Core Advantages
Nondestructive Testing: Avoids secondary damage caused by equipment disassembly and reduces maintenance costs.
Efficiency: Combining real-time imaging with data analysis quickly locates defect size.
Intelligence: AI algorithms automatically identify defects, improving inspection accuracy.
Classic Case Studies
Case 1: An automobile manufacturer inspected an engine block and discovered a 0.5mm crack, avoiding a recall.
Case 2: During aircraft engine maintenance, a micron-level crack in a turbine blade was detected, enabling preemptive component replacement to prevent failure.
Case 3: During a petrochemical pipeline inspection, a 200-meter pipeline scan was completed in 4 hours, identifying three corrosion points and preventing potential leaks.
Requirements Analysis
Identify the inspection target (e.g., engine, pipeline), environment (high temperature, corrosive media), and accuracy requirements (micron-level defects).
Equipment Selection
Select a rigid or flexible endoscope based on your needs, focusing on the following parameters:
Diameter: Ultra-fine design (e.g., φ1.7mm or smaller).
Viewing angle: Wide-angle or directional.
Light source: LED or rear-mounted illumination, IP67 waterproof rating.
Operation Training
Technicians must master probe control, image analysis, and measurement functions (e.g., ruler, negative display).
Process Development
Standardized inspection steps:
Pre-treatment: Clean the inspection port.
Probe Insertion: Insert slowly to avoid collisions.
Image Acquisition: Capture images from multiple angles and mark defect locations.
Report Generation: Automatically generate inspection reports containing defect size and location.
Maintenance and Calibration
Regularly check probe wear and light source brightness to ensure equipment is in optimal condition.
Intelligent Upgrades: Integration with 5G communications enables remote, real-time inspection and data analysis.
Material Innovation: High-temperature and corrosion-resistant probes adapt to extreme environments.
AI Deep Integration: Automatic defect classification and predictive maintenance improve inspection efficiency and accuracy.
By deeply integrating its technical characteristics with the needs of the machinery industry, industrial endoscopes have become a key tool in nondestructive testing, significantly improving inspection efficiency and equipment safety, and driving the manufacturing industry towards intelligent and refined processes.
