Air Fin Cooler

Make sure the belt pulleys are accurately aligned in the same plane, so that the belt engages each pulley straightly. Make sure the belt tension is adequate, so that the belt doesn't slip. If slippage has been a problem, you probably can see rubber dust in the drive enclosure. Is there anything in the atmosphere that would degrade the belt over time? If so, there might be a different elastomer that would work. Check also that the belt isn't bending around too small a pulley. A cogged type of V-belt could help with this, if it isn't already that type.

we are already using the timming belts there,

previously we are not using mist cooling, after around one year w started the same.

we also clage the belts, some new belts were also broken, the motor killowats is 45.

please guide us what to do

Maybe the next step would be to check the engineering of the drive--whether the belt selection can handle the 45 kw (~60 hp) load at the given pulley speeds and diameters.

I think the "crabber' will agree that without mist, no belt failure; and with mist, belt failure would mean a decision is in order.

Don't mist, or keep the mist away from the belts. Wet belts don't work.

And, as stated, 60HP may be too much for wet belts.

dear,

any time mist not touches the belts, coz the direction of mist down words and the fan throws the air in upwards.

most of the belts failure accrued in the night time, when the temperature get lowered.

i think the belts were damage due to the sudden change in the temperature.

now we have decided to stop the mist and from that time, no failure occured.

check the pulley alignment and check also the type of belt used. there is a recommended type of belt for every pulley specially on heavy duty application.
