摘要
为了满足不同型号舰用燃气轮机燃油系统及滑油系统的油封需求,设计了一种通用型舰用燃气轮机油封装置。通过更换不同接口型式的供油软管即可实现对不同型号燃气轮机运转或非运转状态下的内部油封。采用理论计算和数值仿真2种方法,分别评估了电加热器将160 L滑油从常温加热至脱水温度的时间,其中,数值仿真的边界条件设置与实际工况更接近,可以代表实际的加热时间。结果表明:采用理论计算和数值仿真方法得到的加热时间为分别为1800、1918 s,二者仅相差118 s(约6.56%),较为吻合,验证了采用理论计算进行电加热器设计选型的有效性;设计的油封装置自动化程度高,可实现循环过滤、加热脱水、冷却保温及油封的一键操作,缩短油封准备时间,极大提高油封效率,同时保证了燃气轮机油封效果,显著延长贮存时间。
In order to meet the preservation requirements of the fuel system and lubricating oil system of different types of marine gas turbines,a universal preservation device for marine gas turbines was designed.By replacing oil supply hoses with different types of fitting,internal oil seals can be installed for different types of gas turbines in operating or non-operating conditions.Two methods,theoretical calculation and numerical simulation,were used to evaluate the time taken by the electric heater to heat 160L of lubricating oil from normal temperature to dehydration temperature.Among them,the boundary conditions of numerical simulation are closer to the actual working conditions,which can represent the actual heating time.The results show that the heating time obtained by theoretical calculation and numerical simulation methods are 1800 and 1918 seconds respectively,with a difference of only 118 seconds(about 6.56%)between the two,which is quite consistent,verifying the effectiveness of using theoretical calculation for the design and selection of electric heat⁃ers.The designed preservation device is highly automatic,which can achieve one-click operation of circulating filtration,heating and dehydration,cooling and insulation,and preservation,it shortens preservation preparation time,greatly improves preservation efficiency,ensures the effectiveness of gas turbine preservation,and significantly extends storage time.
