Abstract
PURPOSE: To utilize the stir-attraction of eddy current for maintaining sufficient suction capacity even though the suction height of a suction nozzle is increased.
CONSTITUTION: When a not-illustrated suction pump is started, suction objects 3 such as sediment at water bottom are sucket together with water through the open end 2 of a suction nozzle 1. At the time, the eddy current of suction fluid is formed due to the presence of a deflecting plate 4, and said suction objects 3 are stirred and raised by said eddy current and sucked efficiently. Further, negative pressure is generated at the center of said eddy current, the suction objects 3 therearound are aradually led to said center, i.e. just under said nozzle 1, raised and sucked into said nozzle 1. Therefore, sufficient suction efficiencies are ensured even though suction height H is increased. Thus, said suction pump is suited for suction work particularly at very uneven water bottom.
