泵的使用和維護(hù)
首先泵與管道安裝好后，不論是采用水壓、氣壓，泵的進(jìn)出口閥門一定要關(guān)閉，方可進(jìn)行試壓，以防損壞密封件，造成漏油。
1.開機(jī)準(zhǔn)備
(1)清理現(xiàn)場(chǎng)，擰開軸承座螺絲，加入干凈導(dǎo)熱油作潤(rùn)滑油。110KW以上大油泵加注潤(rùn)滑油時(shí)由一孔注入直到另一孔有油溢出為止，在灌注過程中用手撫過聯(lián)軸器，待孔內(nèi)不再有氣體冒出即可擰緊螺孔螺栓。
(2)檢查電機(jī)轉(zhuǎn)向是否與泵旋轉(zhuǎn)方向一致。
(3)用手搬動(dòng)聯(lián)軸器泵應(yīng)轉(zhuǎn)動(dòng)靈活。
(4)開車前應(yīng)使用所輸送的導(dǎo)熱油將泵灌滿，以驅(qū)除泵中空氣，此時(shí)吐出口管道上R的閘閥應(yīng)關(guān)閉。
(5)所輸送的導(dǎo)熱油在開車前要均勻加熱，預(yù)熱是利用被輸送的導(dǎo)熱油不斷通過泵體進(jìn)行的，應(yīng)避免溫度的劇烈波動(dòng)，如有異常情 況，應(yīng)立即停機(jī)檢查。
預(yù)熱標(biāo)準(zhǔn)：泵殼溫度不得低于入口油溫40℃，預(yù)熱速度為50℃/ 小時(shí)，在開車預(yù)熱時(shí)應(yīng)將泵支架上的側(cè)螺釘松開0.3-0.5亳米，預(yù)熱完畢應(yīng)擰緊螺釘。
(6)開車前應(yīng)檢查基礎(chǔ)及螺栓有無松動(dòng)，密封是否正常。
2.開機(jī)
(1)全面檢查各項(xiàng)準(zhǔn)備工作是否已經(jīng)完善。
(2)打開各種儀表的開關(guān)。
(3)接通電源，當(dāng)泵達(dá)到正常轉(zhuǎn)速，且儀表顯示出相當(dāng)壓力后，逐漸打開輸出管路上的閘閥，并調(diào)節(jié)到需要工況。在輸出管路上的閘閥關(guān)閉的情況下，泵連續(xù)工作不能超過3分鐘。
(4)泵初始運(yùn)行期間，把生產(chǎn)流程中的設(shè)備緩緩加熱到100~130℃，并且保持在該溫度下繼續(xù)運(yùn)行，脫水脫氣到導(dǎo)熱油中的水分蒸發(fā)，才把設(shè)備加熱到操作溫度。
(5)在機(jī)組初次投入使用，運(yùn)行于工作狀態(tài)之后（或?qū)嶋H試運(yùn)行 3-4小時(shí)〉，應(yīng)再次停機(jī)檢查兩聯(lián)軸器同軸度是否發(fā)生變化，如有變動(dòng)可仍然按上述機(jī)組的安裝與檢查中的規(guī)定來調(diào)節(jié)聯(lián)軸器同軸度，直到符合要求且泵軸能用手輕松盤動(dòng)時(shí)即可。
(6)開機(jī)過程中，要時(shí)時(shí)注意電動(dòng)機(jī)的功率讀數(shù)及振動(dòng)情況，振動(dòng)值不超過0.6毫米，如有異常應(yīng)停車檢查。
3.維護(hù)
(1)泵軸在前端設(shè)置有填料箱，密封性能較為可靠，同時(shí)在軸承座中設(shè)置有機(jī)械密封和油封裝置，因此大量的泄漏不可能出現(xiàn)，而少量的泄漏可以通過泄漏管口排出接收。在開始運(yùn)行初期有少量泄露是正常的，在經(jīng)過一定時(shí)間密封面磨合后泄漏將會(huì)減少或停止。
(2)輸送介質(zhì)傳到泵蓋和軸承上的熱量，由泵蓋和軸承座的表面散熱，使軸承座的溫度適應(yīng)于軸密封性能的溫度。因此選擇泵的安裝位置時(shí)，要使泵蓋和軸承座的熱量便于擴(kuò)散，不出現(xiàn)任何蓄熱現(xiàn)象。
(3)軸承座中設(shè)置有兩個(gè)球軸承，靠泵葉輪側(cè)的一個(gè)球軸承用所輸送的導(dǎo)熱油潤(rùn)滑，靠聯(lián)軸器側(cè)的一個(gè)球軸承則用高溫潤(rùn)滑脂潤(rùn)滑。
每個(gè)球軸承在運(yùn)行3000小時(shí)之后，必須拆下用柴油清洗干凈后，檢查接觸面是否損壞，如有損壞，必須換新的軸承。
靠葉輪側(cè)的球軸承安裝時(shí)，有防塵蓋的一側(cè)要朝向葉輪專 機(jī)前注入導(dǎo)熱油潤(rùn)滑。
靠聯(lián)軸器側(cè)的球軸承，用復(fù)合鈣基高溫潤(rùn)滑脂(ZFG-4)，該軸承重新安裝時(shí)，有防塵蓋的一側(cè)同樣要朝向葉輪側(cè)安裝，安裝時(shí)充填潤(rùn)滑脂(約1/2球軸承與殼體的空間〉。
在軸承運(yùn)行48小時(shí)后，要用潤(rùn)滑脂槍向軸承蓋上的壓注油杯注入補(bǔ)充潤(rùn)滑脂。
(4)不允許用輸入管上的閘閥調(diào)節(jié)流量，避免產(chǎn)生氣蝕。
(5)泵不宜低于30％設(shè)計(jì)流量下連續(xù)運(yùn)轉(zhuǎn)，如果必須在該條件下運(yùn)轉(zhuǎn)，則應(yīng)在出口裝旁通管，且使流量達(dá)到上述最小值以上。
