通過液體靜壓力壓頭差讀取真空計的方法This charged fiber can be directed or accelerated by electrical forces and then collected in mats or other useful geometrical forms. the diameters of electrospun fibers are in the range of tens of nanometers to several micrometers. in this paper, polyacrylonitrile ( pan ) nanofibers are made by electrospinning pan / dimethylformamide ( dmf ) and pan / dimethylacetamide ( dmac ) with adjusting the main process parameters including electrostatic voltage ( 20 ~ 50kv ), sprinkler aperture ( 0. 5 ~ 0. 8mm ), collection distance ( 15 ~ 25cm ), solution concentration ( 6 wt % - 14 wt % )
本文主要對聚丙烯腈（ pan ）二甲基甲酰胺（ dmf ） 、 pan二甲基已酰胺（ dmac ）體系進行電紡絲，調節靜電壓（ 20 50kv ） 、噴頭孔徑（ 0 . 5 0 . 8mm ） 、接收距離（ 15 25cm ） 、溶液濃度（ 6wt 14wt ）等過程參數，制得pan納米纖維，纖維平均直徑在200 1000nm ；詳細分析了過程參數對纖維細度、形態等的影響，認為高聚物溶液濃度及靜電壓對纖維細度有決定性影響，其它過程參數如接收距離、噴射孔徑、紡絲溶液溫度、溶液電導率等的調整應以這兩參數為基礎進行。Static pressure rating methods of square head fluid power cylinders
方頭液壓傳動缸的靜態壓力旋轉法Soundless pressing cnc makes the punch, driven by hydraulic pressure, shift during the work cycles to achieve the process of soundless press, that is to say, the punch die gets close to the material fast, and it penetrates the material till the material breaks, then the punch springs back quickly to reduce noises and vibration and assure the high production efficiency at the same time
靜音沖壓cnc控制液壓驅動的沖頭在工作循環中變速，實現靜音沖壓，即凸模快速接近材料，接著緩慢進入材料直到斷裂完成，然後沖頭快速返回，以減少噪音和震動，同時保證了較高的生產效率分享友人
