The plate heat exchanger needs to be disassembled and inspected during maintenance, repair or cleaning. Therefore, it is necessary to understand the method and precautions for disassembly of the heat exchanger.

    1. Before disassembling the plate heat exchanger, first measure the compaction length dimension of the plate bundle and make a record (this dimension should be followed when reinstalling).

    2. Remove the clamping bolts and heat exchange plates.

    3. Remove the sealing gasket from each plate. If the rubber pad is stuck in the groove between the two plates, use a screwdriver to carefully separate it. First insert from the easily peelable part, and then separate along its periphery. Do not damage the plates and gaskets. The liquid nitrogen quenching method can also be used to rapidly deform the gasket and then tear it off.

    4. To replace a new gasket, use acetone or other ketone organic solvents to clean the gasket groove. Then evenly spread the adhesive in the sealing groove of the plate.

    5. Use lamp or kerosene penetration method to check whether there are cracks or perforations on the heat transfer plate piece by piece. If there is, it needs to be repaired or replaced in time.

    6. Check whether the heat exchange plate has pits or local deformation. If it exceeds the allowable value, repair or replace it.

    7. If there is debris accumulation in the short pipe or channel of the medium, it should be cleaned in time.

    8. When disassembling the titanium plate, it is strictly forbidden to contact with the open flame to prevent oxidation.

    9. Check whether the sealing gasket has aging, deterioration, cracks and other defects. Do not scratch hard objects on the surface.

    10. It is strictly forbidden to accumulate solid particles, such as sand and iron slag, on the surface of the gasket and the plate.

    The above is the disassembly method and precautions of the plate heat exchanger. For more related product introduction, please consult Beijing Propellent.
