为了使广大使用单位进一步了解 CBG 油泵的使用与修理方法,特从以下几方面作简要介绍。一、结构原理该油泵采用高变位渐开线齿型,卸荷槽呈圆形,属于轴向固定间隙外啮合齿轮油泵。总体结构分为三片组合式,泵体和前、后泵盖,内有侧板,轴承、密封环、O 形圈等件。齿轮两端面与侧板之间有一定的轴向间隙,齿轮外圆与泵体内孔有一定的径向间隙。主动齿轮两端装有铜密封环,使其在油压作用
In order to make use of the unit to further understand the CBG pump repair and repair methods, especially from the following brief introduction. First, the structure of the principle of the variable displacement gear with involute tooth, unloading trough was round, belonging to the axial fixed gap external gear pump. The overall structure is divided into three combined type, the pump body and the front and rear pump cover, there are side plates, bearings, seals, O-rings and other pieces. There is a certain axial gap between the two end faces of the gear and the side plate, and the outer circle of the gear has a certain radial clearance with the bore of the pump body. The ends of the driving gear are fitted with copper sealing rings to make them work under hydraulic pressure
