1. Vibration
The vibration of the cooling tower fan has many reasons, which can be checked from the following aspects:
(1) The turbine rubs against the fan and emits a strong vibration;
(2) The support is not strong or stable enough and can cause significant vibration;
(3) The turbine rivets are loose or the turbine is deformed due to pressure during transportation;
p>
(4) Severe vibration caused by loose screws connecting the bracket and air duct, unbalanced blades, corrosion blades, falling balance weights or damaged bearings;
2. Heating
After a period of operation, if the motor overheats, it may be due to one of the following reasons:
(1) The motor bearings are damaged and the corresponding clearance is too small to meet requirements;
(2) Shaft and bearing are installeded crooked and the two bearings are not axial. ;
(3) The resistance of the pipe network is too great and the motor is overloaded;
(4) Power supply The voltage is too low. ---Tengjia Cooling Tower
