简化流理论为螺杆挤压 流动行为的粘稠液体在英吉利海峡的一个双螺杆挤出机螺杆中显示 类似的粘性液体的流动性能之间的平行板、无限 是静止不动的和其他运动。假设牛顿的行为 液体,一个微分方程推导双螺杆挤出机的速度的关系及 死的压力而死的几何和螺丝的操作变量。综合 给出了公式的特殊情况的粘度液体是不变的 在双螺杆挤出机螺杆通道(温热。给出了方程 在对案例的尺寸通道功能的螺钉位置 沿长度的螺丝。 在之前的报告(1)这个讨论会有关的文献的问题在挤出机是粘性流动的研究进展进行了综述。 在这篇文章中,但更多的发展。简化 有用的公式。这个命名的 摘要该文运用前款规定之论文(1)。 流动机制的粘稠液体在螺旋频道 螺杆可以更好地理解如果你可以想象的 通道被套装和设置在平坦的表面上。图1 显示这个概念螺杆的通道。如果这个底板, 代表螺旋曲面、固定不动,上部 板、筒表面,是代表的方向移动 相对运动的箭,将现有的相同 在桶中挤出机螺杆转动固定而。 假设液体潮湿,运动的 把桶的粘稠液体,而静止不动的 板具有大小相等、方向相反的阻力。速度的 液体,相对于螺丝,是最大的桶的表面 和零点的螺旋曲面。也有方向性的因素 参与,自英吉利海峡是倾斜的角度对方向,磷 运动。所以,在计算流量的通道 我们分手了速度分为两个组成部分:一个这样的行为 沿着通道,直接和其他成直角。 我们称这个组件的速度沿着通道阻力, 和组件的成直角这横向 速度。在最后的频道有一个死亡 或其他一些限制流量。这一压力梯度 沿着通道导致流动方向相反的 阻力。还有另一个 流,必须加以考虑。一般螺杆并不适合 完美的桶里。换句话说,有一个间隙 之间的顶部的螺纹和炮管的表面。

Extrusion machines made in production is the most widely used type of equipment, since the 19th century one since the advent fast development. Extrusion machine widely used in the work, so that in the sectors of the national economy has been widely used, and the hydraulic system and extrusion machine structure has more mature.The overall performance extrusion of hydraulic system depends on the machine, hydraulic system is the nature of the extruder, only decided by hydraulic system to produce larger extrusion pressure and do not break working stability, more perfect to achieve the design requirements. Design of high pressure, high flow rate should use the cartridge elements, the key components, so try to simplify imported hydraulic circuits, such ability can obtain reliable operation and maintenance performance.This design is mainly aimed at squeezing machine hydraulic systems of mechanism design main cylinder, main task is to design hydraulic principle diagram control hydraulic cylinder work. Main cylinder, is the core component of the extruder. System in the Lord by high-pressure liquid role in realizing fortress produce extrusion pressure columns work demands. Papers will detail main cylinder structure and other ancillary components design selection.This design based on the system design requirements, through repeated the plan adjustment of system is determined by calculating the main parameters, and choose seriously system components. This is designed using hydraulic system meet the job requirements and eventually with stable and reliable, the structure is simple characteristics.

双动机一般用来挤压无缝管,单动机挤压时是主缸前进,通过挤压饼把铝棒压向模具,从而成型。双动就是在主缸前进到达工进位置时,主缸内的穿心缸打出在铝棒中间打成空洞,穿心缸到达模具位置,模具是空的一个圆,穿心缸到达模具后,模具和穿心缸就会合成一个管型的模具,再通过主缸工进把铝棒从模具和穿心缸的缝里挤出,这样挤压出来的型材就可以达到无缝了。用单动机挤出的圆管是有缝的。用仪器才能验得出来。
