During the use of the plate heat exchanger, it is inevitable that the plates of the plate heat exchanger will be misaligned. After the plates are misaligned, leakage or external leakage will occur quickly, and must be dealt with in time to ensure the normal operation of the heat exchange equipment.
If you want to solve the problem of heat exchanger plate misalignment, you must first understand the reasons for the plate heat exchanger plate misalignment.
1. Reason
(1) In the process of long-term use, the multi-pass combination, and the flow and pressure of the medium in the heat exchanger also change greatly. When the heat exchanger cannot resist this pressure, the plate heat exchanger plate Dislocation phenomenon.
(2) The sealing gasket of the plate heat exchanger slips away from the gasket groove, and the plate will also be misaligned.
2. Solution
(1) On-site maintenance personnel can first draw out the damaged plates and leaked plates in pairs (A plate + B plate). If there are fewer misplaced plates, the number of reduced flow channels is not much. At the time, the equipment can be used after assembly, and the impact on production is not great.
This solution is applicable to the situation where there are no new plates to replace on site and the equipment cannot be shut down. If conditions permit, it is best to shut down for replacement and maintenance.
(2) When the sealing gasket of the plate heat exchanger slips away from the gasket groove, it is necessary to replace the deformed plate and the gasket sliding away from the gasket groove in time when dealing with this dislocation phenomenon.
