With the air pollution becoming more and more serious, the requirement of industrial production for air treatment is also higher and higher. As a common ventilation equipment in industrial production, the improvement of working efficiency of air conditioning fan can reduce air pollution and improve the quality of environment to a great extent. However, the most important thing for the air conditioning fan to operate normally and to exert its effect is to ensure that it will not be damaged in the process of transportation. What should be paid attention to during the transportation of air conditioning fan? During the transportation of air conditioning fan, it is necessary to ensure that no water (such as rainwater) and other substances enter the air conditioning fan. Motor or other sensitive elements to avoid damage. At the time of delivery, check whether the air conditioning fan is damaged during transportation. During the inspection and before installation, please check that the air conditioning fan has delivered according to the specifications and drawings When forklift is used for loading and unloading in transportation, it is necessary to note that the fork must be located below the base of air conditioning fan to ensure that the structure and components of air conditioning fan will not be touched and damaged. When the crane is used for lifting, the hook can only be hung on the lifting ring of the air conditioner fan. Refer to the mark and warning mark. The fork used for is07000 must be located below the air conditioner fan base to reduce it as slowly as possible and place the air conditioner fan on a soft support. Impact, shaking and falling may lead to imbalance of air conditioning fan impeller. Provide imported air conditioning fan equipment, industrial air conditioning fan application solution and installation after-sales service Special attention shall be paid during the whole transportation process. If lifting is necessary, only approved lifting equipment can be used. Lifting operation shall be completed by professional personnel or professional lifting company. Strictly check the connection between the air conditioner fan and its device, pay attention to the center position, and do not stand under the lifting load. In the loading operation, please use a crane with enough bearing pressure or a container city suitable for loading and unloading, and designate a professional to finish or load the work. The safety of the transportation process is the basis to ensure that the air-conditioning fan can play a positive role in the delivery efficiency. If the air-conditioning fan is not well maintained and damaged, its work efficiency will inevitably be reduced. It is not conducive to the improvement of productivity, but also shortens its service life. Added to the maintenance cost of the user. Qi Neng air conditioning fan suggested that before transporting air conditioning and air conditioning fans, manufacturers should try to do the packaging work of air conditioning fans, use foam materials and so on to prevent air conditioning fans from running under turbulence. In order to standardize and unify the product packaging of the company and further improve the packaging quality, the company decided to change the old packaging box, namely the outer frame packaging box, into the inner frame packaging box. Our company has been using frame packing box for many years. However, it has been proved that although the old-fashioned packing case is simple and convenient, it is easy to warp, deform and even damage the packing case. This not only increases the cost of products, but also damages the interests of customers! In view of this situation, the design of the new inner frame packing box is as follows: 1. In view of the characteristics of air-conditioning fan products, such as heavy weight and large volume (up to several tons in weight and up to three or four meters in length), the inner frame type packing box is made up of a square frame made of strips of wood with a certain section in the interior, and the bracing is added in the middle. This greatly improves the strength of the packing box, as well as its anti-seismic, anti torsion, pressure resistance and stability; 2. The inner frame is located in the inner side of the packing box, which not only ensures the flatness of the outer surface of the packing box, facilitates the operation of the box surface, but also makes the whole packing box more beautiful, which is conducive to improving the brand image of the company's products; 3. Because the wooden packing box itself has no water-proof property, in the design of the new packing box, the design of linoleum is added on the cover plate for water-proof. 4. For the packing case of larger model products, bottom bracing is added to the base part to improve the bottom pressure resistance

With the diversification of user groups, the segmentation of air conditioning industry has become more mature. In many complex occasions, the traditional air-conditioning fan can not meet the needs of users. Therefore, in the face of different user groups, different specifications of air-conditioning fan units have been developed to adapt to the changes of the environment, but also for the current market demand. So what are the advantages of non-standard customized air conditioning fans? 1. Tailor to suit your needs and seek truth from facts. In depth communication with customers, fully understand the needs of users. If there is a need, you can conduct field investigation to collect the most accurate information before designing a reasonable and reliable scheme for users, and finally give customers a satisfactory product. 2. Diversified functions. According to the needs of customers, when customizing the air conditioning unit, you can flexibly add functional sections. Kaihong can add any functions that customers need, and ensure that all functions operate in coordination and achieve the best results. 3. Parts can be customized. Non standard customized air conditioning units can be used gradually, we can use whatever the customer needs. 4. Cost saving and customer maintenance cost saving. When making non-standard customization for kaihong air conditioner, we will carefully calculate a satisfactory price for customers, and maintain the quality of air conditioner unit on the basis of the satisfactory price. Reasonable use of resources to save customer costs colleagues for product maintenance to reserve enough convenient design space for later maintenance. 5. Reasonable utilization of mature technology to ensure product quality.

