Low noise Huatal cooling tower factory price for water cooling

High-frequency quenching machine is a professional equipment for metal heat treatment. It mainly uses the heat generated by high-frequency current passing through the inductor to quickly heat the workpiece and then cool it to achieve the purpose of changing the material properties of the workpiece. The cooling process after quenching is the key link to ensure that the material properties reach the expected goals.As a highly efficient heat exchange equipment, closed cooling towers can play an important role in many industrial fields, including cooling and circulating water systems in the metallurgical industry. In the application of high-frequency quenching machine tools, closed cooling towers are mainly used to cool the internal components of high-frequency heating power supplies to ensure the stable operation of the machine tools and the quenching quality.The main advantages of closed cooling towers in high-frequency quenching machine tools:1 Closed circulation does not pollute: The closed cooling tower adopts a closed circulation system, and the circulating medium (such as pure water) flows in a closed pipe, avoiding the problems of water pollution and blockage in traditional open cooling towers. This is especially important for high-frequency quenching machine tools, because the quenching process has high requirements for water quality, and the closed circulation can keep the water quality clean and stable.2. Constant pressure frequency conversion technology: Modern closed cooling towers often use constant pressure frequency conversion technology, which can adjust the cooling water volume and cooling effect according to actual needs, thereby achieving energy saving and consumption reduction.For high-frequency quenching machine tools, this helps to reduce operating costs and improve production efficiency.3 Good cooling effect: The closed cooling tower takes away the heat in the circulating medium and dissipates it into the atmosphere by spraying water and air heat exchange, thereby achieving efficient cooling.This cooling method can quickly reduce the temperature of the internal components of the high-frequency heating power supply and ensure the stable operation of the machine tool in a high-temperature environment.4 Easy to maintain: The structure of the closed cooling tower is relatively simple, and due to the use of a closed circulation system, the generation of scale and impurities is reduced, and the difficulty and cost of maintenance are reduced.This is of great significance for the long-term use of high-frequency quenching machine tools.The closed cooling tower, with its closed circulation, constant pressure frequency conversion, good cooling effect and easy maintenance, provides a strong guarantee for the stable operation and efficient production of high-frequency quenching machine tools.The above is the relevant content of the closed cooling tower system for high-frequency quenching machine tools.

Can the cooling tower not produce white fog when it is running in winter?A closed cooling tower is a device that exchanges heat through heat transfer. When it is running in winter, due to the low ambient temperature, when the gas is discharged from the outside of the tower, the gas temperature will be lower than the dew point temperature, which is easy to produce white fog. As the people's requirements for environmental protection are getting higher and higher, it is required that the cooling tower should not produce white fog when it is running in winter.After many tests, Jiangsu Huata has developed a cooling tower with a combined dew removal and exhaust system, thereby overcoming the defects in the above-mentioned prior art and obtaining a patent.The water vapor fogging point is 0℃ temperature and 100% humidity. When the external environment temperature is higher than 0℃, the hot and humid air in the cooling tower needs to be cooled by the hot air main fan 21 before being discharged. At this time, the discharge will not produce white fog; when the external environment temperature is lower than 0℃ and the humidity of the hot and humid air in the cooling tower is less than 80%, it has not reached the level of fogging and frosting. Because the external environment temperature is low, it is only necessary to turn on the cold air auxiliary fan 22 to discharge the hot and humid air in the cooling tower (it is wasteful to turn on the hot air main fan 21 at this time); when the external temperature is lower than 0℃ and the humidity of the hot and humid air in the cooling tower is greater than 80%, when the humidity of the hot and humid air is slightly higher, the water vapor is easy to reach the fogging and frosting point. At this time, the hot air main fan 21 is turned on, and the cold air auxiliary fan 22 is turned on and reversed to mix the hot and humid air generated by the cooling tower with the dry and cold air of the external environment, so that the humidity of the hot and humid air in the cooling tower can be reduced to below 80%, and then no white fog will be generated when it is discharged from the induced draft duct 24.The opening and closing of the hot air main fan 21 and the cold air auxiliary fan 22 are mainly connected to the electrical appliances of the combined defogging and exhaust system 2 of the cooling tower through the PLC controller 3. After the temperature sensor 25 and the humidity sensor 26 transmit the electrical signals to the PLC controller 3, the PLC controller 3 converts the electrical signals into mechanical signals of the hot air main fan 21 and the cold air auxiliary fan 22, thereby realizing the opening and closing of the hot air main fan 21 and the cold air auxiliary fan 22.The cooling tower is equipped with a combined defogging and exhaust system 2, and the operation of the combined defogging and exhaust system 2 is controlled by the PLC controller 3. On the one hand, even in the cold winter, when the humidity of the outside air is high, the combined action of the hot air main fan 21 and the cold air auxiliary fan 22 can also avoid the phenomenon of white dew in the cooling tower, and the operation is more environmentally friendly. On the other hand, when the outside temperature is low and the humidity of the hot and humid air in the tower is not high, the cold air auxiliary fan 22 can be turned on for exhaust, which is energy-saving and environmentally friendly: the induced draft duct 24 is a shaped structure and the air outlet is downward, which is more conducive to the discharge of the gas generated by the cooling tower.

The anti freezing work of a closed cooling tower in winter is crucial, which not only affects the normal operation of the cooling tower, but also directly affects the stability and service life of the entire cooling system. Therefore, we need to take a series of effective measures to ensure that the closed cooling tower can operate safely and stably in winter.Firstly, we need to strengthen the insulation work of the cooling tower. In winter, when the temperature drops sharply, the water inside the cooling tower is prone to freezing, causing damage to pipelines and equipment. Therefore, we need to insulate the exterior and interior of the cooling tower, wrap the pipes and equipment with insulation materials, reduce heat loss, and maintain stable water temperature.Secondly, we need to regularly check the operating status of the cooling tower. In winter, the operation status of cooling towers may be affected by various factors, such as low temperature, wind and snow. Therefore, we need to regularly check the various parameters of the cooling tower, such as water temperature, water level, flow rate, etc., to ensure that they are within the normal range. At the same time, we also need to inspect various components of the cooling tower, such as water pumps, fans, etc., to ensure that they can work properly.In addition, we can also take some auxiliary measures to prevent the closed cooling tower from icing. For example, installing wind deflectors at the inlet of the cooling tower to reduce the entry of cold air; Install a heater at the bottom of the cooling tower to increase water temperature and prevent icing; Install a drain valve at the outlet of the cooling tower to regularly drain accumulated water and avoid icing.Finally, we need to strengthen the maintenance and upkeep of the cooling water tower. After the end of winter, we need to conduct a comprehensive inspection and maintenance of the cooling tower, replace damaged parts, clean pipelines and equipment, and ensure that the cooling tower can maintain good performance in the next year of use.In summary, the anti freezing work of closed cooling towers in winter requires us to start from multiple aspects and take various measures to ensure the safe and stable operation of the cooling towers. Only in this way can we provide strong guarantees for the stability and service life of the entire cooling system.

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.
