Liquid Feeding Lobe Pump Design And Numerical Simulation

Fed liquid has been obtained in small farming households of all ages, they to pigs fed food including liquid and semi-liquid feed. In recent years, feed liquid in the production, save, transport technology made certain development, there are large farms began to pigs to implement modern automation liquid feeding. Obviously, comprehensive advantages of liquid feeding began is more and more people pay attention to. In order to realize the liquid feeding, we need a dynamic element.The information that the roots pump or cam rotor pump of this type of volume type pump to meet the requirements. On the one hand, this type of pump can produce strong self suction in the inlet, capable of conveying viscous fluid material and material containing small particles. On the other hand, the pump has the advantages of small size, strong power, low speed, low noise, less pollution, easy to clean, will not damage their physical and chemical properties of the pump material, fully meet the ecological welfare needs. Breeding facilities and are often familiar with centrifugal pump, gear pump does not have these features. In addition, roots the pump is a proportional rotary displacement pump by controlling the rotational speed of the rotor, to control the transmission flow, therefore, can be used as a metering pump.This paper derives the roots blower rotor curve equation and the use of MATLAB programming to draw the rotor profile curve, Excel extraction, set up a two-dimensional coordinate conversion, using SolidWorks 3D model. To complete the design of feeding pump for roots, the 3D assembly in SolidWorks. After simulation, the two rotor movement is verified. Finally, a simplified fluid pump cavity model, using Gambit triangular mesh. The mesh division of quality inspection, the custom of fluid materials into Fluent for fluid simulation. Through dynamic grid simulation, the velocity vector of each fluid in the pump cavity moment, pressure nephogram. Establishment of digitization, visualization of fluid model for the pump for liquid feeding and provide a theoretical basis and performance prediction.
