VACUUM STATION AND VACUUM PUMP WATER SEALING METHOD

SUZUKI AKIRA / IKEDA KEISUKE

To provide a vacuum station that can suppress deterioration of sealed water in a vacuum pump.SOLUTION: A vacuum station comprises: a tank that stores a liquid entrained with gas; a water-sealing type vacuum pump that sucks the gas from the tank; a sealed water tank that separates sealed water used in the vacuum pump and the gas discharged from the vacuum pump and stores the separated sealed water; a sealed water pump that supplies the sealed water from the sealed water tank to the vacuum pump; a fresh water supply device that supplies fresh water (tap water) neutralizing solution to the sealed water tank; a measuring device that measures pH of the sealed water stored in the sealed water tank; and a control unit. The control unit controls supply/stop of the fresh water (tap water) from the fresh water supply device based on a measured value of pH of the sealed water.SELECTED DRAWING: Figure 1

【課題】真空ポンプの封水の劣化を抑制する【解決手段】真空ステーションは、気体と同伴搬送された液体を貯めるタンクと、タンクから前記気体を吸引する水封式の真空ポンプと、真空ポンプに用いられた封水と真空ポンプから吐出された気体とを分離するとともに、分離された封水を貯蔵する封水タンクと、封水タンクから真空ポンプに封水を供給する封水ポンプと、封水タンクに清水（水道水）和液を供給する清水供給装置と、封水タンクに貯蔵された封水のｐＨを計測する測定器と、制御部を備える。制御部は、封水のｐＨの測定値に基づいて清水供給装置からの清水（水道水）の供給／停止を制御する。【選択図】図１
