<p>PURPOSE:To facilitate the control of a water level by a structure that a long pipe is supported on the side of the pump movably in the vertical direction and starting float switch is mounted at an appropriate position in the long pipe in such a manner that it can be suspended from the long pipe as well as float on the water surface. CONSTITUTION:The long pipe 4 is supported on the side of the pump 1 through a pair of linkages 8 and 9 movably in the vertical direction, and at an appropriate position in the long pipe, there is mounted the starting float switch 5 in such a manner that it can be suspended from the long pipe as well float on the water surface. With such a construction, the starting float switch 5 can be changed in the operation position easily by the pushing down or lifting up of the long pipe 4. Thus, the water level can be easily controlled.</p> |
