Research And Optimum Design Of Car Dumper System

Car dumper system, a very specialized complete set of equipments, is used to handle bulk materials from trains. With continuous development of national economy, industrial fields including thermal power plants, metallurgical plants, cement mills, habours and mines are now growing in full swing, that leads to massive increase of consumption of bulk materials like coal, coke and ore conveyed by trains, which leads to an annual demand of 50-60 sets of car dumpers. Whereas the processing set-up, product design and testing are responsibilities of different industrial units respectively, there have been in short of system study on car dumper system to optimize its integrated performance in the history. Therefore, this is selected as the research subject.This article comprises threes parts. Part one presents system research and optimizaiton of technological parameters and equipment parameters. The most important performance index of car dumper system is integrated handling efficiency which depends upon system technological parameters and technical parameters of subsidiary equipments. The technological parameters can be optimized through research on layout relations between wheel gripper, dumper, traverser, ejector etc. The equipment parameters can be optimized through study on performance indexes of each equipment. By means of such researches the integrated handling efficiency of the system can be greatly improved while equipment cost and civil construction cost can be reduced considerably.Part two presents research on adaptability of wagons. The operationg process of car dumper system is an interaction process between wagons and car dumper system. Before the system being put into operation, professional test authority conducts an overall test as per relevant standards and regulations issued by Ministry of Railway. Based on the standards and regulations, this article advances a proposal on how to renovate and perfect all equipments of 400 sets of various types of car dumper systems currently operating within China.Part three gives engineering design examples. Car dumper system for Zhejiang Zheneng Lanxi Power Plant is the first tandom car dumper system domestically developed and designed within China, among which the subsidiary tandom traverser is the first one developed in the world. Based on engineering practices, this article combines with conclusion drawn from system research and optimization, presents the engineering design which henceforth provides theoretical basis for the design and type selection of car dumper systems.
