6 Major Reason of Industrial Chiller Corrosion
With the development of science and technology, more and more industrial chillers are used in various fields of industry, and they have played their due contributions to industrial production and improving product quality.
Industrial chiller is also a piece of mechanical equipment. After running for a long time, there will be some problems. Corrosion is one of the common phenomena of chiller.
In order to prevent the chiller from corrosion and prolong its service life, the following editor of Cadelli discusses several reasons for the corrosion of the chiller for industry friends, and then takes corresponding measures to avoid the corrosion of the chiller, which affects the production of our own enterprises.
1. Unreasonable engineering construction, design and installation cause corrosion.
Some industry friends should have encountered it. For example, after the purchase of industrial chillers, especially ordinary chillers, they have not undergone anti-corrosion, anti-rust and other process treatments. They are directly placed in an outdoor environment. After a long time, the shell will be caused by wind and sun. corrosion.
2, the water processor is installed incorrectly or works abnormally, causing corrosion.
Cooling water pipeline is the channel through which water-cooled chillers circulate the cooling water. The water quality determines whether the system pipeline has scale and rust. If the water processor is not installed in place or works abnormally, it will cause rust to occur.
3. The decontamination device is mostly Y-type filter, which is weak in filtering small impurities.
The Y-type filter is simple to install and clean. It can coarsely filter mechanical impurities, iron filings, and sand particles, but can not filter fine impurities. Therefore, the unit runs for a long time, and it is easy to cause condenser fouling and accumulation. Mud and other impurities.
4. There is no quick drain valve installed in the chilled water system
Quick blowdown valve is a blowdown valve used in refrigerators or chilled water systems. It features simple structure, good sealing, small size, and light weight. It is especially suitable for regular sewage discharge of the system. It has corrosion resistance, impact resistance and service life. Long and other advantages.
At present, many enterprises do not install quick blowdown valves at the end plates of industrial refrigerators. It will cause corrosion of the system pipes. In the usual use of the chiller, the drain valve should be opened and closed 3 times a week to facilitate the system to drain.
5. No water meter is installed in the water supply pipe of the cooling system
Cooling system generally uses medicaments and bacterial agents for the treatment of water quality to kill and manage internal fungi, microorganisms, various types of dirt, etc. When using medicaments, a certain amount of medicament should be allocated according to the amount of water supplemented and the amount of system water.
If there is no water meter to measure, it will cause inaccurate dosage and cause 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 factory production, there will inevitably be special gases, such as the flow of acid and alkaline gases, which will cause harm to the surface of the equipment. Therefore, if you choose a chiller in such an environment, you should explain to the professional in advance about the electric control cabinet or the evaporator pipe. Explosion-proof and corrosion-resistant pipelines are preferred. So as not to cause later corrosion loss.
With the development of industry and the continuous application of new materials and new processes, the use scenarios of industrial chillers have also become diverse, which invisibly increases the probability of equipment corrosion. For our industrial chiller equipment, real-time maintenance and customized maintenance are still the key to reducing corrosion and prolonging service life.
