Corrosion Causes of Industrial Chillers

With the development of science and technology, more and more industrial chillers are used in various fields of industry, which have made due contributions to industrial production and product quality improvement.

And the industrial chiller has been running for a long time, and some problems will inevitably occur, among which the corrosion phenomenon is one of the common problems of the chiller.

In order to avoid the corrosion of the chiller and prolong the service life, we will discuss several reasons for the corrosion of the chiller for the enterprise below, and then take corresponding measures to avoid the corrosion of the chiller and affect the production of the enterprise.

1. Unreasonable engineering construction or design and installation cause the chiller to corrode.

Some users should have encountered it. For example, after purchasing an industrial chiller, especially an ordinary chiller, it has not been treated with any anti-corrosion, anti-rust, etc., and is directly placed in an outdoor environment. Shell corroded.

2. Corrosion caused by incorrect installation or abnormal operation of the water processor.

The cooling water pipeline is the channel for the cooling water circulation of the water-cooled chiller. The water quality determines whether there is scale and corrosion in the system pipeline. If the water processor is not installed properly or works abnormally, corrosion will occur.

3. Most of the decontamination devices are Y-type filters, which are weak in filtering small impurities.

Y-type filter is easy to install and clean. It can coarsely filter mechanical impurities, iron filings, and sand particles, but cannot filter fine impurities. Mud and other impurities.

4. There is no quick drain valve installed in the chilled water system

The quick blowdown valve is a blowdown valve used in the chilled water system. It has the characteristics of simple structure, good sealing performance, small size and light weight. It is especially suitable for regular blowdown of the system, and has the advantages of corrosion resistance, impact resistance and long service life. .

At present, many industrial chiller end plates are not installed with quick drain valves. It will cause the corrosion of the system pipeline. In the usual use of the chiller, the blowdown valve should be opened and closed 3 times a week to facilitate the system blowdown.

5. The water supply pipe of the cooling system is not installed with a water meter

For the treatment of water quality in the cooling system, chemicals and bacterial agents are generally used to kill and manage internal fungi, microorganisms, and various types of dirt.

And if there is no water meter for measurement, it will cause inaccurate dosage, resulting in corrosion of the system pipeline in the later stage.

6. Acid and alkaline gases in the environment cause corrosion to the surface of the equipment

In the production of the factory, it is inevitable that there will be special gases, such as the flow of acid and alkali gases, which will cause harm to the surface of the equipment. Therefore, when choosing a chiller in such an environment, you should explain it to professionals in advance. Explosion-proof and corrosion-resistant pipes are preferred for electric control cabinets or evaporator pipes. To avoid subsequent corrosion loss.

With the development of the industry and the continuous application of new materials and new processes, the use scenarios of industrial chillers have become diverse, and the probability of equipment corrosion has also increased invisibly.