(6)經(jīng)常檢查地腳螺栓的松動(dòng)情況，泵殼溫度與入口溫度是否一致，出口壓力表的波動(dòng)情況和泵的振動(dòng)情況。
(7)注意泵運(yùn)行有無雜音，如發(fā)現(xiàn)異常狀態(tài)時(shí)，應(yīng)及時(shí)處理。
4.停機(jī)
(1)切斷電源。
(2)將泵內(nèi)液體放空，清洗且應(yīng)定期把葉輪旋轉(zhuǎn)180°以防止軸變形，直至泵體冷卻為止。
泵的拆卸和裝配
1.泵的拆卸順序
(1)放凈泵內(nèi)液體及軸承托架內(nèi)的潤(rùn)滑油。
(2)擰下電機(jī)固定螺栓，將電機(jī)搬離底座，拆下兩半聯(lián)軸器。
(3)拆下泵蓋聯(lián)接，松開軸承座托架螺栓，將泵蓋連同軸承托架和轉(zhuǎn)子部分一起從泵體內(nèi)抽出。
(4)擰下葉輪螺母，拆下葉輪。
(5)擰下泵蓋與軸承座螺栓，拆下泵蓋。

(10)在軸承座內(nèi)壓出靜環(huán)“O”形圈。
2.泵的裝配
泵的裝配順序可按拆卸相反順序進(jìn)行。拆卸后再裝配時(shí)要檢查機(jī)械密封件和各零件是否失效，如有失效損壞現(xiàn)象等發(fā)生，一定要換新的配件，安裝時(shí)務(wù)必小心謹(jǐn)慎，不要敲打，以免損壞零件。
機(jī)組的安裝和檢查
1.泵安裝的好壞對(duì)泵的平穩(wěn)運(yùn)行和使用壽命有很重要的影響，所以安裝工作必須仔細(xì)地進(jìn)行，不得草率行事。
2.泵吸入管的安裝高度、長(zhǎng)度和管徑應(yīng)滿足計(jì)算值，力求簡(jiǎn)短，管道彎頭中心到泵底座頭部距離一般應(yīng)小于1米并有焊接鐵板及支撐，見圖1、圖2、圖3所示。
3.吸入和吐出管路也應(yīng)有管架或支撐，泵不允許承受管路的負(fù)荷。
警告：管道上的熱膨脹所產(chǎn)生的應(yīng)力，如果傳遞到泵機(jī)上，會(huì)造成泵機(jī)變形，損壞聯(lián)軸器和軸承以及泵軸等，所以在靠近泵體時(shí)，一定要進(jìn)行支撐。
4.安裝地點(diǎn)應(yīng)足夠?qū)挸?，以方便檢修工作和散熱良好。
5. 安裝順序：
(1)將機(jī)組放在埋有地腳螺栓的基礎(chǔ)上，在底座與基礎(chǔ)之間放成對(duì)墊，作找正用。
(2)松開聯(lián)軸器，用水平儀分別放在泵軸和底座上，通過調(diào)整楔塊墊使機(jī)組調(diào)整至水平，適當(dāng)擰緊地腳螺栓，以防走動(dòng)。
(3)用混凝土灌注底座和地腳螺栓孔。
(4)待混凝土干固后，檢查底座和地腳螺栓是否有不良或松動(dòng)等現(xiàn)象，檢查合格后應(yīng)擰緊地腳螺栓，并重新檢查泵的水平度。
(5)校正泵軸和電機(jī)軸的同軸度，用驗(yàn)平尺檢驗(yàn)時(shí)在聯(lián)軸器外圓上的圓跳動(dòng)不得超過0.1毫米，兩聯(lián)軸器平面間的間隙應(yīng)保證在2~3 毫米之間，通過驗(yàn)平尺相差90°對(duì)聯(lián)軸器進(jìn)行校驗(yàn)時(shí)另一方向的圓跳動(dòng)也不得超過0.1毫米，調(diào)節(jié)時(shí)一般相對(duì)于泵來調(diào)節(jié)電機(jī)，可用平板墊的墊入方法來調(diào)整聯(lián)軸器的同軸度。
(6)在接好管路及確定原動(dòng)機(jī)轉(zhuǎn)動(dòng)方向后，再接上聯(lián)軸器，并再校核一遍聯(lián)軸器外圓的同軸度。
注意：聯(lián)軸器不同心時(shí)，會(huì)造成聯(lián)軸器及彈性塊磨損過大，也會(huì)導(dǎo)致軸承和軸封的損壞，以及泵軸折斷。同軸度達(dá)不到安裝要求嚴(yán)禁開車。
(7)在安裝過程中為防止雜物落入機(jī)器內(nèi)，應(yīng)將機(jī)組所有孔眼均蓋好。
(8)泵在開啟前應(yīng)對(duì)進(jìn)出管道進(jìn)行清洗，特別是對(duì)于焊接式管道應(yīng)注重處理毛刺和焊渣及氧化皮，在泵的進(jìn)口段需加上過濾器，以防雜物進(jìn)入泵內(nèi)。
Pump usage and maintenance:
Firstly, after the pump and pipeline are installed, whether using water pressure or air pressure, the inlet and outlet valves of the pump must be closed before pressure testing to prevent damage to the sealing parts and oil leakage.
