Inspection Protocol for Part Assessment

Ensuring each mechanical component functions flawlessly is crucial. Our rigorous inspection protocol is designed to detect potential issues early. Below are the guidelines:

Visual Inspection Guidelines

• Before beginning, ensure all parts are thoroughly cleaned.
• Inspect for visible damages such as cracks, pitting, corrosion, scoring, and ridging.
• Identifying the source of failures can guide preventive actions and provide practical advice for customers to mitigate future issues.

Note: Visual checks may miss subtle or hidden damages; additional testing might be necessary.

Advanced Inspection Methods

• Water-pressure or air-pressure tests can be employed for detecting leaks or weaknesses.
• Cold checks or magnetic damage tests are recommended for thorough analysis.

Specific Defects and Solutions

Crack Detection and Management

• If cracks are visible, consider replacing the part.
• Replace parts if crack length or depth surpasses one-third of the part’s thickness.
• Internal cracks warrant component replacement.

Pitting Examination and Remedies

Pitting from Cavitation

• Cavitation often coexists with chemical corrosion. Post rust or scale removal, evaluate pitting depth meticulously.
• If pitting is irreparable within tolerable limits, part replacement is necessary.
• For minor pitting, resurface after rust and scale removal.

Pitting from Surface Wear

• Replace ball bearings if pitting is present.
• Parts with over one-third pitted contact surface should be replaced.
• Minor pitting warrants resurfacing of the component.

Conclusion

Proper maintenance and timely inspections are key to long-term functionality and safety of mechanical systems. Adhering to these guidelines will ensure maximum efficiency and longevity.
