Causes and treatment of plate dislocation of marine heat exchanger
The causes and treatment methods of plate dislocation of marine heat exchanger are as follows:
Generally, the reasons for its dislocation are multi pass combination and long-term use. At the same time, the medium flow rate and pressure change greatly. At this time, if the pressure cannot be resisted, the plate will deform and the sealing gasket will slide away from the gasket groove.
The damaged plates and leakage plates can be pulled out in pairs. If the number is not too much, the reduced number of flow channels is not too much. If the number is not too much, it will not have a great impact on the production if it is used after assembly. This means that the equipment cannot be replaced on site, and the equipment can not be shut down. If conditions permit, replacement and maintenance are carried out, and the sealing gasket slips away from the gasket groove. To deal with this dislocation, the deformed plate and the gasket sliding away from the gasket groove should be replaced in time.
After the plates are misplaced, sometimes leakage will appear quickly; although some of them do not leak quickly, they are a hidden danger of leakage, so they should be treated in time. The equipment needs to be maintained in the process of operation.
