A device for engine cleaning

Abstract

The invention relates to a device for cleaning an engine. The device is used for washing and / or flushing aeroengines by using water and a detergent. The device for cleaning the engine comprises a mobile vehicle frame, of which the bottom is provided with universal wheels, wherein the vehicle frame has a collapsible handle, and a liquid storage tank, a liquid path control box, an electrical control box, an electric pump, a gas pressure release device, a pipe reeler and a storage box are detachably arranged on the vehicle frame. The device for cleaning the engine, provided by the invention, is simple in pipeline, convenient and reliable in connection, small in size of each component and light in weight and can be very conveniently dismounted and mounted, so that the device can be conveniently carried over and redeployed along with aeroplanes, and a clean-out operation on the engines can be guaranteed at any time during flight-line maintenance.

Description

technical field [0001] The invention relates to a device for cleaning an aircraft engine, in particular to a device for cleaning an engine. Background technique [0002] The aero-engines used on aircraft need to be cleaned regularly to protect the blades by cleaning and removing the deposits on the air intake, compressor and turbine blades, so as to delay or remove the impact of impurities in the air on the performance of the engine and restore the performance of deteriorated parts , reduce the degree of corrosion of parts and components, ensure the design life and reliability of the engine, and prevent or eliminate engine failures at the same time. [0003] The background technology part of Chinese patent application 201420627804.X describes the existing engine cleaning technology, that is, there are two existing cleaning methods: cleaning and flushing. Cleaning generally refers to spraying a detergent solution into the engine to clean the salt on the blades when the engin...

AI Technical Summary

Problems solved by technology

[0004] Existing aircraft maintenance uses special cleaning equipment and flushing equipment. The pipelines of the two sets of equipment are not common, and it is very inconvenient to switch and operate the pipelines. Moreover, it is usually difficult to move because of the need for external water sources, power supply and other pipelines, and the structure is large. , it is difficult to use for field maintenance, and the cleaning equipment and flushing equipment have a single function and are not widely applicable. cleaning effect

And after the engine cleaning is completed, the residual water in the engine cleaning system is easy to freeze when the temperature is low, blocking the cleaning system and affecting the next use of the cleaning system, and for different use environments, there is a lack of flexible flow and pressure adjustment means , the versatility is not strong
