一、总体方案设计阶段的机型选择问题依据国内外有关技术资料介绍,并对国内具有相类似生产性质的设备进行调查研究,分析对比,我们认为设计生产能力要求在1000～2000米~3/小时、排料臂长度在30～40米范围内的排土机采用图1a 的机型是趋于合理的。PS-1000排土机采用了这种机型。 First, the overall program design stage of the model selection problem According to the introduction of relevant technical information at home and abroad, and the domestic production of similar nature of the equipment to conduct research, analysis and comparison, we believe that the design and production capacity requirements in the 1000 ~ 2000 m ~ 3 / H, the discharge arm length in the range of 30 ~ 40 m dumper using Figure 1a models tend to be reasonable. PS-1000 earth mower used this model.
