在氣動(dòng)輸送系統中輸送散裝物料的過(guò)程中，最容易出現故障的是氣動(dòng)輸送管道的磨損。有時(shí)，設備的嚴重性會(huì )導致整個(gè)設備停機，因此機械師和設計人員必須不斷地進(jìn)行改進(jìn)。改進(jìn)的技術(shù)提高了氣動(dòng)輸送系統的耐磨性，并確保了系統的平穩運行。

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.

經(jīng)驗表明，氣動(dòng)輸送管的磨損與空氣輸送速度，所輸送貨物的磨損，散裝物料的濃度，管道的直徑以及管道中使用的物料有關(guān)。直線(xiàn)和拐角的磨損明顯不同。對于某些輸送材料，彎頭的使用壽命只有幾個(gè)小時(shí)，而相同材料的直截面鋼管的使用壽命只有幾個(gè)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，水平管的磨損也不均勻，下部磨損比上部磨損更嚴重。因此，建議在最大通過(guò)時(shí)間后，將帶凸緣的厚壁管旋轉90度。管道的安裝過(guò)程應正確，軸線(xiàn)不得偏斜，并且不允許從大孔到小直徑孔的過(guò)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.

帶限位連接的法蘭是管道裝配的最佳選擇。當管道磨損最大時(shí)，可以使用專(zhuān)用管道代替傾斜管道，因為它比水平管道和直管磨損得更快。關(guān)于肘部的選擇，原則是穿厚壁或簡(jiǎn)單地替換最簡(jiǎn)單的肘部位置，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.
