The basic parts represented by fasteners are not only the basic industries of China's equipment manufacturing industry, but also the important foundations for various fields of national economic construction. During the twelfth five-year period, the number of construction machinery such as loaders, excavators, and road rollers will reach 6 million units, and the annual sales volume will be around 50,000 units. According to this estimate, the annual demand for high-strength fasteners is about 20,000 to 30,000. Ton.
In recent years, although the state has given certain support in the aspects of technology introduction, technological transformation, and scientific research and development, there is still a small gap compared with the current market demand and foreign standards. The specific manifestations are: low product varieties and low levels. , The quality is unstable, early failure rate is high, and reliability is poor.
During the period of the 12th Five-Year Plan period, the industry must rely on new advantages such as technological progress, quality improvement, and product cost-effectiveness to achieve sustainable development while maintaining its partial cost advantage. It is estimated that by the end of 2015, the total output of the industry will reach 7.5 million to 8 million tons; under the overall situation of expanding exports, the export products will assume a fluctuating growth trend, and the average annual export growth rate is expected to be 8% to 10% during the 12th five-year period. By 2015, the total export volume of the industry will reach 30 billion yuan.
At present, domestic fastener factories are limited to funds or other reasons, and more domestic and Taiwanese equipment are used to produce automotive fasteners. To ensure large-scale production of high-end fastener products, the dimensional tolerances and form-position tolerances should be increased. Online monitoring tools and mold making levels. Eliminating non-conforming products in production to ensure the assembly quality of OEMs and OEMs.
Under the huge market demand, how to ensure the orderly development of China's fastener industry will be the main problem facing it. The formulation of relevant strict industry standards in China and the improvement of industry chain access thresholds will be a strong support point for the orderly development of the industry.
Mine Touch Sprinkling Dust Reduction Device
We know the fog prevents dust particles from becoming airborne due to creation of envelop around the sources of dust generation. With the help air driven device known as nozzle fog is generated and is passed through high frequency waves of sound. Generation of primary shock waves takes place with acceleration of air stream above sonic velocity by the acceleration of internal coverage nozzle section. Primary shock waves get amplified with the resonator of nozzle by the reflection of air stream through the resonating chamber in the path of air stream. The water delivered through annular orifices that pass through primary zone of wave`s sherd into the small droplets. These droplets again get in to small sizes by the passing through the zone of shock waves with the help of primary air streamer. Lastly the resonating chamber helps to flee the air and carries droplets downstream in low velocity and soft fog patterns.
