Low noise factory price for water cooling

Closed cooling towers are indispensable equipment in industrial cooling systems. They provide effective heat exchange solutions through a closed circulation system. This type of equipment is mainly composed of the following key components:1. Heat exchange coil: This is the core part of the closed cooling tower, responsible for transferring the heat of the medium (such as oil or water) that needs to be cooled to the environment. The coil is usually made of corrosion-resistant materials to cope with chemical corrosion in various industrial environments.2. Fan: The function of the fan is to drive air flow and accelerate the dissipation of heat. An efficient fan can ensure good air flow through the heat exchange coil, thereby improving cooling efficiency.3. Casing: The casing protects the internal components from the influence of the external environment, such as weather changes, dust, etc. The casing is usually made of carbon steel anti-corrosion material or fiberglass to ensure long-term durability and safety.4. Spray water pump: The spray water pump transports desalted water to the upper part of the closed cooling tower, increases the contact area between water and air through spraying, and improves cooling efficiency.5. Internal filler: The filler is used to increase the contact area between water and air and optimize the heat exchange process. Good filler design can significantly improve the cooling effect.In summary, these components work together to ensure that the closed cooling tower can operate efficiently and provide good cooling solutions for various industrial applications. Proper maintenance and regular inspection of these components are important to maintain the good performance of the equipment.

The air inlet of various types of closed cooling towers may freeze. The air inlet of natural ventilation counterflow closed cooling towers usually freeze at the lower edge of the inner wall of the tower, or hang ice at the edge of the retaining eaves inside the tower. When it is light, it forms a thin ice curtain; and when it is serious, it freezes with column A of the tower to form an ice wall in the cross-flow cooling tower. There is ice in the inner edge of the louver of the inlet of the cross-flow cooling tower. Because the hard part of the cooling tower is water leakage, a large area of ice is formed on the side of the inlet column and the louver. The main reason for the intake icing is that the water around the packing of the cooling tower is too small, and a small amount of water flowing down the wall of the cooling tower stays in the intake for a long time. Upper edge or spout edge.If the heat load and water quantity of the whole tower is too small, the bottom of the pouring water packing of the whole tower will hang ice; Some use zoned water distribution cooling tower, because of uneven water distribution, will make part of the packing frozen. When the casting density is small, the cold air will invade first. In other areas with low watering density, it is easy to form freezing damage to plums, such as water tank blockage and damage. If the nozzle is blocked and the water tray falls off, it is easy to cause local freezing damage. If the local water of the pouring filler is too small or the pouring filler column is close to the air inlet, it is easy to cause the packing supporting beam column and part of the packing to freeze.An ice cone is formed on the inner and outer edges of the rigid ring at the top of the cooling tower. Due to the accumulation of water vapor, natural ventilation is carried out. In the mechanical ventilation cooling tower, the effect of the secondary tower part of the dehydrator is poor. With the air out of the tower, water drops fly out of the tower and fall on the platform on the top of the tower and the exhaust pipe of the fan, causing ice. The high efficiency dehydrator and the double wave dehydrator installed in the packing high wind speed area can eliminate the floating drops and solve the icing problem on the top of the tower.Because water separators are not installed or are ineffective, large drops of water fall on the surrounding ground, or vortices at the air intakes carry some of the droplets out of the tower and onto the ground. When multiple grilles in cooling towers are ventilated mechanically, some grilles will not operate in winter. Water vapor from the running tower falls on the fan blades in the stopped tower and accumulates on the surface area of these blades, so it freezes. If the blade on the ice from melting, static, dynamic balance of the blade will be out of balance, serious when bow | fan vibration and damage of the tower structure.When cooling towers are out of service in winter, the water-filled circulation ditches, pressure lines and valves can freeze because the water does not flow and cannot be replenished. The lateral frost heave force caused by freezing can reach 0.2 ~ 0.3MPa, causing damage to the equipment.

I. Causes of scaling and blockage in the closed cooling tower:  1. The circulating water is blocked by scaling due to heat. In the process of production and operation, the circulating water is heated and scaling, which reduces the heat transfer efficiency.  2. Impurities entering the pipe network will cause blockage.  3. The inner wall of the pipeline rusts, forming rust mud and causing the blockage.II. Hazards of scaling and corrosion to cooling and heat exchange system:  1. Significant increase in energy consumption and operating costs.  2. The working efficiency of the system is reduced, affecting the heating.  3. Shorten the service life of the equipment. Scaling and slime will seriously affect the normal operation of the system. Scaling and microbial slime are the main factors affecting the normal operation of the cooling system, which have a great impact on the normal operation and cost operation of the heating system. Therefore, regular cleaning is required. The following purposes can be achieved through cleaning:  1. Clean up the different scale, microbial sludge, and corrosion products in the circulating water system to ensure the normal operation of the system and high heating efficiency.  2. Reduce operating costs and greatly save energy. After cleaning, the power or heat consumption of the system can be reduced by about 20%, 6-30%.  3. Protect and improve the service life of enclosed cooling tower and pipeline equipment, while solving potential corrosion hazards.III. Heat exchanger cleaning method:Chemical pickling, including organic and inorganic acids, has long been used in heat exchangers. These chemical cleaning methods cannot solve the problem and cause serious damage to the equipment itself, the human body, and the environment. Based on the idea of reducing energy consumption and protecting the environment, it is suggested to use environmental cleaning agents regularly to clean the scale cleaning efficiency of the heat exchanger.This information is what we sharing with our friends today.

