塞;用輸送的液體或抽真空系統排除吸入管和泵體內空氣;泵內無(wú)液體時(shí)不允許啟動(dòng),否則會(huì )損壞零件。

C、啟動(dòng)電機,待泵運轉正常后,打開(kāi)壓力表旋塞,慢慢開(kāi)啟泵出口閘閥,觀(guān)察壓力表和開(kāi)關(guān)的指示,按出口壓力表讀數控制泵給定的揚程。


4、泵的運行

A、本型泵靠?jì)绕胶鈾C構平衡軸向力,平衡裝置有平衡液體流出,平衡液體由平衡水管接至吸入段或在平衡室外設置一短管,平衡液體經(jīng)短管流向泵外,為保證泵正常運行,平衡水管絕對不允許堵塞;

B、本型泵滾動(dòng)軸承均無(wú)冷卻裝置,軸承溫升變化反映了泵的裝配質(zhì)量,軸承溫升不得高于環(huán)境溫度35攝氏度,最高溫度不應高于75攝氏度;

C、本型泵轉子在運行中存在一定的軸向游動(dòng),應保證電機和水泵兩聯(lián)軸器端面間的間隙值;

D、泵在運行期間每隔一定的時(shí)間應檢查儀表、泵的轉速和葉輪、密封環(huán)、導葉套、平衡盤(pán)、軸套的磨損情況,磨損量過(guò)大時(shí)應及時(shí)更換。此外,監測泵的流量、揚程、溫度及潤滑情況;泵在發(fā)生故障時(shí),應停泵,且參考故障排除表進(jìn)行維修。


5、泵的停機

停機前應先關(guān)壓力表旋塞,慢慢關(guān)閉出口閘閥,待出口閥門(mén)關(guān)閉完畢后再停電機,當泵停穩后在關(guān)閉泵的吸入閥。


6、泵的維修

為了保持泵高效穩定的工作狀態(tài),泵必須經(jīng)常維修,維修的項目和每次維修的間隔時(shí)間取決泵的工作條件和泵的運行狀況。定期檢查泵的性能(如流量、揚程、振動(dòng)等)而且要做記錄,按這些記錄數據去分析泵是否正常工作,是否需要維修或者確定要修的哪一部位。在一般條件下,如果堅持精密的測試、記錄,定期的總結記錄,那么,每隔幾個(gè)月就可以得到泵是否需要維修的可靠資料。除在規定時(shí)間對泵監測外,下面的維護是經(jīng)常的;

A、檢查泵底座、泵、電機是否緊固,如果松動(dòng)會(huì )引起泵的振動(dòng);

B、檢查儀表、引線(xiàn)的狀況,檢查管路是否泄露或松動(dòng),或其他形式的損壞。如果需要應立即檢修;

C、填料壓蓋不能壓的過(guò)緊,否則會(huì )影響填料壽命;

D、軸承潤滑油每工作1000小時(shí)更換一次。

故障處理:

裝配拆卸:

1、泵的拆卸

拆卸時(shí)應嚴格保護零件的制造精度不受損傷:拆卸穿桿的同時(shí)應將各中段用墊墊起,以免各中段止口松動(dòng)下沉將軸壓彎?


注意亊項:

a、將泵殼內的液體放掉:

b、如果軸承部件是稀油潤滑時(shí)應將潤滑油放掉;

c、拆去妨礙拆卸的附屬管路,如平衡管、水封水管等管路和引線(xiàn),


拆卸順序:

泵的拆卸步驟應從拆下吐出側的軸承部件開(kāi)始,其順序大致如下(因泵的結構有所差別.在拆卸過(guò)程中會(huì )略有不同):

a、檸下吐出側軸承壓蓋上的螺栓及吐出段、填料函體、軸承體三個(gè)零件之間的連接螺母卸下軸承部件乙:

b、擰下軸上的圓螺母,依次卸下護套、軸承內圈(軸承)、有孔軸承壓蓋、擋水圈后,卸下填料體(包括填料壓蓋、填料環(huán)和填料等):

c、依次卸下軸上的O型密封圈、軸套、平衡盤(pán)和鍵后,卸下吐出段(包括末級導葉、平衡環(huán)、平衡套等);

d、卸下末級葉輪和鍵后,卸下中段(包括導葉):按同樣方法依次卸下其余各級的葉輪、中段和導葉,直到卸下首級葉輪為止:

