我公司有17台进口小松D31A-16型和D31E-18型推耙机。由于机龄长,作业货类为有腐蚀性的散矿,推耙机工作液压系统的很多液压钢管锈蚀穿孔,经过多次焊补后,有的已无法修理。我们试用国产胶管替代钢管,效果不错。1.替代理由功能相当。如果所选用的高压胶管的内径和额定压力能满足使用要求,那么对机器性能的影响不大。维修方便。位置复杂的钢管漏油时,必须把它周围的液压钢管也拆掉才能焊补。相比之下,高压胶管具有一定的柔软性,可以像细绳一样从机器部件
My company has 17 imported Komatsu D31A-16-type and D31E-18-type push rake. Due to the long machine age and the operating cargoes are corrosive scattered ore, a lot of hydraulic steel pipes in the working hydraulic system of the raking machine are corroded and perforated. After several times of welding, some of them can not be repaired. We try to replace domestic steel hose, the effect is good. 1. Alternative reason function quite. If the selected high-pressure hose diameter and pressure rating to meet the requirements, then the performance of the machine has little effect. Easy to maintain. Complex position of the steel pipe leakage, it must be around the hydraulic steel pipe can be removed in order to repair welding. In contrast, high-pressure hose has some flexibility, can be the same as the string from the machine parts
