How Maintenance Plate Heat Exchanger?
The softening of the plate heat exchanger gasket is related to the pressure and temperature. When the gasket loses its elasticity, the heat exchanger will leak. In some products, in order to solve the dripping phenomenon caused by the aging of the gasket, the sealing performance adjustment of the heat exchanger is allowed, that is, the plate heat exchanger are tightened again, and the elastic gasket between the heat exchangers is adjusted. The pressing force solves the problem of dripping. On the nameplate of a heat exchanger with this function, it is generally given that large and small stresses are allowed. For new heat exchanger sets, the connection should be fixed with a small allowable stress. Depending on the number of heat exchanger plates per group, the tightening force of the heat exchanger can be adjusted one or more times. Each time the screw is tightened, the nut can be screwed in 3mm, and the stress of the adjusting piece is always paid attention to during the tightening process, and Only allow the heat exchanger without working pressure to adjust the tightening force at room temperature to prevent dripping.
