產生原因 |
排除方法 |
|
水 泵 不 出 水 |
1．泵內未注滿水 2．進水管或密封處漏氣 3．水泵反轉 4．進水管太長 5．吸程過高 |
1．往泵內注滿水 2．檢修進水管，排除泄漏 3．檢查糾正 4．縮短進水管 5．降低吸程 |
|
出 水 量 不 足 |
1．葉輪堵塞 2．密封環處嚴重磨損、間隙大 3．壓頭過高 4．進水管漏氣 5．吸程過高，局部產生汽蝕 |
1．排除堵塞物 2．更換密封環 3．降低壓頭 4．檢修進水管 5．降低泵安裝高度或縮短進水管 |

Failure |
Causes |
Remedies |
|
No water discharmng |
1．Pump
is not full ofwater． 2．Air
leakage exists in the inlet pipe or in the sealing part． 3．Revolution
direction reversed． 4．Length
of inlet pipe is too long． 5．Suction
lift is too high． |
1．Fill water into pump till full
2．Repair
the inlet pipe，remedy The leakage． 3．Cheek
and correct． 4．Shorten
the inlet pipe． 5．Lower
the suction lift． |
|
Less flow |
1．Impeller
blocked． 2．Excessive
wear-down in way of the sealing ring/Excessive clearance． 3．The
liftis toohigh． 4．Air
leakage exists in the inlet pipe． 5．Suction
lift is to high．Local vapour etching appears． |
1．Clear
the blockage． 2．Replace
the sealing ring． 3．Lowerthe
lift 4．Repair the inlet pipe．
5．Lowertheposition
of the pump or shorten the inlet pipe． |
