Abstract

A mobile cart-mounted unit for cleaning and preserving turbine engines comprises pressurized reservoirs for holding the solvent, cleaner, preservative and water. Pressurization is achieved by use of an integrally mounted air compressor driven by an internal combustion engine. The engine also powers an alternator which is used to charge a storage battery. The storage battery serves as an energy source to crank the turbine to approximately 10 percent rated speed during the cleaning and preservation servicing sequence. A control console provides the operator with the needed valves, gages and meters with which to operate the unit.

Claims

1. Apparatus for cleaning and preservation of a gas turbine engine, said engine having a starting motor for cranking the rotary compressor stages thereof, comprising in combination:

a frame structure having supporting wheels journaled for rotation;

a first reservoir mounted on said frame, said first reservoir being partially filled with water;

additional reservoirs for cleaner, solvent and preservative solutions mounted on said frame;

an internal combustion engine, a control console, a rotary air compressor and an alternator also mounted on said frame, said internal combustion engine being drivingly coupled to both said air compressor and said alternator;

an electric storage battery mounted in a compartment of said control console;

electrical connections between said alternator and said battery for charging said battery, said electrical connections including operator-manipulated control means for controlling the energy transfer from said alternator to said battery;

fluid connection means between said air compressor and said first reservoir for pressurizing said first reservoir with a volume of compressed air;

fluid connections between said volume of air and each of said additional reservoirs for pressurizing said additional reservoirs;

manually operable controll means in each of said connections for controlling the pressurization of each of said reservoirs;

nozzle apparatus mountable on said gas turbine engine for spraying the inside thereof with fluids;

means for connecting each of said reservoirs to said nozzle apparatus, said means including a high pressure hose selectively connected to said reservoirs; and

encircuiting means including a two-conductor electrical cable connecting said battery to said starting motor for cranking said rotary compressor stages.

2. The cleaning and preservation apparatus as set forth in claim 1 wherein the encircuiting means further comprises a reverse current relay serving to automatically disconnect at least one of said two-conductor cables from said storage battery whenever current flowss reverse in said cable.

3. The cleaning and preservation apparatus as set forth in claim 1 wherein the internal combustion engine is a manually cranked five horsepower gasoline engine.

4. The cleaning and preservation apparatus as set forth in claim 1 wherein the frame structure is supported on four rotatably mounted wheels, one wheel being generally on each corner of said frame structure, the front two of said wheels being arranged for cooperative action with a T-handle steering bar.

5. The cleaning and preservation apparatus as set forth in claim 1 wherein said fluid connections between said volume of air and each of said additional reservoirs includes pressure regulators for adjusting the pressurization level at each reservoir.

6. The cleaning and preservation apparatus as set forth in claim 5 including an air supply line for purging liquids from the means connecting each of said reservoirs to said nozzle apparatus.
