    装载机治理过热的原则有哪些?
    发布时间:2015-5-30 10:51:52    浏览:197次

    装载机治理过热的目标是减少发热、合理散热和实现热平衡,治理时可遵循如下的原则。

    1、全方位原则。装载机热平衡是一项系统工程,若出现过热和过冷故障,必须从发热源、散热源和热平衡等全方位分析原因并制定维修对策。
    Shandong loaders heat balance is a systematic project, if there is excessive heat and cold fault, must develop maintenance strategies from the comprehensive analysis of the reasons the heat source, heat source and heat balance and.

    2、顺序原则。在分析装载机过热原因时,建议采用如下顺序原则:环境温度→操作→发热源→散热源→综合分析和治理。采用顺序原则可保证发现问题早、查找问题准、治理效果好。
    In analyzing the cause of the overheating, Shandong loaders, proposed the following principle of order: Ambient temperature heat source → operation → → → heat source comprehensive analysis and management. Using the principle of order can be guaranteed to identify problems early, find the problem potential, good treatment effect.

    3、防假原则。装载机汽缸体、汽缸盖有裂纹以及汽缸垫密封失效,都会使汽缸内的气体进入冷却水道,引起水散热器中的冷却水未到沸点而沸腾;高原地区气压低,水散热器的冷却水也会出现未到沸点即沸腾现象;另外,温度传感器失效会将水温、油温误报。因此,在分析过热原因时应认真分析,防止误判。
    Shandong loaders cylinder block, cylinder head and cylinder head gasket sealing cracks failure will cause the gas cylinder into the cooling water, causing the water in the radiator cooling water not yet reached the boiling point and boiling; plateau pressure is low, the cooling water radiators That is not yet reached the boiling point of water will also appear boiling phenomenon; In addition, the temperature sensor failure will be the water temperature, oil temperature false positives. Therefore, we should analyze the cause of overheating in a careful analysis, to prevent miscarriage of justice.

    4、改进原则。近年来,装载机普遍采用高效、低耗柴油机,同时采用按需调速的独立式液压驱动风扇和新材质散热器,所以对老旧山东装载机发热源和散热源系统进行维修时,建议采用新技术对老旧工程机械进行技术改进,以实现最佳热平衡。
    When recent years, Shandong loaders widely used efficiency, low consumption diesel engine, while the on-demand governor's independent hydraulic driven fan and radiator new material, so the old Shandong loaders heat source and heat source systems for maintenance, it is recommended adoption of new technologies on old machinery for technical improvements to achieve optimum thermal equilibrium.
