单仓泵使用的一点改进

我厂单仓泵的结构示意见图１。助吹管道能够有效地帮助喷射系统完成送料工作，缩短送料时间。但由于助吹管道所处位置偏低，很容易被结块水泥堵塞。我们对其作适当改造，用高压橡胶管代替原来的钢管，利用橡胶管的弹性，在工作中一涨一缩，可以有效地防止水泥结块，取得较好的效果。经过一段时间的使用，助吹管的堵塞时间由原来的１５d左右延长至约６０d，延长了维修周期。单仓泵使用的一点改进@袁礼军$大湖水泥厂!江苏徐州221004 @孟庆雷$大湖水泥厂!江苏徐州221004     

浅议转向球的最佳直径及其安装

1转向球最佳直径的选择在气力输送管道系统中，以转向球代替弯头，既能减少混和料流对转向处管道的冲刷磨损，又方便料流的转向和多路分支。但是，若转向球直径选择过大，既不利于制作和安装，而且在转向球处由于管径突然增大，料流速度降低过多，可能会造成物料在转向球内沉积，若转向球直径选择过小，那么转向球的作用很难体现出来。因此，就如何选择转向球直径，笔者认为下面方法可供参考。根据实际气力输送系统的相关参数，计算出料流在管道内的实际流速，然后令料流在转向球内的流速为物料的浮送速度，从而得知转向球的最佳直径。现以…     

刮板输送机衬板小改革

刮板输送机衬板小改革袁礼军江苏省徐州大湖水泥厂（２２１００４）刮板输送机的铸石衬板多数是采用水泥砂浆粘贴在机壳内，在运行中由于振动很容易脱落。笔者也曾看到有些使用者采用圆钢代替铸石衬板，但这样一方面会导致刮板的不均匀磨损，再者圆钢的耐磨性也远不如铸石...     

延长高细磨隔仓筛板寿命的小措施

我厂于１９９６年建成投产的一条１０万ｔ水泥生 产线,水泥粉磨选用２．２ｍ×７．５ｍ微介质高细磨, 其隔仓板是由支架、筛板、一仓护板、二仓护板４部分 组成（见图１）,一仓护板间有１５～２０ｍｍ左右的缝 隙,护板和筛板间有约４０ｍｍ左右的间隙。 在运转中我们发现,每隔月余,筛板和一仓护板 间空隙常被异物堵死（多数是破碎的钢球和熟料）,导 致饱磨．清理时还发现,筛板上靠近护板凸台周围破 损、漏洞较多,使大量大块熟料进入二仓。更换一套筛 板约需维修费用２０００元。 分析原因认为：（１…     

Effects of trace addition of vanadium and depression amount on recrystallization temperature and mechanical performance of 5182 belts

Because the mechanical performances of 5182 belts used for carbonated drinks cover decrease after baking, the effects of trace addition of V and depression amount-in last step on microstructure and properties of 5182 belts were investigated. The microstructure, mechanical performances and recrystallization temperature of 5182 belts and 5182V belts in different steps were analyzed comparatively with metallographic microscope, micro-hardness tester, electron universal materials test machine and differential thermal analyzer. The results show that the mechanical performances of the belts are remarkably improved by the trace addition of V and the reduction of depression amount in last step. In addition, the recrystallization temperature of the belts is also increased but not obviously. As the precipitation of V is not full, there are not enough disseminatedly distributed particles, and the recrystallization temperature increases little. However the solution strengthening and the fine grain strengthening are enough to improve the mechanical performances to satisfy customer requirements. The effects of reduction of depression amount in last step on mechanical performance were explained in view of energy. Moreover, the strengthening mechanism of V-compound interlocking grain boundary was also discussed.
