1 现行阶梯结构叶片的工作情况 双作用叶片泵工作压力的提高主要受到定子内表面与叶片之间的磨损限制,由于叶片根部通过油腔,当叶片处于吸油区时,叶片顶部受到吸油腔的压力、叶片根部受到压油腔的压力,这样叶片顶部和根部之间形成了很大的压力差,使叶片作用在定子内表面磨损严重,因此,一般工作压力不超过7MPa,为了增大工作压力,把叶片加工成
1 the current work of the ladder structure of the blade double-acting vane pump working pressure increase is mainly due to the inner surface of the stator and the blade between the wear and tear restrictions, as the root of the blade through the oil chamber, when the blade in the oil absorption zone, the blade top by the suction chamber pressure , The blade root pressure by the pressure chamber, so that the top of the blade and the root between the formation of a great pressure difference, so that the role of the blade in the stator surface wear serious, therefore, the general working pressure does not exceed 7MPa, in order to increase the working pressure, The leaves into processed
