分析了气动执行器的能耗特点,结合空气消耗量和比能量概念,提出了一种气动执行器的能耗计算方法.为解决公用气动设备的购置成本划分问题,提出了一种用气设备成本均分法.结合生命周期成本的概念,建立了气动执行器基于用户的全生命周期成本模型(LCCBOU,Life-Cycle Costing Based On Users),进行了实例验证.该模型不仅适用于气动执行器的全生命周期成本分析,也适用于其它用气设备的成本分析.结果表明:用气设备成本均分法实现了气动系统成本的合理划分;气动执行器的LCCBOU模型通过了实例验证,并发现通过空压机的实时监控和气动系统的泄漏测量,LCCBOU模型结果能够做到更精确.
Based on the analysis of the characteristics of energy consumption of pneumatic actuators, a method for calculating the energy consumption of pneumatic actuators was proposed based on the concepts of air consumption and specific energy. To solve the problem of the purchase cost of pneumatic equipment, A method based on Life Cycle Costing Based On Users (LCCBOU, Life-Cycle Costing Based On Users) was established, which is based on the concept of life cycle cost.The model is validated not only for pneumatic actuator The life cycle cost analysis of the pneumatic system is also applicable to the cost analysis of other gas equipment.The results show that the gas system cost sharing method is used to realize the reasonable division of the pneumatic system cost.The LCCBOU model of the pneumatic actuator is verified by examples and found Through the real-time monitoring of air compressor and pneumatic system leakage measurement, LCCBOU model results can be more accurate.
