Under what circumstances does the plate heat exchanger gasket need to be replaced?
Under what circumstances do the gaskets of the 853 plate heat exchanger need to be replaced? External leakage is mainly manifested as leakage (small volume, discontinuous water droplets) and leakage (large volume, continuous water droplets). The main parts where leakage occurs are the seal between the plate and the plate, the part of the second sealing leakage groove of the plate, and the inner side of the end plate and the compression plate. The main feature of the fluid flow is that the medium on the higher pressure side is strung into the medium on the lower pressure side, and pressure and temperature abnormalities will occur in the system. If the medium is corrosive, it may also cause corrosion of other equipment in the pipeline. Liquid leakage usually occurs in the diversion area or the secondary sealing area. Large pressure drop The inlet and outlet pressure drop of the medium 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. In order not to affect the normal use of the plate heat exchanger, when the above three situations occur, it is basically necessary to replace the gasket of the plate heat exchanger in time.
