Comprehensive evaluation of world conveyor belt production Suction pipe The development level and the application practice of large industrial and mining enterprises in China, in the future, the technology and market development of conveyor belt vulcanizers in China will show the following eight characteristics: more intelligent: Canada Xiaoai Group has recently launched a new X-PAD conveyor belt vulcanizer control system, which uses full touch color screen control, and one operating system can implement real-time monitoring on multiple pairs of vulcanizer heating plates, And it can conduct remote monitoring through WIFI. This system will greatly improve the intelligent control degree of conveyor belt vulcanizer, and undoubtedly represents an important trend in the future development of conveyor belt vulcanizer technology. Higher cost performance: With the improvement of refined management of industrial and mining enterprises, the extensive "stupid and bulky" equipment can no longer adapt to modern production, and the provision of "customized combination" system solutions will become an inevitable choice for future conveyor belt vulcanizer suppliers - conveyor belt vulcanizer is a "tool type" equipment, Suppliers or design units can assist industrial and mining enterprises to comprehensively analyze the belt width, lap length and other use conditions of the conveyor system, and customize the overall solution of the conveyor belt vulcanizer that can be applied to multiple belt joints and maintenance at the same time. So as to effectively reduce procurement costs. More security: in terms of security measures, Suction pipe Where can I find it? As the leader in the conveyor belt vulcanizing machine industry, Xiao Ai segmented vulcanizing machine can be used as a model: (1) its beam system adopts aviation grade aluminum profile, zhuanliE design, and has a safety window. When it is used, it penetrates the safety bar, and is equipped with a safety pin protection system; (2) International certified cables such as American UL are used to fully ensure the safety and reliability of use. (3) The recently launched new UBR vulcanizing machine pioneered the use of new materials to replace the bolt structure with a strong rope system, and designed a related structure between the new beams, which used the safety protection measures of the vulcanizing machine pressurization system to the extreme.

production Suction pipe The manufacturing of is highly automated and the production speed is very fast. The general air duct can produce 20~40 meters per minute. Due to the low price of its raw material galvanized strip steel compared with the whole galvanized steel sheet, and its factory production and specification standardization, the cost of spiral air duct is lower than that of rectangular air duct; In addition, the total cost of spiral air duct is low due to the less demand for supports and hangers and the less installation work. Since the four corners of rectangular air ducts are prone to turbulence, reducing the effective flow area, the spiral air ducts have good air fluidity and large effective flow area, so the secondary noise of spiral air ducts is low. Because the spiral air ducts are strong, the low-frequency noise caused by air duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation system consumes less power. Spiral air ducts in the market are generally divided into three categories according to their materials: galvanized spiral air ducts, stainless steel spiral air ducts and composite spiral air ducts. Among them, spiral air duct has the best quality and strong applicability, but its price is high. At present, the most widely circulated spiral air duct on the market is galvanized sheet. The galvanized sheet spiral air duct is basically the characteristic of stainless steel spiral air duct, but its price is only two thirds or even lower than that of spiral air duct. Heze Suction pipe It is generally used in places where the external environment is relatively common and the requirements for air ducts are not too high. As the iron sheet is prone to chemical reaction in various environments, corrosion and rust will occur. However, zinc hardly changes in dry air. In humid air, dense basic zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with zinc on the iron sheet of the air duct to protect the iron sheet. The protective and decorative properties of zinc coating can be significantly improved after passivation treatment, dyeing or coating with light protecting agent.

Heze Suction pipe 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. Suction pipe Where can I find it? 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.

production Suction pipe The inner and outer walls are smooth, the resistance of the air duct is small, the secondary noise is not generated during air supply and exhaust, the energy consumption is reduced, and the operation cost is saved. The product can be made on site, cut, drilled, and opened, the installation is simple, and the labor and time are saved. The user's investment cost is reduced, the construction period is shortened, the performance price ratio is high, and it is cheaper than other materials. After the installation is completed, no maintenance is required, and the maintenance cost is reduced. The key points of whether galvanized sheet air duct material galvanized sheet is corroded are mainly reflected in the following three aspects: ① The first corrosion of galvanized sheet in the entire service life cycle is the oxidation of the galvanized layer on the surface, resulting in white rust. After a little longer time, the white rust on the surface further reacts with carbon dioxide and other impurities in the humid air to form black spots. When the galvanized sheet is used for a long time and the galvanized layer is severely corroded, the steel base loses the sacrificial anti-corrosion effect of zinc, and begins to oxidize to generate red rust. Once the steel base begins to oxidize, the corrosion rate becomes very fast, and the life of galvanized sheet ends. ② In addition, there are two special corrosion conditions of galvanized sheet, namely, black stain. One is that after being used for a period of time, due to the influence of lead and other elements in the zinc coating, the galvanized sheet will become black in the matte part of the zinc flake. The blackened zinc coating still has a protective effect on the steel base, but has a certain impact on the service life. ③ Suction pipe Where can I find it? It has excellent corrosion resistance in dry or pollution-free environment. However, in the polluted environment, the service life will be greatly shortened, so it is necessary to pre coat the film into color plates before use.

“ production Suction pipe What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, Suction pipe Where can I find it? It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.
