Diesel Tank Quality Inspection Guide
Essential steps to ensure your diesel tank with pump meets quality and safety standards
1Observe the Tank and Accessories Materials
- Check for corrosion-resistant and impact-resistant materials
- Ensure the tank surface is smooth and flat without scratches or dents
- Avoid products made of thin or easily deformed materials
- Inspect pump casing material for high-strength metal or durable engineering plastic
- Look for absence of burrs and cracks in all components
- Verify the product has a solid feel and moderate weight
- Request material specifications from manufacturer
- Confirm resistance to diesel corrosion and high-temperature resistance
2Test the Pump's Operating Performance
- Listen for low and even operating noise after starting
- Check for absence of harsh noises or irregular vibrations
- Observe oil supply speed under normal voltage and power
- Ensure oil supply is smooth and stable without interruptions
- Test the pump's start and stop function
- Confirm switch sensitivity and quick response
- Verify no delays or stuttering in operation
- Ensure core performance meets standards
3Check the Overall Sealing
- Focus on seals at tank joints and pump-pipeline connections
- Apply soapy water to joints and observe for bubbles
- Inject small amount of diesel and start pump to test for leaks
- Inspect sealing rubber ring on tank lid
- Ensure rubber ring is elastic without aging or cracking
- Verify tight fit when closed to prevent diesel volatilization
- Check prevention of foreign matter ingress
- Ensure sealing doesn't affect fuel safety and quality
4Inspect Safety Design
- Check for anti-static features like dedicated grounding terminal
- Look for anti-static components inside pump body
- Verify overload protection functionality
- Ensure pump automatically shuts down when blocked or overloaded
- Inspect electrical components if present
- Confirm wiring connectors are properly insulated
- Check wire sheathing is thick, durable and without exposed wires
- Ensure overall electrical operation safety
