deal with the aging of the gaskets of plate heat exchangers
The softening of the plate heat exchanger gasket is related to pressure and temperature. When the gasket loses its elasticity, the heat exchanger will leak. In some products, in order to solve the leakage phenomenon caused by the aging of the gasket, the sealing performance of the heat exchanger is allowed to be adjusted, that is, the bolts of the combined plate heat exchanger are tightened again to adjust the elastic gasket between the heat exchangers. The pressing force can solve the problem of dripping. On the nameplates of heat exchangers with this function, the allowable large and small stresses are generally given. For new heat exchanger plate groups, the connection should be fixed with a small allowable stress. Depending on the number of heat exchanger plates in each group, the tightening force of the heat exchanger can be adjusted one or more times. Each time you tighten, you can screw the nut into 3mm, and always pay attention to the stress of the adjustment plates during tightening, It is only allowed to adjust the tightening force of the heat exchanger without working pressure at room temperature to prevent dripping.
For plate heat exchangers whose stress adjustment range is not given on the nameplate, the stress values are generally given in the parts drawings. When tightening such plate heat exchangers, the tightening torque should not be lower than the value specified in the drawing, Because it is related to the assembly quality and assembly deformation of the plate heat exchanger. When the tightening torque reaches the required value, the elastic gasket can be replaced in a planned way. For plate heat exchangers used in critical production equipment and corrosive media, a spare set of seals is recommended.
