Heat exchanger in the use and maintenance should pay attention to what? Today, we mainly analyze the use of heat exchangers in the use and maintenance of the note
First, the daily maintenance of heat exchangers
Daily operation should pay special attention to prevent temperature and pressure fluctuations, first of all should ensure that the pressure stability, will not allow overpressure operation。
Second, the heat exchanger cleaning
Heat transfer equipment after a long period of operation, due to media corrosion, erosion, fouling, coking and other reasons, so that the pipe surface have different degrees of scaling, or even plug。 Therefore, in the shutdown maintenance must be thoroughly cleaned, commonly used cleaning (sweeping) methods sweep, washing, steam sweep, chemical cleaning and mechanical cleaning。
However, this traditional cleaning methods such as mechanical methods (scraping, brushing), high pressure water, chemical cleaning (pickling) and so on in the cleaning equipment, many problems: can not completely remove scale deposits, acid corrosion of equipment Loopholes, residual acid on the material resulting in secondary corrosion or scale corrosion, resulting in the replacement of equipment, in addition, cleaning waste toxic, requires a lot of money for wastewater treatment. But the use of efficient, environmentally friendly, safe, non-corrosive, biodegradable Fu World Tektronix environmental cleaning agent, not only the cleaning effect is good and there is no corrosion of the equipment to ensure the long-term use of the condenser.
