New hydraulic balance valve theory research and product development
The main achievements of the unit: Changsha Jiaotong University, Shaoyang Hydraulic Co., Ltd., Hunan Pu Yuan Group Company Description Hydraulic engineering machinery in the road, railway, port terminals, mining construction and industrial and civil construction has won a very wide range of applications. Among them, the construction crane in the country's largest tonnage of about 50t, in order to reach 50t even more than 100t will be difficult, and its key components (especially the dual-luffing mechanism with hydraulic components) - hydraulic balance valve Is one of the biggest difficulties. The counterbalance valve currently produced in our country can not guarantee the performance requirements on large-tonnage cranes, especially the application of large-tonnage machine with two-cylinder luffing. The subject of the new hydraulic balance valve development, is fully investigated at home and abroad a variety of hydraulic balance valve performance characteristics, based on the proposed solution to these problems, and achieved success.
