Abstract
A decanter-type centrifugal separator equipped with a continuous lubricant supply device capable of preventing leakage of lubricating oil along supply pathways, and supplying and discharging lubricating oil. The continuous lubricant supply device has a lubricating oil supply channel formed inside a bowl hub, an annular introduction channel that introduces lubricating oil into the lubricating oil supply channel, a lubricating oil infusion channel formed inside a holder, and an oil collector installed on an outer surface of an outer shaft. The annular introduction channel has a first annular groove formed inside the holder such that the groove is occluded on the inside by the outer surface of the outer shaft. The oil collector can orbitally revolve in a predetermined direction inside the annular introduction channel, thereby moving lubricating oil radially inward in the annular introduction channel so as to flow into the lubricating oil supply channel.
