问:有经验的驾驶员,在液压泵刚接合后,为什么先提升一下农具? 答:CB系列泵按润滑形式的不同分高压供油和低压供油两种.现在采用比较普遍的为高压供油润滑. 高压供油润滑,在轴套内孔非负荷区有纵向油槽,内端面除有集油环槽外,尚开有八字形供油槽.油泵工作时,供油槽与压油腔齿槽可断续相通,通时便将高压油导入集油环槽,再沿纵向油槽进入轴套内孔.油液润滑后,通过下座孔回油槽或泵盖回油斜孔仍回到吸油腔.高压供油润滑的特点是:压油腔齿槽内的
Q: Experienced drivers, just after the hydraulic pump is engaged, why raise the farm tools? A: CB series pumps by lubrication in different forms of sub-high-pressure fuel supply and low pressure two. Now more commonly used for high-pressure supply Oil lubrication. High-pressure oil lubrication, non-load area in the sleeve bore longitudinal groove, the inner end except for the oil ring groove, is still open eight-shaped oil groove. Oil pump work, the fuel tank and the pressure tank alveolar Intermittent communication, when it will be high-pressure oil into the oil collection ring groove, and then along the vertical groove into the sleeve bore. After the oil lubrication, through the lower hole back to the oil tank or pump cover back to the inclined hole is still back to the oil absorption chamber High pressure oil lubrication is characterized by: the pressure tank cavity
