一种新型液体输送泵的输送性能模拟
Performance Simulation on a New Type of Liquid Pump
摘要
Abstract
Electricity-driven liquid pumps characterize high power consumption.A new type of liquid delivery pump driven by low grade waste heat proposed by Institute of Refrigeration and Cryogenics of Zhejiang University has the potential of energy saving.CFD method is utilized to analyze the flux characteristics of the new liquid pump to prove the feasibility of the new pump in structure.In addition,transport quality influenced by different rotor material as well as different channel and the change of conveying velocity is studied as well.The result shows that the docking lag (to overcome the surface tension) time of hydrophilic material is shorter and that the liquid in channel exit four process (overcome surface tension;speed up;deceleration;overcome surface tension) and that compared to round channel,the flux scale of sector is more efficient.The simulation has guiding significance for material selection,channel form selection and fellow up experiment of the new pump.关键词
