补油参数对离子液体氢气压缩机的性能影响
Effects of the oil recharging parameters on the performance of the ionic liquid compressor
摘要
Abstract
To study the thermal performance of the ionic liquid compressor,this paper established an energy analysis model,based on which the energy conversion mechanisms were investigated and the energy loss was categorized into three parts:the hydraulic loss,the oil cylinder loss and the gas cylinder loss.Based on the sources of where the losses took place,the energy loss was further subdivided into overflow loss,recharge loss,pipe loss,buffer loss,friction loss,suction loss,discharge loss and heat transfer energy-saving.A simulation model for the single-stage ionic liquid compressor was developed and validated experimentally.The results indicated that the overflow loss,recharge loss and buffer loss were the most significant contributors.The pressure and flow rate of the recharge pump primarily affected the adiabatic efficiency by changing these three dominating losses.Specifically,the increase in the recharge pressure from 1 MPa to 6 MPa led to a 20.6%growth in the overflow loss and a 10.57%reduction in the adiabatic efficiency,while the increase in the flow rate of the recharge pump from 20 L/min to 120 L/min resulted in a 35.8%growth in the recharge loss and a 21.84%reduction in the adiabatic efficiency.The research can provide theoretical basis for the efficient design and operation of ionic liquid hydrogen compressors.关键词
