Portable efficient suction inlet diffuser

Abstract

The invention belongs to the technical field of filters, and particularly relates to a portable efficient suction inlet diffuser which can solve the problems that sewage cannot be fully filtered from the peripheral outer wall of a filter element when the sewage is filtered due to the fact that the filter element is filled in the suction inlet diffuser, the filtering effect is easily affected, and the filtering efficiency is reduced. Impurities filtered by the filter element are gradually increased along with the increase of the service time, and the volume of the filter element is expanded, so that great resistance is generated between the filter element and the pipe fitting, and the filter element cannot be conveniently replaced and cleaned in the later period; and normal rotation of fan blades of the water pump is affected by the vortex effect of water on the inner wall of the pipeline in the process that filtered sewage is sucked by the water pump.

Description

technical field [0001] The invention belongs to the technical field of suction port diffusers, and in particular relates to a convenient high-efficiency suction port diffuser. Background technique [0002] The suction inlet diffuser is installed directly on the flange of the vertical pump inlet or inside the nozzle on the suction side connected to the upper end of the pump inlet. gender filter. [0003] There is a filter element inside the suction diffuser to filter the impurities in the sewage, and the filtered water flows into the suction end of the pump, and the connection between the suction diffuser and the pipeline can usually be changed by installing pipe fittings of different diameters; The filter element placed inside the current suction diffuser is usually directly filled inside the diffuser, resulting in the inability to fully filter the sewage from the outer walls of the filter element when filtering sewage, which will easily affect the filtering effect and redu...

Problems solved by technology

[0003] There is a filter element inside the suction diffuser to filter the impurities in the sewage, and the filtered water flows into the suction end of the pump, and the connection between the suction diffuser and the pipeline can usually be changed by installing pipe fittings of different diameters; The filter element placed inside the current suction diffuser is usually directly filled inside the diffuser, resulting in the inability to fully filter the sewage from the outer walls of the filter element when filtering sewage, which will easily affect the filtering effect and reduce the filtration efficiency; With the increase of time, the filtered sundries will gradually increase, and the volume of the filter element will expand, so that there will be great resistance between the filter element and the pipe fittings, making it impossible to replace and clean the filter element conveniently in the later stage; and the filtered sewage will be sucked by the water pump. During the process, the normal rotation of the fan blades of the pump will be affected by the vortex effect of the water on the inner wall of the pipe.
