Dynamometer Safety: 5 Core Dimensions to Mitigate High-Risk Hazards

Dynamometers operate under high torque, speed, and temperature—safety directly impacts operator protection, equipment lifespan, and compliance. A comprehensive safety system spans 5 key dimensions, ensuring risk-free operation:

1. Design & Manufacturing (Fundamental Safety)

• High-strength alloy components (frame, coupling) are validated to withstand 1.5–2 times the rated load via FEA (Finite Element Analysis).
• Dual overload protection: mechanical (overload clutches) + electrical (current relays) for 1.2-1.5x rated load.
• Rotating components: enclosed guards (tempered glass viewports); high-temperature parts: thermal insulation layers to prevent accidental injury.

2. Installation & Commissioning (Hazard Prevention)

• Rigid fixation on concrete/steel bases (≥2x equipment weight capacity) with anchor bolts.
• Independent grounding (≤4Ω) + separated power/control wiring to avoid electric hazards.
• Validate emergency stop (≤0.5s response) and sensor accuracy (≤±1% error) during commissioning.

3. Operation & Maintenance (Dynamic Safety)

• Trained operators only—no overloading or skipped preheating.
• Daily checks: coupling wear (≤0.2mm), coolant temperature (≤50℃), lubrication.
• Weekly electrical inspections + monthly sensor calibration (≤±2% deviation).
• Multiple emergency stops (local/console/remote) with manual reset.

4. Environment Control (Safety Scenario)

• Operating conditions: 0-40℃, ≤85%RH (no condensation); dust/corrosion-free area.
• ≥1.5m safety clearance + warning signs; fire extinguishers for electrical hazards.

5. Compliance & Certification

• Meet GB/T 18297, ISO 13849, CE standards; annual third-party safety audits.

Summary

Dynamometer safety relies on "design integrity + standard installation + strict operation + regular maintenance + compliant environment." A full-chain approach mitigates risks effectively!
