三螺杆泵衬套的最小工作长度分析
Analysis of the minimum working length of case in three screw pump
摘要
Abstract
One of the conditions for sealing in three screw pump with cycloid profiles was that the length of case must not be less than the minimum working length, so that the suction and discharge chamber could be separated strictly. This study deduced the conditions from the equation of meshing that the length of case must meet, and gave the three dimensional graph of different sealing chamber. This study provided the theoretical basis for correct determination of case length, analysis of the instantaneous flow rate, pressure distribution and volumetric efficiency in three screw pump.关键词
