With the development of science and technology, industrial chillers are increasingly used in various fields of industry, making due contributions to industrial production and improving product quality. The industrial chiller produced by the industrial chiller manufacturer is also a kind of mechanical equipment. There will be some problems during long-term operation. Among them, corrosion is one of the common phenomena of chillers. In order to avoid corrosion of the chiller and extend its service life, let’s discuss several causes of corrosion of the chiller, and then take corresponding measures to avoid corrosion of the chiller and affect the production of the company.

1. Corrosion caused by unreasonable engineering construction, design and installation. There should be friends in the industry who have encountered this. For example, after purchasing an industrial chiller from an industrial chiller manufacturer, especially an ordinary chiller, it is placed directly in the outdoor environment without anti-corrosion and anti-rust treatment. Over time, the shell is corroded by wind and sun.

2. Corrosion caused by incorrect installation or abnormal operation of the water processor. The cooling water pipeline is the channel for circulating cooling water in the water-cooled chiller. The water quality determines whether scaling and corrosion occur in the system pipeline. If the water processor is improperly installed or works abnormally, corrosion will occur.

3. Most of the decontamination devices designed by industrial chiller manufacturers are Y-type filters, which have weak ability to filter small impurities. Y-type filters are easy to install and clean. It can coarsely filter mechanical impurities, iron filings, and sand, but it cannot finely filter fine impurities. Therefore, long-term operation of the unit may easily cause scaling, mud accumulation and other impurities in the condenser.

4. There is no quick drain valve installed in the chilled water system. A quick drain valve is a drain valve used in refrigerators or chilled water systems. It has the characteristics of simple structure, good sealing performance, small size and light weight. It is especially suitable for regular sewage discharge in the system and has the advantages of corrosion resistance, impact resistance and long service life. At present, many companies do not have quick drain valves installed on the end plates of their industrial freezers. Will cause corrosion of system pipes. When using the chiller, the drain valve should be opened and closed three times a week to facilitate system drainage.

5. There is no water meter installed in the water supply pipeline of the cooling system. For water quality treatment, chemicals and microbial agents are generally used to kill and manage internal fungi, microorganisms, various dirt, etc. When using chemicals, a certain amount should be dispensed based on the water supply and system water volume. If water meters are not used for measurement, the dosage will be inaccurate, leading to later corrosion of the system pipelines.

6. Acidic and alkaline gases in the environment will corrode the surface of the equipment. The flow of special gases, such as acidic and alkaline gases, will inevitably cause harm to equipment surfaces in factory production. When choosing a chiller in such an environment, you should explain it to a professional in advance.

With the development of industry and the continuous application of new materials and new processes, the use scenarios of industrial chillers have become diversified, which inevitably increases the probability of equipment corrosion. Therefore, industrial chiller manufacturers recommend that industrial chillers still need to pay attention to maintenance and Regular maintenance.
