Shaft type pump device with annular water inlet groove

Abstract

The invention discloses a shaft type pump device with an annular water inlet groove, and belongs to the technical field of hydraulic engineering. The shaft type pump device comprises a shaft, a pump section, a horn pipe, a water outlet pipe and a water inlet pipe, and is characterized in that a water distributing vessel is arranged and located above guide blades, the bottom of the inner wall of the water distributing vessel is flush with the bottom of the inner wall of the water inlet pipe, the top of the water distributing vessel is flush with the top of the inner wall of the water inlet pipe, the clear weight is equal to the diameter of the water inlet pipe, the water distributing vessel is directly connected with the water inlet pipe, and water flows into the water distributing vessel through the water inlet pipe and reaches an inlet of the horn pipe of the water pump through a water inlet groove. The pump device is suitable for various shaft type water inlet modes, the formation ofvortexes can be reduced to make the water flow more smoothly, the overall performance of the pump device is obviously improved, the energy is saved, and the consumption is reduced.

Description

technical field [0001] The invention relates to a shaft type pump device with an annular water inlet tank, which belongs to the technical field of water conservancy engineering. Background technique [0002] With the acceleration of the country's urbanization process and the construction of various infrastructures across the country, wastewater in more and more areas cannot be discharged, which requires pumping stations to lift and transport. Wellbore pumping stations emerged as the times require, especially in the field of municipal engineering has been widely used. The shaft type pumping station is composed of water pumps, pipelines, valves and so on. The main body is usually a composite winding glass fiber reinforced plastic cylinder, which has good corrosion resistance. However, in this shaft-type water inlet form, the water flow is often turbulent during the process of entering the well from the water inlet pipe, and it is easy to form a vortex, resulting in poor wate...

Problems solved by technology

However, in this wellbore water inlet form, the water flow is often turbulent when it enters the well from the inlet pipe, and it is easy to form a vortex, which leads to poor water inlet conditions for the impeller.
