在生产氮肥的活塞式压缩机的运转过程中,存在缸套损坏的情况,并且发现其中有一些缸套极度磨损,这就使运转期受限制。90％的缸套损坏发生在压入部份和自由部份之间的过渡凸边处,而10％的损坏发生在供送润滑剂的径向孔处。缸套材料为灰铸铁和12 X 18 H10T不锈钢。 During the operation of the piston compressor producing nitrogen fertilizer, there was a condition where the cylinder liner was damaged, and some of the cylinder liner was found to be extremely worn, which limited the operation period. Ninety percent of the cylinder liner damage occurs at the transition flange between the press-in part and the free part and 10% damage occurs at the radial hole where the lubricant is supplied. The liner material is gray cast iron and 12 X 18 H10T stainless steel.
