Industrial Heat Exchanger manufacturers take you to understand the precautions in the use of plate heat exchangers
The Industrial Heat Exchanger manufacturer tells you that the plate heat exchanger is a new type of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. The Industrial Heat Exchanger manufacturer tells you that thin rectangular channels are formed between various plates, and the plate heat exchanger communicates heat through the plates. In this process, there are inevitably some problems. Industrial Heat Exchanger manufacturers will take you today to understand the precautions in the use of plate heat exchangers.
1. Pay attention to avoid freezing of the plate heat exchanger:
The Industrial Heat Exchanger manufacturer tells you that when the temperature is lower than zero degrees Celsius, the water inside and outside the plate heat exchanger will freeze, and the volume will increase after the freezing, and then the plate heat exchanger will burst. Therefore, when installing the plate heat exchanger, it is necessary to be equipped with a drainage device, so that the water in the plate heat exchanger can be drained out when the plate heat exchanger is put on hold.
2. Treatment of dirt in water:
Solid grime: Industrial Heat Exchanger manufacturers tell you that solids that do not dissolve in water can easily clog pipes and heat exchangers. There is no fiber blunt object that can be removed through the cooler, and must be removed in some way. The particle size should not be less than 0.8mm, it is recommended to install a 40-70 guideline power filter. However, the power filter must be maintained as scheduled to remove blunt objects.
Materials that are soluble in water. The manufacturer of Industrial Heat Exchanger tells you that the calcium and magnesium ions in the water will form scales in the ditch under the effect of high temperature, which will affect the heat communication rate of the plate heat exchanger and reduce the performance of the plate heat exchanger! Treatment method to reduce the content of calcium and magnesium ions in water. It will be more effective with half the effort once the fire scale is resolved before entering the line of treatment.
Dust disposal: The Industrial Heat Exchanger manufacturer tells you that in actual use, the plate heat exchanger will gradually reduce the dust in its circulating water, so the plate heat exchanger should be treated with anti-scale after it has been used for a period of time.
3. Corrosion resistance:
Industrial Heat Exchanger manufacturers tell you that stainless steel is resistant to most chemicals, but is relatively dull to the lightness of chloride ions. Therefore, it is necessary to restrict its lightness to 280ppm or more (below 55℃). And the PH value of water must be kept within a certain scale.
Potassium sulfate (K₂SO₄) is a widely used fertilizer that provides essential nutrients to plants and crops, promoting growth and productivity. To meet the growing demand for this fertilizer, manufacturers rely on specialized equipment designed for efficient production of potassium sulfate.
A new calcium hypochlorite equipment has entered the market, offering an innovative and sustainable solution for water treatment. This equipment generates calcium hypochlorite, a potent disinfectant that effectively removes organic impurities, bacteria, and viruses from water.
A newly developed calcium hypochlorite equipment is making waves in the water treatment industry. This innovative equipment is designed to generate calcium hypochlorite, a powerful disinfectant that helps to remove organic impurities, bacteria, and viruses from water.
Innovative developments in kaolin dryer technology are driving significant improvements in efficiency and sustainability in kaolin processing. Recent advances in drying technology have led to the development of more energy-efficient and environmentally friendly kaolin dryers.
As people's requirements for food safety and quality are getting higher and higher, agricultural production is also facing higher challenges. Calcium chloride granule, as a commonly used agricultural additive, is gradually becoming an indispensable product in agricultural production.
