摘要
某公司生产的RHU200AHZ1-N型号空气源热水机组在安装运行后,吸气铜管多次发生断裂。研究结果表明:吸气铜管发生断裂是由振动过大或共振引起的,安装问题导致压缩机与安装槽钢发生共振,加速铜管的疲劳失效,最终使吸气铜管断裂。根据分析结果确定机组安装的整改方案,整改后吸气铜管断裂故障得到排除。
When RHU200AHZ1-N type air source hot water unit produced by one company is installed and operated,the suction pipe are often broken.The research results show that the excessive vibration or resonance causes suction pipe fracture and the resonance happens between the compressor and the base channel steel,which accelerates the fatigue failure of the copper tube,as result of the installation problems,the suction pipe begins to fracture.Rectification scheme for units installation is determined according to analysis results,the suction pipe fracture failure is excluded.
