Title:
FULL-WATER DETECTOR AND PUMP WITH FULL-WATER DETECTOR
Document Type and Number:
Japanese Patent JP2016017841
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a full-water detector capable of preventing full-water from detecting with air remaining in a pump casing and a suction pipe and preventing suction of the residual air from being disabled, and capable of re-suctioning by a vacuum pump even when water in the pump casing drains.SOLUTION: The full-water detector is provided with: a housing 11 that has an inflow port for air and water at a bottom part and a suction port 11a at an upper part, the housing 11 being disposed in such a manner that a longitudinal direction is vertical; a float 15 that is provided in the housing 11 so as to be vertically movable; a sitting part that is a part provided at the bottom part of the housing 11 and on which the float 15 sits by lowering by its weight, the sitting part having a flow path that allows the water to flow into the housing 11 when being sit by the float 15; a stopper that is provided in the housing 11 and defines an upper limit position of the float 15 pushed up by the water flowing from the inflow port; and a detection part that detects, due to a water-level rising in the housing 11, that the water is filled.SELECTED DRAWING: Figure 2
