Abstract
A method is provided for treating a fuel system of a turbine engine. During this method, a treatment system is connected to the turbine engine. Preservation fluid is drawn out of the fuel system using the treatment system.
Claims16
A treatment system for a fuel system of a turbine engine, the fuel system including an injector, a fuel system interface and a flow regulator fluidly coupled between the injector and the fuel system interface, the treatment system comprising:
- a control system configured to signal the flow regulator to open;
- and
- a fluid system including a fluid system interface and a pump fluidly coupled with the fluid system interface, the fluid system interface configured to fluidly couple with the fuel system interface, and the pump configured to draw fluid out from the fuel system at the injector through the flow regulator;
- wherein the pump is a first pump, and the fluid is preservation fluid;
- and
- wherein the fluid system further includes a second pump configured to prime the fuel system with fuel after the preservation fluid is drawn out of the fuel system by the first pump.
A treatment system for a fuel system of a turbine engine, the fuel system including a fuel system interface, the treatment system comprising:
- a fluid system including a fluid system interface, a pump and a container;
- the fluid system interface configured to fluidly couple with the fuel system interface;
- the pump fluidly coupled to and between the fluid system interface and the container, and the pump configured to draw preservation fluid out from the fuel system;
- and
- the container configured to receive the preservation fluid drawn out of the fuel system by the pump;
- wherein the pump is a first pump, and the fluid system further includes a second pump configured to prime the fuel system with fuel after the preservation fluid is drawn out of the fuel system by the first pump.
