螺体

This is a hollow steel cylinder, usually about 2 to 3 inches in diameter, that can be moved several inches longitudinally in and out of the upper casting by means of a hand wheel and screw.

通过手轮和螺杆，尾座套筒可以在尾座体中纵向移入和移出几英寸。

At the same time, has advanced with the twin-screw extruder, high-speed mixer, such as production equipment, has injection molding machines, infrared spectrometer, electronic universal tensile tester, melt flow rate meter, Shore hardness tester, anti-aging testing machine , weathering testing machine, such as laboratory equipment.

同时拥有先进的同向双螺杆挤出机、高速混合机等生产设备，有注塑机、红外光谱仪、电子万能拉力试验机、熔体流动速率测定仪、邵氏硬度计、耐老化试验机、耐候试验机等实验设备。

This type of tubing anchor is constitute by anchor body,turnover slip and the centralizer,it is installed in the lower end of the PCP.When the rotor is rotating,it drives the shell and rotary anchor to rotate clockwise.In the role of the friction between turnover slip and the casing,the turnover slip turns over , its outer diameter increases,then it locks to the casing and the anchoring implements.

这种油管锚由锚体，翻板卡瓦和扶正体等组成，安装在螺杆泵下端，泵转子旋转时，带动泵外壳，旋转锚顺时针方向转动，在翻板卡瓦和套管摩擦力作用下，翻板卡瓦向外涨出，外径增大，卡封在套管上，实现锚定。

With the continuous drive of the screw, the liquid will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally.

随着螺杆的连续传动，液体以螺旋形方式从一个密封腔压向另一个密封腔，最后挤出泵体。

Product performance has been progressively with the international market, such as rubber and synthetic fiber in twin screw extruder machinery and equipment on the application of high-temperature melt pressure sensor and ancillary industrial instruments, fully replace the United States and Italy Dynisco Barmag GEFRAN and Germany and other products This can also provide imported pieces.

产品性能已逐步同国际市场接轨，如在橡塑化纤双螺杆挤出机械设备上应用的高温熔体压力传感器和配套工控仪表，完全可替换美国Dynisco及意大利GEFRAN和德国巴马格等产品，同时也可提供原装进口件。

Key words: screw, pulley, the cavity, the belt.

要害词：螺杆、带轮、腔体、皮带。

C, Injection Molding: injection molding stage is the injection screw in the fuel tank thrust, in the Reserve Room of the expected melt through nozzles, mold flow, the gate into the cavity.

三，注塑充模：注射充模阶段是螺杆在注射油缸推力作用，将储料室中的熔体经过喷嘴、模具流道、浇口注入型腔。

The acid phosphetase in the blood cells of oncomelania hupensis was observed at the light microscope level by the burstone stained technique.

将解剖的钉螺软体组织经挤压法获取钉螺血淋巴液，以偶氮色素法染色后，光学显微镜下观察螺血淋巴细胞酸性磷酸酶活性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
