What are the performance and reasons of cooling tower motor overload

  The definition of cooling tower motor overload: cooling tower motors have a certain operating output power, which is called the maximum power, and its unit is watts (W). In some cases, the specific application output power of the cooling tower motor exceeds At the maximum power of the motor, people call this type of situation the cooling tower motor overload. In the operation of cooling tower machinery and equipment, how do people judge whether the cooling tower motor is running under overload? What is usually the manifestation? The cooling tower manufacturer trlon will discuss with you.9n2Cooling tower noise reduction treatment manufacturer

  Cooling tower motor load operation has the following specific manifestations:

  A. Cooling tower motor load operation

  1, the cooling tower motor heat dissipation increases;9n2Cooling tower noise reduction treatment manufacturer

  2, the cooling tower motor has a low beep, and the vibration is usually;.9n2Cooling tower noise reduction treatment manufacturer

  3, the cooling tower motor speed ratio is reduced, and it may even be reduced to zero;9n2Cooling tower noise reduction treatment manufacturer

  4. If the load changes drastically, the cooling tower motor will produce a situation where the speed is higher than that of the hour;9n2Cooling tower noise reduction treatment manufacturer

  B. The specific reasons for the cooling tower motor load operation include:

  1, the voltage of the cooling tower motor is too high or too low;9n2Cooling tower noise reduction treatment manufacturer

  2, the cooling tower motor is exposed to moisture or corrosive gas for a long time, which reduces the insulation resistance;9n2Cooling tower noise reduction treatment manufacturer

  (1) The winding method of the cooling tower motor does not meet the standard. The windings that were originally Y-connected were mistakenly △-connected during maintenance.9n2Cooling tower noise reduction treatment manufacturer

  (2) Mechanical reasons: For example, the torque of the cooling tower motor is too large or the cooling tower motor is damaged (bearing vibration), etc.;9n2Cooling tower noise reduction treatment manufacturer

  (3) The load of the cooling tower motor is too heavy;9n2Cooling tower noise reduction treatment manufacturer

  (4) The cooling tower motor bearing is lack of oil, dry grinding or rotor machinery is not uniform, causing the cooling tower motor current to exceed the rated value.9n2Cooling tower noise reduction treatment manufacturer
