Air Cooled Press Machine Maintenance

The reason of poor cooling effect of air cooler and its treatment

The Air Cooled Press Machine has poor cooling effect for the following reasons: fouling on the inner wall of the finned tube; non-flow of the finned tube to block the medium; scaling of the fins; bending and deformation of the finned tube; fin lodging; wet air cooling or combined air cooling The finned tube fins are too closely spaced.

For the poor cooling effect such failures are mainly taken to remove the air cooler for cleaning or cleaning (chemical cleaning or physical cleaning), repair damaged fins and other methods to solve.
