摘要: 洛克环是一种高效、可靠的管件连接技术,目前制冷行业中已经完全取代传统的氩弧焊与电阻焊技术。本文通过CAE仿真技术模拟洛克环连接铜管工艺,在18.6MPa和6.3MPa静压工况条件下分析不同铜管壁厚对连接强度的影响,分析结果表明铜管在以上两种下工况不会发生开裂,壁厚为0.6、0.7mm的管件洛克环连接存在泄漏风险,建议配管选大于0.7mm壁厚铜管。

Abstract: Lokring Ring is a very efficient and reliable connection technology of the pipes, which has completely replaced the traditional argon arc welding and resistance welding technology in the refrigeration industry. This paper used the CAE simulation technology to simulate the copper pipes connecting process by Lokring Ring, analysed the influences of the different wall thickness of the copper tubes on the bonding strength under the static pressure condition of 18.6MPa and 6.3MPa. The results show that copper will not crack with above two conditions, but there was a leak risk with the wall thickness of pipe 0.6 and 0.7mm connecting by Lokring Ring, suggested to choose the copper pipe more than 0.7mm thickness.
