The cause and treatment of motor winding burnout of fountain pump and its insulation damage are leakage and very dangerous. Do not touch the fountain pump and pipeline with your hands in case of electrification, in order to prevent electric shock, the power supply should be cut off immediately and dealt with again. 1. Fountain pump dehydration operation, cooling deterioration, should increase water level or reduce the installation position of fountain pump. 2. If the voltage of power supply is too low, the voltage of transformer should be adjusted. 3. The windings of motor of fountain pump should be overhauled and replaced if they are short-circuit to ground or turn to turn. 4. If the voltage drop of power cable is too large, it is necessary to replace the larger size cable. 5. Fountain pumps start too frequently and should be operated according to the instructions. 6. When the impeller of the pump is stuck, the impeller should be inspected in time and the impurities of the impeller should be clear. 7. Blockage of fountain pump inlet should be promptly cleaned up and filtered.
