How to avoid corrosion of refrigerated rcirculator?

If the acidity in the environment is high, it is necessary to stop the comprehensive cleaning of the FL +5°C ~ +35°Cウォーターチラー.

It is suggested that enterprises should ensure that the refrigerated circulator is in a medium operating environment, and will not affect the service life of the refrigerated circulator due to high acidity, resulting in a large number of defects.

Adhering to the acid-base balance of the environment will help to improve the operation efficiency of the refrigeration circulator and reduce the range of problems affecting the refrigeration circulator.

In order to prevent the appearance of corrosive problems, it is suggested that enterprises should regularly stop comprehensive cleaning of refrigeration equipment for cold storage projects.

Even in the environment with high acidity, it is only necessary to clean the refrigeration equipment regularly, so acidic substances will not form the problem of the refrigeration equipment.

The normal operation of the refrigeration circulator will not be affected as long as the external and internal acid-base can be balanced.

It is essential to provide a suitable operating environment. If the refrigerated circulator is in a bad environment, it will inevitably be affected by various corrosive substances.

In order to better complete the whole operation process, we can adhere to the acid-base matching of the operating environment with the operation specifications of the equipment, and can prevent various acidic substances from affecting the operation of the refrigeration equipment.

Prevent electrochemical corrosion

① Prevent pitting

(1) The main consideration is to reduce the content of harmful impurities and add appropriate alloying elements to improve the pitting resistance of the material.

(2) In terms of architecture design, attention should be paid to eliminating blind spots and preventing the concentration of harmful substances.

(3) Reduce the concentration of halide ions in the medium as much as possible. After installing and using the water cooler, what the circulating water system can do is to reduce the concentration of harmful ions as much as possible.

The concentration of chromium ion is 0 ≤ 200mg/L according to the factory control index. The circulating water equipment is easy to scale, and the bactericidal and algal agent is specially prepared for bacteria and algae, which can quickly eliminate bacteria and algae.

② Prevent crevice corrosion

(1) In the architecture design, avoid cracks and geometric structures that may cause surface precipitation.

(2) When voids cannot be avoided, solid fillers can be used to fill the voids.

(3) The service life of the equipment can be extended when the material with crack corrosion resistance is selected.

(4) Select cathodic protection.
