The aero-engine that is used on aircraft needs that periodically engine is implemented to clean, by cleaning remove into
Deposit on air flue, compressor and turbo blade protects blade, miscellaneous in air so as to delay or remove
The influence of confrontation engine performance, recovers the performance of deterioration parts, reduces the degree that parts are corroded,
Ensure engine projected life and reliability, while prevention or exclusion breakdown in the motor.
The background section of Chinese patent application 201420627804.X is to available engine cleaning technique
It is described, i.e. the mode of existing cleaning there are two kinds：Cleaning and flushing.Cleaning refers generally in hair
Motivation is cold to be turned under state, and the salinity on detergent solution cleaning blade is sprayed into engine, and cleaning also referred to as " is removed
Salt is cleaned ".Due to be engine is cold turn state under carry out, therefore desalination will not cause the heat of engine rotten
Erosion.Typically periodically cleaned.Flushing refers to engine in idling rating, and water or conjunction are sprayed into engine
Suitable cleaning agent removes the grease soils on blade, so as to recover engine performance, therefore rinses also known as " extensive
Renaturation can be cleaned ", it is rinsed after general daily very end of the train flight.
Existing aircraft maintenance uses special cleaning equipment and flushing device, and two complete equipment pipelines are not general,
Pipeline switching, operate it is all very inconvenient, and since it is desired that the pipeline such as external water source, power supply, generally all
Mobile difficult, structural volume is big, it is difficult to which with flying for flight-line service, and cleaning equipment and flushing device are each
From unitary function, applicability is wide, when single cleaning/pre-washing function is applied to temperature relatively low environment,
Also need to heat up water in addition improve water temperature, improve cleaning performance.And after the cleaning for completing engine,
The water capacity of residual easily freezes when temperature is low in engine wash system, blocks purging system, influence
The next time of purging system uses, and melts the maintenance of the influence aircraft in ice blockage region, and for difference
Use environment, lacks flexible flow and pressure regulating measure, and versatility is not strong.

Wherein, by controlling three three-way control valves, it is possible to achieve stirring, cleaning, flushing, water removal etc.
Function.Reference picture 3 is described as follows：
Agitating function：Cleaning fluid tank 411 adds distilled water or pure water and adds appropriate cleaning agent and formed
Rinse water, rinse the addition of liquid case 412 is the flushing water (distilled water or pure water) for being rinsed after cleaning.
Agitating function is that in order that form the sufficient rinse water of mixing in cleaning fluid tank 411, the solution of the present invention is,
Make that the B interface of three-way control valve K1 to C interface is connected, A interfaces are closed, then by three-way control valve K2
D interface to E interface connect, F interface is closed, and connects electronic pumping source, operation of electrically driven pump 144,
So that the rinse water in cleaning fluid tank 411 is circulated by electrodynamic pump 144 and extracted out from three-way control valve K1, so
Returned from three-way control valve K2 afterwards, repeated multiple times circulation can reach the function of stirring.
Cleaning function：After rinse water is well mixed, electronic pumping source is first closed, keep three-way control valve
The B interface of K1 to C interface is connected, the closing of A interfaces is constant, by the D interface of three-way control valve K2
Connect to F interface, E interface is closed, the G interface of three-way control valve K3 to J can be connected, H connects
Mouth is closed, and connects electronic pumping source, and engine is cleaned.
Pre-washing function：Cleaning closes electronic pumping source after finishing, and the A of three-way control valve K1 is interfaced to
C interface is connected, B interface is closed, by the D interface of three-way control valve K2 to F interface connection, E interface
Close, the G interface of three-way control valve K3 to J can be connected, H interface is closed, connect electrodynamic pump electricity
Source, is rinsed to engine.
Remove water function：Electronic pumping source is closed in flushing after finishing, interface H connects external high pressure source of the gas, will
The H interface of three-way control valve K3 to J interfaces are connected, G interface is closed, and will be cleaned using external gas source
Water in pipeline blows down, it is to avoid liquid residue goes bad, and also avoids a day cold junction ice damage equipment.
In sum, aero-engine ground washing car of the present invention can realize stirring, clean, rinse with
And remove water function, it is easily assembled with simple structure, it is maintainable good, it is easy to operate, reliability is high
