Corrosion-resistant materials: The core components of the chiller, such as heat exchangers, pipes and shells, are usually made of high-alloy stainless steel (such as 316L stainless steel) or titanium alloy. These materials have excellent seawater corrosion resistance and can work stably for a long time in seawater with high salinity and chloride ion concentration.
Anti-corrosion coating: The shell and other exposed parts are usually coated with special anti-corrosion coatings, such as epoxy resin or polyurethane coatings. These coatings can effectively resist the erosion of seawater and extend the service life of the equipment.
2. Structural design
Anti-seawater penetration design: The chiller will take into account the risk of seawater penetration in its structural design and adopt a design with better sealing. For example, a double-layer sealing structure is used at key connections to prevent seawater from penetrating into the interior through gaps.
Drainage system: The unit is designed with an efficient drainage system to quickly drain the seawater that may penetrate and reduce the risk of corrosion.
3. Anti-corrosion treatment
Cathode protection: Cathodic protection technology is used on some key components, such as pipes and heat exchangers. By installing sacrificial anodes on the structure, metal corrosion can be effectively prevented.
Electrophoretic coating: Some components may be treated with electrophoretic coating technology for anti-corrosion. This coating has extremely strong adhesion and corrosion resistance.
4. Environmental adaptability
Salt spray test: During the design stage, the chiller will undergo a strict salt spray test to ensure that it can still maintain good anti-corrosion performance in a high salt spray environment.
Adapt to marine climate: The design of the chiller takes into account the variability of the marine climate, such as high temperature, high humidity and strong ultraviolet radiation. By using more weather-resistant materials and coatings, it can maintain stable operation in extreme environments.
5. Maintenance and monitoring
Regular inspection and maintenance: Chillers in a ship environment need to be inspected and maintained regularly, especially the condition of the anti-corrosion coating and the effectiveness of the cathodic protection system. Regular maintenance can detect and deal with potential corrosion problems in a timely manner.
Real-time monitoring: Some high-end chillers may be equipped with real-time monitoring systems that can monitor the corrosion status of key parts and warn of potential corrosion risks through data analysis.
Through the above measures, explosion-proof and anti-corrosion chillers can effectively cope with the challenges of seawater corrosion in ship environments. Its corrosion-resistant material selection, structural design, anti-corrosion treatment, environmental adaptability and regular maintenance jointly ensure the long-term and stable operation of the unit in harsh marine environments.
