Claims (1)
タ側に洩れないようにオイルシールにてシールし
ている真空ポンプにおいて、前記オイルシール部
の空間に臨ませて潤滑油の温度を検知する温度セ
ンサを設け、該温度センサからの出力がある一定
値に達したとき真空ポンプを停止する制御部を設
けたことを特徴とする真空ポンプ。 In a vacuum pump that is sealed with an oil seal to prevent the oil lubricating the bearings of a pair of rotors from leaking to the rotor side, the temperature of the lubricating oil is detected by looking into the space of the oil seals. A vacuum pump comprising a sensor and a control section that stops the vacuum pump when the output from the temperature sensor reaches a certain value.
