Matters needing attention in the maintenance of plate heat exchangers?
Plate heat exchanger is an important part of heat exchange technology in process industry equipment. The elastic gasket sealed between various plate radiators is a kind of vulnerable part, and it is also a kind of part which is easy to aging under natural conditions. Its service life has an important influence on the service life of the plate heat exchanger. If these seals harden and lose their original elasticity, the heat exchanger will not work properly. The following factors have an important effect on the service life of the elastic gasket.
1, the working mode of heat exchanger (continuous or discontinuous);
2, the heat dissipating medium and the corrosiveness of the cleaning agent used.
3, working temperature;
4, work pressure;
5, due to excessive pressure and uneven pressure, the stress of the elastic gasket is larger.
6, natural aging. The softening of elastic gasket is related to pressure and temperature. When the gasket loses elasticity, the heat exchanger will leak.
