Tips for improving the wear resistance of pneumatic conveying system pipes

有人說，氣力輸送系統(tǒng)是完善的，可以解決粉塵污染問題，可以有效地完成生產(chǎn)運(yùn)輸工作。它是輸送設(shè)備中理想的粉末輸送系統(tǒng)，但黃金并不。無論是設(shè)備還是人，它都不會(huì)真正。

Some people say that the pneumatic conveying system is perfect, which can solve the problem of dust pollution and effectively complete the production and transportation work. It is an ideal powder conveying system in conveying equipment, but gold is not perfect. Whether it is equipment or people, it will not be really perfect.

在氣動(dòng)輸送系統(tǒng)中輸送散裝物料的過程中，容易出現(xiàn)故障的是氣動(dòng)輸送管道的磨損。有時(shí)，設(shè)備的嚴(yán)重性會(huì)導(dǎo)致整個(gè)設(shè)備停機(jī)，因此機(jī)械師和設(shè)計(jì)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(tǒng)的耐磨性，并確保了系統(tǒng)的平穩(wěn)運(yùn)行。

In the process of conveying bulk materials in pneumatic conveying system, the wear of pneumatic conveying pipeline is easy to occur. Sometimes, the severity of the equipment will lead to the shutdown of the whole equipment, so the machinist and designer must constantly improve. The improved technology improves the wear resistance of the pneumatic conveying system and ensures the smooth operation of the system.

經(jīng)驗(yàn)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)。直線和拐角的磨損明顯不同。對(duì)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 transported goods, the concentration of bulk materials, the diameter of the pipes and the materials used in the pipes. The wear of straight lines and corners is obviously different. For some conveying materials, the service life of elbows is only a few hours, while that 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(yán)重。因此，建議在大通過時(shí)間后，將帶凸緣的厚壁管旋轉(zhuǎn)90度。管道的安裝過程應(yīng)正確，軸線不得偏斜，并且不允許從大孔到小直徑孔的過渡。

Due to the effect of gravity, the wear of the horizontal pipe is also uneven, and the wear of the lower part is more serious than that of the upper part. Therefore, it is recommended to rotate the flanged thick walled pipe 90 degrees after a large pass time. The installation process of the pipeline shall be correct, the axis shall not deviate, and the transition from large hole to small diameter hole is not allowed.

帶限位連接的法蘭是管道裝配的佳選擇。當(dāng)管道磨損大時(shí)，可以使用專用管道代替傾斜管道，因?yàn)樗人焦艿篮椭惫苣p得更快。關(guān)于肘部的選擇，原則是穿厚壁或簡(jiǎn)單地替換簡(jiǎn)單的肘部位置，并且使用特殊的耐磨材料通常非常好。

Flange with limit connection is a good choice for pipe assembly. When the pipe wear is large, special pipe can be used instead of inclined pipe, because it wears faster than horizontal pipe and straight pipe. As for the selection of elbows, the principle is to wear thick walls or simply replace simple elbow positions, and it is usually very good to use special wear-resistant materials.
