用途及特点：
　　2BEA系列水环真空泵及压缩机，是我公司在多年科研成果和生产经验的基础上，结合国际同类产品先进技术，研制开发的高效节能产品，通常用于抽吸不含固体颗粒，不溶于水，无腐蚀性的气体，以便在密闭容器中形成真空和压力。通过改变结构材料，亦可用刊由吸腐蚀气体或以腐蚀性液体作工作液。广泛用子造纸、化工、石化、轻工、制药、食品、冶金、建材、电器、洗煤、选矿、似巴等行业。
　　本系列泵采用单级单作用的结构形式，具有结构简单，维修方便，运行可靠，高效节能的优点，并能适应排水量大.载荷冲击波等恶劣工况。
　　我们对关键部件，如分配板，叶轮和泵轴进行了系统优化设计，简化了结构，提高了性能，实现节能。采用焊接片一次冲压、成形，型线合理;轮毅全部加土，从根本上解决了动平衡问题，叶轮与泵轴采用热装过盈配合，性能可靠，运行平稳。叶轮焊接后，整体进行良好的热处理，叶片具有良好的韧性，使叶片的抗冲击，抗折弯能力得以根本保证，能适应载荷冲击波动的恶劣工况。
　　2BEA系列泵，自带气水分离器，多位置没有排气口，泵盖设有排气阀检修窗口，叶轮与分配板间隙通过定位轴承两端压盖调整，安装使用方便，操作简单，便于维修。
　　我公司真空泵均经检测中心，严格检查测试，性能优越可靠耐用。
 

Shandong HUACHENG Group is a large-scale enterprise group combining R&D, production, and sales of vacuum pumps, slurry pumps, engine connecting rod reducers, and speed increasers as a whole. The group manages some companies, including Zibo Water-ring Vacuum Pump Factory Co., Ltd., Zibo HUACHENG Pump Industry Co., Ltd., Zibo BOSHAN HUACHENG Forging and Stamping Co., Ltd., and Shandong HUACHENG Sino-Germany Transmission Equipment Co., Ltd. (a Sino-Germany Joint-venture). The company is a key high-tech enterprise in China, management progress enterprise in Chinese engineering industry, Shandong high and new-tech enterprise, Shandong contract-observing and promise-keeping enterprise, and Shandong energy-saving and environmental-protection demonstration enterprise. The company is equipped with the unique Fluid Machinery Engineering and Technological Research Center and Provincial Enterprise Technology Center in Shandong. In addition, “HUACHENG” has been affirmed as China Famous Brand by the State Administration of Industry and Commerce.

　　Since 2003, output and sales volume of water-ring vacuum pump products manufactured by the company have been in the first place in the same industry in China for continuous nine years. Products are widely used in coal, papermaking, metallurgy, light industry, pharmacy, and chemical engineering. The company has presided over the drafting of five national industry standards, and independently researched and manufactured ultra-large water-ring vacuum pumps of eight specifications through scientific and technological innovation, to fill up international blanks, whose technical indicators are in international advanced level. 2BEC130 ultra-large water-ring vacuum pumps designed and manufactured by the company have been successfully applied in Sichuan Mianyang National Defense Wind Tunnel Icing Test and simulation test of Southwest Jiaotong University on high speed trains passing through tunnels. At present, the company is researching ultra-large vacuum facilities for carrying rockets in China, and such facilities are applied in Chinese unique projects.

　　The company aims at like products with internationally highest level, in accordance with promotion plan of equipment manufacturing industry and development direction of national new energy strategy. The company has invested RMB 1.68 billon Yuan in precision reducers and step-up gear boxes. The company has brought in the most advanced devices, including HOFLER CNC forming gear grinding machines (the first brand around the world), Germany Green Berg Gear Testing Center, AICHELIN multi-function thermal treatment production lines, Gleason spiral bevel gear grinding machine, Mitsubishi processing center, and Mori Seiki boring-mill processing center, to guarantee products’ requirements for precision, to develop and to manufacture various transmission devices and step-up gear boxes, and to occupy industry commanding height.

　　Such projects meet national industrial policies and leading products have achieved world-class level, participating in international competition representing the most advanced level in the same industry in China and filling domestic blanks. Project products are large in demand, wide in market, and leading in technology. After commission, it can produce 20,000 transmission devices and 2,000 step-up gear boxes every year, with RMB 6 billion Yuan of sales revenue, RMB 1.6 billion Yuan of profits and taxes, and 500mu of project planning area.

　　Project implementation has marched forward a solid step for promoting technological level of Chinese reduction boxes and laid sold foundation for promoting Chinese equipment manufacturing industry. During “the 12th Five-year Plan”, HUACHENG Group will make new and greater contributions to revitalizing national industry and promoting economic and regional development, with the objective that “build affluent HUACHENG, bring Billion Industry”.
