Abstract


Application of Roots pump has a very wide range as a kind of rotary positive-displacement pump. With the increasing use on chemical industry, medicine, foodstuff and so on, the requirement of high efficiency, low resistance, naught pollution, stable quality of passing own pump, wide range of medium paste values etc. are greatly called. Linear Roots pump can not satisfy these requirements now. Helical Roots pump has great improvements on the face of stabilizing pressure pulse quality of passing cut sensitivity medium, reducing noises and vibration, avoiding vapor fret etc. Today, the powerful three-dimension function of drawing software at home and abroad and the development and progress of present intelligent machining methods have provided the precondition of the helical rotor s design and production of the pump. This thesis tries to do some research work on the face of Roots pump design and rotor parameter.the main contents:1. Researching the theory of Roots pump and designing a model. Try to achieve less volume, lighter weight, simpler structure and more reliable quality. As to the rotor shape design, because such type of research is undeveloped in our country, theory is still immature and information is inadequate, so these are the liabilities of this research. This is also the important content of this paper. Theorizing the rotor shape equation. Calculating the rational and veracious helical angles, connecting up the rotor curve sharply. Realizing thehigh efficiency, low resistance and nullity of interference. FinallyIIfinishing all the design of the LC-18/0. 6 helical three-lobe Roots pump.2. Finishing the parameterized three-dimension solid graph design of the involute-dowel gear arc Roots rotor with the programing language VBA embedded in AutoCAD2000 and programing driving methods. Establishing the foundation to improve the rotor shape parameter dramatically, realizing the Roots pump series design and production, sufficing the condition of the agile manufacturing technology.
