758 plate heat exchanger gasket is a very critical component of the plate heat exchanger. The application range of the plate heat exchanger is also largely limited by the gasket, which can seal in the strong corrosive medium. The requirements for gaskets are particularly high. As an important part of the plate heat exchanger gasket, it has a great impact on the service life of the plate heat exchanger. If these gaskets are hardened and lose their due elasticity, the heat exchange equipment 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 prevent the heat exchange medium from mixing. Therefore, the plate heat exchanger gasket is considered to be very important and necessary for the plate heat exchanger Carry out demanding components. Let's take a look at the common characteristics and replacement steps of plate heat exchanger gaskets in detail. Interested friends are welcome to read the following. 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, and 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 should be carried out in the following order ① Remove the used 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 about the common characteristics and replacement procedures of plate heat exchanger gaskets, I hope it will be helpful to you.
