Treatment method for medium leakage of marine heat exchanger
1. In the non pressure state, re clamp the equipment according to the clamping size provided by the manufacturer, the size should be uniform, the deviation of the pressing size should not be greater than ± 0.2N (mm), n is the total number of plates, and the parallelism between the two pressing plates should be kept within 2mm.
2. Mark the leakage part, then disassemble the marine heat exchanger, check and solve the problem one by one, and reassemble or replace the gasket and plate.
3. If there are no spare parts, the deformed parts can be temporarily removed and then reassembled for use.
4. When reassembling the disassembled plates, clean the plate surface to prevent dirt from adhering to the gasket sealing surface.
