走出研究柴油机气缸套磨损问题的误区 总被引:2,自引:0,他引:2
通过对RLB56柴油机的调查与试验,了解到气缸套损坏过程及其特点。文章突破现有理论的局限,走出思维定势的误区,首次提出一种新的低速柴油机气缸套磨损模式--撞击磨损模式,同时指出:解决撞击磨损的问题,不能通过提高气缸套的材质和润滑油粘度加以解决,而是应该改变柴油机有关部件的结构设计。 相似文献

The effect of the circulation fan installed in fresh food compartment on energy consumption of natural convective refrigerator/freezers (RFs) was experimentally studied. Five different RF models with different cycles were tested. The experimental results showed that the energy consumption of the single-loop cycle RF increased by 2.4%~3.8%, that of the bypass two-circuit cycle RF decreased by 1.0%, and that of the two-circuit cycle RF with its evaporators in parallel when the geometry parameters of refrigeration system and the refrigerant charge were not changed after the circulation fan was installed decreased by 3.3%. When the optimization on the refrigerant charge and the evaporator was carried out, the energy consumption of the single-loop cycle RF , the bypass two-circuit cycle RF and the two-circuit cycle RF with its evaporators in parallel, decreased by 1.0%~6.4%, 3.25% and 3.26% respectively. The present conclusions will provide a guideline to the optimum design for the RF with the circulation fan. 相似文献
