发电机组铜水箱和铝水箱使用区别

返回 2023.09.25 来源: 0
市面上很多柴油发电机组好多都采用铝水箱材质,我们都知道铝水箱在导热性上不及铜水箱,那么在使用寿命上究竟哪个长呢?是不是铝的熔点低就会影响使用寿命呢?铜的熔点为1084.4℃,铝的熔点为660.4 ℃,但由于柴油发电机组中含有过热保护装置,所以根本不会达到这个温度,反而高温的水对水箱的寿命才是起决定作用的。
Many diesel generator sets on the market use aluminum water tank materials. We all know that aluminum water tanks have lower thermal conductivity than copper water tanks, so which one has a longer service life? Is the low melting point of aluminum affecting its service life? The melting point of copper is 1084.4 ℃, and the melting point of aluminum is 660.4 ℃. However, due to the inclusion of overheating protection devices in diesel generator sets, this temperature will not be reached at all. On the contrary, high-temperature water plays a decisive role in the lifespan of the water tank.

The water in our daily lives is not pure water, which contains various ions, especially chloride ions with high concentrations. When copper comes into contact with active ions such as Cl - and SO42- in the water, it will produce reaction products containing these active ions locally and form acids with the water. The dissolution of SO2, CO2, and H2S in the air in water can also reduce local pH values. Invading the copper will accelerate its corrosion, causing pitting corrosion inside the copper water tank and copper hot water pipe.

Aluminum water tanks cannot escape the erosion of water, as Cl - can damage the protective film of aluminum. Cl - penetrates into the protective film through small pores or defects on the aluminum surface, causing the protective film on the aluminum surface to become colloidal and dispersed. The Al2O3 protective film undergoes hydration and becomes hydrated oxide, reducing its protective effect. Moreover, the Cu2+generated after copper parts are corroded will accelerate the pitting corrosion of aluminum. In addition, SO2 in the air is adsorbed by the water film on the aluminum surface, dissolved to generate H2SO3 (sulfite), and reacts with oxygen to generate H2SO4, which corrodes the aluminum surface.
当扩散和穿透力极强的颁濒-把铝保护膜破坏后,厂翱2-再次与铝基体接触,发生腐蚀。如此循环,更加重了铝的腐蚀。由于铝的腐蚀电位序远高于铜,所以在水等电解质的作用下,铝与这些金属接触时,形成电偶,铝为阳极,受到电偶腐蚀,会更快的加重铝的腐蚀。所以铝水箱在寿命上仍然没有铜水箱使用寿命长。

Aluminum serves as the anode and is subjected to galvanic corrosion, which will accelerate the corrosion of aluminum. So aluminum water tanks still have a longer lifespan than copper water tanks.
