    (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．
