在气动输送系统中输送散装物料的过程中，最容易出现故障的是气动输送管道的磨损。有时，设备的严重性会导致整个设备停机，因此机械师和设计人员必须不断地进行改进。改进的技术提高了气动输送系统的耐磨性，并确保了系统的平稳运行。

The most prone to malfunction during the transportation of bulk materials in pneumatic conveying systems is the wear and tear of pneumatic conveying pipelines. Sometimes, the severity of the equipment can cause the entire device to shut down, so mechanics and designers must constantly make improvements. The improved technology enhances the wear resistance of the pneumatic conveying system and ensures its smooth operation.

经验表明，气动输送管的磨损与空气输送速度，所输送货物的磨损，散装物料的浓度，管道的直径以及管道中使用的物料有关。直线和拐角的磨损明显不同。对于某些输送材料，弯头的使用寿命只有几个小时，而相同材料的直截面钢管的使用寿命只有几个月。

Experience has shown that the wear of pneumatic conveying pipes is related to the air conveying speed, the wear of the transported goods, the concentration of bulk materials, the diameter of the pipeline, and the materials used in the pipeline. The wear on straight lines and corners is significantly different. For certain conveying materials, the service life of elbows is only a few hours, while the service life of straight section steel pipes of the same material is only a few months.

由于重力的作用，水平管的磨损也不均匀，下部磨损比上部磨损更严重。因此，建议在最大通过时间后，将带凸缘的厚壁管旋转90度。管道的安装过程应正确，轴线不得偏斜，并且不允许从大孔到小直径孔的过渡。

Due to the effect of gravity, the wear of the horizontal pipe is also uneven, with the lower part experiencing more severe wear than the upper part. Therefore, it is recommended to rotate the thick walled pipe with flanges 90 degrees after the maximum passage time. The installation process of the pipeline should be correct, the axis should not deviate, and it is not allowed to transition from a large hole to a small diameter hole.

带限位连接的法兰是管道装配的最佳选择。当管道磨损最大时，可以使用专用管道代替倾斜管道，因为它比水平管道和直管磨损得更快。关于肘部的选择，原则是穿厚壁或简单地替换最简单的肘部位置，并且使用特殊的耐磨材料通常非常好。

Flanges with limit connections are the best choice for pipeline assembly. When the pipeline wears out the most, specialized pipelines can be used instead of inclined pipelines because they wear out faster than horizontal and straight pipelines. The principle for selecting elbows is to wear thick walls or simply replace the simplest elbow position, and using special wear-resistant materials is usually very good.
