Auto - loading measuring control system for liquid production in train loading crane system 定量自动装车技术在液态类物料鹤管装车系统中的应用
Its mechanism is expatiated and its work principle is explained with the crane system 通过对系统原理及平衡阀的结构分析,开发设计了带旁通油路的平衡阀。
Noell crane systems ( china ) ltd . , located in china merchants zhangzhou development zone , is its base in asia - pacific area 诺尔中国是其在亚太地区的制造基地,坐落于招商局漳州开发区,与厦门隔海相望。
Noell crane systems is one of the advanced manufactory of the port machinery in the world , with more than two hundred years of experience in this field 诺尔起重设备公司是世界港口机械制造行业的领先企业之一,在该领域有两百多年的历史。
Besides the usual crane systems , continuous use under water in the loading machine is the particular technical challenge that the measuring apparatus has to meet 除常用起重系统以外,在装载机中不间断水下测量对于测量仪器来说是个特殊的技术挑战。
A new method is necessary . in this paper , we employed the i - deas software to developed a 3 - d model and make a finite element analysis ( fea ) on slewing frames based on the nominal loads and geometry parameter of crane qtz63 , aimed to find the principle of the area with high stress and big deformation and estimated the effect on the whole tower crane system 本文以qtz63塔机为研究对象,按设计提供的载荷及几何参数,运用i - deas软件先对回转支承系统三维建模,再进行结构有限元分析,依据强度及变形结果,找出塔机各种工况下高应力区域、变形明显部位出现的规律,并分析对塔机系统产生的影响。
