Plate heat exchanger maintenance: What are the common failures of plate heat exchangers? _
316 workers who frequently operate plate heat exchangers will know that plate heat exchangers sometimes fail. What is the reason? Today I have sorted out some plate heat exchanger repairs for you: plate heat exchangers often occur failures, today I share with you: medium leakage: there are two ways of leakage and leakage. When leaking, the amount of medium is small and does not continue; when leaking, the amount of medium is large and the medium continues. Leakage occurs mainly in the seal between the plates, the end of the plate and the inner side of the compression plate, and the corrugated groove of the plate. The medium inlet and outlet pressure difference is large: the medium outlet pressure is too small, and the pressure drop exceeds the design requirements, which indirectly affects the system's heat exchange effect and cannot meet the system's flow and temperature. Can not get the heating (or cooling) medium operation. Medium mixing: When the medium on the higher pressure side is mixed into the medium on the lower pressure side, the temperature and pressure will be abnormal. If the medium is corrosive, it will also cause corrosion of other equipment in the system. It usually occurs in the secondary sealing area or diversion area. The cooling effect is unclear: the secondary feature is that the outlet temperature of the cooled medium is too high, which does not meet the design requirements.
