Description
Technical field
This utility model relates to a kind of impeller, more specifically, it relates to a kind of centrifugal pump impeller.
Background technology
Impeller had both referred to the wheel disc equipped with movable vane, was the ingredient of impulse turbine rotor.Changes mechanical energy operationally, owing to impeller and fluid occur friction to produce to rotate, is kinetic energy, and then makes centrifugal pump produce flow and lift by centrifugal centrifugal pump.The size of flow and lift is the important indicator judging centrifugal pump quality.
Existing common centrifugal pump impeller is one-dimensional flow impeller, and its runner is narrow, and vane twist is little, and hydraulic resistance is big, and efficiency is low and easy cavitation.For this problem, the Chinese patent that the patent No. is CN202560629U discloses a kind of centrifugal pump impeller, the impeller of centrifugal pump, including wheel hub and multiple blade, it is provided centrally with axis hole at wheel hub, it is characterised in that: described blade is three-dimensional flow parabolic blades, and the three-dimensional flow parabolic surface of blade is tilted to charging aperture direction gradually by discharging, inclination angle is 45 degree, and impeller protecgulum is corresponding with the curve of blade with the curve form of impeller bonnet.Being provided with the improvement to original impeller of the three-dimensional flow parabola catch in that patent, three-dimensional flow parabola catch arranges and has the advantage that the through-current capability improving impeller；Its exit width increases, and improves hydraulic efficiency；Three-dimensional flow parabola catch arranges and makes conduit wider, and impeller conduit water flow velocity reduces, it is possible to slows down cavitation phenomenons and occurs, and meanwhile, its inlet side always flows to mouth and stretches, and decreases entrance loss, improves cavitation performance.
But, the employing of three-dimensional flow parabola catch can reduce blade quantity, causes that the lift that centrifugal pump produces reduces.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of centrifugal pump impeller increasing centrifugal centrifugal pump lift.
For achieving the above object, this utility model provides following technical scheme: a kind of centrifugal pump impeller, including wheel disc and the three-dimensional flow parabolic blades being located at wheel disc upper surface, it is characterized in that, the upper surface of described wheel disc is additionally provided with fin, the shape of described fin is identical with the three-dimensional flow parabolic blades arc in wheel disc junction, is provided with multiple fin described in adjacent two between three-dimensional flow parabolic blades.
By adopting technique scheme, due to centrifugal pump lift not by the impact of blade height, the mode arranging fin between three-dimensional flow parabolic blades can reduce the impact that blade quantity minimizing causes centrifugal pump lift to reduce, and improves centrifugal pump lift.
This utility model is more preferably: fin between three-dimensional flow parabolic blades described in adjacent two is presented to set up along the direction height of projection of the bending of fin dorsad and put.
By adopting technique scheme, the impact that can reduce current to blade is set by this, slows down cavitation phenomenons further and occur.
This utility model is more preferably: the cross section of described fin becomes arc line shaped.
By adopting technique scheme, arc line shaped is arranged avoids fin that current shine into excessive resistance, severe impact occurs, reduces the current impact to blade further.
This utility model is more preferably: the three-dimensional flow parabolic surface of described three-dimensional flow parabolic blades is tilted to charging aperture direction gradually by discharging opening, and inclination angle is 45 degree.
By adopting technique scheme, this structure, closer to the flow behavior of fluid, makes liquid flowing be become three-dimensional by two dimensional motion, reduce fluid circulating loss in wheel cavity, friction loss and impact loss, avoiding reactive power, thus improving the efficiency of centrifugal pump, reaching energy-conservation purpose.
This utility model is more preferably: described three-dimensional flow parabolic blades surface is coated with nichrome powder layer.
By adopting technique scheme, improve corrosion resistance and the structural strength of three-dimensional flow parabolic blades, strengthen anti-cavitation performance, increase the service life.
In sum, this utility model centrifugal pump impeller has the centrifugal pump lift of raising, improves the efficiency of centrifugal pump, long service life and energy-conserving and environment-protective advantage.
