Cleaning Solution for Aero-Engine Blades After Grinding
In the field of aviation manufacturing, aero-engine blades are core components of the engine, and the cleaning quality after grinding directly affects the engine’s operational efficiency and safety performance. The Shanghai Yingke Automation Rotational Spray Cleaning Machine is custom-designed for the cleaning needs of aero-engine blades, serving as a key equipment to solve the cleaning challenges of blades after grinding.
After the grinding process of aero-engine blades, a large amount of stubborn contaminants remain on their surfaces, including metal debris generated during grinding (with particle sizes as fine as micrometers), oil residues from grinding fluids, and dust attached during processing. If these contaminants are not thoroughly removed, they will pose serious risks in subsequent blade assembly and engine operation—such as accelerating blade wear, affecting airflow stability, or even causing malfunctions. Meanwhile, aero-engine blades are mostly made of high-strength, high-precision materials such as superalloys and titanium alloys, with complex structures (including multiple parts like the blade body, tenon, platform, and damping platform). The cleaning process requires both thorough removal of contaminants and prevention of scratches, corrosion, or deformation on the blade surface, placing extremely strict requirements on cleaning equipment.
The core working principle of the rotational spray cleaning machine is to achieve precise cleaning through multi-dimensional synergistic effects.
The equipment adopts a programmable rotational spray system. The spray pipe in the cleaning chamber features a C-shaped structure, and the workpiece is equipped with a 360° self-rotation function, forming a three-dimensional cross spray trajectory. This ensures that every tiny part of the blade (including hard-to-reach areas such as the back grooves and tenon tooth gaps that traditional cleaning methods struggle to cover) is fully exposed to the cleaning fluid. Its spray pressure is controlled with a closed-loop precision system, which can be accurately set according to the blade material (e.g., 0.5-0.8MPa for titanium alloy blades and 0.8-1.6MPa adjustable for superalloy blades) and contaminant type. This not only strips stubborn debris through high-pressure impact but also avoids blade damage caused by excessive pressure.
The equipment boasts several core advantages:
1. Industry-leading cleaning precision
Equipped with a high-precision filtration system, the cleaning fluid undergoes three-stage filtration (primary filtration accuracy of 50μm, fine filtration accuracy of 5μm), effectively intercepting grinding debris and impurities to prevent secondary contamination. Meanwhile, targeting the complex structure of aero-engine blades, the spray holes adopt an angle-adjustable nozzle technology to achieve full-coverage adjustment, ensuring the sprayed cleaning fluid forms focused water streams that precisely impact contaminant attachment points.
2. Both efficient cleaning and environmental friendliness
It adopts a multi-stage cleaning process (pre-cleaning - main cleaning - rinsing - drying), with independent parameter settings for each stage. The main cleaning stage uses aviation-specific environmentally friendly cleaning agents (compliant with SAE AS4059 standards), which combine strong decontamination capabilities with low corrosiveness. Cooperated with a temperature control system of 80-95℃, it can quickly dissolve oil stains. The drying stage combines hot air circulation and vacuum drying to ensure no residual water stains on the blade surface, meeting the strict requirements of subsequent coating or assembly.
3. Intelligence and stability guarantee
The equipment uses a Siemens PLC control system, which can store multiple blade cleaning programs. Operators only need to select the corresponding model to automatically execute the cleaning process, reducing human errors. It is also equipped with multiple sensors (including pressure sensors, temperature sensors, liquid level sensors, etc.) to monitor cleaning parameters in real-time. In case of abnormalities, it immediately triggers an alarm and automatically adjusts, ensuring the stability and consistency of the cleaning process.
4. Compliance with high aerospace industry standards
The main frame of the equipment is integrally welded with 304 stainless steel, achieving aviation-grade corrosion resistance. The inner wall of the cleaning chamber has no hygiene dead corners, facilitating daily cleaning and maintenance, and providing reliable quality assurance for aero-engine blade cleaning.
In addition, the rotational spray cleaning machine features flexible production adaptability. It can quickly replace customized fixtures according to the size and structure of different types of aero-engine blades, enabling efficient switching between multi-variety, small-batch production. The cleaning efficiency is 5-8 times higher than traditional manual cleaning, and the cleaning qualification rate remains stable above 99.9%, significantly reducing the subsequent processing costs and quality risks of aero-engine blades.
With its professional design tailored to the cleaning needs of aero-engine blades after grinding, and its outstanding performance in precision, efficiency, intelligence, and compliance, the Shanghai Yingke Automation Rotational Spray Cleaning Machine has become a core equipment for blade cleaning in the aviation manufacturing field, providing solid support for the high performance and high reliability of aero-engines.
