.? 1. Shouldn`t press weight of pipeline on the pump while installing, otherwise? will damage water pump easily??

2. Must tighten foundation bolt while installing, and check the unit in every

period to prevent it loosening, so as to avoid the drastic vibration that caused by

operation of water pump and eff ect the performance of pump?? 3. Before water pump installation, please check carefully whether there are?

hard substance (such as stone, iron sand etc.) in port to effect operation of water pump?? 4. In order to maintain conveniently and operate safely, it should install an

adjustable valve on the inlet and outlet pipeline and install a pressure meter on inlet?

and outlet nozzle flange. As to high head pump, in order to prevent water hammering,?

it should install a check valve on the front of outlet gate valve to deal with event? of eletric cut-off s uddenly etc. so as to ensure water pump operate under the best? working status and prolong sevice lift of water pump??

5. When pump is used in suction head occasion, it should install base plate and

Check foundation bolt loosen or not before drive, check stuffing gland whether crooked or not and supply status of lubricant oil and cooling water?? 7. AFB should connect with cooling water pipe to us e as cooling sealing

equipment.

.? 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 ad- vance, 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.

本型號泵可根據(jù)不同的使用條件裝不同形式的機(jī)械密封， 如內(nèi)

裝單端面平衡型和非平衡型，雙端面平衡型及非平衡型，外裝式機(jī)

械密封等 根據(jù)所選用密封式的不同，其使用方法和注意事項(xiàng)也有所

不同，具體情況參閱機(jī)械密封安裝使用說明書、 “煉油

廠、化工及石油工流程用離心泵通用技術(shù)條件”，下面僅提幾點(diǎn)一 般應(yīng)注意的事項(xiàng)： 、由于機(jī)械密封一般適用在清潔的，無懸浮 顆粒的介質(zhì)中使

用，因此，對新安裝的管路系統(tǒng)和儲液灌，應(yīng)認(rèn)真沖洗干凈，嚴(yán)防

固體雜質(zhì)進(jìn)入機(jī)械密封端面而使密封失效。 、在易結(jié)晶的介質(zhì)中使用機(jī)械密封應(yīng)注意經(jīng)常沖洗。停車后重

新起動前，要將機(jī)械密封上的結(jié)晶清洗干凈。 、拆卸機(jī)械 密封應(yīng)仔細(xì)，不許用手錘、鐵器等敲擊，以免破壞

靜環(huán)密封面。 、如果有污垢拆不下來時(shí)，應(yīng)設(shè)法清除污垢，沖洗干凈后再進(jìn)

行拆卸，以免損壞密封元件。 、安裝機(jī)械密封前，應(yīng)檢查所有密封元件是否有失效或損壞， 如有則應(yīng)重新修復(fù)或更換。 、應(yīng)嚴(yán)格檢查動環(huán)與靜環(huán)的相對摩擦密封面，不允許有任何細(xì)

微的劃痕，碰傷等缺陷。所有零部件，包括泵體、葉輪、密封腔等

在裝配前均應(yīng)沖洗干凈，尤其是動、靜環(huán)端面，要用清潔、柔軟的

布或棉紗認(rèn)真擦拭干凈，然后涂上一層清潔的油脂或機(jī)油； 、裝配中要注意消除偏差，緊固螺釘時(shí)，要均勻擰緊，避免

發(fā)生偏斜，使密封失效。 、正確的調(diào)整彈簧的壓縮量，泵安裝好以后，以手扳轉(zhuǎn)子時(shí)， 應(yīng)感覺到密封彈簧既有一定的壓縮量，而又能輕快、靈活地轉(zhuǎn)動， 滑有咬緊的感覺，如感覺太緊或盤不動，則應(yīng)適當(dāng)調(diào)松一些。 、對有外部沖洗的機(jī)械密封，起動前應(yīng)先開啟沖洗液，使密封

腔內(nèi)充滿密封液。停車時(shí)，先停泵，后關(guān)密封沖洗液。

This kind of pump can according different operating condition to install different type of mechanical seal, different sealing type with different operating method

and attention, detailed content refer to mechanical sealing installation manual,? GB3215-82 refinery, the following is general attention for reference:? 1. Due to mechanical seal is generally suitable for clean with no suspending medium, therefor e, if should clean new insta llation pipeline system and liquid

storage tank carefully to prevent dirt entering into end of mechanical seal, make?

seal inefficiently.? 2. Mechanical seal is used in easy crystal medium should wash it constantly,? before restart it should clean crystal on mechanical seal.?

3. Remove mechanical seal must be careful, dont beat with hand, iron tool etc.?

in order to avoid to damage dynamic and static circle facing.? 4. if it cannot be removed due to dirt, try to clean dirt, wash neatly to remove,?

so as to avoid admaage sealing component. 5. Before install mechanical seal should check all of sea ling components whether have been damaged or disabled, if there are any damaged or disabled comp- onents should be reqaired or replaced timely.? 6. Strictly check dynamic and static circle oppositive attrition facing even with

no tiny nick and scar. All of components including pump casing, impeller, sealing

cavity etc. should be wash cleanly, especially the dynamic static circle end should

be rubbed by soft cloth or cotton gauze, then cover clean grease or engine oil on it. 7. Pay attenti on to eliminate eccentricity while assembling, equally tighten

screw, prevent, to be inclined and make seal invalid.? 8. Properly adjust compression ratio of s pring, atte pump installation, when manually turn rotor will feel sealing spring has definite compression ratio and also?

can turn trippingly and neatly without snap sense. If feel too tight or cannot turn,?

please adjust to some what loose.? 9. As to outside wash mechanical seal, please open lotion before start to fill?

sealing cavity with sealing lotion. When stop operating, secure pump in advane?

then close sealing lotion.

會造成泵內(nèi)汽蝕。

①盡可能縮短吸入管路， 使泵靠近液面，以減少

吸程上的管路阻抗。

②吸程管路上不可布設(shè)

凸起管，以防氣阻造成

★金屬材料耐腐蝕性能通常用腐蝕深度 又稱腐蝕速度 作為評定金屬材料耐腐蝕性能的一項(xiàng)主要指標(biāo)。 ★腐蝕深度是指金屬材料在單位時(shí)間內(nèi)腐蝕的金屬深度，單位用“毫米 年” 表示。 ★按照腐蝕程度的不同，通常分為：腐蝕深度小于 的材料，稱為耐腐蝕性能材料；腐蝕深度為 ，稱為尚耐腐蝕材料；腐蝕

深度大于 ，稱為耐腐蝕性不好的材料。 ★一般泵與介質(zhì)接觸的主要零件的材料選項(xiàng)用在指定介質(zhì)情況中，尚耐腐蝕性材料就可以。 ★為便于用戶選用泵型，根據(jù)所輸送介質(zhì)條件，選擇適宜泵的主要零件材料耐腐蝕性能，本說明書匯編了 、 、 、 、 、 等材料耐腐蝕性能表 表 表

供選泵時(shí)參考。
