Now on the market Kaifeng Air compression hose There are various models of galvanized air ducts. I believe you are familiar with galvanized air ducts. Do you know the main characteristics of galvanized air ducts? If you don't know, you can have a look. It will be helpful to purchase and use galvanized air ducts in the future. Galvanized air ducts refer to air supply, exhaust and smoke exhaust ducts used in hotels, shopping malls, textiles, chemical fiber, petrochemical, machinery manufacturing, instruments, electronics, medicine, tobacco, food, medical treatment, storage, office buildings, subway, civil air defense, basement and other projects. Its thickness and specification can vary according to requirements. Generally, when connecting, both ends of the galvanized spiral air duct are always externally connected to the accessories. Galvanized air duct metal air duct is made of various metal materials, commonly including galvanized iron sheet and stainless steel. With the continuous development of the tank industry at present, more and more industries and enterprises have applied to the tank industry, and more and more enterprises have entered the tank industry. Composite air ducts are composed of various inorganic materials, which can be divided into various types according to their composition, but most of them are lightweight, porous, and have large thermal resistance. First of all, the galvanized air duct is exquisite, compact, durable, beautiful, noble and elegant. The support and hanger of iron sheet air duct should be in the form and specification suitable for strength and rigidity according to the national standard atlas and specifications. The supports and hangers of extra wide, overweight and other special iron sheet air ducts with diameter or side length greater than 2500 mm shall be in accordance with the design regulations. Air compression hose Price High quality galvanized sheet is used. Condensate water pan is molded by molding process. There are no welding seams, welding spots, and thermal insulation materials (applied to industry and buildings) that meet the fire protection standards are connected to the water pan as a whole. The galvanized air duct is small in size, and the installation of drainage pipes and lines is simple and convenient. The left and right connecting pipes and return air modes can be changed at any time to match the site conditions. Galvanized air duct can be installed in any space.
Air compression hose Price It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Kaifeng Air compression hose It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.
The consumption of galvanized iron sheet air duct in China's chemical industry also shows a rapid growth trend. The rapid increase in consumption of galvanized iron sheet air duct in China's chemical industry has stimulated domestic Air compression hose Price With the rapid development of industry and the support of relevant government policies, in a short period of time, the production of galvanized iron air ducts in China has been developing rapidly. From the perspective of industrial chain, galvanized iron duct and upstream and downstream products enterprises of galvanized iron duct are interdependent and competing industries. Steel production enterprises can establish long-term and stable strategic alliances with downstream enterprises through deep processing of steel products, which is conducive to promoting the development of new varieties, quality improvement and market expansion of galvanized iron sheet air duct industry, and is an effective way to extend the value of steel products to the downstream and improve the competitiveness of the product market. It can be said that the development of high-quality galvanized iron duct projects has become a development strategy for Chinese galvanized iron duct manufacturers to cope with fierce market competition and improve product competitiveness. At present, in the consumption structure of galvanized iron duct in China, except for some high-end products that still rely on imports, middle and low-end products can basically achieve self-sufficiency. The situation that galvanized iron duct consumption completely depends on imports has been greatly improved, and the export volume is also expanding rapidly. However, compared with the developed areas of galvanized iron duct industry, China's galvanized iron duct industry system is not perfect, and there is still a big gap compared with Japan, South Korea and other large stainless steel reactor production countries. The development of galvanized iron sheet air duct industry in China started late, and the social demand for stainless steel reaction kettle grew too fast, which led to wear-resisting Air compression hose The first problem to be solved for industrial development is to rapidly increase output to meet the growing social demand, gradually replace imports, and complete the two steps of "quantitative change" and "qualitative change". At present, the development of galvanized iron duct industry in China has completed the accumulation process of "quantitative change", and is currently facing the transformation of "quality".
Kaifeng Air compression hose Prevention of vibration and noise during installation: the prevention of vibration and noise during installation is a key point in the installation process. The prevention of vibration and noise of spiral air duct during installation is mainly from the following aspects: 1. The fan and spiral air duct are connected by hose, and the hose at the suction inlet of the fan shall be installed with appropriate tightness, Avoid noise and vibration caused by reducing the area of air inlet and outlet due to loose soft connection. 2. The spiral air duct shall be made, installed and connected with the components. The connection shall be tight to reduce the gap and avoid air leakage noise. 3 In order to prevent the spiral air duct from vibration, fixed supports shall be installed at the turning of each system spiral air duct and at the connection with the ventilator and the air outlet for shock absorption. 4 The vibration damping device shall be set according to the design requirements or construction specifications during fan installation. Air leakage rate test of spiral air duct After the installation of spiral air duct, air leakage rate test is required. According to the specifications, the air leakage rate test of spiral air duct adopts the combination of light leakage legality and quantitative air leakage rate test. The light leakage method is suitable for the tightness test of medium and low pressure systems; The air leakage rate test is suitable for sampling inspection of medium pressure system and full detection of high pressure system. Light leak detection of spiral air duct Light leak detection is a qualitative method to detect the tightness of the spiral air duct of the system by using the strong penetration of light to holes. The test method is to use a bulb with protective cover whose voltage is not higher than 36V and power is more than 100W in the spiral air duct on a certain length of spiral air duct in dark environment, and slowly move from one end of the spiral air duct to the other end. If light can be observed outside the spiral air duct during the test, it indicates that there is a leak point in the spiral air duct, and repair the leak point of the spiral air duct. Air compression hose Price The light leak detection method of the low-pressure system adopts the method of subsection detection and summary analysis. The spiral air duct of the tested system is not allowed to have multiple obvious light leaks in the form of slits. The spiral air duct of the low-pressure system has no more than two light leak points every 10 meters, and the average joint of 100 meters is no more than 16; For every 10 joints of spiral air duct of medium pressure system, no more than 1 light leak point, and no more than 8 joints per 100 meters are qualified.
Many people have never understood wear-resisting Air compression hose It is better to use cast iron or rubber lining plate, so today I will give you a detailed analysis. The lining plate of the ball mill can tell you for sure that it is better to use rubber lining plate, which is also a trend for rubber lining plate to replace manganese steel lining plate. The rubber lining plate has many advantages that can not be achieved by manganese steel lining plates such as cast iron, so it has more advantages. One of the advantages of using cast iron or rubber liner for ball mill liner is that the noise of rubber liner is lower. In the process of grinding the rubber lining plate with materials, the noise is lower because it is not directly rubbed. Moreover, the rubber lining plate can throw the steel ball up for the second time to form the second grinding of materials, which makes the grinding of materials more thorough and the grinding fineness more uniform with good effect. In addition, the rubber lining plate can reduce the noise by an average of 30 dB compared with the noise of the cast iron lining plate, making it acceptable. Another important reason is energy saving. Energy consumption is an unavoidable problem for users of ball mills, because the cast iron lining plate is heavy in quality, Air compression hose Price Therefore, when the motor drives the lining plate, it will consume a lot of power. The rubber used by the rubber lining plate itself is light, so the electric energy consumed by the motor when driving is very small, which can be more than 10000 yuan of electric energy a year.
