Fourth, to avoid breaking material: Screw must not be allowed in the case of blanking operation, upon occurrence of the stator as dry friction of rubber, produces instant heat and burn, so good grinder, screw grille flow is a necessary condition for normal operation To this end, some screw pump body is also expected to stop off device installed, when there Fracture, because he has a self-priming screw pump function of the characteristics Chemical pumps of the body will produce a vacuum chamber, vacuum screw pump will stop operation.

四、避免断料：螺杆泵决不允许在断料的情形下运转，一经消防泵发生，橡胶定子由于干摩擦，瞬间产生高温而烧坏，所以，粉碎机完好，格栅畅通是螺杆泵正常运转的必要条件之一，为此，有些螺杆泵还在泵身上安装了断料停机装置，当发生断料时，由于螺杆泵其有自吸功能的特性，腔体内会产生真空，真空装置会使螺杆泵停止运转。

Screw must not be allowed to break at the expected operating circumstances, once happened, rubber stator do because of friction heat generated instantly burned, so, good grinder, screw grille flow are a necessary condition for the normal operation of one of For this reason, some screw pump was also installed devices break down material, when the expected happened when broken, because of the screw pump has self-priming function of its characteristics, the body will produce a vacuum chamber, vacuum devices will stop screw operation.

Screw does not allow for the case of run-off materials, once occurred, rubber stator due to dry friction, the heat generated instantly burned, so grinder intact, grille flow is a necessary condition for the normal operation of pumps, one of To this end, some screw pump is also installed in the body break down plant material, as occurs when the material off, because he has a self-priming pumps feature the characteristics of the body will produce a vacuum chamber, vacuum devices will screw pump to stop operation.

A software for aided designing bolt of tunnel named ANSYSBOLT was designed on the basis of ANSYS finite element software. In the software environment, bolt supporting model of physical tunnel in tectonic stress field was structured according to physical parameters of coal and rock seam of some working face, and in conditions of different buried depth, bolt supporting structure and pre-tightening force, distributions of stress of surrounding rock of physical tunnel and its displacement were analyzed and calculated by ANSYSBOLT software. Then influence of different buried depth, bolt supporting structure and pre-tightening force on stability of roof and floor of tunnel was analyzed and finally feasible scheme of bolt supporting was gotten according to the analysis result.

在ANSYS大型有限元软件基础上开发了巷道锚杆辅助设计软件ANSYSBOLT；在该软件环境下，根据某工作面煤岩层的物理参数，建立了构造应力场条件下的实体巷道锚杆支护模型，并按照不同的埋藏深度、锚杆支护结构和预紧力条件，经软件分析计算，得出了实体巷道围岩应力及位移分布情况，进而分析了不同埋藏深度、锚杆支护和预紧力条件对巷道顶底板稳定性的影响，最终根据分析结果得出了可行的锚杆支护方案。

Screw pump the working principle is: screw pump work, the liquid after being inhaled into the screw pump shell and sealed by Wai space, when the initiative screw rotation, the screw pump seal volume in the squeezed increase Luoya Screw pump pressure, and along the axial movement.

螺杆泵的工作原理是：螺杆泵工作时，液体被吸入后就进入螺纹与泵壳所围的密封空间，当主动螺杆旋转时，螺杆泵密封容积在螺牙的挤压下提高螺杆泵压力，并沿轴向移动。

Polymer processing is a high-energy process operation, and screw machinery is widespread applied to the polymer processing, such as screw extruders, screw injection molding machine and so on. The screw plasticating and conveying equipments based on shear rheology are generally adopted in polymer processing, in which materiels are dominated by shear stress. Therefore, there are some ubiquity disadvantages of the current methods of polymer materials processing, such as long thermo-mechanical, high energy consumption, too big equipment structure, and dependence on material properties.

加热管高分子材料成型加工是高能耗过程作业，目前普遍采用螺杆机械，如螺杆挤出机、螺杆注射机等，在螺杆机械中物料塑化输运主要是靠螺杆旋转时对物料的拖曳作用，固体输送为摩擦拖曳，熔体输送为粘性拖曳，物料的速度梯度与其流动和变形方向垂直，这种流动与变形受剪切应力支配，所以当前的高分子材料加工方法普遍存在物料塑化输运所经历的热机械历程长、能耗高、设备结构大、对物料特性依赖性强等缺陷。

After abrasion of anti strapped bar pallet, drain plate, mud and sand are piled in Kelly bar and cause packing strapped bar, after drilling in thick mud sand, mud and sand have to be cleaned before storing Kelly bar (it is prohibited to drill in under this condition, but in fact, it always happened).

防带杆托盘、流水盘磨损后，泥砂积存在钻杆中引起塞物带杆，在稠泥砂中钻孔后，钻杆存放前要清除钻杆内的泥砂（这种情况下钻孔是不允许的，但实际钻孔中经常发生）。

The carbon fiber coiled rod proceed compare,analyses different kinds of carbon fiber coiled rod 'mer with carbon fiber world face bonding instance,and different kinds of carbon fiber coiled rod' mechanical property,thereby erect differ mer 'sucker rod not so much mechanical property of compartment' parallelism relation,thereby gist these one relation design new style dispensation 'carbon fiber reinforced polymer composite coiled rod for as well of the these theses versus available different kinds of differ mer.

本论文对已有的各种不同基体的碳纤维连续抽油杆进行比较，分析各种碳纤维连续抽油杆的基体与碳纤维的界面结合情况，以及各种碳纤维连续抽油杆的力学性能，从而建立不同基体的抽油杆与其力学性能之间的对应关系，从而依据这一关系设计新型配方的碳纤维增强复合材料连续抽油杆。

Resorting to the Roberts-Chebyshev theorem,we replace the two cranks of a crank-rocker cognate mechanism with a double bar,which is required to satisfy certain geometrical and motion conditions,and we change the mechanism thus reformed into a geared five-bar mechanism so that one of its links can fully rotate with the link connected with it.

借助于Roberts-Chebyshev定理，将曲柄摇杆轨迹同源机构的两曲柄分别用一双杆组代替，并要求双杆组满足一定的几何尺寸条件和运动条件，使变形后的机构为齿轮五杆机构，且满足机构的一个连架杆以及与其相连的连杆能够整周转动。
