Submersible Pump Repair Steps

Smaller water discharge is a sign of pumps having problems. If left untreated death pump problem a matter of time.
To identify problems that occur, the following steps once and we used to do.
1 If the pump is off, check the capacitor. Change in advance if this component is not functioning.
2 While in running, check the power cord Ampere when the pump is running. If it is high enough (> 10 A) there are several possibilities, 1) the motor gets pretty heavy load. (Foreign bodies such as red soil sediment, ground limestone, etc..), The volume of water is reduced, the water pump works with a very minimum limit / dry for a long time, and 3) the stator coil windings problematic ..

3 submersible pump installation standard safety features to detect the depth of water in the form of the sensor electrode. If the sensor is in good condition, the decrease in the minimum water depth will be detected, and automatically disconnects power to the motor.

Sensor Electroda

Some technicians sometimes just rely on TOR (Thermal Overload Relay) that is attached to Contactor for detecting the condition of the pump and the water depth. Usually the logic is used, when the depth of the water is within the minimum limit, the motor will spin in dry conditions, this will cause the temperature rise in the motor and the motor amperage. The increase in the limit on the amperage setting will cause Contactor TOR disconnects the power.
However, this technique is not recommended, principally ground water depth must be detected by a sensor that detects the condition directly. In the long term use of amperage settings on TOR cause problems stator windings (short).
4 Note the discharge of water, if the high initial bursts then weakened, likely reduced the volume of water in the well. If the eruption weak start at the beginning the motor running, these signs of a motor problem.
5. Raise the submersible pump to the surface. Check the physical condition, is there any foreign objects that impede rotation shaft or impeller. We never met tangled rope, out of nowhere this creature.

Check Submersible Pump

6.-check the water level depth using air-ballast rope. Measure the water depth and distance to the surface of the base. I've also encountered, wells were eroded section essentially, labile soil structure or the possibility of the tremor effect. This information is important when placing the point of the pump and sensor electrode position setting.
7 If you are sure there is no problem with the volume of water in the well. Focus to fix the pump
8 If you feel confident to do the cleaning, first mark along the body casing impeller cover, to ensure the initial position of such pairs. Open impeller one by one, and replace the washer. Then go to the next impeller.
9 Check the condition of the impeller, and shaft. If it is worn or defective, submersible pumps Type your note, then get the original parts in the official supplier.

Impeller kondisi Not Ok

10 Check the resistance coil windings on the rotor, if the prisoner shows a low value, indicating coil problematic, eg leaking. If you encounter this problem, I suggest to replace with a new pump.

11. When finished cleaning and re-assembled the pump. Test first in a water bath, the water flow out and the motor amperage.
12. If nothing changes, do not continue your experiments. Immediately contact your authorized Service Pump and reliable. After completion of service, ask the pump tested back and see the amperage the motor when running. If it is still quite high (> 10 A), do not be accepted. Repair is not complete.
12. I recommend installation be done by a qualified service representative, this is important if you want to get a warranty repair
13. Prepare to be disappointed, if you are not able to submersible pumps in repair. The solution is only one, the new purchase. It happened a year ago, without the guilt, the handyman service says we should menservice pump regularly with the calculation of the package. Lift, Cleaning, and plug it in again. Strange suggestion, instead we use a submersible so low maintenance costs?
