ETENWOLF S0 Portable Bike Pump Temperature Rise Test Report (185 Scans, Dual-Unit)

Key Findings

The ETENWOLF S0 portable bike pump completed a full 185-scan temperature-rise logging session, with both test units reaching thermal near-equilibrium; peak measured temperatures of 82.31 °C (S0-9# cylinder) and 82.25 °C (S0-2# nozzle connection) were recorded at the end of the run, while ambient laboratory temperature remained stable between approximately 26.1 °C and 26.8 °C throughout the entire test.

• Test type: Temperature-rise (温升) environmental test
• Product: ETENWOLF S0 Portable Bike Pump
• Units under test: S0-2# and S0-9# (two samples)
• Data logger: Keysight DAQ970A, S/N MY58035717
• Total scans: 185 (scan interval ≈ 5 seconds)
• Ambient temperature range: 26.18 °C – 26.78 °C
• Peak temperature – S0-2# nozzle connection: 82.25 °C (scan 183)
• Peak temperature – S0-9# cylinder: 82.30 °C (scan 184)
• Monitored points per unit: battery, cylinder, nozzle connection, hose tail, hose head (5 channels each)
• Thermal stabilisation observed: both units approached steady state after approximately scan 130

Test Overview

Test Equipment & Setup

Test Procedure

1. Pre-test preparation: Install the DAQ970A data acquisition system and connect thermocouple probes to all five measurement points on each sample unit (battery body, cylinder, nozzle connection, hose tail, hose head) plus one ambient reference probe. Verify VISA address and firmware version. Allow equipment to warm up and confirm ambient stability.
2. Initial baseline scan: Record scan 1 with the pump at rest to establish baseline temperatures across all channels (all channels expected near ambient ≈ 26–27 °C).
3. Pump activation: Start the S0 pump units and begin continuous inflation operation at rated conditions.
4. Continuous data logging: The DAQ970A automatically records all 11 channels at approximately 5-second intervals. Do not interrupt operation. Monitor for any anomalies.
5. Thermal run: Continue logging until temperature readings plateau and indicate thermal steady-state (target minimum 180 scans or visible stabilisation of all channels).
6. Post-test stop: After scan 185, stop pump operation. The DAQ970A logs the stop event (“数据记录已停止” – data logging stopped). Record final readings.
7. Peak temperature extraction: The system automatically extracts the maximum temperature recorded for each channel across the entire run (reported in the “最高温度” / Maximum Temperature row).
8. Acceptance criteria: All monitored surface temperatures should remain within safe operational limits throughout continuous operation. Thermal plateau must be demonstrated. No thermal runaway or uncontrolled temperature rise is acceptable.
