舰用40Mpa高压空气系统铜合金接头研究

高压空气接头是舰艇高压空气系统的重要连接件,随着系统压力级提升至40 MPa,标准接头不再适用,需要研究一种高压力级的接头.本文从在役舰艇高压空气接头使用问题出发,从部件材料匹配、密封结构和控制操纵力矩的角度开展了舰用40 MPa高压空气接头研究工作,通过仿真计算、样机试制和样机试验等方法,对研制的40 MPa铜合金接...

Research on copper alloy joints in 40 MPa high pressure air system for ships

High-pressure air joint is an important connecting component of the high-pressure air system for ships,as the system pressure level increases from 20 MPa to 40 MPa,the standard joint used in the original system is no longer suitable.Therefore,a new high-pressure joint needs to be researched to meet the requirements of 40 MPa system.Starting from the use problem of high-pressure air joints for in-service ships,the research work was carried out on the 40 MPa high-pressure air joint for ships for the angle of the material matching,seal structure and operating torque control.Through simulation calculation,prototype trial manufacture and test,a new type of 40 MPa copper alloy high-pressure air joint for ships was developed,and design check and performance verification were carried out for them.The test results show that the strength,tightness,burst test and tear-off test of the developed joint all can meet the system use requirements,which lays a foundation for the successful application of the 40 MPa high-pressure air system for ships.
