请帮忙翻一下:Turbo expander
The expansion turbine is of the radial inflow type with advanced aerodynamic
design maximizing the isentropic efficiency. The machine is of a proven
cartridge concept which allows a quick replacement of the machinery capsule
including the rotating parts without interference with the expander cold
insulated process pipes.
The atmospheric lube oil return lines from the cartridges
to the reservoir close the loop.
