Description
Technical field
The present invention relates to pump technology field, especially relate to a kind of centrifugal pump impeller.
Background technique
Centrifugal pump is the most common water pump.Conventionally, centrifugal pump comprises the housing with water intake and water outlet, is provided with power and is connected to the impeller of motor in this housing.Its defect is: at a moment starting, the moment of torsion that need to overcome due to impeller is larger, thereby very easily causes burning of motor, and then not only impeller is easy to damage, and the working life of having reduced motor.
Summary of the invention
The object of this invention is to provide a kind of centrifugal pump impeller, it has not fragile, and the feature that can extend the working life of motor.
The technical solution adopted in the present invention is: centrifugal pump impeller, comprise body, and this body has axis, and this axis inside is provided with the axis hole that runs through this axis left and right,
Described centrifugal pump impeller also comprises lobus sinister sheet and lobus dexter sheet;
The left surface of described body is provided with the chute of outwards dispersing, and the right part of this lobus sinister sheet is provided with fixture block, and this fixture block and this chute match, and this lobus sinister sheet is furnished with the Zola's spring that makes this lobus sinister sheet have the trend of close this axis;
The right flank of described body is provided with annular receiving cavity, this lobus dexter sheet slides and is arranged in this receiving cavity, and this lobus dexter sheet is sheathed on the right part of this axis, this lobus dexter sheet is furnished with makes this lobus dexter sheet have the right extension spring to left dislocation trend, simultaneously, in this receiving cavity, be provided with at least 1 top nose, this top nose has the outer arm and the inner arm that are parallel to each other, the left end of this outer arm and the left end of this inner arm couple together by link arm, this link arm is hinged in this receiving cavity, and the right-hand member of outer arm is fixed with weighted spherical ball, the right-hand member of this inner arm withstands on the left surface of this lobus dexter sheet.
The two ends of described Zola's spring are connected on this lobus sinister sheet and this axis.
The two ends of described right extension spring are connected on the left surface of this lobus dexter sheet and the left surface of this receiving cavity.
The outer end of described chute is provided with outward extending through hole.
The advantage that the present invention has is: not fragile, can extend working life of motor.Use the centrifugal pump of centrifugal pump impeller of the present invention at the beginning of starting, due to lobus sinister sheet near axis, lobus dexter sheet the left side wall near receiving cavity, thereby there is less external diameter and less thickness, then the required moment of torsion overcoming is less, reduce the probability that this impeller damages, also reduced the probability that motor damages.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1.
In figure: 10, body, 11, axis, 111, axis hole, 12, chute, 121, through hole, 13, receiving cavity; 20, lobus sinister sheet, 21, fixture block; 30, Zola's spring; 40, lobus dexter sheet; 50, top nose, 51, outer arm, 511, weighted spherical ball, 52, link arm, 53, inner arm; 60, right extension spring.
Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: centrifugal pump impeller, comprises body 10.This body 10 has axis 11, and these axis 11 inside are provided with the axis hole 111 that runs through these axis 11 left and right, and this axis hole 111 is interior can be provided with keyway.Further say, this centrifugal pump impeller also comprises lobus sinister sheet 20 and lobus dexter sheet 40.The left surface of this body 10 is provided with the chute 12 of outwards dispersing., what this chute 12 was flat is multiple, and the elongation line of each chute 12 is all by the shaft axis of this axis 11.The right part of this lobus sinister sheet 20 is provided with fixture block 21, and this fixture block 21 and this chute 12 match., this fixture block 21 is stuck in this chute 12 and can slides.Obviously, the section of this chute 12 and this fixture block 21 all can be " T " font.This lobus sinister sheet 20 is furnished with makes this lobus sinister sheet 20 have the Zola's spring 30 near the trend of this axis 11.Like this, at the beginning of this vane rotary, this lobus sinister sheet 20 is near this axis 11, thereby makes to drive the motor of this impeller without overcoming larger moment of torsion.When after rotation, under the effect of centrifugal force, this lobus sinister sheet 20 is away from this axis 11, thereby makes this impeller have larger drainage capacity.
The right flank of this body 10 is provided with annular receiving cavity 13.Obviously, these receiving cavity 13 and these axis 11 coaxial inner conductors.This lobus dexter sheet 40 slides and is arranged in this receiving cavity 13, and this lobus dexter sheet 40 is sheathed on the right part of this axis 11., this lobus dexter sheet 40 can horizontally slip along this axis 11.This lobus dexter sheet 40 is furnished with makes this lobus dexter sheet 40 have the right extension spring 60 to left dislocation trend.Meanwhile, in this receiving cavity 13, be provided with at least 1 top nose 50.This top nose 50 has the outer arm 51 and the inner arm 53 that are parallel to each other, and the left end of the left end of this outer arm 51 and this inner arm 53 couples together by link arm 52., this top nose 50 is fish hook shape.This link arm 52 is hinged in this receiving cavity 13, and the right-hand member of this outer arm 51 is fixed with weighted spherical ball 511 prepared by the materials such as plumbous matter, and the right-hand member of this inner arm 53 withstands on the left surface of this lobus dexter sheet 40.Like this, at the beginning of this vane rotary, this lobus dexter sheet 40, near left side, makes this impeller have less thickness, and motor is without overcoming larger moment of torsion then.When after this vane rotary, under the effect of centrifugal force, this weighted spherical ball 511 outwards throws away and away from this axis 11, thereby the displacement to the right of the right-hand member of this inner arm 53 heads on this lobus dexter sheet 40 displacement to the right then, makes this impeller have larger drainage capacity.
Optimize, the two ends of this Zola's spring 30 are connected on this lobus sinister sheet 20 and this axis 11, and the two ends of this right extension spring 60 are connected on the left surface of this lobus dexter sheet 40 and the left surface of this receiving cavity 13.Like this, be convenient to the assembling of this Zola's spring 30 and this right extension spring 60.
Continue to optimize, the outer end of this chute 12 is provided with outward extending through hole 121.Like this, avoided these chute 12 inside to occur causing this impeller cannot realize dynamically balanced phenomenon after ponding.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
