How to maintain the equipment applied with finned tubes

How to maintain the equipment applied with finned tubes?

1. Check each fin tube to see if they are in good condition and do timely cleaning when they are with sediments,coking, incrustation layer and other scale attached.Meantime, check the rubber gasket itself if good and then the adhesion between fin tube and rubber gasket if tightly or not, to avoid the leakage caused by rubber gasket degumming and damage.

2. Compress the nuts and guide bars upper and lower on plate heat exchanger and lubricate it with grease regularly.

3. Each instrument should be responsible by specialist, operate and maintain strictly according to standard.

4. When need to change the rubber gasket or repair the degumming part, need to get off the finned tube, on the table, the old washer will be removed, or in the degumming finned tube groove glue sites use sandpaper to clean, with carbon tetrachloride or solvent such as trichloroethylene rub oil inside the groove, the new rubber gasket brush hair back with fine sand paper, also with carbon tetrachloride or trichloroethylene solvent wipe grease stain. Then in the grooves and rubber gasket are apply a thin layer of glue on the back, to do a bit, to not sticky fingers, but it is still sticky for degrees, the rubber washer embedded groove, flatten all round, apply a layer of talcum powder, then finned tube fitted with equipment frame clamping gently. According to the instructions of the glue, the royal family can go into production for a period of time. 

5. Each time the fin tubes are repressed, Pay attention to the calibration position of the last compression, do not overpressure the rubber gasket, so as to reduce the gasket service life.

6. When replacing the rubber gasket of finned tube, the whole section should be updated to avoid the uneven gap and influence the heat transfer effect.
