Chen Hua Machinery Co., Ltd. Qingdao liquid metal forming processes and more ports bollard products, and it is difficult to precisely control, making the casting quality is not stable enough. Compared with the forging of the same material, because the liquid forming tissue loose, coarse grains, internal easy to produce shrinkage, shrinkage, porosity and other defects. Its low mechanical properties. Another steel bollard, labor-intensive, poor conditions. Have excellent mechanical and physical properties, it can have a variety of strength, hardness, toughness overall performance, but also combines one or more specific properties such as wear resistance, high temperature and low temperature resistance, corrosion resistance and so on. Chen Hua machinery (Figure), port equipment bollard, bollard harbor provided by the China Machinery Equipment Co., Ltd. Qingdao Chen. Chen Hua Machinery Co., Ltd. Qingdao, strong, credible, in Qingdao, Shandong CNC machine tool industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Chen Hua machinery and you hand into the brilliant, for a better future! ]: Peaking power plants and power stations downstream water flood cause short ups and downs, a direct impact on the downstream vertical pier berthing and loading and unloading safety. Reference Lock floating bollard principle study presents a new floating dock mooring bollard system is suitable for the instantaneous amplitude level, gives ideas and methods to solve problems downstream berthing plant. To further verify the operational reliability of floating device, namely a greater role in river flow horizontal force case, buoys how to overcome resistance (anti-jamming) free lift 1500kn bollard, respectively, under a single unit and multi-unit properties circumstances force conducted further analysis, proposed a set of increased anti-card guide wheels and anti-card linkage method, which can effectively prevent the pontoon Run "stuck." In this study, the use of the device in the actual project to lay a solid foundation, and provide reference for similar engineering design. 150kn bollard bollard _ _ Chen Hua machinery provided by China Machinery Co., Ltd.
