混流泵

開(kāi)車(chē)順序：

    1、關(guān)閉出口閘閥

    2、將水注入水泵，以排除進(jìn)水管及泵內(nèi)空氣，可從泵體頂端引水杯注入清水，也可用真空泵注水（開(kāi)動(dòng)真空泵，排除水泵及管內(nèi)氣體在水充滿(mǎn)水泵的同時(shí)，起動(dòng)水泵，打開(kāi)閘閥，停止真空泵）。

3、開(kāi)啟電動(dòng)機(jī)（注意水泵的旋轉(zhuǎn)方向）。

    4、當(dāng)電動(dòng)機(jī)正常運(yùn)轉(zhuǎn)后，逐步開(kāi)大閘閥，達(dá)到所要求的工況后，調(diào)節(jié)填料松緊。若水泵運(yùn)轉(zhuǎn)，軸承溫度等都正常，則可繼續(xù)運(yùn)行。

III.  Starting

Sequence

   1.Close the oulet

sluice valve.

   2. Inject

water into pump to remove the air in water-in pipe and pump which can realized

by injecting clear water from the water diversion cup of the pump body end or

by vacuum pump(start the vacuum pump, remove the air from pump and pipes, start

the water pump when the pump is full of water, open the sluice valve, stop the

vacuum pump).

   3. Start the

motor(pay more attention on the rotation direction of pump)

   4. When the motor runs normally, turn up the

sluice valve gradually, adjust the tightness of padding when gettng to the

required working condition.If the pump runs well, the temperature of bearing is

normal, and it can run sequentially.

4、注意填料的冷卻情況，填料的的調(diào)整，不可太緊，以液體能一滴一滴漏出為準(zhǔn)，填料太緊發(fā)熱、消耗功率。填料太松、使水泵中的液體漏損過(guò)多，降低效率。

Pay more

attention to the cooling condition of padding.The padding can not be too tight,

it is ok that the fluid can leak in drops.The temperature will be high if the

padding is too tight which cumes power.If the padding is too loose, the

fluid leaks too much, the efficiency will be lower.

水泵發(fā)熱

原因：軸承損壞；滾動(dòng)軸承或托架蓋間隙過(guò)?。槐幂S彎曲或兩軸不同心；膠帶太緊；缺油或油質(zhì)不好；葉輪上的平衡孔堵塞，葉輪失去平衡，增大了向一邊的推力。排除方法：更換軸承；拆除后蓋，在托架與軸承座之間加裝墊片；調(diào)查泵軸或調(diào)整兩軸的同心度；適當(dāng)調(diào)松膠帶緊度；加注干凈的黃油，黃油占軸承內(nèi)空隙的60%左右；其特點(diǎn)是，與混流泵、軸流泵相比，揚(yáng)程較高，流量較小，結(jié)構(gòu)簡(jiǎn)單，使用方便。清除平衡孔內(nèi)的堵塞物。

劇烈震動(dòng)

主要有以下幾個(gè)原因：電動(dòng)轉(zhuǎn)子不平衡；聯(lián)軸器結(jié)合不良；軸承磨損彎曲；轉(zhuǎn)動(dòng)部分的零件松動(dòng)、；管路支架不牢等原因?？煞謩e采取調(diào)整、修理、加固、校直、更換等辦法處理。
