The editor has summarized several points to note regarding the installation and use of plate heat exchangers. Let's take a look:
1. During disassembly and assembly, pay attention to the proper storage of the plates and avoid placing them carelessly. Because the thickness of the plate heat exchanger plates is only 0.5-0.7mm, accidental stepping on them can easily cause deformation, affecting the sealing performance.
2. Pay attention to cleaning the gasket groove. If there are impurities in the gasket groove, the gasket will not be properly seated, causing leakage. Also, check for damage or aging of the gasket and repair or replace it in time.
3. Install the plates in order, distinguishing between hot and cold media. Each plate should be installed with a 180-degree rotation. Also, prevent the plates from being worn or corroded; therefore, do not use steel brushes to brush the stainless steel surface, and avoid excessive use of acidic solvents for cleaning.
4. The operating environment requires dryness and ventilation, and the temperature should be kept below 40 degrees. When the heat exchanger is idle for a long time, loosen the clamping bolts beforehand and tighten them again before use. Plate heat exchangers should be transported upright.
5. Sealing gaskets should also be placed in a cool, dry environment. They can be placed in boxes or bags to prevent deformation due to compression or tension. Also, avoid contact with corrosive solvents such as acids and alkalis to prevent corrosion.
In summary, the above are the precautions for the installation and use of plate heat exchangers summarized by the heat exchanger manufacturer. It is especially important to note that in winter, when the temperature drops, it is necessary to prevent the water in the heat exchanger from freezing and causing structural damage to the heat exchanger. Therefore, the water inside should be drained promptly when the heat exchanger is not in use.