I. Glass fiber reinforced plastic housingGlass fiber reinforced plastic (FRP) is a kind of composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as the reinforcing material and synthetic resin as the matrix material. FRP, also known as glass fiber reinforced plastic, commonly known as: glass fiber reinforced plastic;    1. The corrosion resistance        Fiber reinforced plastics (FRP) is a good corrosion - resistant material. The closed cooling tower with FRP shell has good corrosion resistance to air, water and general concentration of acid, alkali, salt as well as various oils and solvents.    2. The insulation        FRP is also an excellent thermal insulation material, used to make the shell of closed cooling tower, can make the closed cooling tower has good thermal insulation performance.    3. The plasticity        As long as there is a mold, closed cooling tower products of various structures can be flexibly designed to meet the needs of the waist, so that the product can have a good integrity.The disadvantage is that aging is a common defect of plastic, FRP is no exception. Under the action of ultraviolet light, wind, sand, rain and snow, chemical media, mechanical stress, it is easy to lead to aging of cooling tower shell.II. Stainless SteelStainless steel is the abbreviation of acid-resistant stainless steel, resistance to air, steam, water and other weak corrosion medium or stainless steel known as stainless steel.    1. Heat resistance        Stainless steel material can work safely at -270°C-400°C temperature for a long time, regardless of high and low temperature, will not precipitate harmful substances, material performance is quite stable.    2. Corrosion resistance       The thin and dense chromium-rich oxide film on the surface gives the stainless steel casing excellent corrosion resistance in all kinds of water (including soft water), even in buried use.The disadvantage is that the production cost is high, the case of the same size is almost five to six times that of other materials, and the workmanship is also many locks, cutting and modeling need to confirm the process and machine equipment.III. Aluminum zinc alloy plating steel sheetAluminum zinc alloy plating steel sheet is an aluminized zinc alloy structure formed by solidification of 55% aluminum, 43% zinc and 2% silicon at 600°C. The overall structure is composed of aluminum, iron, silicon and zinc, forming a dense four-element crystal alloy.    1. Long service life        Aluminized zinc plate has strong corrosion resistance.    2. Heat resistance        The aluminized zinc plate has high thermal reflectivity and is suitable for roofing data. Aluminized zinc alloy steel plate has excellent heat resistance and can be used in high temperature environment above 315 degrees.    3. Corrosion resistance        The aluminized zinc plate has good adhesion with the paint film and can be directly sprayed or powdered without special pretreatment.The disadvantage is that if the galvanized layer has scratches or damage, it will be so difficult to corrode for a long time from the injured horse. When the work is selected, the process and machine foundation need to be fixed.IV. Magnesium aluminum zinc alloy plating steel sheetMagnesium aluminum zinc alloy plating belongs to the pre-plating treatment (and after zinc immersion relative), belongs to hot dip galvanizing (and electric galvanizing relative), the material is divided into magnesium aluminum zinc plate and magnesium aluminum zinc coil,- like magnesium aluminum zinc plate from the steel mill rolled to the hands of dealers, are the original volume, through this way can get magnesium aluminum zinc plate. The exact chemical elements (secret ingredients) are not disclosed. The disclosed chemical composition is 11 percent aluminum, 3 percent magnesium, and a very small amount about 0.5 percent silicon, and the rest zinc.    1. Performance advantages:        Other such as zinc, aluminum zinc, its corrosion resistance and rust resistance can not be compared with magnesium aluminum zinc, compared with galvanized sheet, the same coating, the service life of magnesium aluminum zinc is 10-20 times that of galvanized. This is very normal, the original intention of magnesium aluminum galvanized is to use the thinnest metal coating to achieve a thicker galvanized layer to achieve the effect. It is 3-5 times of aluminized zinc, and the product is positioned as the top material in the coating material.    2. Advantages of Specifications:       The maximum specification of galvanized sheet production is 2.0 (thickness direction) and only imported galvanized sheet, is not unwilling to produce, but can not produce, with such a process, the thickness increases, the difficulty coefficient of material coating is doubled; Aluminum zinc production of the maximum specification is 2.5 (thickness direction), most of the imported aluminum zinc and domestic Xindao, and magnesium aluminum zinc can produce specifications (thickness direction) can be up to 9.0mm, 0.27-9mm is the range within which it can be produced. Of course, the current spot specification in the Chinese market is 0.5-5.0, and the materials outside this range need to be ordered from the steel mill.
