METHOD AND DEVICE FOR DETECTING LEAKAGE OF OIL AIR FROM BEARING BOX LUBRICATING DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To surely detect the leakage of oil air from an oil air supply pipe and/or a bearing box in a bearing box lubricating device for supplying oil air into the bearing box. SOLUTION: A check valve 15 for restraining the flow of oil air from the downstream side to the upstream side is installed in the bearing box lubricating device on the downstream side of the oil air supply pipe 7. A pressure detection means 16 for detecting the pressure in the oil air supply pipe 7 is installed on the upstream side of the check valve 15. A shaft seal mechanism 13 is installed in the bearing box 4 to maintain the inside of the bearing box 4 at a predetermined pressure. When the supply of the oil air is stopped, the change of the pressure detected by a pressure detection means 16 is checked to determine whether or not there is oil air leakage from the oil air supply pipe 7 and/or the bearing box 4.
