Temporary treatment method for aging gasket plate heat exchanger: softening of elastic gasket is related to pressure and temperature. When the gasket loses elasticity, the plate heat exchanger will have drip leakage. In some products, in order to solve the drip leakage caused by aging gasket, it is allowed to adjust the sealing performance of the heat exchanger, that is, tighten the bolts of the combined plate heat exchanger again, The pressing force of the elastic gasket between the heat exchangers is adjusted to solve the dripping problem.
Generally, the maximum and minimum allowable stresses are given for plate heat exchangers with this function. For new plate heat exchangers, the minimum allowable stress should be used for connection and fixation. Depending on the number of plate heat exchangers in each group, the tightening force of plate heat exchangers can be adjusted once or several times. When tightening each time, the nut can be screwed in 3mm, In addition, it is only allowed to adjust the tightening force of the heat exchanger without working pressure at room temperature to prevent dripping. This is a temporary treatment for aging gasket plate heat exchanger .
For plate heat exchanger without stress adjustment range, stress value is generally given in the part drawing. When tightening this kind of plate heat exchanger, the tightening torque should not be lower than the value specified in the drawing in any case, because it is related to the assembly quality and assembly deformation of plate heat exchanger, For the plate heat exchanger used in important production equipment and corrosive media, it is recommended to have a set of spare seals. When the warehouse temperature is 18 ?, the seals of plate heat exchanger can be stored for 3 years in transparent plastic packaging.
In principle, the fixation of plate heat exchanger seals can be divided into adhesive fixation and non adhesive fixation. The shape of gasket should be consistent with the shape of plate heat exchanger seal. It must be pointed out that the adhesive fixation method does not have any effect on the sealing function.
