Multifunctional aero-engine cleaning machine

Abstract

The invention discloses a multifunctional aero-engine cleaning machine. The multifunctional aero-engine cleaning machine comprises an electric power device, a control device, a water inlet device, a filtering device, a storage device and a mixing cleaning device. The control device and the electric power device are connected electrically. The control device comprises a PLC controller, a liquid level controller, a flow detector and a pressure detector. The water inlet device is connected with the filtering device through a pipeline. The storage device comprises a water storage tank and a solvent box. A water inlet of the water storage tank is connected with an ultrapure water pump. A cleaning solvent is stored in the solvent box. The mixing cleaning device comprises a cleaning box I and a cleaning box II. A water inlet of the cleaning box I is connected with the water storage tank and the solvent box. A water inlet of the cleaning box II is connected with the water storage box. The multifunctional aero-engine cleaning machine can clean an engine by adopting two ways of clear water cleaning and cleaning solvent cleaning, all the devices are automatically controlled by adopting the PLC controller, the mixing proportion of the clear water and the cleaning solvent can be adjusted according to actual demands, manual operation is replaced, and the automation level is improved.

Description

technical field [0001] The invention relates to the field of aero-engine cleaning equipment, in particular to a multifunctional aero-engine cleaning machine. Background technique [0002] Aviation engine cleaning refers to the cleaning of the engine on a regular basis or depending on the situation, and protects the blades by removing the deposits on the air intake, compressor and turbine blades, thereby delaying or removing the impact of impurities in the air on engine performance and reducing the risk of components. The degree of corrosion ensures the design life and reliability of the engine, and at the same time prevents or eliminates certain faults of the engine. The cleaning requirements of aircraft engines are very high, especially the water quality requirements for cleaning are very high. Tap water needs to be filtered and purified before use. The existing cleaning methods include: cleaning, which generally refers to spraying Cleaning is also called "de-salting clean...

AI Technical Summary

Problems solved by technology

[0003] The current cleaning device is composed of separate equipments that work together to complete the cleaning operation, which is very inconvenient to use and low in work efficiency

[0004] In addition, due to the high content of magnesium and calcium in ordinary tap water, such dissolved salts will remain on the surface of parts during engine thermal cleaning, which may cause the following hazards: (1) roughen the surface of the air intake and blades , which in turn can lead to an increase in exhaust temperature or even overheating, and a decrease in engine power

(2) Blocking the cooling holes of the combustion chamber or turbine guide vane, resulting in a decrease in the cooling efficiency of the uneven flow field, which can lead to local overheating and even cracks
