What should be paid attention to in the use and maintenance of heat exchangers?Today we mainly analyze the heat exchanger in the use and maintenance of matters needing attentionDaily maintenance of heat exchangerIn daily operation, special attention should be paid to prevent the fluctuation of temperature and pressure.Cleaning of heat exchangerAfter a long time of operation, due to the corrosion, erosion, scaling, coking and other reasons of the medium, the internal and external surfaces of the pipe have different degrees of scaling, and even blockage.So in shutdown overhaul must carry on thorough cleaning, commonly used cleaning (sweep) method has wind sweep, wash, steam sweep, chemical wash and mechanical cleaning.But the traditional way of cleaning such as mechanical method (shave, brush) and high pressure water, chemical cleaning (acid) a lot of problems in the equipment when cleaning, such as: cannot completely remove scale and other sediments, acid corrosion on equipment form loopholes, residual acid to secondary material corrosion or corrosion under the scale, eventually led to the replacement equipment, in addition, the cleaning liquid is toxic, need a lot of money for wastewater treatment.But the use of high efficiency, environmental protection, safety, no corrosion, biodegradable fossetec environmental protection cleaning agent, not only cleaning effect is good and no corrosion to the equipment, can ensure the long-term use of the condenser.
