高精密螺杆泵重叠网格涂胶性能分析
High Precision Screw Pump Overset Mesh Gluing Performance Analysis
摘要
Abstract
The sealing process with adhesive coating has always been an important part of aircraft assembly.However,currently,this work is usually performed manually.To address the disadvantages of manual adhesive coating,research has been conducted on the adhesive performance of automated coating using screw pumps.Considering the high precision control requirements of the coating process,boundary conditions are established based on the kinematic characteristics.The overlapping mesh technique of Fluent software is used to simulate the flow field of the screw pump,studying the influence of rotation speed on the internal flow velocity and outlet flow rate of the pump.The relationship between the screw speed and the flow rate and flow fluctuation in the tube is obtained,and the optimal rotor speed range is 20~80 r/min.By comparing with traditional moving mesh,it is concluded that the overlapping mesh technique greatly improves the accuracy and speed of the simulation.An experimental platform is built to verify the authenticity of the simulation,providing a theoretical basis for the operational parameters of screw pumps in automated adhesive sealing in the future.关键词
