Water source requirements of heat exchanger
Sep 25, 2020

Speaking of heat exchanger a lot of friends have some understanding of it, but today small make up want to introduce to you about the knowledge of water requirements of heat exchanger, interested friends go to have a look.


Impurities dissolved in water in ionic or molecular state are harmful. There are many calcium salts in water which are the main components of heat exchanger fouling. This kind of salt is a kind of hard and crystallized scale with loose structure and little adhesion. It is a kind of relatively soft sludge, which has fluidity when separated from water.


Two, the harm of dissolved oxygen gas. There are many reasons for the corrosion of heat exchangers, but the most serious corrosion, the fastest or oxygen. Local corrosion occurs when the corrosion is concentrated on certain parts of the metal surface. The local corrosion speed is fast and easy to rust through. Pit corrosion is a common local corrosion in heat exchangers.


Third, the impurity in the colloidal state is harmful to the heat exchanger. Colloids are mainly iron compounds, microorganisms, dirt, clay and so on. The water quality requirement of heat exchanger fluid is very important. In the operation management, we should pay more attention to it and provide some necessary anti-scale and anti-corrosion equipment to prolong the service life of the equipment.
