の満水検知装置。 This is a full water detection device for a pump that requires priming at startup, and forms an air chamber independent from the intake path on the intake side of the vacuum pump of the main pump casing when the vacuum pump takes air; An electrode is attached to the upper wall through an insulator, and the side wall of the air chamber is used as a ground electrode to detect full water when the water level reaches the electrode.The air chamber is connected to the main pump discharge pressure. A full water detection device for a pump, characterized in that compressed air remains even during operation to prevent the water surface from reaching at least an insulator.
