A cold blow Sweeper years of strong military research and technical strength and civilian jet fan on the successful experience of the Gas Turbine Research Institute of China Aviation Industry Corporation , 5707 factory jointly developed with independent intellectual property rights of non-aviation products . The product has reliable performance, high efficiency, low fuel consumption , high level of automation , environmental protection and economic advantages . Successful debut on the 8th China Chongqing Hi-Tech Fair , to lay a solid foundation to develop new markets, foster new economic growth point . Purge car is snow on the high-speed spray nozzle exit of the exhaust pipe temperature gas purge road dust dedicated purge equipment , mainly used in airports, highways clean, purge the gravel on the runway , snow and dust cleaning operation. Purge vehicle lengthened trucks , diesel engines, high-elastic coupling , gear boxes , couplings , type II fan , exhaust purge piping and monitoring devices and other components , the components are fixed on a special bracket . Firstly blowing snow blower principle prototype ( type I blowing snow blower ) trial based on , in order to effectively reduce the manufacturing cost of the fan to improve the cost , in general, do not change the general structure and performance indicators premise under Prototype , carried out on the fan optimized design, the development of a single-stage supercharger axial fan ( type II jet fan ) , type II design flow patterns around the three-dimensional simulation software , and then meet the design requirements for aerodynamic performance assessment test . Then fan purge indicators of actual performance and requirements , select the appropriate equipment , and three-way purge purge car exhaust pipe design work performance estimation flow field check on the performance of the related equipment separate commissioning, equipment and piping be installed of control of purge cars , power nozzle joint commissioning , final implementation approval test to verify that the purge cars , purging device ( fan ) the overall performance and reliability . This article focuses on type II the fan performance assessment and purge piping checking design work , the assessment results with the design specifications of the fan performance in good agreement , the purge trials show that the pipeline designed to meet the design requirements . Therefore, development of new purge car is successful.
