| Wuhan Xin Wenfeng Machinery Co., Ltd is a new co***ny to major manufacture the mine machinery equipment. It has an advanced research center and a R&D team with rich experience with an effort to the development and test of rock drill and tools. In recent years, the co***ny has succeeded in developing the patent product, YDT31 New Type Powerful Electric Rock Drill, which has passed the Science & Technology Achievements Expertise Organized by the Ministry of Metallurgy Industry , and regarded as ˇ°having achieved the intemational advanced level in the field and made a new contribution to the development of electric rock drill in our country ˇ±. For drilling in dense granite (f=14~16,¦Ňb=140~160***), the penetration rate is up to 180-280mm/min (bit diameter 36mm), which is 30% faster than that of the similar products , 70% faster the ordinary small pneumatic rock drills. The energy utilization efficiency is up to 53.1%,which is 7 times as that of the small pneumatic rock drill(7.7%). By calculation of operating time as 300 daysˇÁ5 hours for a year per drill set, it can save electricity by 11820 kilowatt-hours. Furthermore, by calculation for 1000duill sets, this can save electricity up to 11.82 million kilowatt-hours per year. The resulting profit on electricity economization is 7.683 million yuan RMB per year. It needs neither air compressing facilities nor pipelines, and can operate normally even in site without electricity by means of diesel engine Therefore, lots of basic construction capital can be saved, and the safety of workers, field as well as equipment can be ensured. A series of products are developed on the basis of the YDT31 electric rock drill, such as hand-beld, flexible, electric-hydraulic rock drills as well as drill wagon. These are extensively used in high-way, railway, airport runway, geological survey, metallic and non-metallic mines,national defense and other kinds of engineering field. |
