During rainy season, many areas, such as city highway tunnel, underground garage, underground mining spot, have to face the same job of flood and sewage water drainage. Our flood draining water pump, outflow ranging 200-5000m3/h with diameter 6-26inch, can be applied in many situations.

Possible faults existed during applications
(Physical faults, please turn to our engineering department for good solutions.)
|
Fault |
Reason |
Solution |
|
No water suctioned in |
Priming water not enough, air existed in suction hose or leakage at connections of suction hose |
Full of priming water, check hose to avoid leakage. |
|
Pump can not suction water |
Check foot valve filter, maybe not open or blocking heavily. |
Check foot valve and make it smoothly, remove blocking material, simplify suction hose, reduce suction lift. |
|
Minor or no outflow |
Discharge hose with big resistance, impeller blocked or rotation speed insufficient. |
Reduce resistance of discharge hose, remove blocking material. Raise speed to rated. |
|
Outflow less than rated |
Impeller blocked or impeller worn out, speed not enough. |
Remove blocking, renew impeller, raise speed. |
|
Pump feeding more power, diesel engine smoking |
Seal too tight, outflow bigger than rated |
Loosen stuffing seal cap, reduce valve to ctrl outflow reasonably. |
|
Abnormal noise in pump, minor or no outflow |
Suction hose bigger resistance, foot valve not smoothly, beyond rated suction lift, air into suction hose. |
Check whether there is blocking, clear foot valve, reduce suction height, clear leakage of suction hose. |
|
Pump vibration |
Diesel engine shaft and pump shaft not same in line. Big gap of bearing. |
Adjust anchor bolts and gasket, make sure assembling shafts in same line. Replace bearing. |
|
Hot bearing of pump |
Less lubricant oil, big gap of worn bearing, shafts not in same line |
Add lubricant oil, replace bearing, adjust anchor bolts making shafts in same line |
|
Big noise |
Shafts not in same line, pump bearing worn out. |
Adjust anchor bolts and shafts in line. Replace bearing. |
