USE AND MAINTAIN
1.This submersible pump can not be able to work dry or above the water,otherwise the pump will be burn.
2.Check the voltage if as same as nameplate before use.
3.When connect the wire,should connect the red wire to storage battery's positive pole(+), another blue one should connect with cathode pole(-).48V pump already have plug,charge directly with storage battery.
4.Pump can not use without water more than 10seconds,otherwise will destroy the mechanical seal.
5.Should tie the rope to the pump's handle before immerse into the water before work,can not snap directly.
6.If you need add the cable length,the cable wire diameter should more than 1.5mm,the shorter the better.
7.If there is solid in water,should put the pump where have filters to avoid to blocking.
FAULTS AND REJECT
| FAULTS |
REASON ANALYSIS |
HANDLING METHODS |
| NO FLOW |
1.Transposition
positlve pole(+) and cathode pole(-)
2. No power
3.Impeller crack or block
4.Cable is destroyed or poor contact,or carbon brush wear out. |
1. Connect right positlve pole(+) and cathode pole(-)
2.Change power
3.Clean impeller blocked thing.
4.Check the cable or change it. |
| LACK OF WATER |
1. Voltage is lower or power is not enough
2. Cable is too long or wire is less
3. Use Head meter to higher
4. Inlet filter is blocked. |
1. Increase power voltage and power
2. Shorten cable,increase wire diameter.
3. Decrease Head meter.
4. Clean solids |
| BIG NOISE |
1. Bearing wear out
2.Impeller has solid or destroved |
1. Change bearing.
2. Clean solids or change impeller |
