What are the tips for maintaining industrial heat exchangers?
Nov 24, 2018

Industrial heat exchangers are an important part of heat exchange technology in process industry equipment. After long-term operation, the surface of the plate will produce different scales or deposits, which will reduce heat transfer efficiency and increase flow resistance. Therefore, the equipment should be based on water quality. The actual conditions such as the temperature medium characteristics should be periodically disassembled to check and remove the dirt. The sodium carbonate solution can be used to clean the plate with a brown brush. For a small amount of sediment deposition in the channel or the precipitation of debris in the medium, it can also be used in the short-term running direction. Reverse running, in order to punch out part of the sediment, also has a good effect.

 

The damaged plates in industrial heat exchangers should be replaced in time. When assembling the equipment, the plates and gaskets should be kept clean, the plates should be placed neatly, and the plates should be assembled according to the product assembly form. When tightening, the stud should be pressed tightly, and the force should be even, to prevent the individual studs from being too tight to damage the stud and the plate.

 

The aging gasket in the industrial heat exchanger should be replaced; when the plate and the gasket are detached, the plate sealing groove adhesive is washed away with a thinner material, and after cleaning, it is coated in the sealing groove with a suitable adhesive. , re-bonding firmly. When the industrial heat exchanger is stopped in winter, the medium inside the equipment should be drained to prevent freezing of the equipment, and other antifreeze measures can be used.

 

On the nameplate of industrial heat exchangers with this function, the maximum and minimum stresses are generally given. For new sets, the connection should be fixed with the minimum allowable stress. Depending on the number of heat exchanger sheets per unit, the tightening force of the heat exchanger can be adjusted one or more times.http://www.wxlsshzb.com/