e、擰下吸水段與軸承體的連接螺母和軸承壓蓋上的螺栓后,卸下軸承部件甲(在這之前應先將泵聯(lián)軸器卸下);

f、將軸從吸入段中抽出,擰下軸上的鎖緊螺母,依次將軸承內圈、O型密封圈、軸套和擋套等卸下。


至此拆卸工作基本完成,但在上述拆卸過(guò)程中,還有部分零件是相互連接在一起的,一般情況下擰下連接螺栓或螺母后即可卸下。


2、泵的裝配

清洗和檢查:

a、用煤油清洗全部的零件,在空氣中干燥或用布擦干;

b、檢查全部零件的磨損情況,對不能確保正常運轉的零件應更換;

c、檢查泵軸是否有灰塵或生銹,用千分表檢查軸的不宜度(軸的徑向跳動(dòng)值不大于8級精度);

d、當密封間隙超過(guò)推薦值的最大值50%時(shí),應更換密封元件。


泵的裝配順序一般是按拆卸順序反向進(jìn)行;

本型泵裝配質(zhì)量的好壞直接影響泵能否正常運行,并影響泵的使用壽命和性能參數;影響機組的振動(dòng)和噪音。裝配中應注意以下幾點(diǎn):

a、固定部分各零件組合后的同心度靠零件制造精度和裝配質(zhì)量來(lái)保證,應保護零件的加工精度和表面粗糙度、不允許磕碰、劃傷。作密封劑用的二硫化鉬應干凈,緊固用的螺釘、螺栓應受力均勻。

b、葉輪出口流道與導葉進(jìn)口流道的對中性是依各零件的軸向尺寸來(lái)保證。流道對中性的好壞直接影響泵的性能,故泵的尺寸不能隨意調整。

c、泵裝配完畢后,未裝填料前,用手盤(pán)動(dòng)泵轉子,檢查轉子在殼體內旋轉是否靈活、有無(wú)摩擦響聲,軸向竄動(dòng)量是否達到規定要求。

d、上述檢查符合要求后,在泵兩端軸封處加入填料,注意填料環(huán)在填料腔中的位置。


【泵的安裝】

泵的安裝步驟一般包括把泵放在基地上,找水平,調正和聯(lián)接泵的管路等。


1、泵安裝時(shí)需要的設備

泵安裝時(shí)需要下列常規的專(zhuān)用的設備和工具:

a、有負載能力合適而安全的起重設備;

b、每個(gè)地腳螺釘處都必須備有一塊墊鐵或楔鐵,作找平底座用;

c、灌漿的材料必須是不收縮的灌漿料。為了灌漿需要準備一個(gè)木盒,而且需配有漏斗;

d、安裝和拆卸填料,需要一套專(zhuān)用的工具,如帶鉤的夾具等。


2、泵的搬運在搬運泵時(shí)需要注意安全以防事故發(fā)生,搬運時(shí)要注意下列事項:

a、在搬運泵時(shí),起重機的吊鉤應掛在底座下面:也可以用叉式起重機搬運泵,不允許吊在泵的原動(dòng)機的螺栓孔或吊泵的軸承體,更不能在泵軸處起吊;

b、起重負載應均勻平衡,且應注意起重設備的承載能力,起吊時(shí)應小心謹慎,防止泵件的碰撞,特別應避免泵聯(lián)軸器處軸加工配合面的損壞。

c、嚴禁異物或者灰塵在搬運過(guò)程中掉入泵和電動(dòng)機內


3、泵的開(kāi)箱檢查

泵運到使用單位后因開(kāi)箱檢查泵的零件是否丟失,是否在運輸過(guò)程中有損壞,如果出現由于丟失或者順壞時(shí),應立即向運輸部門(mén)或者制造廠(chǎng)聲明。


4、暫時(shí)庫存

如果泵在安裝以前需要庫存一段時(shí)間,泵仍然需要包裝,而且應該放在干燥、防雨、防灰塵的合適的地方上。泵的吐出口和吸入口應覆蓋,以防異物掉入,泵的軸,軸承和其他精加工零件應注意防潮,要應涂保護油層。


