By the Xi'an Valve Factory Co., developed "XGB150-100-400 zirconium acetic acid mother liquor circulation pump, 8" X343F-150LbZr type zirconium and zirconium alloy plug valve "in August 21st in Xi'an by experts of China Petroleum and chemical industry federation.
Zhang Yubao Secretary of the China General Machinery Industry Association, Li Yukun branch of the Secretary-General, Forged Steel Valves branch secretary-general Song Yinli attended the meeting. The two products are used in acetic acid industry strong corrosive medium, after mainly depends on import.
Xi'an Valve Factory Co. Ltd. through vacuum melting and centrifugal casting process, and the technology to optimize the casting structure and casting system simulation using CAE, successfully solves the problem of zirconium pump, Cast Iron Valves parts, casting, to ensure the quality of castings. Among them, the empirical coefficient range of hydraulic design of zirconium single-stage centrifugal pump to dare to break the normal procedure, the successful practice of new ideas in design of centrifugal pump speed, high lift, high speed lower than.
In addition, to ensure that the valve seal zirconium, the cock shaft cone own self sealing technology; plug end flange type anti cold flow structure design; plug valve seal card sets of multilevel inlaid with new technology; and the O type sealing ring for sealing parts cock, established four sealing system. Products by the Henan Shunda Chemical Technology Co., Ltd., Shandong Hualu-Hengsheng group, Kingboard (Hebei) Chemical Co., Ltd., Shanghai Wujing Chemical Co., Ltd. and other users for more than a year, to prove that the product is reliable in operation, stable performance, welcomed by the users.
Experts agree that, by the Xi'an Valve Factory Co., developed "XGB150-100-400 zirconium acetic acid mother liquor circulation pump, 8" X343F-150LbZr type zirconium and zirconium alloy plug valve "is a domestic initiative, fully meet the requirements of acetic acid production in china. The main technical performance parameters and indicators have reached the international advanced level, can replace imported, can be mass production.
