The home-made application site of main drive seal of shield machine successfully held in Shanghai Hongrun

On May 6,2019 Beijing Jianke Huifeng Science and Technology Co. , Ltd. successfully held the technical exchange meeting of shield machine main drive sealing localization at Hongrun Construction Group (Fengjing Base), in association with Tunneling Machinery Branch of China Construction Machinery Industry Association and Hongrun Construction Group Co. , Ltd. .

Participants: Tunneling Machinery Branch of China Construction Machinery Industry Association，Hongrun Construction Group Co., Ltd，Beijing Jianke Huifeng Science and Technology Co. , Ltd.，China Railway Engineering Equipment Group Co., Ltd.（GREG），China Railway Construction Heavy Industry Corporation Ltd. (CRCHI) , Tianhe mechanical Equipment manufacturing Co. , Ltd.(CCCCTH), Shanghai Mechanized Construction Corporation Ltd.,(SMCC),Shanghai Tunnel Engineering Co., Ltd.,Shanghai tunnel shield company, Machinery manufacturing branch of Shanghai Tunnel Engineering Company,China Railway First Group Co., Ltd., (CRFG), China Railway Tunnel Group(CRTG), China Railway 19 Bureau Group Co., Ltd., Shanghai Shentong Metro Co., Ltd.,Huadi Constructing&Engineering Co.,Ltd..

At the meeting, secretary-general Song Zhenhua of China Construction Machinery Industry Association tunneling Machinery Branch made an important speech on the localization of the main drive seals of shield machines, and pointed out that the Ministry of Industry attaches great importance to the manufacture of major equipment and the localization of key components. China Construction Machinery Industry Association tunneling Machinery Branch will also actively promote this project. Therefore, the localization of shield machine parts is the general trend, and the main drive seal of shield machine, produced by Beijing Jianke Huifeng Technology Co. , Ltd. , used on the 10 # machine of hongrun Group Co. , Ltd.. proved the main drive seal developed and produced in China has met the requirements of imported seal products and field conditions. Therefore, technical exchange meeting of shield machine main drive sealing localization is necessary.

Chen Junqiang, chief engineer of Hongrun Construction Group Co. , Ltd. , made a detailed report on the use of the main drive seal of the shield machine at the meeting. Chen said that the four-lip main drive seal produced by Beijing Jianke Huifeng Science and Technology Co. , Ltd. for their shield machine in Kawasaki achieved good results. Compared with the imported seal directly, it can completely replace the imported products and realize the localization goal of the key components of the shield machine, which is a good news for the shield machine equipment manufacturers and shield machine construction enterprises! The invention solves the problem that the main drive seal of the shield machine has been dependent on imports, reduces the maintenance cost of the equipment, improves the efficiency, and provides more timely and efficient on-site service.
