PIPE ABNORMALITY DETECTION METHOD AND PIPE ABNORMALITY DETECTION DEVICE FOR OIL AIR LUBRICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a pipe abnormality detection method for an oil air lubrication system, enabling a detection of abnormality of an oil air pipe with a simple configuration even when supplying oil air to a plurality of lubrication points, even during oil air lubrication system operation.;SOLUTION: In the oil air lubrication system 1 wherein the oil air is generated by mixing lubricating oil and compressed air and wherein the oil air is carried to the lubrication points (bearing boxes B1-B10) along inner walls of oil air pipes by a flow of the compressed air, a flow rate and pressure of the compressed air are measured, and a value of the pressure to the flow rate is compared with a previously measured value in a normal time to detect presence/absence of leakage or closing of the oil air pipes 11, 12, 21-30.;COPYRIGHT: (C)2012,JPO&INPIT