In recent years, China's fan industry has gradually become a large-scale industry, and the total domestic market has grown rapidly. Many powerful foreign manufacturers have begun to pay attention to the Chinese market, and the industrial war to compete for the domestic market as the core has also begun. Compared with international competitors, we are facing a crisis. The change of economic environment increases the cost pressure of enterprises This year, the impact of the decline of national economic growth on the fan industry will gradually appear, and the cost pressure of enterprise operation is bound to increase. The rise of workers' wages, the rise of RMB exchange rate, domestic inflation and the tightening of national currency policy all increase the seriousness of this problem. Overcapacity and serious homogenization of low-end products Unbalanced industrial structure. Although China's fan products cover more than 200 series and 2000 varieties, there are many kinds of products but not precise, overlapping layout and repeated investment are common. The mutual extrusion of raw materials, technology, capital, sales and other aspects aggravates the homogenization development trend of products; the inconspicuous product characteristics and inconspicuous competitive advantages make the fan enterprises develop in a self extending mode, which intensifies the polarization development trend of the fan industry in China. Basic technology research is not in place and common technology is backward In order to shorten the gap with the wind turbine manufacturing power, we must make a breakthrough in the R & D and manufacturing of major technologies and key components. However, the industry is currently facing the dilemma of lack of research and development of common technologies, many of which are eating the old roots. This is an important reason for the lack of innovation system and organization to study common, key and core technologies. Developed countries have put the research and development of common technology in the prominent position of industrial development, but the research and development of common technology in China has always lagged behind. In the future, we should gather the industry's advantageous resources, optimize the allocation, and speed up the construction of common technology research and development and innovation system with the support of relevant national departments, so as to achieve a real breakthrough in major key technologies in the industry. Product manufacturing mode needs to be upgraded At present, the biggest short board of fan products in China is poor reliability. The bad reliability of products brings about many bad results, first of all, the dissatisfaction of users, and second, the low profitability of enterprises. The cost of after-sales service has become a huge expense for Fan enterprises, and the poor reliability of products keeps the service cost high. The problem of poor reliability of domestic fan products can not be properly solved. The cap of Chinese fan products equal to low-end cheap products can not be removed, and national enterprises can only compete in the low-end market, forming a vicious circle. Improper competition in the industry begins to appear Improper industry internal competition. Under the trend of economic benefits, some slow developing fan manufacturers have no obvious advantages in industrial technology and product performance, so they start a vicious price war with the advantage of reducing product price from the conventional quality and quantity war. In order to seize the market, some enterprises even expand their market share at the expense of negative benefits. While seriously disrupting the market order, some regular manufacturers have to reduce the sales price of fans. Optimizing and improving the reliability of products involves all aspects, and improving the equipment manufacturing capacity is the first to bear the brunt. Sharp tools make good work. It can be said that whoever has excellent manufacturing capacity will win the market opportunity. To enhance the competitiveness of enterprises by technological development. Scientific and technological innovation, as the core value of an enterprise based on the market, is also the direct embodiment of the enterprise's development level and market competitiveness. With active technological innovation, it constantly improves the product grade and speeds up the product upgrading. In addition, as an important foundation for orderly development of China's fan industry, the unified and perfect market supervision mechanism is the first problem to be solved in this period.

According to the principle of converting kinetic energy into potential energy, centrifugal fan uses the high-speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy can be converted into potential energy. Fan is often used in industrial kilns, which is known as kiln fan. To some extent, centrifugal fan is a special machine after the improvement of common fan and its application in some aspects. Although this kind of centrifugal fan may be more diversified in function, it is similar to its parts maintenance in some infrastructures. One of them is the rotor that ensures the smooth operation of the fan. In fact, the rotor is a very small part, but it plays a very important role in the operation of the fan, and it cannot be ignored. In fact, the mechanism of the rotor is very simple, which is a tubular structure. Its main function is to fix the main rotating shaft, so that the fan can run smoothly. Compared with other fans, centrifugal fans have a little lower noise. The biggest disadvantage is that they are large in size. Because of their different structures, the power consumption of centrifugal fans is much higher than that of axial-flow fans under the same air volume and pressure, but the noise is relatively small. Therefore, axial-flow fans are mostly used in fire protection and ventilation. Usually, centrifugal fans are mostly used. In high-grade hotel buildings, centrifugal fans are preferred. Compared with other fans, centrifugal fans have more advantages in the combination of large air volume and large air pressure. When selecting the type, pay attention to whether the external dimension and structure are consistent with the equipment, so as to avoid the dimension difference of the fan's aperture, hole distance, thickness, etc. during the installation process, which makes it impossible to install and use. The internal structure and materials of the fan directly affect the performance and service life of the fan. In the sample test stage, the relevant performance or aging test shall be carried out for the fan to ensure that the fan operates under the required environmental conditions and ensure the working life of the fan. At the same time, select several more for testing. In the process of inquiry, it's better to have some contact with their engineers. At the same time, if you are in contact with others, you'd better be able to send your products using physical drawings, so that it is more convenient for others to choose your products. In the future, with the large-scale industrial structure upgrading in China, energy-saving transformation projects such as replacing the small with the large, energy saving and consumption reducing, and industrial environmental protection will continue to be carried out, which will generate a large number of demand for centrifugal fans.

