、起動(dòng)前要把泵和現(xiàn)場(chǎng)清理干凈； 、檢查托架內(nèi)潤(rùn)滑油量是否適量 油量在油位計(jì)中心線 左
右 ，油位計(jì)是否完好； 、未接聯(lián)軸器前檢查原動(dòng)機(jī)的轉(zhuǎn)向，與泵的轉(zhuǎn)向箭頭一致后
從電機(jī)端看，葉輪順時(shí)針旋轉(zhuǎn) ，接好聯(lián)軸器； 、在裝好機(jī)械密封 或填料 和聯(lián)軸器后可輕便地用手轉(zhuǎn)動(dòng)泵軸，

情況下使用，起動(dòng)前應(yīng)用所輸送液將泵灌滿，驅(qū)除泵中的空氣后， 將吐出管的閘閥關(guān)閉； 、起動(dòng)前檢查基礎(chǔ)螺栓有無(wú)松動(dòng)，壓蓋是否歪斜，以及潤(rùn)滑油
和冷卻水的供應(yīng)情況；
、關(guān)閉進(jìn)出口壓力 或真空 表和出水閥門(mén)、 如有旁通管，此時(shí)
也應(yīng)關(guān)閉 起動(dòng)電機(jī) 最好先點(diǎn)動(dòng)、確認(rèn)泵轉(zhuǎn)向正確后，才開(kāi)始正式
運(yùn)行 ，然后打開(kāi)進(jìn)出口壓力 或真空 計(jì)，當(dāng)泵達(dá)到正常轉(zhuǎn)速，且儀
表指出相應(yīng)壓力時(shí)，再慢慢打開(kāi)出水閥門(mén)，調(diào)節(jié)至需要的工況。在
吐出管路關(guān)閉的情況下，泵連續(xù)工作時(shí)間，不能超過(guò) 分鐘； 、起動(dòng)過(guò)程中要時(shí)時(shí)注意原動(dòng)機(jī)的電流讀數(shù)及泵的振動(dòng)情況； 、密封情況：機(jī)械密封應(yīng)無(wú)泄漏、發(fā)熱現(xiàn)象，填料密封應(yīng)呈連
續(xù)滴流狀態(tài)。
、經(jīng)常檢查和電機(jī)的發(fā)熱情況 軸承的溫度不應(yīng)超過(guò) ℃ 及油
位計(jì)油面情況。 一般每運(yùn)行 小時(shí)后，要全部更換潤(rùn)滑油一次 ； 、不能用吸入閥來(lái)調(diào)節(jié)流量，避免產(chǎn)生汽蝕； 、泵不宜在低于 設(shè)計(jì)流量連續(xù)運(yùn)轉(zhuǎn)，如果必須在該條件下
連續(xù)運(yùn)轉(zhuǎn)，則應(yīng)在出口外安裝旁通管，排除多余的流量； 、注意泵運(yùn)轉(zhuǎn)有無(wú)雜音，發(fā)發(fā)現(xiàn)異常狀態(tài)時(shí)，應(yīng)及時(shí)消除或停
車(chē)檢查。
、緩慢關(guān)閉吐出管路閘閥 如果泵在倒灌情況下使用，還要關(guān)
閉吸入管路的閘閥 ，并關(guān)閉各種儀表的開(kāi)關(guān)； 、切斷電源； 、如果密封采用外部件引液時(shí)，還要關(guān)閉外引液閥門(mén)； 、如果環(huán)境溫度低于液體凝固時(shí)，要放凈泵內(nèi)的液體，以防
凍裂； 、如果長(zhǎng)時(shí)間停車(chē)不用，除將泵內(nèi)的腐蝕性液體放凈外，各零
件應(yīng)拆卸清洗干凈，尤其是密封腔，最好是將泵拆下清洗后重新裝
好，除涂油防銹處理和封閉泵進(jìn)、出口外，還應(yīng)定期檢查。

.? 1. Please clean pump and working spor before driving?? 2. Check lubricant oil proper or not (oil surface is about central line 2mm on
oil meter) and oil meter perfect or not??
3. Before connect coupling should check the rotating direction of motor, the?
rotating direction should same as rotating direction of pump(looded from end of motor, impeller rotate as clockwise)??
4. After install mechanical seal(or packing) and coupling, it can easily manual?
rotate shaft of pump and with no attrition phenomenon, then install safe cover of
coupling?? 5. When pump use under condition of suction process, should irrigate pump
or deflate vacuum before drive, pump use under the condition of flow backward
should fill full of pump before drive, after get rid of the air in the pump, please shut? off the gate valve of dischange tube.? 6. Check foundation bolt loosen or not before drive, check stuffing gland whether crooked or not and supply status of lubricant oil and cooling water.?
.? 1. Shut off pressure meter on inlet and outlet (or vacuum) and outlet valve?
(any bypass tube should be shutted off either) drive motor (had better start in advance, confirm correct rotating direction to operate), then open outlet pressure? meter (vacuum), when pump reach to normal rotating speed and instrument to
corr esponding pressure, slowly open outlet valve and adjust to demanded working
status. Under the condition of dischange pipeline being shutted off, continuous? work time of pump can`t exceed 3 minutes?? 2. In process of operation it should pay attention to eletric currency digit of motor and vibration status of pump from time to time??
3. Sealing status: mechanical seal shouldn`t have leakage, heating phenomenon,? packing seal should be in continuous trickling stauts.?
.? 1. Constantly check heating circumstance of pump and motor (temperature of
bearing should`t exceed 75 ) and oil meter without oil surface status (generally,?
it should replace lubricant oil once after every 1500 hours)?? 2. Shouldn`t use suction valve to adjust capacity, prevent generating air erosion?? 3. Pump cannot operate continuously lower than 30% design capacity, if it has?
to operate under such condition, must install by pass pipe to get rid of unnecessary
capacity?? 4. Pay attention to the noise of operation of pump, if discover any abnormal?
state, please eliminate or stop operating timely.?
.? 1. Slow close dischange nozzle pipeline gate valve, and close switch on various?
instrument?? 2. Switch off electric power??
3. If seal utilize outside pilot liquid, need to close outside pilot liquid valve?? 4. If environmental temperature is lower than liquid freezing point, please? drain out liquid cleanly to prevent being splitted?? 5. If beposit if for a long time, please drain out corrosive liquid in pump clearly,?
disassemble and clean each part, especially the seal cavity. Had better reassemble?
it after cleaness, cover with anti-rust oil and block outlet and inlet of poum, besides,?
it should be inspected periodically.
