Application of non-woven felt in groove press of high speed paper machines 无纺毛布在高速纸机沟纹压榨中的应用
Special angle strengthened bit design intensifying blade protection and quickly leading powder into screw groove, which reduce resistance and improve in-aperture speed. 特殊角度强化刀头设计,强化刃部保护,并将粉末快速导入螺旋沟槽,减少阻力,提高进孔速度。
The effects of rolling times, groove position and the roller speed on skidding was analyzed. 第一遍次辗压,沟槽位置越接近盘边缘,越容易打滑;
The groove depth was found to be inversely proportional to cutting speed and proportional to the number of passes. 沟槽深度与扫描速度成反比、与扫描次数成正比关系;
Groove high speed cutting technology and machining strategy 沟槽高速切削技术及其加工策略研究
Groove joints are sealed by sheet steel and wrapped with canvas. This new construction technology improves anti-seepage property as well as expedite construction speed. 对地下连续墙槽段节点采用钢板封口及外包帆布的施工新工艺,提高了构造的抗渗漏性能,也加快了施工速度。
Welding parameters such as angle of bending tip, pulse voltage, wire feed rate, pulse mode, size of groove and welding speed can affect the appearance of weld. 导电嘴弯曲角度、送丝速度、峰值电压、协同模式、焊接速度和坡口尺寸均会对窄间隙焊缝成形产生重要影响。
Along with the deepening of the spiral groove dry gas seal performance research, its application scope is expanded from the low speed and low pressure to the high pressure and high speed. 近年来,在干气密封的密封性能方面有了更深入的研究,使干气密封的应用范围得到了极大的提高,从运行的低转速和低压力扩大到高转速和高压力。
The spiral groove dry gas seal generates a finite amount of heat in high speed and pressure running, which will lead to the thermo-elastic deformation of the sealing ring. Consequently, the unstable operation and leakage increase will appear. 在介质压力和运转速度较高的工作状态下螺旋槽干气密封的密封端面间会产生较大的热量,从而使运行不稳定和泄漏量增大。
The conclusion is reached that the relative slip between the ball and groove is unavoidable, and with the increase of contact angle and lead angle, the revolution speed and spin speed is enlarged. 3. 理论研究发现,滚珠丝杠副中滚珠与螺旋滚道之间的相对滑动是不可避免的,随着接触角和螺旋升角的增大,滚珠公转速度和自转角速度都会增大。
Through the kinematics and dynamics analysis, its groove width and deep, forward speed, productivity, chain speed, cut soil thickness, cutting resistance and the total consume power and other basic parameters were confirmed. 2. 通过运动学和动力学分析,确定了其沟宽、沟深、前进速度、生产率、链速、切土厚度、切削阻力和总功耗等基本参数。
