几年前,我在西德KS公司学习高压造型线安装时,发现该公司液压管道的安装施工一般分两个工序进行。一个是在安装后要经酸洗(20％硫酸或盐酸)、中和(10％苏打水)、冲洗、干燥、涂油等处理。另一个是在安装前要严格清除粘浮在管子内壁上的杂物,如砂子、氧化皮、铁末、纱头等。这些杂物不仅污染液压油,加剧阀、泵相对运动表面的磨损,严重时会堵塞 A few years ago, when I was studying high-pressure molding line installation at KS West, I found that the company’s hydraulic pipeline installation and construction generally divided into two processes. One is to be pickled (20% sulfuric acid or hydrochloric acid), neutralized (10% soda), rinsed, dried, oiled, etc. after installation. The other is to strictly remove sticky floating in the pipe wall before the debris, such as sand, scale, iron, yarn and so on. These sundries not only contaminate the hydraulic oil, exacerbate the valve, the relative movement of the pump surface wear and tear, in serious cases will be blocked
