摘要
为了掌握简易升降机的能耗和能源利用效率情况,对简易升降机不同工况下的能量传递规律进行了研究,针对实际情况制定了简易升降机能效对比测试的测试方案,采用了供给能、有效能标称值和能效标称值三条定义,确定了以能效标称值作为评价简易升降机能源消耗水平的指标,实际测试过程中采用三相电能质量分析仪对两台参数基本一致的简易升降机进行了能效测试,并对不同工况下各品种简易升降机的供给能、有效能标称值、能效标称值、有功功率以及上述测量值的理论计算值进行了对比分析。测试结果和分析表明,强制式简易升降机在下降工况存在能量反馈环节,总体上曳引式简易升降机比强制式简易升降机节能,这也为简易升降机能耗的评价提供了可靠的实测数据。
In order to obtain the energy consumption and efficiency data of simple lifts, energy transfer was studied under different working conditions. Comparative testing scheme of energy efficiency was established according to the actual situation. Among energy supply, effective nominal value and the nominal value of energy efficiency, the nominal value of energy efficiency was shose as the index to evaluate the simple lift energy consumption level. Three-phase power quality analyzer was adopted to test the energy efficiency of two different type simple lifts with same parameters. The measured values of energy supply, available energy, energy efficiency and active power were comparative analyzed with the theoretical values under different working conditions. Finally, test results and analysis show that since there is an energy feedback loop during the falling process for the forced type simple lift, the overall traction type simple lift is more energy-saving. Also, the test results provide the foundation for energy consumption of simple lifts.
