Anode protection is to connect the protected heat exchanger to the anode of an external power supply, so that a passivation film Heat Exchangers FHC052 Exporters is formed on the metal surface to be protected. Satisfactory and economical anti-corrosion effect. When it is combined with a suitable cathode inhibitor, it can be used. 1. Chromate-zinc-hydrolyzed polyacrylamide: due to the dispersing effect of the cationic copolymer hydrolyzed polyacrylamide,
it can prevent or inhibit the generation of scale into dirt. Polyphosphate can be partially converted into orthophosphate, and they can also form large amounts with calcium.How should the plate heat exchanger be maintained and anticorrosive in its application? Knowing the causes of various corrosion of heat exchangers, and choosing anti-corrosion measures reasonably, can we achieve the purpose of efficient use of equipment
It is suitable for use in small refrigeration units.05mm/year. There are four corner holes on the plate for the passage of two heat transfer liquids. Some plate heat exchangers cannot be disassembled.5mm, and the maximum allowable corrosion degree is 0. The heat exchanger is difficult to clean, and it is easy to block and scale. Generally, air-conditioning equipment can be used for 15-20 years under normal maintenance and maintenance,
but the refrigeration host of some air-conditioning systems has only been used for a few years, that is, the plate heat exchanger of multiple hosts has been broken down, and the main reason is analyzed. Ordinary plate heat exchangers usually use alloy materials (304 or 316). Construction problems.
They are tightly arranged, It has high precision, small size, high heat exchange efficiency, space saving, and high requirements for the use environment. In addition, if the ‘Y’ filter is not cleaned up in time, there will still be small grit remaining in the circulating water, even if it is not harmful to the shell and tube heat exchanger, it will also have a wear hazard to the plate heat exchanger.
