In addition to its own quality problems, the short-circuit failure of a closed cooling tower can also be caused by the following reasons. Next, the editor of trlon will tell you the common faults and solutions that cause short circuits in closed cooling towers.
1. The cooling tower mechanical equipment is running under load, so that the motor and water pump will run at the working voltage or over the working voltage for a long time. In particular, it should be noted that the starting current of the cooling tower motor water pump is 3-5 times the working voltage, so it is reasonable to try to avoid starting the mechanical equipment with load or overload operation (the working voltage of the important load motor water pump and normal conditions (Matching volume of lower running current)
2. Closed cooling tower motor and water pump work daily in a humid office environment. The cooling tower should require the ground insulation layer and the two-color insulation layer of the coil before the motor water pump is started. The requirements for the insulation layer of different working voltages are also different. You can refer to the relevant standards. Pay attention to the moisture-proof and waterproof of the motor water pump during the whole operation of the motor water pump.
3. The common failures of the cooling tower pump machine cause the motor and water pump to be overloaded, and the current is too much to burn the coil.
4. The heat dissipation of the closed cooling tower motor water pump is difficult. Usually the motor and water pump coils are air-cooled casings, and the cooling tower submersible sewage pump is a water-cooled heat dissipation casing. Large and medium motor water pumps mostly use air-to-air heat exchangers and air-to-water heat exchangers for cooling. If the cooling circulating water (gas) is disconnected so that the coil cannot dissipate heat, it is likely to damage the coil.
