泥管的磨损机理 Wear mechanism of mud pipe 挖泥船舶可以挖掘的土质种类繁多,有石块,粗砂,中细砂,细粉砂,卵石,粘土,淤泥等,各种土质在泥管中输送中均对泥管内壁不可避免地产生着不同程度的磨损。微观状态下,流动的磨损颗粒对泥管的金属表层进行切削,使得金属被磨损颗粒剥离金属基体,随着泥管使用时间的推移, 泥管过流侧的金属被剥离程度越来越严重,直至泥管磨损损坏。 There are many kinds of soil that can be excavated by dredger, such as stone, coarse sand, medium and fine sand, fine silt, pebble, clay, mud, etc. all kinds of soil will inevitably produce different degrees of wear on the inner wall of mud pipe in the transportation of mud pipe. In the micro state, the flowing wear particles cut the metal surface of the mud pipe, so that the metal is stripped from the metal matrix by the wear particles. With the passage of the mud pipe service time, the metal on the flow side of the mud pipe is stripped more and more seriously until the mud pipe is damaged by wear. |
