1. Regularly check whether each fin tube is perfect, whether there are deposits, coking, scales, etc., and clean it immediately. At the same time, it is necessary to check whether the adhesion of each fin tube and the rubber gasket is tight, and whether the rubber gasket itself is intact, so as to avoid leakage caused by degumming and damage of the rubber gasket. 2. The compression nut and upper and lower guide rods of the plate heat exchanger should be frequently lubricated with lubricating grease. 3. Special personnel should be responsible for the adjustment of each instrument, and strictly implement the operating procedures for operation and maintenance. 4. When you need to replace the rubber gasket or repair the degummed part, you need to remove the fin tube, put it on the table, remove the old gasket, or use fine sandpaper for the glue traces in the groove of the fin tube at the degumming place Wipe it off, then use a solvent such as carbon tetrachloride or trichloroethylene to wipe off the oil stains in the groove, and then wipe the back of the new rubber gasket with fine sandpaper, and also use carbon tetrachloride or trichloroethylene solvent Wipe off the oil stains. Then apply a thin layer of glue on both the groove and the back of the rubber gasket, and let it dry for a while, so as not to stick to the fingers, but still sticky, insert the rubber gasket into the groove, flatten it around, and apply a layer of talcum powder , Then install the finned tube on the equipment frame and gently clamp it. According to the requirements of the glue manual, it can be put into production and use at intervals. 5. Every time the fin tube is re-tightened, pay attention to the position of the scale during the last pressing, and do not over-press the rubber gasket, which may reduce the service life of the gasket. 6. When replacing the rubber gasket of the fin tube, all the sections must be updated to avoid uneven gap between the fins and affect the heat transfer effect. The plate heat exchanger of the fin tube needs regular lubrication and maintenance. Its various instruments and instruments need to be managed by a special person in charge. During the operation, the finned tube must be operated in accordance with the requirements of the specification. When the finned tube needs to be compressed, special attention must be paid to the position of the scale after the last compression. , Do not press the rubber gasket of the fin tube too tightly when pressing it again, so as not to shorten the service life of the rubber gasket.
