Title:
DETECTING METHOD OF ABNORMALITY IN SUPPLY OF LUBRICATING OIL
Document Type and Number:
Japanese Patent JPS61192960
Kind Code:
A
Abstract:
PURPOSE:To detect an abnormal pressure, by regulating the pressure in feed pipes through throttle valves, provided between the feed pipes and a supply air pipe, and through throttle valves in the ends of the feed pipes while the pressure in lubricating oil pipe lines through throttle valves provided between the feed pipes and the pipe lines. CONSTITUTION:The pressure in feed pipes 6 is set higher than the atmospheric pressure and lower than the pressure in a supply air pipe 1 by the first throttle valves 12, provided in connection parts between the feed pipes 6 and the supply air pipe 1, and the third throttle valves 11 in the ends of the feed pipes 6. While the pressure in pipe lines 14 is equally set to the pressure in supply pipe lines 7 by the second throttle valves 13 provided in connection parts between the feed pipes 6 and the pipe lines 14. And abnormality of the pressure, when it deviates from a preset value, is detected by pressure detecting means 15. Consequently, the abnormality in supply of lubricating oil and air to a bearing can be correctly detected.
