Today, the cooling tower manufacturer China Trlon Energy-saving Air Conditioning Equipment Co., Ltd. will analyze the reasons for the short circuit of the square cooling tower:
1. Overload operation of cooling tower equipment makes the water pump motor run at rated current or over-rated current for a long time. Special attention should be paid to that the starting current of the cooling tower water pump motor is 3-5 times the rated current, so it should be avoided to start the equipment with load or full load operation (mainly depends on the matching of the pump motor’s rated current and the normal operating current margin)
2. The water pump motor of the square cooling tower works in a humid working environment. The cooling tower should check the ground insulation and phase-to-phase insulation of the coil before starting the water pump motor. The insulation requirements of different voltage levels are also different, and you can refer to the relevant standards for inspection. During the operation of the pump motor, attention should be paid to the waterproof and moisture-proof of the pump motor.
3. The mechanical failure of the cooling tower pump causes the water pump motor to be overloaded, the current is too large and the coil is burnt.
4. There is a problem with the heat dissipation of the water pump motor of the square cooling tower. Generally, water pump motor coils are air-cooled shells, and cooling tower submersible pumps are water-cooled shells. Large-scale water pump motors are mostly cooled by air-to-air heat exchangers and air-to-water heat exchangers. If the cooling water (air) is cut off, the coil cannot dissipate heat, and the coil may be burnt.
