Measures to solve dripping caused by aging of heat exchanger gaskets
Sep 02, 2020

The heat exchanger will leak when the gasket loses its elasticity. In some products, the sealing performance of the heat exchanger is allowed to be adjusted to address dripping due to aging of the gasket, that is, the bolts of the combination heat exchanger are tightened again and the heat exchanger between the elastic gaskets is adjusted. Stress solves the dripping problem. Maximum and minimum stresses are usually given on the nameplate of a heat exchanger with this function. For new heat exchangers, the connection should be fixed with the minimum allowable stress. The fastening force of the heat exchanger can be adjusted once or more depending on the number of heat exchanger plates in each set. Each time the screw is tightened, the nut can be screwed into 3mm. During the tightening process, pay attention to the stress of the adjusting parts, and only allow the heat exchanger to adjust the fastening force at room temperature in the absence of working pressure, so as to prevent water dripping.
