Abstract

PURPOSE:To improve durability of a machine for handling work fluid having a high content of water, by lubricating the sections of roller bearings with raw liquid of work fluid having a high content of water or the like, and sealing the bearing sections by use of proper sealing means. CONSTITUTION:Roller bearings 3, 4 are lubricated by feeding raw liquid of work fluid having a high content of water (HWBF) or a highly dense fluid obtained by admixing a small amount of water to the raw liquid from a port 22, and the portions of the bearings 3, 4 are sealed by sealing means 5, 6. With such an arrangement, if leakage of liquid into a casing 17 is caused due to wear of the sealing means 5, separation of emulsion from the HWBF is never caused since the liquid has naturally the properties of the raw liquid of HWBF.
