Trouble phenomenon Remedy No water or intermittent water or water less 1. Motor did not start (such as voltage, wire too thin too long, the cable pressure drop is too large or the pump stuck start up) 1. To eliminate the circuit failure to identify the card Cause of death and exclusion 2.Management blockage or filter plugging 2.Purchase the gambler 3.Pipeline rupture 3.Repair rupture 4. Suction port out of the water 4.Power down the submersible pump, if the heat does not come out, may be more than The submersible pump head range, it is recommended to change the pump 5. Submersible pump to the contrary 5. Exchange any two connectors cable 6. Impeller ring and seal ring wear 6. Replace the new impeller, seal ring current is too large or current pointer table swing 1 Large flow, low head out of the scope of use, the motor overload 1. Reduce the flow of 2. Motor graphite bearing wear, pump rubber bearing or bearing wear 2. Replace the new bearing or thrust plate 3. Thrust shaft wear, impeller under the seat. Replace the thrust shaft or thrust plate 4. The pump shaft is bent. Bearings are not the heart 4. Motor shaft bending bending resistance to geothermal insulation resistance of less than 0.5 Euro 1. Solenoid insulation aging or broken 1. Disassemble the winding, with self-adhesive tape bandage damage or rewound the new coil 2. Rubber cable Damaged 2. Identify damage, re-bandage with self-adhesive tape 3. Seal joint failure 3. Disassemble. Reconnect the motor can not be started and there is a buzz 1. Wire disconnection or switch disconnection (single-phase operation) 1. Repair broken wire, connect the fuse 2. Motor shaft bearing axle 2. Repair or replace the bearing , Repair shaft 3. Impeller and foreign body stuck in the pump 3. Removal of foreign matter 4. Voltage is too low 4. Adjust the voltage Vibration of the motor 1. Motor rotor imbalance 1. Rotor balancing 2 impeller imbalance 2. Impeller Static balance 3. Pump shaft bending 3. Straightening 4. Bearing (sleeve) wear 4. Bearing replacement, sleeve motor windings burned 1. Motor water shortage 1. Note must be filled with water 2. Single-phase operation 2. Check Adjust the boot protection device 3. Overload operation for a long time 3. Buck load, so that current and voltage can not exceed the nameplate
