2.Use of Liquid Crystal Material of High Polymer as the Rotary Vane of Direct Connected Vacuum Pump
3.Sliding vane rotary pump is a kind of product with producing in enormous quantity and widely being used in such industries as metallurgy, medicine, chemical, electron and so on.
4.Abstract: In this paper, the problems met in designing, producing and use of the rotary-vane vacuum pump are discussed. The solution methods and the research direction are given.
5.By means of adjusting the spiral angle and streaming area,different velocity fields,pressure fields and atomization angles are carried out to study the effect of the swirl distributor to the flow characteristics of the nozzle.
6.Conclusion The avulsion fractures of the ATFL can be clearly seen without superimposition at 15° external rotation with 45° of plantar flexion of foot,and the avulsion fracture of the CFL also can be clearly seen without superimposition at 45° internal rotation and tilt position of ankle.
7.Visit BOGNER OCEL, s.r.o. in Zebrak and lead yourselves by the product ranges like Trade, Blocks, Sheets in addition to Strips, Tool, High and rods.
8.Results The marker wire at insertion of the ATFL taken at 15° external rotation with 45°of plantar flexion appeared as an ellipse and the imitated avulsion fractures of the ATFL were clearly seen without superimpositipon at these angles,the marker wire at insertion of the CFL taken at 45° internal rotation and tilt position appeared as an ellipse and the imitated avulsion fracture of the CFL were clearly seen without superimposition at these angles.
9.In addition, it analyzes the supersonic aerodynamic characteristics of various arming vave mechanisms and the strength of their vaves. Finally , it gives calculation and experiment results on the basis of the arming vave mechanism for a bomb fuze.
10.Both the complicatedness varieties trees,the thick liquid material that the material differs greatly and the remaining leftover bits after wood processing,wood shaving,sawdust,sub thick liquid,cotton stalk,hemp stalk,bush,crudefiber crop,rice wheatgrass,reed,crudefiber crop,many kinds of goods thick liquid board,wasted paper,bagasse,agrimony etc.Canbe fasten separated into the good fibre with higher velocity and proper to rub a block of interval.
