In recent years, with the leap-forward development of coal, metallurgy, and chemical industries in China, the technical requirements for related supporting equipment have become higher and higher. Recently, a private enterprise in Zibo has successfully developed a world-scale super-sized water ring vacuum pump, and its technical level has reached the international advanced level.
In the 20,000-square-meter workshop of Zibo Water Ring Vacuum Pump Factory Co., Ltd., the reporter saw this “giant thing”. The staff introduced that the machine weighs 100 tons. Its working principle is to use the air volume in the machine to achieve suction The purpose of Qi. Chen Weimao, chairman of Shandong Huacheng Group, where the company is located, introduced that the project has been developed for nearly 2 years and invested nearly 20 million yuan in research and development.
He said that at present, the world's largest vacuum pump can pump 560 cubic meters per minute, but the company's "2BEC100" vacuum pump can pump 1000 cubic meters per minute. Not only that, but compared to before, when the machine is working, it can save 20%.
According to the “Science and Technology Achievement Appraisal Certificate” issued by the Shandong Provincial Department of Science and Technology, the reporter saw its appraisal report read: “This product has a significant energy saving effect, and the gas isothermal compression efficiency reaches 60%. The new scientific investigation report issued by the new consulting unit proves that the domestic and foreign documents have not reported the large suction volume and high efficiency water ring vacuum pump of the product. The main performance indicators of the product have reached the international advanced level and it is an international initiative. ”
The reporter learned that gas explosion accidents in the coal industry have occurred frequently in recent years, which seriously threatens the lives of miners and the country’s property safety. Therefore, the state attaches great importance to the suction and discharge of coal gas. Chen Weimao said that after the successful development of the project, it immediately put into mass production. At present, it has received 22 orders from domestic and foreign companies, 8 of which are sold to Zambia in Africa.
