Abstract
The invention relates to the field of centrifugal pump components, in particular to an improved structure of a centrifugal pump impeller. The improved structure of the centrifugal pump impeller comprises blades, a tooth-shaped structure, blade cavity channels, arc-shaped edges, a bearing base part, a boss and grooves, wherein the impeller is provided with a plurality of groups of blades which form the tooth-shaped structure; the connecting positions of the blades are provided with the arc-shaped edges playing a role in buffering; the blades are provided with the blade cavity channels for conveying fluid; the bearing base part of the impeller has a double-layer boss structure; and the boss, which is positioned at the innermost side from a central shaft and is used for being connected with a bearing, is provided with axially-symmetric grooves.
Description
Technical field
The present invention relates to centrifugal pump assembly field, concretely, relate to a kind of improvement structure of centrifugal pump impeller.
Background technique
Centrifugal pump is when transmitting fluid; The impeller easy abrasion and the damage of centrifugal pump; And when transmission has the fluid of suspended sand grain, cause the gap enlargement of rotation blade and fixing-assembly easily, reduce the working efficiency of centrifugal pump; Damage the centrifugal pump original paper, particularly reduce the working life of impeller and impeller side wall liner cover easily.Solve this technical problem and adopt improvement impeller and associated component thereof usually, reduce the intrusion of leakage loss and fluid.
Impeller is passed to liquid as the critical component of centrifugal pump with the mechanical energy of prime mover, and hydrostatic pressure ability and kinetic energy through centrifugal pump are improved.Impeller is when work; The a part of highly pressurised liquid that leaves impeller can bleed in the both sides cavity between impeller and the pump case; Because of fluid intake place, impeller front side is a low pressure,, just produced the end thrust of pointing to the suction eye side so liquid effects is unequal in the pressure of the forward and backward both sides of impeller.This power makes suction eye side play, causes the wearing and tearing of impeller and pump case contacting point, causes the vibration of pump when serious, has destroyed the proper functioning of pump.
Summary of the invention
To above-mentioned technical problem, the purpose of this invention is to provide a kind of improvement structure of centrifugal pump impeller.
Technological scheme to be solved by this invention is following:
The present invention is made up of blade, tooth-shape structure, blade cavity, curved edge, support base, boss, groove; Have many group blades on the impeller; Blade is a tooth-shape structure; Joint between blade and the blade has the curved edge that is used for buffer function; Be useful on the blade cavity of conveyance fluid on the blade, the support base of impeller is double-deck boss structure, and the distance center axle is the most inboard is used for the groove that has axial symmetry on the boss with the bearing joint.
The invention has the advantages that: on blade, set up the blade cavity; Make fluid smoothly through impeller assembly, reasonably adopt the curved edge design, prevent blade injury; The double-deck boss of central axis and groove structure be fixing impeller better, makes it not eccentric in the rotary work process.
Description of drawings
Fig. 1 is a kind of drawing in side sectional elevation of improvement structure of centrifugal pump impeller.
Reference character shown in Figure 1 is following: blade 1, tooth-shape structure 2, blade cavity 3, curved edge 4, support base 5, boss 6, groove 7.
Embodiment
The present invention is made up of blade 1, tooth-shape structure 2, blade cavity 3, curved edge 4, support base 5, boss 6, groove 7; Have many group blades 1 on the impeller; Blade 1 is a tooth-shape structure 2; Joint between blade 1 and the blade 1 has the curved edge 4 that is used for buffer function; Be useful on the blade cavity 3 of conveyance fluid on the blade 1, the support base 5 of impeller is double-deck boss structure 6, and the distance center axle is the most inboard is used for the groove 7 that has axial symmetry on the boss 6 with the bearing joint.
The invention has the advantages that: on blade 1, set up blade cavity 3; Make fluid smoothly through impeller assembly, reasonably adopt the curved edge design, prevent blade 1 damage; The double-deck boss 6 of central axis and groove 7 structures are fixing impeller better, makes it not eccentric in the rotary work process.