5、泵的基礎

a、泵的基礎必須具有足夠的強度,基礎的質(zhì)量應等于機組質(zhì)量的3-5倍,泵的地基應比泵的底座長(cháng)50-70cm,且要留出地腳螺栓孔(為地腳螺栓3-5倍的鋼管直徑);

b、打地基包括如下內容:地基的地腳螺栓孔的定位,灌漿和留出外連接管路位置,然后在其余空間灌漿,地基的表面可是粗糙的,一邊灌漿效果好。

c、地基完全固化后安裝設備。


6、搬放和找水平

a、在底座下面放置鋼的墊鐵和楔鐵或調整墊,一般都放置在地腳螺栓處。如果底座較長(cháng),在兩地腳螺栓中間可放置一塊墊鐵;

b、檢查底座下面的地基,清洗飛塵,油和其他雜物。

c、起重吊鉤吊住底座的四個(gè)角上,把底座吊在地基上方,慢慢地把底座放在每個(gè)螺栓孔的位置上(對地腳螺栓孔的位置)

d、用一個(gè)刀口平尺和機械水平儀放到安裝泵和電機底腳加工平面上,用調整楔鐵或調整墊的厚度來(lái)確定底座在各個(gè)方位上的水平,推薦每100毫米長(cháng)度不平度小于0.25毫米,這時(shí)地腳螺栓的螺母擰到適當程度(不能過(guò)緊),楔鐵或調整墊片應緊固。

e、底座找平,而且和地基配合較緊后才灌漿。


7、底座的灌漿

a、灌漿時(shí),確保做到每個(gè)空間的空氣必須全部排出

b、當灌漿材料固化后,擰緊地腳螺栓的螺母,然后再對灌漿材料油漆防潮

c、灌漿后,進(jìn)行泵和發(fā)動(dòng)機的調正工作


8、設備的調整

設備調整包括角度的調正和中心線(xiàn)位置的調正,至少應在下面三個(gè)時(shí)期檢查設備,進(jìn)行調正。

第一次:泵和底座已經(jīng)把緊,但電動(dòng)機沒(méi)把緊;

第二次:泵和電動(dòng)機已緊固,但吸入和吐出管路法蘭的螺栓沒(méi)緊固;

第三次:在泵運轉24小時(shí)后,再檢查一次,檢查后把泵和電動(dòng)機最后緊固。


9、在調正工作中應注意以下事宜:

a、電機與水泵組合安裝時(shí),應將泵聯(lián)軸器端軸伸向外拉出,再保證泵和電機兩聯(lián)軸器之間的軸向間隙值。

b、泵只能承受自身內力,不能承受任何外力。

c、在調正以前,檢查全部的管線(xiàn),保證它們不對泵座產(chǎn)生作用力和力矩;

d、在調正泵和電動(dòng)機時(shí),墊片應墊在電動(dòng)機的下面。


角調正是保證聯(lián)軸器的兩個(gè)平面的平行度。用一塊千分表去檢查聯(lián)軸器法蘭端面上的四個(gè)點(diǎn),千分表讀為0.02~0.03;檢查其平行度也可以用塞尺,兩聯(lián)軸器平面間的差值(a-b)≤0.06.中心線(xiàn)對中是指泵和電動(dòng)機軸中心線(xiàn)的對正程度。


10、主要管路的聯(lián)接

泵灌漿后且緊固在地基上以后,在不受外力條件下對正且連接泵法蘭和管路的法蘭;這個(gè)對正聯(lián)接不能依靠法蘭螺栓的力。對管路支撐(附加)應避免管路系統的振動(dòng)。應減少管路對泵的外加力。為了防止泵的損壞,在泵管路連接以前,要對管路系統進(jìn)行清洗。


安裝管路,應注意事項:

a、使用管路的規格和長(cháng)度應合適且有足夠的承壓能力;盡量減少管路的轉彎和附件;

b、泵的吸入管路應是短而直。管路直徑應大于或等于泵的吸入口的直徑,泵的吸入管路的彎曲半徑應做成盡量大。


11、附件設備的聯(lián)接

壓力表:在吸入管路和吐出管路上用的壓力表必須是質(zhì)量好,性能合格的儀表。吐出壓力表最好裝配在泵吐出法蘭2倍直徑長(cháng)的距離上,不能裝在彎管和閘閥的旁邊。以防受不穩定流動(dòng)的干擾。

聯(lián)軸器:泵的電動(dòng)機聯(lián)軸器連接以前重新檢查其對中性;檢查電動(dòng)機的轉向是否符合要求,如果電動(dòng)機轉向不符合泵的轉向,必須把電動(dòng)機轉向調正過(guò)來(lái)。

軸封:如果需要,在泵運轉以前,重新調整軸封或重新裝配。