The influence of high temperature on the air-conditioning fan is mainly the influence on the air-conditioning fan motor. Generally, the influence on the air blower and the inlet and outlet air buckle is not very big. But for the motor, we must pay attention to how to reduce the influence of high temperature on the air-conditioning fan, which is very important. 1. Influence of high temperature on the motor: under high temperature conditions, the cooling efficiency of the cooling system is reduced, the temperature in the engine hood is high, and the air density is reduced, which results in the decrease of the air filling coefficient and the power of the motor. Under the high temperature condition, because the motor is overheated, the process of thermal decomposition, oxidation and polymerization of lubricating oil is intensified. The higher the working temperature of the motor is, the faster the lubricating oil deteriorates. It not only increases the temperature of the oil pan, but also pollutes the lubricating oil, so that the viscosity of the lubricating oil decreases and the oil property becomes poor, resulting in the deterioration of the lubricating wear of the parts. In the skill protection, pay attention to the inspection of the oil level and shorten the oil change period properly. In dusty areas, the protection of air filter should be strengthened, and high quality engine oil should be selected when conditions permit. In addition to the above factors, the skill level of operators also has an important impact on product cost. With the popularity of air conditioning units, we can see the figure of air conditioning units. It not only provides us with a superior living environment, but also provides us with convenience. How can we effectively extend the service life of air conditioning unit? 1. Try to reduce the opening of windows, or add a layer of curtains and other shelters to reduce the heat and cold exchange between the indoor and the outside, which is more conducive to power saving; 2. Pay attention to the regulation of room temperature. No matter the refrigeration or heating can't adjust the temperature too far, 26 ℃ is just right and suitable for human body; 3. When installing the air conditioning unit, all connecting wires must be special and grounded; 4. The filter screen shall be cleaned regularly to prevent dust or other pollutants from blocking the filter screen and reducing the filtering effect so as to reduce the effect of cooling and heating; 5. Control the state setting of start-up and in use. When start-up, set the high wind to achieve the control purpose as soon as possible; when the temperature is appropriate, change the medium and low wind to reduce energy consumption and noise; 6. Adjust the leaves of the air outlet, the air conditioner sinks and the heating rises. Therefore, when cooling, the air outlet is upward, and when heating, the air outlet is downward, so the temperature regulation efficiency is greatly improved 7. The connecting pipe should not be too long. The outdoor unit should be placed in a place easy to dissipate heat. The indoor and outdoor connecting pipes should not exceed the recommended length as far as possible, which can enhance the cooling / heating effect. Qineng fan has an annual output of more than 50000 sets of various air-conditioning fans, with a complete range of products, including forward multi wing centrifugal, backward centrifugal, volute free centrifugal, axial-flow and other different structural forms, which are widely used in HVAC, new air-conditioning fan units, cold storage and other air supply and exhaust systems in various fields, such as buildings, buildings, rail transit, highway buses, etc.

What is the anti-corrosion design of forward leaning centrifugal fan? In addition, centrifugal fans will encounter corrosion problems after a period of use. The following is a detailed introduction of Zibo fan manufacturer: . After the machine type and main parameters are determined, according to the corrosion resistance of different materials in different environments, combined with its physical and chemical properties, cost performance and many other factors, the strength part materials are determined from the basic plane. From the material itself, the target material is safe. second, the mechanism design of the forward leaning centrifugal fan, an excellent design can extend the service life of the equipment and ensure the safety of the equipment. For the structural design, the design defects that are most likely to accelerate the corrosion are the stress concentration tendency and the crevice environment. Sometimes, although the corrosion rate is small in the metal immersion solution, the crevice is formed because of the chemical and electrochemical state of the internal solution The change will cause serious crevice corrosion. Third, the surface protection measures of centrifuge One of the basic ways to control corrosion is to isolate the corrosion environment. In the design of centrifugal fan, the methods of surface treatment, such as flange, galvanizing, chrome plating and chemical plating, are often used. These methods are effective in many environments, but for rotating parts, we must pay attention to an important phenomenon: the base material and plating are two kinds of materials, and their linear expansion coefficient is different, which will produce different deformation when the rotating parts are elastically deformed If the above phenomena exist, it will accelerate the formation of corrosion. .

In view of the fact that the efficiency, noise and sealing requirements of fans in chemical industry, steel industry and other industries have been continuously improved in recent years, the air conditioning fan manufacturers have timely changed their business ideas, accelerated the pace of product structure adjustment, and developed new energy-saving and environmental protection products by improving key components such as impeller profile, body structure and sealing form. 1. Before unpacking the fan, check whether the package is intact, whether the nameplate parameters of the fan meet the requirements, and whether all accompanying accessories are complete. 2. Carefully check whether the fan is deformed or damaged during transportation, whether the fasteners are loose or fall off, and whether the impeller is scratched. Check all parts of the fan. If any abnormal phenomenon is found, it shall be used after repair. 3. Use a 500V megohmmeter to measure the insulation resistance between the fan shell and the motor winding. The value should be greater than 0.5 megohm. Otherwise, the motor winding should be dried, and the temperature should not exceed 120 ℃. Chinese style 4. Prepare all kinds of materials, tools and site for fan installation. Chinese style In recent years, there are many fans in factories, mines, tunnels and other places. To ensure its effect, we need to strictly control the quality and develop new products.
