Plate heat exchanger is also known as plate heat exchanger. In addition to the maintenance under special circumstances, regular maintenance should also be carried out. As plate heat exchanger is easy to disassemble and repair, it generally does not need special tools and equipment. Different methods can be adopted according to different situations. If there is no leakage in the equipment, but the heat transfer system K is decreased, a closed-circuit system can be used to pump the descaling solution into the equipment for several hours instead of dismantling the heat exchanger. There is no such condition on site, and when the equipment is disassembled or the scaling is not serious, the plate can be directly washed with water without removing the plate, and the soft brush can be used at the same time. Now let's understand the maintenance steps in detail!
