| 摘 要： | 能源塔中由于载冷剂存在腐蚀性,会对回路系统中的金属材料产生侵蚀而大幅降低能源塔的使用寿命,为了保障能源塔中设备的长寿命运行,需要明确能源塔回路系统材质与载冷剂的腐蚀兼容性。 本文对能源塔回路中常用的H65铜合金、3003铝合金和20#低碳钢3种材料在6种典型载冷剂中的腐蚀行为进行了研究,结果表明,H65铜合金与YH6830、3003铝合金与BL3500载冷剂、20#低碳钢与HG3500、YH6830型载冷剂搭配使用时腐蚀控制最为理想,对延长能源塔设备运行寿命具有指导意义。

| Abstract: | Coolants corrode the metals in the circulation system and decrease the service life of energy tower significantly. To ensure the long life service of the equipments in energy tower, the corrosion compatibility between the materials in the circulation system of energy tower and the coolants should be confirmed. Herein, the corrosion behavior of H65 copper alloy, 3003 aluminium alloy and 20# low carbon steel in six typical commercial coolants was studied. The alliances between H65 copper alloy and YH6830 coolant, 3003 aluminium alloy and BL3500 coolant, 20# low carbon steel and HG3500 or YH6830 coolants are found to be optimal for corrosion control. This is significant for prolonging the service life of energy tower equipment. |
