供给内燃机车冷却系统非优质水可能是急剧形成水垢和活性腐蚀物质的原因。根据1983年6月26日颁布的ЦТЧС—50规程规定,必须采用脱盐水来冷却柴油机,这种水现在是用离子交换法取得。最广泛的是单级阳离子交换,此法能消除水中的Ca~(2+)离子和Mg~(2+)离子,同时使水饱和Na离子和富集溶解氧。但是在这种情况下不能消除引起金属腐蚀的阴离子酸根SO_4~(2-)和Cl~-,促使形成难溶的水垢的SiO_3~2。
Supply of Diesel Locomotive Cooling Systems Non-premium water may be the reason for the rapid formation of scale and reactive corrosives. According to ЦТЧС-50 regulations promulgated on June 26, 1983, desalinated water must be used to cool diesel engines, and this water is now obtained by ion exchange. The most widespread one-stage cation exchange, this method can eliminate the water Ca 2+ and Mg 2+ ions, while water Na ions and enrichment of dissolved oxygen. However, in this case, it is not possible to eliminate the SO 4- (2-) and Cl ~- anion anions that cause metal corrosion, resulting in the formation of SiO 3 ~ 2 with insoluble scale.
