| Abstract: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. |
