汽车水冷系统由散热器(水箱)、水泵、气缸水套、缸盖水套及管路等组成,冷却水在水泵的带动下循环冷却。但是,冷却水中的Ca~(2+)、Mg~(2+)会因水分蒸发而浓缩,并生成沉淀物,沉积于水套及水箱中,从而影响水冷效果。各地水质不同,造成水套等的积垢情况也不同:在石灰岩地区,因Ca~(2+)、Mg~(2+)离子浓度高,造成积垢特别严重。此外,水中溶解氧会使碳钢材
Car water cooling system consists of radiator (water tank), water pump, cylinder water jacket, cylinder head water jacket and piping, etc. Cooling water is circulated and cooled by the pump. However, Ca2 + and Mg2 + in the cooling water will be concentrated due to the evaporation of water and generate sediments, which are deposited in the water jacket and the water tank, thereby affecting the water cooling effect. The water quality varies from place to place, resulting in different sets of fouling in water jackets. In limestone areas, the fouling is particularly severe due to the high concentration of Ca ~ (2 +) and Mg ~ (2+) ions. In addition, dissolved oxygen in water can make carbon steel
