(2)起前檢查泵的轉(zhuǎn)向，從電機方向看應(yīng)為順時針。
Check the d i rection of ryeolution for
the pump when starting the motor，the di rection should be
clokwise in view of motor slde．
(3)水泵運行時，應(yīng)檢查各儀表讀數(shù)是否正常，儀表指針應(yīng)無急劇跳動。
when the pump is operatrng，eheck if the reading for
all instruments are abnormal。the pointer of in
strlments should be nOStrong jumping．
(4)長期工作時應(yīng)經(jīng)常檢查吸入管路上的接頭、旋塞等的緊密性，以防空氣流入，破壞泵的工作。
when the operaton i s for a longer time，tightnes s must be checked
all the times for the connectors on snction pipe，cocks
and others as to avoid the air lcakage，otherwise the
pumping condition wonld be failed．
(5)經(jīng)常注意電動機的發(fā)熱及機減密封泄漏情況。
Look for heating up motor and
the condition of mechaniool packing leakage．
9、泵的停車 Shutting down the pump：
(1)關(guān)閉電動機后，必須關(guān)閉吸入閥和壓出閥。
Suction valve and pressing-discharge
valve must be closed up after the motor being shutted down．
(2)短期停車無需特殊保養(yǎng)，如長期停車，則應(yīng)將泵體內(nèi)的水放干，進行必要的防銹措施后保存 如發(fā)現(xiàn)有不正常情況應(yīng)立即進行檢修。
when the pump is shutted
down for a short time，it will require no special maintenace；but if
shutting down for a long time，warer in the Pumpbody
should he discharged to dry，after empling water，the necessary corrosion-vesistant measures must be taken and then
reserve．once the abnormal condition iS found，check and remedy must be taken at once．

泵不吸水 fovr pump failed |
a．泵體內(nèi)沒有剩余水。 there is no excess b．泵吸入空氣．可能通 過吸入管的各接頭處吸入空氣。 Suck in air．This
takes place possibly in the connectors of suction pipe。 |
a．向泵體內(nèi)灌水。 Fill-up pumpbody with water b．檢查吸入管各接頭處，消除漏氣。 Check for
connectors of suction pipe and eliminate leaekage if required． |
