我国中小直径焊管经过20世纪80~90年代的飞速发展，品种结构和应用领域已经有较大的改善，但是低压流体输送管、一般结构管比例较大，与焊管发达国家在锅炉、化工、油井、机械构件、高压流体输送用承压钢管和精密钢管领域不断扩大焊管的使用范围、提高高等级焊管使用数量方面存在一定的差距。

The cap device includes a cap body having an inside transfer path for connecting an inlet opening for introducing the fuel and an outside transfer pipe, a fixed outer cap including a connector for fixing a discharge opening into which the transfer pipe is inserted, and an elastic opening/closing section in which the cap body is elastically compressible by the connector, and wherein the inside transfer path opens during the compression.

盖帽体具有用于将引导燃料的入口和外部输送管连接的内部输送通路。被固定的外盖帽包括使内部插有被固定的外盖帽的排放口固定的连接器，盖帽体通过连接器可弹性地被挤压在弹性开启/关闭部分中，挤压时内部输送通路开启。采用本发明的燃料箱即使燃料箱急剧摇摆或倾斜于其侧面也可以连续而平稳地提供燃料。

Firstly, the natural frequencies and normal mode shapes of the fluid-conveying pipe with zero fluid velocity (i.e. U=0) were determined with the transfer matrix method. Next, these natural frequencies and normal mode shapes were used to derive the equation of motion for the fluid-conveying pipe with fluid velocity U.neq.0 by using the expansion theorem. Finally, the free and forced vibration responses of the pipe with flowing fluid were obtained by means of the Jacobi method and the Newmark direct integration method.

首先吾人使用转移矩阵法来求取一流速等於零(即U=0)、跨距数为N之流体输送管的自然频率及其所对应之正规化振态，然后利用振态重叠法原理来推导流速不等於零(即U.neq.0)时，整个流体输送管在外力作用下的运动方程式，最后再以Jacobi法及Newmark直接积分法来计算该水平流体输送管的自然频率及强迫振动反应。

MQ-LSC screw conveyer is mainly composed of the following parts: steel screw, driving device, feed hopper, conveyance trough or conveyance pipe, material outlet, frame, etc.