1. Preparation before start-up:
(1) Clean the site, loosen the bearing seat screws, and add clean heat transfer oil as lubricating oil. For oil pumps above 110KW, lubricating oil is injected from one hole until oil overflows from another hole. During the filling process, stroke the coupling with your hａnd until no gas escapes from the hole, then tighten the screw bolt.
(2) Check whether the motor rotation direction is consistent with the pump rotation direction.
(3) Move the coupling pump by hａnd to ensure flexibility.
(4) Before starting, fill the pump with the heat transfer oil to be transported to remove the air in the pump. At this time, the gate valve R on the outlet pipeline should be closed.
(5) The heat transfer oil to be transported should be evenly heated before starting. Preheating is carried out by continuously passing the heat transfer oil to be transported through the pump body, and temperature fluctuations should be avoided. If there is an abnormal situation, stop immediately for inspection.
Preheating standard: The pump casing temperature should not be lower than the inlet oil temperature of 40℃, and the preheating speed should be 50℃/hour. During preheating, loosen the side screws on the pump bracket by 0.3-0.5 mm. After preheating, tighten the screws.
(6) Before starting, check whether the foundation and bolts are loose and whether the sealing is normal.
2. Start-up:
(1) Check whether all preparations have been completed.
(2) Turn on the switches of various instruments.
(3) Turn on the power supply. When the pump reaches normal speed and the instrument displays a corresponding pressure, gradually open the gate valve on the output pipeline and adjust it to the required working condition. The pump cannot work continuously for more than 3 minutes with the gate valve on the output pipeline closed.
(4) During the initial operation of the pump, slowly heat up the equipment in the production process to 100-130℃ and keep it running at this temperature. Dehydration and degassing of water in the heat transfer oil should be completely evaporated before heating the equipment to the operating temperature.
(5) After the unit is put into use and runs in working condition (or actual trial operation for 3-4 hours), stop again to check whether the coaxiality of the two couplings has changed. If there is a change, adjust the coaxiality of the couplings according to the installation and inspection requirements of the unit until it meets the requirements and the pump shaft can be easily rotated by hand.
(6) During start-up, always pay attention to the power reading and vibration of the motor. The vibration value should not exceed 0.6 mm. If there is an abnormal situation, stop for inspection.
3. Maintenance:
(1) The pump shaft is equipped with a stuffing box at the front end, which has reliable sealing performance. At the same time, there are mechanical seal and oil seal devices in the bearing seat. Therefore, a large amount of leakage cannot occur, and a small amount of leakage can be discharged through the leak pipe. A small amount of leakage at the beginning of operation is normal. After a certain period of time, when the sealing surface is worn in, leakage will decrease or stop.
(2) The heat transmitted by the conveyed medium to the pump cover and bearing is dissipated by the surface of the pump cover and bearing seat, so that the temperature of the bearing seat adapts to the temperature of shaft sealing performance. Therefore, when choosing a pump installation position, make sure that heat dissipation from the pump cover and bearing seat is easy and that no heat storage occurs.
(3) Two ball bearings are installed in the bearing seat, with one ball bearing adjacent to the impeller lubricated with heat transfer oil, and another ball bearing adjacent to the coupling lubricated with high-temperature grease.
After each ball bearing has been running for 3000 hours, it must be removed and cleaned with diesel oil to check whether there is any damage to its contact surface. If there is damage, a new bearing must be replaced.
When installing a ball bearing adjacent to an impeller, make sure that one side of its dust cover faces toward the impeller.
