Features of marine plate heat exchanger

24-02-2021

The tube plates at both ends of the plate heat exchanger are not connected to the shell at one end, and can expand and contract freely along the length of the tube. When the thermal expansion of the shell and the bundle of the marine plate heat exchanger is inconsistent, the tube bundle and the floating head can be freely expanded and contracted in the shell. This structure can eliminate the thermal stress. During the cleaning and maintenance of the marine plate heat exchanger, the entire bundle can be taken out of the shell. Despite the complex structure and high cost, marine plate heat exchangers are widely used.

What should I do if effect of  theClosed circulating water cooling heat exchanger  is low? When the closed circulating water cooler is in use, sometimes the effect is not obvious. That is because the heat exchange efficiency of the closed circulating water cooler is too low. What is the cause? I have summarized for everyone, disassemble the closed circulating water cooler to clean the interior; disassemble the interface part to clean the outlet and rearrange the heat exchanger plates; replace heat exchanger gasket ; re-select or adjust the working conditions; eliminate non- Condensate gas; disassemble the closed circulating water cooler and clean the plate to change the plate arrangement; change the flow rate or requirements; remove the gas and replace the condensate discharge valve or the air pump to replace the steam control valve; modify the system.
