4. Typical Applications

• Industrial Production: Used for wear resistance testing of components in mining, construction, and agricultural machinery (e.g., excavator teeth, bulldozer tracks, and blades) to extend equipment service life.
• Material R&D: Ideal for evaluating new materials like metal alloys, ceramics, coatings, and polymers, providing data support for material optimization and technological iteration.
• Quality Control: Acts as core equipment for batch sampling to ensure that components meet industry standards and reliability requirements before delivery.
• Scientific Research: Simulates various working conditions (dry/wet sand, different loads/speeds) to study abrasion mechanisms and assess surface treatments like carburizing and coating.

5. The Principle of RT-119:

This RT-119 abrasive wear testing machine delivers quartz sand via free fall from the metal sand outlet. The clockwise-rotating rubber wheel drives abrasive media such as quartz sand and gravel to wear surfaces of metallic and non-metallic materials, completing abrasive wear tests.
The rubber wheel supports adjustable working pressure, and key test parameters are configurable to simulate various practical operating conditions. The machine is suitable for laboratory wear resistance testing of materials used in mining, construction, transportation, and agricultural machinery. It also supports scientific research on material abrasive wear mechanisms.
An adjustable clamping device is fitted to extend the rubber wheel’s service life by allowing flexible fixture positioning. A built-in revolution counter automatically stops the machine once the preset wear revolutions are reached, ensuring precise test data.
The machine consists of a transmission system, specimen clamp, adjusting device, hardness testing device, speed control system, electrical control unit, base and sand trough.

6. Operational Guidelines & Maintenance Protocols

1. Safety & Emergency Protocols

• Electrical Safety: Always verify proper grounding before startup to prevent short circuits or electrical hazards.
• Personal Protection: Operators must wear protective gloves and safety goggles to prevent injuries from slurry splashes or contact with heated components.
• Emergency Stop: If abnormal vibration, overheating, or unusual noise occurs, shut down the machine immediately. Never force operation under faulty conditions.

2. Precision Parameter Control

• Accuracy Standards: Load, speed, and stroke must be strictly set according to testing standards. Ensure the load error is maintained within ±1%.
• Speed Calibration:
  • Dry Sand Test: Maintain a rubber wheel linear velocity of 140 ± 5m/min.
  • Wet Sand Test: Maintain a rubber wheel rotational speed of 245 ± 5r/min.
• Abrasive Management: Use abrasives that meet exact specifications. Never mix dry and wet abrasives, and strictly control the slurry concentration for wet sand testing.

3. Maintenance & Calibration Protocols

• Cleaning & Rust Prevention: Thoroughly clean the machine after each test. Apply anti-rust oil to unpainted metal surfaces. Increase maintenance frequency during humid/rainy seasons.
• System Lubrication: Regularly inspect the transmission system and lubricate guide rails and gears.
• Component Lifespan: Dress or replace the rubber wheel once the cumulative friction stroke reaches the specified threshold. Sensors and force measurement systems should be professionally calibrated every 1-2 years.

4. Standardized Testing Procedures

• Specimen Mounting: Ensure the specimen is securely fixed and maintains uniform contact pressure with the rubber wheel.
• Cooling Intervals (Dry Sand): For dry sand testing, allow at least 30 minutes between consecutive tests to ensure the rubber wheel returns to room temperature.
• Running-in Requirement: Use the same rubber wheel for both pre-grinding and the formal test. The wear scar must be a standard rectangular shape.
• Data Integrity: Record all test data in real-time to ensure results are accurate, reliable, and traceable.

7. FAQ (Strategic Trust Building)

• Q: Can this machine test non-metallic materials?
  • A: Yes. It is highly effective for testing plastics, ceramics, and composites, provided they fit the standard specimen dimensions.
• Q: How is wear measured?
