在中亚细亚的哈萨克斯坦的南方,每年的夏季气温很高,超过了计算所取的+40℃。这样高的气温,一昼夜持续4～5小时。例如,在中亚细亚铁路的德日查卡车站,气温为十44～45℃,每年持续100个小时,而在同一铁路地区的牟巴列克车站,这一气温一年近600个小时。很明显,在这样的外界气温时,冷却装置不能保持柴油机冷却水和润滑油温度所需要的范围,因此列车不得不降低运行速度以及减少列车牵引定数。这种运营方式给国民经济带来物质上的损失,因此探求提高内燃机车冷却装置效率的问题,对中亚细亚和哈萨克斯坦铁路有其现实意义。
In Central Asia’s southern Kazakhstan, the annual summer temperatures are very high, exceeding the calculated +40 ° C. Such a high temperature, day and night for 4 to 5 hours. For example, on the Central Asia Railway’s Tejharka station, temperatures range from 44 to 45 ° C for 100 hours per year, and at Mouleluck Station in the same railroad area, the temperature is almost 600 hours a year. Obviously, at such outside temperatures, the cooling device can not maintain the required range of diesel engine cooling water and lubricant temperature, so the train has to reduce the running speed and reduce the number of train traction. This mode of operation brings about material losses to the national economy. Therefore, exploring the issue of improving the efficiency of diesel locomotive cooling units has its practical significance for Central Asia and Kazakhstan’s railway.
