Daily maintenance of finned tubes
Daily maintenance of finned tubes? Appropriate maintenance methods will have a multiplier effect on the later use of finned tubes. Regular maintenance can reduce the cost and time of replacing finned tubes.
Daily maintenance of finned tubes?
1. Regularly check whether each finned tube is complete, whether there are deposits, coking, water rust and other scales attached, and clean them immediately. At the same time, it is also necessary to check whether the adhesion between each finned tube and the rubber gasket is tight, and whether the rubber gasket itself is intact, so as to avoid leakage caused by debonding and damage of the rubber gasket.
2. The compression nuts and upper and lower guide rods of the plate heat exchanger should be lubricated frequently with lubricating grease.

3. Each instrument adjustment should be handled by a dedicated person, and the operation and maintenance procedures should be strictly followed.
4. When the rubber gasket needs to be replaced or the degummed part needs to be repaired, the fin tube needs to be removed and placed on the table, the old gasket needs to be removed, or the glue traces in the groove of the fin tube at the degummed part need to be rubbed with fine sandpaper, and then the oil traces in the groove need to be wiped off with solvents such as carbon tetrachloride or trichloroethylene, and then the back of the new rubber gasket needs to be rubbed with fine sandpaper, and the oil traces need to be wiped off with carbon tetrachloride or trichloroethylene solvents. Then apply a thin layer of glue on the groove and the back of the rubber gasket, wait for it to dry slightly, so that it does not stick to the fingers, but is still sticky. The rubber gasket is embedded in the groove, flattened around, and a layer of talcum powder is applied. Then the fin tube is installed on the equipment frame and gently clamped. It can be put into production and use at intervals according to the glue instructions.
5. Each time you re-tighten the fin tube, pay attention to the scale position of the last tightening, and do not over-press the rubber gasket, which will reduce the service life of the gasket.
6. When replacing the fin tube rubber gasket, you must update this section to avoid uneven gaps between the pieces, which will affect the heat transfer effect.
