With a double-thread screw ,the nut motion is two pitches ,and, in general,the motion of the nut per screw rotation will be the lead(the pitch times the number of threads).

对于双头螺柱，螺母移动两倍的螺距，通常螺栓旋转一圈，螺母移动的距离为导程。

The 3D Newtonian isothermal flow of normal double-thread screw element, normal triple screw element and VCR element was simulated.

第二部分则是在熔体输送段引入VCR元件，通过对常规双头螺纹元件、三头元件和VCR元件流道进行三维等温流场的模拟与分析。

The numerical analyses also showed that VCR element has the best distribute mixing effect and normal double-thread screw element take the second place, normal double-thread screw element is the weakest among them.

模拟结果表明：常规双头螺纹元件分散混合能力最强，常规三头螺纹元件次之，VCR元件最弱；而VCR元件分布混合能力最强，常规三头螺纹元件次之，常规双头螺纹元件最弱。

Cut off the power supply of the accumulator before installation, remove the former top light, pull out the original electric line with care while confirming the function of each hole of the base board, fix the base board with screw (better use the original top light screw), connect the down-lead of the product and bind to up, stuff the leftover back into the top shed, in sert firmly the main body, set the glider and fix it.

安装前必须先断开蓄电池的电源，然后拆下原车顶灯，小心拉出原电线，同时确认每条线的功能，参考上图，将原车软线穿过基座板中心孔，并用螺丝将本品引线相应接上并包扎好，然后将多余的引线塞回顶棚，同时再将主体牢牢地嵌入，滑动镶好进行固定。

We commend you for the main products: There are all kinds of plastic tubing, profiles, sheet, plate full production lines, single / double-screw extruder, crusher series, the feeder series, the series of dry, high-speed mixer series TSK series and parallel with twin-screw extruder granulator.

我们为你推荐的主要产品：有各种塑料管材、型材、片材、板材全套生产线、单/双螺杆挤出机、破碎机系列、上料机系列、干燥系列、高速混合机系列以及TSK系列同向平行双螺杆挤出造粒机。

They range from large industrial extruders with screw diameters up to 6 or 8 in .down to the laboratory model with a 3/4in diameter screw .

他们范围从大工业挤压机以螺丝直径由6 或8 决定在down 对实验室模型与3/4.in 直径螺丝。

The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.

在压力升高的同时，塑料一方面被外部加热，另一方面塑料本身在压缩、剪切、搅拌的运动过程中，由于内磨擦力也产生了大量的热，在外力和内力的联合作用下，塑料温度逐渐增高，其物理状态也经历了玻璃态--高弹态--粘流态的变化，一般地说来，在加料段中主要是玻璃态，在螺杆螺纹逐渐减少的中间部分压缩段中，物料主要处于高弹状态，同时也逐渐的熔融，而物料到压缩段后部和化段作用处于粘流态了，这时我们称塑料已完全塑化了，由螺杆推力作用将塑化的塑料定压定量的从机头中挤出。
