Heat Exchanger Unit It is a device that transfers part of the heat from a hot fluid to a cold fluid. That is, water or other medium is installed in a large closed container, and there are pipes passing through the container. Let the hot water flow through Heat Exchanger Unit the pipes. Due to Heat Exchanger Unit the temperature difference between the hot water inside and the cold water in the container, heat exchange, that is, thermal equilibrium, will be formed. The heat of a high-temperature object always transfers to a low-temperature object, thus transferring Heat Exchanger Unit the heat of the water in the pipe to the cold water in the container. The heat exchanger is also called a heat exchanger.
Heat Exchanger Unit Cleaning is usually carried out in a special cleaning site, but due to equipment maintenance, the downtime is usually short, Heat Exchanger Unit cleaning is time-consuming and laborious, and the cost is high. The current maintenance and modification are carried out in the device, which is convenient and fast. 。 Heat Exchanger Unit Safety and site hygiene should be noted during cleaning. ， After cleaning, use the instrument wind to Heat Exchanger Unit 、 blow dry the surface and inside of the tube bundle to prevent rusting and prolong the carbon steel pipes Heat Exchanger Unit service life of the tube bundle.
Heat Exchanger Unit Four major steps of cleaning:
1、 Heat Exchanger Unit Descaling cleaning
Add the prepared descaling cleaning agent proportionally to the circulating water in the cleaning tank for cleaning and descaling. Determine the Heat Exchanger Unit cleaning cycle time and the amount of agent added according to the amount of scale. After confirming that all scale has been cleaned, proceed to the next cleaning procedure.
2、 Clean water cleaning
Connect the cleaning Heat Exchanger Unit After connecting, use clean water for circulating cleaning 10 minutes, check the system status for leaks, and remove the floating rust at the same time.
3、 Corrosion removal cleaning
Proportionally in Heat Exchanger Unit Add surface stripping agent and release agent to the circulating water in the cleaning tank, and circulate and clean 20 minutes to separate the scale and the components to be cleaned. At the same time, for those without scaling Heat Exchanger Unit objects are treated with anti-corrosion to prevent the cleaning agent from corroding the cleaning components during descaling cleaning.
4、 Passivation and plating treatment
Add passivation and plating agent to the cleaning system for passivation and plating treatment to prevent Heat Exchanger Unit corrosion of pipelines and components and the generation of new rust.
