PURPOSE:To eliminate need for a separate wafer system for lubrication purpose so as to clear any limitation for establishing a hydraulic machine, by feeding pressure water staying in the hydraulic iron pipe or the casing of the hydraulic machine into a water lubricated bearing through a foreign matters removing apparatus. CONSTITUTION:Pressure water in a hydraulic iron pipe or a casing 19 is led to an earth and sand removing apparatus 20, and thus cleared water is fed into the feed water chamber 9 of a water lubricant bearing 4, and the necessary performance of the bearing is maintained by taking the water in the bearing through a feed water port 11. The diameter of each and sand in the lubricating water cleared by the earth and sand removing apparatus 20 can be made about 60mu or less, and it does not matter to practial use. |
