781 plate heat exchanger gaskets are extremely critical components of plate heat exchangers. The application range of plate heat exchangers is also largely limited by gaskets, which can seal in strong corrosive media. The requirements for gaskets are extremely stringent. Plate heat exchanger gaskets have an important impact on the service life of plate heat exchangers. If these gaskets harden and lose their due elasticity, the heat exchanger may not operate normally, because the gasket must not only seal the medium , So that it does not leak to the external environment, but also to prevent the mutual mixing between the heat exchange media. Therefore, the plate heat exchanger gasket is considered to be a very important part of the plate heat exchanger. Let us take a look at the selection and replacement of gaskets for plate heat exchangers. Due to the continuous expansion of the application field of plate heat exchangers, different media and processes have different requirements for temperature resistance, pressure resistance and corrosion resistance. It is obviously impossible to use a 'universal' gasket to adapt to all situations. Instead, gaskets of different materials should be used for different situations. The commonly used gasket cross-sectional shape is a six-sided row. Commonly used gasket types include natural rubber, neoprene, EPDM, silicone rubber, fluororubber, asbestos fiberboard, etc. If the gasket of the plate heat exchanger is in use, it should be replaced in time if it leaks, breaks, or ages. The replacement procedure of the plate heat exchanger gasket is as follows: ① Remove the waste gasket. When disassembling, make sure that there are no scratches in the gasket groove. ② Use acetone, methyl ethyl ketone or other ketone solvents to remove the residual glue in the gasket groove. ③ Clean the gasket groove and gasket with a clean cloth or cotton yarn. ④ Apply the adhesive evenly to the gasket groove. ⑤ Stick a clean new gasket on the board. ⑥ The plate with the gasket should be placed in a flat, cool and ventilated place before it can be installed and used after it has dried naturally. The above is a specific introduction to the selection and replacement steps of the plate heat exchanger gasket.
