我国装载机行业目前配套件的基本情况是;生产企业多,多数规模小,很零乱。中型轮式装载机配套件较成熟,数量充足,但水平较低,质量及可靠性问题较多。大型及小型装载机的配套件较缺。 1.发动机 目前国内装载机所用发动机主要是6135系列柴油机。该柴油机从国产装载机诞生开始,直到现在还占主导地位。但该柴油机故障率已经占到整机故障率的一半以上,用户已怨声载道。目前对柴油机的要求归纳起来有五点:第一可靠性要求高;第二油耗率、噪声、排放指标要低;第三起动性能要好;第四要求结构紧凑、外型美观;第五要求配件供应充足,维修服务及时。 目前已经给装载机批量配套的新柴 China’s loader industry is currently supporting parts of the basic situation is; more manufacturing enterprises, most small-scale, very messy. Medium-sized wheel loaders matching more mature, a sufficient number, but the level is low, quality and reliability issues more. Large and small loaders lack of accessories. 1. Engine At present, the engine used in domestic loaders is 6135 series diesel engine. The diesel engine from the birth of homemade loaders, until now still dominate. However, the failure rate of the diesel engine has accounted for more than half of the failure rate of the machine, the user has complained. The current requirements of the diesel engine summed up in five points: the first high reliability requirements; the second fuel consumption rate, noise, emission targets to be low; the third starting performance is better; the fourth requirement of compact structure, good looks; fifth requirement accessories Adequate supply, timely maintenance services. Loads have been given to the new batch of Chai
