液压泵测试数据集

采集液压泵在多种工况下的关键性能参数，并进行严格关联：核心采集数据：身份数据：泵的唯一编号、型号、生产批次。工况数据：测试转速、输出压力、油液温度、油液粘度。性能数据：流量、容积效率、总效率、输入扭矩/功率、出口压力脉动、壳体振动、噪声值。耐久数据：在耐久测试中，上述性能数据随时间/循环次数的变化曲线。关键处理规则：性能计算：基于直接测量值（流量、压力、扭矩）计算容积效率和总效率，这是衡量泵性能的核心指标。数据对齐：将所有性能数据与精确的工况参数（如某一特定压力下的效率）和时间戳严格对应。合格判定：将测试结果与设计规格书中的标准值进行比对，自动判定产品合格/不合格，并对不合格品标注具体原因，如“额定压力下流量不达标”、“容积效率衰减过快”、“异响” 等。

We collected key performance parameters of hydraulic pumps under various operating conditions and established strict correlations among them.

Core collected data:
1. Identity data: Unique serial number, model, and production batch of the pump.
2. Operating condition data: Test rotational speed, output pressure, oil temperature, and oil viscosity.
3. Performance data: Flow rate, volumetric efficiency, total efficiency, input torque/power, outlet pressure pulsation, housing vibration, and noise level.
4. Durability data: Curves showing changes of the above-mentioned performance parameters over time or number of cycles during durability tests.

Key processing rules:
1. Performance calculation: Volumetric efficiency and total efficiency, which are core indicators for evaluating pump performance, are calculated based on directly measured values including flow rate, pressure, and torque.
2. Data alignment: All performance data are strictly matched with precise operating condition parameters (e.g., efficiency under a specific pressure) and timestamps.
3. Qualification determination: Compare test results with standard values specified in the design specification to automatically judge whether the product is qualified or not, and mark specific reasons for unqualified products, such as "Flow rate does not meet the standard under rated pressure", "Volumetric efficiency decays too fast", "Abnormal noise", etc.
