How to install E18 Plate Heat Exchanger When Maintance?
1 Disconnect pipework from pressure plate
• disconnect pipework from pressure plate
Taking Out Heat Exchanger Plates
• remove the nuts (12a) versus clockwise
• losen all nuts for tensioning bolt (12) crosswise
• unscrew nuts for tensioning bolt (12) from tensioning bolt (1)
• remove washer for tie bar (13)
• remove tensioning bolts (1)
• push pressure plate (10) away from plate pack
• swing out first heat exchanger plate at bottom 20 - 30 cm in
longitudal
direction [1]
• swing out plate laterally under an angle of
30 - 45° [2]
• take the plate off the frame
• remove plate by plate in the same manner
• observe the sequence and face position of plates - after cleaning
they must be
installed back the same way
2 Cleaning of Heat Exchanger Plates
• rinse each plate with a suitable detergent (must neither attack
gasket nor plate) information about suitable detergents can be
obtained from Heat Exchanger manufacturer
• clean plates with a soft brush
• gaskets not to be exchanged:
- avoid soaking of plate in cleaning solution
• gaskets to be exchanged:
- soak plate in hot cleaning solution (approx. 100°C)
• at thick layers of scaling :
- soak plate in hot cleaning solution (approx. 100°C)
DO NOT use:
- steel brush
- steel scraper or similar
3 Re-assembling
• re-install again the cleaned plates
observe
- original sequence and position of each plate (as per numbers and
plate arrangement drawing)
- gaskets installed and in good order
• fit individual plates (lateral insertion under 30 -
40°inclination)
• push pressure plate (10) to the plate plack
• re-insert tensioning bolts (1) back in lateral slots
• fit washers for tensioning bolt (13) to the tensioning bolts (1)
• tension the plate pack with the nuts for tensioning bolt (12)
- uniformly
- crosswise
- observe parallelism between pressure plate (10) and frame plate
(4)
• observe tesnioning limit on name plate
• avoid:
- overtensioning (below min. tensioning limit on name plate)
- too little tensioning (above max. tensioning limit on name plate)
• fix the nuts for tensioning bolt (12) by mounting the nuts (12a)
• connect pipework again
• start up Heat Exchanger as per section 6
