这些气 穴通常由具有格外高能量的水蒸气所填充，与混凝土表面的反复接触导致形成凹陷和孔洞，即气蚀。既然高质混凝土也不能抵抗这种劣化，因此最好的补救是通过制造平滑水流来消除气蚀。在所有必须的地方，关键的面上衬以高抗气蚀性的材料。通常，混凝土抗腐蚀和磨损的能力随强度增加而提高。采用硬韧的集料可改善混凝土的抗磨损性。

Porous asphalt concrete is composed of asphalt mastic, coarse aggregate, thin aggregate, stuff and admixture. Such a combination is expected to fully integrate these materials. In this way, the function of interlocking among particles can be performed, a firm net of porous asphalt framework formed and the ability to resist rut and wear developed. The different mixture results in different effects; the quality is so complicated that the factors that cause damage are multiple. Therefore, it is bothersome to choose one material that can be adjusted to various conditions everywhere, such as the traffic volume, load and the weather. The current study mainly investigates and analyzes the main factor that caused flaws after the roads paved with porous asphalt concrete have been open. The analysis aims to search for the best solutions, promote the quality, prolong its availability and finally reach the purpose of complete use.

多孔隙沥青混凝土依其组成材料由沥青胶泥、粗粒料、细粒料、填充料、添加物等组成，目的是希望藉由以上材料的组合能充分接触，发挥颗粒间互锁作用，形成牢固的连锁网的沥青混凝土架构，发挥粒料本身良好的抗车辙及抗磨损之能力，因添加物的不同所发挥出的效果亦不同，其性质甚为复杂，造成损坏之因素亦属多重性，要择其适用於各地迥异之各种条件，如交通量、荷载及气候环境等因子，极为繁琐，本研究主要探讨及分析已铺筑之多孔隙沥青混凝土铺面，经通车后产生之缺失主要因素，以寻求其最佳解决方案，提升品质与延长使用寿命，进而达到全面使用。

The Circulation-hydrogenation Compressor Model BLC-305/A is an important equipment with Hydrogenation devices, which is imported by Lanzhou Petrochemical Company Refinery. Due to high-speed rolling periodically, the spare parts of this compressor, to a varying extent, show a lot of signs of wear and tear. Especially, the axle sleeve of the rotor axle of the compressor is so worn to the greatest degree that its work efficiency decreases by a big margin. Machinery Factory of Lanzhou Petroleum Processing and Chemical Complex has undertaken this task to repair the rotor.

The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.

轴颈和轴瓦的装配间隙太小，还有机油压力低是影响润滑效果的关键指标，使得曲轴和轴瓦之间因缺少机油润滑而咬死失效，包括严重拉伤，缺少润滑油，干摩擦产生合金层熔化，磨滑面没有保持一定厚度的油膜，以及各种局部过载疲惫破坏，气蚀和V形破坏等，通过本人主管内燃机车技术多年经验及对其故障原因的分析，特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂，导致轴瓦和曲轴产生摩擦，在高温、高压和高转速下，轴瓦的耐磨合金层过早地磨损或熔化，从而引起轴瓦和曲轴粘咬，会使轴瓦的钢背和座孔中产生旋转运动，进油孔被堵塞，再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏，并会造成螺栓折断，发生甩出捣坏内燃机缸体的恶性事故。
