Detailed description of the invention
A kind of centrifugal pump structure schematic diagram for accelerating water speed out of Fig. 1 present invention,
Fig. 2 is blade wheel structure schematic diagram,
Fig. 3 be in Fig. 2 A-A to structural schematic diagram,
Fig. 4 is B-B direction structural schematic diagram in Fig. 2.
Specific embodiment
For convenient for those skilled in the art understand that technical solution of the present invention, now in conjunction with Figure of description to the technology of the present invention side
Case is described further.
As shown in Figures 1 to 4, a kind of centrifugal pump for accelerating water speed out, including spiral case 1 and impeller 2, after impeller 2 includes
Side plate 11 and front side board 12 are provided with blade 13, side of the front side board 12 far from back side panel 11 between back side panel 11 and front side board 12
Backboard 14 is provided on face；Back side panel 11, front side board 12 and the integrally-built design of blade 13 therebetween, increase centrifugal pump and raise
Journey is effectively increased pump housing liquid outlet pressure, improve pressure and speed of the liquid after liquid outlet flows out；And backboard 14
Design, backboard 14 drives fluid motion, and backboard 14 is surging to apply an angular speed to fluid, so that fluid is with certain angle
Speed flows outwardly, and further increases liquid lift, while also increasing the power of the pump housing.
Such as Fig. 1 and Fig. 2, be provided between front side board 12 and back side panel 11 spacing, 13 width of blade and front side board 12 and after
11 spacing of side plate are adapted, and 13 two sides of blade are detachably connected with front side board 12 and 11 side of back side panel respectively；Blade 13
Dismountable installation connection, convenient for the installation and maintenance or replacement to impeller 2, maintenance cost is low, long service life.
Such as Fig. 2 and Fig. 3,13 outer end of blade extends to 2 outer edge of impeller, and 13 outer end of blade is set as arc-shaped 15,
Blade 13 is obliquely arranged between back side panel 11 and front side board 12, and 13 tilt angle of blade is consistent with 2 direction of rotation of impeller,
Blade 13 is provided with 4, and is uniformly arranged between back side panel 11 and front side board 12；The design of this structure, blade 13 is with leaf
Wheel rotation, so that forming a vacuum area between impeller and spiral case 1, vacuum area draws fluid into the pump housing and by it by liquid
The conveying of fluid is realized in outlet discharge, and the main function of blade 13 is the vacuum degree increased in vacuum area, increases pump housing convection current
The absorption ability of body accelerates fluid motion speed, i.e. increasing pump body liquid discharge liquid speed degree.
Such as Fig. 2 and Fig. 4, backboard 15 is fixedly connected with front side board 12 far from the side of back side panel 11, and backboard 14 is in the shape of a spiral
Be arranged on front side board 12, and the hand of spiral is consistent with 2 direction of rotation of impeller, and backboard 14 is provided with 6 pieces, backboard 14 with a thickness of
2.5mm；The angular speed of fluid one movement in inner spiral casing 1 is forced in the design of backboard 14, so that fluid is with angular speed from snail
Liquid outlet outflow on shell 1, the fluid of outflow move out under the action of angular speed, and lift increases, and power increases, so that pump
The efficiency of body entirety increases.
Technical solution of the present invention is exemplarily described invention above in conjunction with attached drawing, it is clear that present invention specific implementation
It is not subject to the restrictions described above, changes as long as using the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out
Into, or it is not improved the conception and technical scheme of invention are directly applied into other occasions, in protection scope of the present invention
