The mid- seventies , foreign industrial輸送system uses a ------ a kind of new air-cushion belt conveyor , the Jiegou its novel , innovative Yuan Li , significant energy savings , and a wide range of Shiyinggongneng , Attracted people’s attention . The early eighties , many European and American developed countries, in mines , ports , factories, extensive use of such a belt conveyor, made significant economic benefits, a great trend to replace belt conveyor idlers . Since 1986 , the company focused on technology , commitment to the application of air-cushion belt conveyor , achieved remarkable results. 1988 products by FX provincial technical appraisal in 1990 by the provincial new product development award by the State Planning Commission included in the " Eighth Five-Year "national key enterprise of new technology development projects. Now , the company has formed a cushion belt conveyor scale series production .

The second generation of new air-cushion belt conveyor innovation
1 , the innovative design theory ---- the advanced theory of water wave air flow replaced the fan with a larger air flow limitation theory , greatly improve the uniformity and stability of the air cushion .
2 , design innovation ---- second channel angular design to replace a channel angular design , the tank is more scientific and reasonable structure , to overcome the phenomenon of tape grazing , running effect increased by 20% , gas consumption savings of 15% .
3, the innovative layout orifice --- a five -point method to replace the orifice arranged in parallel arrangement method, not only optimize the matching air volume and pressure relationship , but also improve the carrying capacity of air cushion layer , and widened the air-cushion belt Conveyor applications.
4 , gas tank structure innovative modular gas box ---- to replace the whole gas tank , not only greatly reduce distortion, improving the sealing performance of gas tank , but also for maintenance and overhaul , once the damaged disc slot , do not Replacement of the entire solar terms box , you can just replace the disk slot , and greatly reduced maintenance costs.
5, air supply device innovation ---- additional points for the first time the wind streaming device, which not only reasonable sub- style diversion , but also greatly reduces the loss of air flow resistance , energy saving lead at home .
6, the wind source matching the first generation of air-cushion belt conveyor innovation ---- usually use 9 - 19,4 - 72 ,9 - 26 , 4 - 68 and other ordinary fans , these fans are not with air-cushion belt Conveyor to match the characteristics , leading to cushion poor stability . I fan with Xi’an Jiaotong University Research Institute successfully developed properties with air-cushion belt conveyor to match the new fans , not only scientific solution to the air volume and pressure of the matching relations , but also improve the uniformity and stability of air-cushion to raise the interest rate of 15 air % .
