Plate heat exchanger maintenance: common failures of plate heat exchangers? _
191 Those who often use plate heat exchangers know that there are several common failures of plate heat exchangers, and the frequency of occurrence is still quite high. Today I will share with you the maintenance of plate heat exchangers: plate heat exchangers Common faults of the device? External leakage is mainly manifested as leakage (small amount, discontinuous water droplets) and leakage (large amount, continuous water droplets). The main places where leakage occurs are the seal between the plate and the plate, the two sealing leak grooves of the plate, and the inner side of the end plate and the compression plate. The main feature of fluid flow is that the medium on the higher pressure side is strung into the medium on the lower pressure side, and abnormal pressure and temperature will appear in the system. If the medium is corrosive, it may also cause corrosion of the gasket of the plate heat exchanger. Liquid leakage usually occurs in the diversion area or the secondary sealing area. The inlet and outlet pressure drop of the medium with large pressure drop exceeds the design requirements, or even many times higher than the design value, which seriously affects the system's requirements for flow and temperature. In the heating system, if the pressure drop on the hot side is too large, the primary side flow will be seriously insufficient, that is, the heat source is not enough, resulting in the secondary side outlet temperature that cannot meet the requirements. The main feature of the heating temperature that cannot meet the requirements is that the outlet temperature is low, which fails to meet the design requirements.
