Precautions for maintenance of plate heat exchangers
Post time: 2022-04-15 14:16:17 Views: times

Plate heat exchangers are an important part of heat exchange technology in process industry equipment. The elastomeric gasket that seals between the individual plate heat sinks is a wearing part and a part that is prone to aging under natural conditions. Its service life has an important influence on the service life of the plate heat exchanger. If these seals thermally harden and lose their original elasticity, the heat exchanger may not function properly. The following factors have a significant impact on the service life of elastomeric gaskets: 

 
1. How the heat exchanger works (continuous or discontinuous); 
 
2. The corrosiveness of the cooling medium and the cleaning agent used; 
 
3. Working temperature; 
 
4. Work pressure; 
 
5. The stress of the elastic gasket is large due to excessive pressure and unbalanced pressure; 
 
6. Natural aging. The softening of the elastic gasket is related to pressure and temperature. When the gasket loses elasticity, the heat exchanger will leak.
