The fin tube maintenance has the following points: 1. Regularly check whether the fin tube cleaning 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 the 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. Every time the fin tube is re-tightened, pay attention to the position of the scale during the upper pressing, and do not over-press the rubber gasket, which may reduce the service life of the gasket. 5. When replacing the rubber gasket of the fin tube, all the sections must be updated to avoid uneven gaps between the fins and affect the heat transfer effect.
