活塞式压缩机是由电能转换为气体压力能的能量转换设备。它广泛用于空压、空调、制冷等各个行业。在开展企业能量平衡工作中,需测算出压缩机组效率、管网泄漏率、系统电能利用率,并对其测算结果进行分析,找出薄弱环节,采取措施,降低能耗。实际数据表明,活塞式压缩机系统能量损失大,耗电多,但节能潜力也大。如何进行该类系统能量平衡,找出提高其电能利用率的途径,应引起足够的重视。 Piston compressors are energy conversion devices that convert electrical energy to gas pressure energy. It is widely used in air pressure, air conditioning, refrigeration and other industries. In carrying out enterprise energy balance, it is necessary to calculate the compressor unit efficiency, pipe network leakage rate and system power utilization rate, and analyze the measurement results to identify the weak links and take measures to reduce energy consumption. The actual data show that the piston compressor system energy loss, power consumption, but energy-saving potential is also large. How to balance the energy of such systems and find out ways to improve the utilization rate of them should pay enough attention.
