The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. high quality Corbel tube The vibration of the unit is transmitted to the ground hall through the bridge connecting the sand blasting hose pipe, and the noise value reaches 45dB. In such an environment, people always feel uncomfortable. After the improved design, sandblasting rubber pipes were connected in series on the connecting pipes, which not only absorbed some of the noise generated by the unit vibration, but also the noise generated by the fluid pulsation in the pipeline system. At this time, the noise value in the ground hall was only 33dB, greatly improving the environment in the hall. The movable cylinder on the vulcanizing press will move upward and downward for the need of loading and unloading the mold. After repeated reciprocating movements, the copper serpentine will suffer from fatigue fracture. Although it can still be used after repair, it will cause time loss if it is stopped for repair. Corbel tube Price Although it has good soft properties and strong fatigue resistance, it is weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not continue after several months of use. The good comprehensive performance of sand blasting hose is fully reflected here. In the general industrial field, in addition to pressure and temperature, there are often severe conditions such as fatigue, corrosion, vibration, compression, impact, etc. Under such circumstances, it is most appropriate to use sandblasting hose to compensate for the position movement of the pipeline.

Ventilation pipes on ships are generally made of galvanized iron sheet high quality Corbel tube This kind of air duct is generally made by hand, and the production efficiency is low. Later, circular spiral air ducts made by machines greatly improved the production efficiency of air ducts and the quality of air ducts, which were widely used on civilian ships. However, for military ships with very strict height restrictions, circular air ducts obviously occupied more height than rectangular air ducts, which limited the promotion and use of circular spiral air ducts on ships. In the 1980s, 708 Research Institute, the Military Representative Office of Navy Garrison 426 Factory and Dalian Bohai Air Conditioning Auxiliary Factory jointly successfully trial produced the flat spiral air duct. It combines the advantages of the circular spiral air duct and the rectangular air duct. It is the third generation of air duct for ships, which is welcomed by the ship design department and has achieved good results after many ship use. The structure of the spiral air duct is the same as the round spiral air duct. It is also formed by rolling galvanized iron sheet on a special pipe coiler. Therefore, it can be produced mechanically, and the inner surface of the air duct is flat and smooth. The utilization rate of materials is also high. The thickness of galvanized iron sheet is generally 0.6mm. Although it is 0.75~slightly thinner than the commonly used rectangular air duct iron sheet, its rigidity is higher than that of rectangular air duct due to the reinforcement effect of spiral undercut. There are two types of flat spiral air duct: non adiabatic and pre adiabatic. Non adiabatic type is applicable to air conditioning ducts with simple mechanical ventilation, natural ventilation and external insulation. Taiyuan Corbel tube There are two types, one is air layer insulation, that is, there is 12.5~thick air layer between the inner pipe and the outer pipe. The other is that the inner and outer pipes are filled with thermal insulation materials rock wool or ultra-fine glass wool to become good thermal insulation air conditioning ducts.

Many people have never understood high quality Corbel tube 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, Corbel tube 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.

The development trend of HVAC duct is high quality Corbel tube Now more and more companies choose advanced spiral duct technology. The advantages of spiral air duct are as follows: 1. Good air tightness. Spiral air duct greatly reduces the connection of air duct and minimizes the leakage between connectors. The typical spiral air duct is 3-6m, but the typical rectangular air duct is only 1-1.5m; At the same time, only one connector is required to connect two spiral air ducts, while a typical rectangular air duct connector requires separate double flanges. 2. Standardized products. The production of spare parts (pipes and connectors) is highly automated and systematic, and has industrialized quality control. 3. Low installation cost. The installation of round duct only needs one third of that of rectangular duct. 4. Save space. Under the same pressure and the same installation space, the spiral air duct with a diameter of 200mm can replace the rectangular air duct with a diameter of 250x150mm. Without increasing the installation space, multiple spiral pipes can be used instead of wider rectangular pipes. Considering various factors, in most cases, spiral pipes require less space than rectangular pipes. Under the same pressure, the installation space of several spiral pipes is equal to or less than that of rectangular pipes. Most rectangular pipe systems require 4 bolts to fix, which will increase 40~80mm in each direction. 5. The pressure drop is low. As we know, spiral duct has lower ventilation resistance than rectangular duct. 6. Precision locking technology. Taiyuan Corbel tube The mold on the is made of special steel. After years of use, the surface remains unchanged, making the surface of the spiral air duct free of scratches and extending the service life. 7. The perimeter of rectangular air duct with length width ratio of 1:3 at the same section is 40% larger than that of spiral air duct, which means that spiral air duct saves more materials and reduces thermal insulation.
