Introduction Of The Gaskets And Leaks Of Plate Heat Exchangers

  In order to solve the dripping phenomenon caused by the aging of the gasket, the plate heat exchanger allows the sealing performance of the heat Introduction of the gaskets and leaks of plate heat exchangersexchanger to be adjusted. It is to tighten the bolts of the combined plate heat exchanger again, and adjust the pressing force of the elastic seals between the heat exchangers to solve the problem of dripping. The maximum and minimum stresses are generally given on the nameplate of the heat exchanger.

  The main parts of the external leakage of the plate heat exchanger are the seal between the plate and the plate, the second sealing leakage groove of the plate and the end plate and the inner side of the compression plate.The main parts of the external leakage of the plate heat exchanger are the seal between the plate and the plate, the second sealing leakage groove of the plate, and the end plate and the inner side of the compression plate. (1) The pressure drop is large. The pressure drop at the inlet and outlet of the medium exceeds the design requirements, and even many times higher than the design value, which seriously affects the system's requirements for flow and temperature. In a heating system, if the hot-side pressure drop is too large, the primary flow rate will be seriously insufficient (the heat source is insufficient, resulting in the secondary-side outlet temperature not meeting the requirements).(2) The main characteristic of liquid stringing is that the medium on the higher pressure side is stringed into the medium on the lower pressure side, and the system will have abnormal pressure and temperature.If the medium is corrosive, it may also cause corrosion of other equipment in the pipeline.Streaking usually occurs at the diversion area or at the second sealed area. (3) The heating temperature cannot meet the requirements. The main feature is that the outlet temperature is too low to meet the design requirements.
