Abstract
The utility model discloses a pulp pump impeller. Including blade, front shroud, back shroud and corresponding impeller drum, the blade includes three main lobe pieces of mutual symmetrical evenly distributed and is located three corresponding back blades in the back shroud outside, the crooked opposite direction of its crooked direction of back blades and corresponding main lobe piece. This pulp pump impeller simple structure, reasonable, operation, balanced, stable, reliable, long service life.
Description
Technical field
The utility model relates to a kind of pump series products, particularly relates to a kind of pulp pump impeller carried for pulp liquor or clear water.
Background technique
For in paper industry production process, the impeller channel structure of the pump of conveying paper pulp adopts open architecture, or adopt enclosed single channel or two blade impeller, although the impeller of said structure solve impeller at work paper pulp impurity blocking problem, but it is thick greatly in use to there is back shroud of impeller in single blade impeller, vane thickness is thick greatly, makes impeller weight very heavy, increases movement load.
Its symmetry properties of the impeller of this structural feature is poor, make impeller balance when circling inadequate, operationally strong vibration can be produced to making water pump, noise is large, water pump upper bearing (metal) is caused a devastating effect, seriously up to making water pump not work, need often repair or replace new pulp pump to water pump, affecting user and using.Up to the present to single blade impeller, also comprise two blade impeller and also there is no ideal solution.
Model utility content
The purpose of this utility model is exactly the deficiency existed for prior art, provides a kind of pulp pump impeller.This pulp pump blade wheel structure is simple, rationally, to run, balance, stable, reliable, long service life.
The technological scheme of the utility model pulp pump impeller comprises blade, front shroud, back shroud and corresponding impeller drum, corresponding three back blades that described blade comprises equally distributed three primary blades symmetrically and is positioned at outside described back shroud, its bending direction of described back blades is contrary with the bending direction of corresponding primary blades.
Described primary blades and back blades are connected into by multistage R smoothed curve respectively.
Described primary blades thickness is thickeied to Exit-edge gradually by inlet side.
The external diameter of described primary blades is 290mm, and water intake diameter is 90mm, and water outlet width is 50mm, front/rear cover plate thickness 5 ~ 6mm.
Its import laying angle of described primary blades 23 degree, blade exit laying angle 28 degree, subtended angle of blade 78 degree.
The external diameter of described front shroud and blade is less than the external diameter of back shroud.
The utility model pulp pump impeller is due to the rationality of its structure, and its runner is wide, and without blocking, when impeller works, do circumferencial direction rotation and can reach balance, friction, noise is low, carries the pulp liquid with impurity not only effective, and durable.
Accompanying drawing explanation
Fig. 1 is the impeller axial plane sectional view of the utility model pulp pump impeller one embodiment; Fig. 2 is impeller primary blades and the back blades plane structure schematic diagram of Fig. 1; Fig. 3 is Impeller trim primary blades in Fig. 1 and front shroud outside diameter structure schematic diagram.
Embodiment
Implement new technique scheme to understand further, following instance is described further the utility model by reference to the accompanying drawings:
As Figure 1-3, the impeller of the present embodiment comprises front shroud 3, symmetrically equally distributed three primary blades 5, back shroud 4, and corresponding three back blades 6 be positioned at outside back shroud 4 and corresponding impeller drum etc.Its bending direction of back blades 6 is contrary with the bending direction of corresponding primary blades 5.
Primary blades 5 is connected and composed by multistage R smoothed curve.Primary blades 5 thickness is thickeied to Exit-edge gradually by inlet side.Its import laying angle of primary blades 23 degree, blade exit laying angle 28 degree, subtended angle of blade 78 degree.
The external diameter of front shroud 3 and blade is less than the external diameter of back shroud 4.
The external diameter of blade and front and rear cover plate is 290mm, and water intake diameter is 90mm, and water outlet width is 50mm, front/rear cover plate thickness 5 ~ 6mm.
The axis hole 7 of impeller loads on paper pulp pump shaft, pump shaft, vane rotary is driven by motor, pulp liquid sucks from suction port 1, by impeller, pulp liquid is done work, and the runner between primary blades flows out to impeller exhaust port, make pulp liquid add energy, reach required flow and lift demand.
Front shroud 3 and back shroud 4 form the runner that liquid flows through, and suction port 1 is made up of the cylindrical hole of front shroud 3, and exhaust port 2 is by looping three outlets such as front shroud 3 and back shrouds 4.Three primary blades 5 connect one for body with front shroud 3, back shroud 4, back blades 6 and back shroud 4 are connected as one, and seal ring seam 8 is made up of the ring-shaped cylinder of front shroud 3.Impeller is manufactured by cast iron or cast steel material.
In order to meet the demand of the different operating mode of different user, can cut impeller outer diameter, this impeller carries out cutting external diameter to front shroud 3 and primary blades 5, ensures back shroud and back blades size constancy, can play fed sheet of a media guide functions and raise the efficiency.
Fig. 3 be Impeller trim blade and front shroud external diameter to 200mm size view, impeller outer diameter can carry out different specification size cutting between 290mm and 200mm, and scope of cutting is large, realizes the requirement of different flow and lift, expands using scope.Primary blades 5 and front shroud 3 ratio of cutting reach 31%, are greater than the scope of usual low specific speed cutting than 20%.
Its Impeller Design performance parameter: flow Q:70 ~ 40m3/h, Yang Cheng H:27-18mm, rotating speed N:1450-1480r/min, passes through particle diameter: 45mm, complete motor power: 11-4KW.Specific speed Ns=62.5.The utility model impeller weight is light, compares, weight saving 2/3-1/2 with original single blade (single channel) impeller; Save material, reduce manufacture cost.
