摘要
柱塞泵配流盘-缸体摩擦副在柱塞泵的运行之中导致的运行磨损及磨损产生的异物二次磨损是影响配流盘-缸体使用寿命的重要因素。采用激光加工技术在配流盘常用基础材料59黄铜表面加工微织构。在中科凯华CFT-1摩擦磨损机上,选用常见缸体基础材料45钢以面-面接触形式分别对有织构和无织构的配流盘-缸体摩擦副试样在干磨擦与混合摩擦(润滑)条件下的摩擦磨损性能进行了试验。分析了不同织构参数在不同摩擦条件下对试样摩擦磨损的影响。结果表明:织构必须在混合摩擦条件下才能产生减摩效应;与未加工织构的铜合金试样表面相比,合理的织构参数可使织构在液压工况条件下稳定留存,并发挥其减摩作用,使磨损量显著降低。
The operation wear caused by the friction pair of valve plate and cylinder block in the operation of piston pump and the secondary wear caused by the wear are the important factors affecting the service life of valve plate and cylinder block. Laser processing technology was used to process the micro-texture on the surface of 59 brass, which was a common basic material of the valve plate. On the Zhongke Kaihua CFT-I friction and wear machine, the common cylinder base material45 steel was used to conduct dry friction. The friction and wear performance under mixed friction(lubrication) conditions were tested. The influence of different texture parameters on the friction and wear of the sample under different friction conditions was analyzed. The results show that the texture must be under mixed friction conditions to produce the anti-friction effect. Compared with the unprocessed texture of the copper alloy sample surface, the reasonable texture parameters can make the texture stable and retained under hydraulic conditions, which can play its anti-friction effect, so that the amount of wear significantly reduces.
