    • A scroll compressor oil pumping system has a concentric axial bore located in the driveshaft of the compressor which serves as the primary oil pump. The driveshaft is journaled in a lower bearing housing and is located within the oil sump of the compressor. An inlet housing is attached to the lower bearing housing and creates a stepped flow path for the oil between the sump and the oil pump. The inlet housing may also be equipped with a plurality of air foil shaped vanes to impede the formation of a bottom vortex. The stepped flow path causes an annular vortex to form which operates to separate the contaminants from the lubricating oil. In order to assist in the formation of the annular vortex, the driveshaft can include an impeller. The contaminants are channelled into a holding chamber formed by the lower bearing housing and the inlet housing. A plurality of funnel shaped orifices guide the contaminants into the chamber and operate to resist blow out of the debris during liquid flashing conditions. A magnet can be included within the holding chamber to attract the metallic contaminants if desired.
    • 涡旋压缩机油泵系统具有位于压缩机的驱动轴中的同心轴向孔,其用作主油泵。 驱动轴位于下轴承座中,位于压缩机的油底壳内。 入口壳体连接到下轴承壳体,并为油槽和油泵之间的油产生阶梯式流路。 入口壳体还可以配备有多个气翼形叶片以阻止底部涡流的形成。 阶梯式流动路径形成环形涡流,其操作以将污染物与润滑油分离。 为了有助于形成环形涡流,驱动轴可以包括叶轮。 污染物被引导到由下轴承壳体和入口壳体形成的保持室中。 多个漏斗形孔将污染物引导到室中并且在液体闪烁状态期间操作以抵抗碎屑的吹出。 如果需要,磁体可以包含在保持室内以吸引金属污染物。
