Description
Technical field
The present invention relates to a kind of pump more particularly to a kind of mixed-flow pumps.
Background technique
Mixed-flow pump is a kind of pump between centrifugal pump and axial-flow pump.The specific speed of mixed-flow pump is higher than centrifugal pump, is lower than
Axial-flow pump, generally between 300-500.Its lift is higher than axial-flow pump, but flow-rate ratio axial-flow pump is small, bigger than centrifugal pump.Work as original
After the rotation of motivation impeller, there is axial thrust again to the existing centrifugal force of the effect of liquid, is the synthesis of centrifugal pump and axial-flow pump,
The oblique outflow impeller of liquid.Therefore it is a kind of pump between centrifugal pump and axial-flow pump.It has centrifugal pump concurrently and axial-flow pump is excellent
Point, structure is simple, and high efficient district is wide, easy to use.
Chinese invention patent (201320412771.2 applying date 2013.07.11 of application number) discloses a kind of mixed flow
Pump comprising have the shell of setting cylindrical in shape, the side wall of the shell offers multiple feeding inlets, and the upper end of the shell is equipped with
One discharge port is equipped with an axial screw spinning roller within the shell and a radial rotary wheel, the mixed-flow pump further includes having for driving
Axial screw spinning roller and the driving device of radial rotary wheel operating, the axial screw spinning roller is located within the radial rotary wheel and the two
It is directed toward axial screw spinning roller, the trend power side of the axial screw spinning roller in the trend power direction of concentric setting, the radial rotary wheel
To direction discharge port.
Chinese utility model patent (201320140348.1 applying date 2013.03.26 of application number) discloses a kind of mixed
Stream pump, including impeller, the left side of impeller are connected by shaft coupling with small trochal disc；Small trochal disc is connected by belt with big trochal disc
It connects；The two sides of big trochal disc are provided with foot pedal；It is provided with vehicle seat above big trochal disc, is provided with handle in front of vehicle seat.
Summary of the invention
Existing fluid foods transfer tube is mostly centrifugal pump, by the high speed rotation of its internal impeller by fluid foods
It is continuously drawn into and extrudes, which wants gas in drain pump in prestart, so being easy to appear gas if misoperation
Tiing up phenomenon can not come into operation, so reliability is poor, meanwhile, the viscosity of fluid on the driving capability of centrifugal pump influence compared with
Greatly, and most of centrifugal pumps are only used for the liquid that viscosity is similar to water, are used for trandfer fluid cement so working as centrifugal pump, dissipate
When the materials such as material, by serious curtailment lift.For existing equipment and the deficiency of technology, the invention reside in providing a kind of mixed-flow pump,
Its structure is simple and convenient to operate, is low in cost, strong applicability.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of mixed-flow pump, the mixed-flow pump are combined by housing parts and pump body portion, mainly by shape shell, import straight tube, suction
Enter the composition such as loudspeaker, impeller, the pump housing and guide vane；The mixed-flow pump pump body portion is by impeller, the pump housing, axis, bearing and guide vane group
At；The mixed flow pump bearing and axle sleeve are separately positioned on the periphery of pump shaft front-end and back-end；The impeller setting is pumping
It is connected in vivo and with axle sleeve；The suction bell is connected with water inlet；The mixed-flow pump is using radial water flowing out structure.
As a preferred solution of the present invention, the tubaeform ectosome of the mixed-flow pump uses stainless steel structure.
As a preferred solution of the present invention, the mixed-flow pump number of blade is 2, and guide vane number is 7.
As a preferred solution of the present invention, the axis, bearing are connected with blade, guide vane.
As a preferred solution of the present invention, the water inlet completes the entrance of liquid, and by storing after blade
In pulse water tank.
As a preferred solution of the present invention, the static pressure that the pulse water tank needs provides static pressure and flow by pump.
The invention has the advantages that simple configuration diesel engine or diesel oil Multi-Cylinder Diesel Engine can be selected when the device use,
And use vacuum chamber, prevent in air sucking mixed-flow pump and prevent water from flowing out too much along axis out of mixed-flow pump, big flow is low to raise
Journey, have many advantages, such as it is structurally reasonable, using reliable, maintenance is convenient and high-efficient, small in size, light-weight.
Detailed description of the invention
In order to which the technical problems, technical solutions and beneficial effects solved by the present invention is more clearly understood, below in conjunction with
The drawings and the specific embodiments, the present invention will be described in further detail.
Fig. 1 is the structural diagram of the invention.
1- water outlet, 2- guide vane, 3- blade, 4- suction bell, 5- water inlet in figure.
Specific embodiment
In Fig. 1, a kind of mixed-flow pump, the mixed-flow pump is combined by housing parts and pump body portion, mainly by shape shell,
The composition such as import straight tube, suction bell, impeller, the pump housing and guide vane；The mixed-flow pump pump body portion is by impeller, the pump housing, axis, axis
It holds and guide vane forms；The mixed flow pump bearing and axle sleeve are separately positioned on the periphery of pump shaft front-end and back-end；The leaf
Wheel is arranged in the pump housing and is connected with axle sleeve；The suction bell is connected with water inlet；The mixed-flow pump is using radial
Water flowing out structure.
The composite mechanical hand working method are as follows: present apparatus diffuser and outlet structure and common mixed-flow pump exist
Bigger difference is discharged after the guide vane of common mixed-flow pump can convert pressure energy for the speed of fluid by outlet elbow, and the special type
The feature of mixed-flow pump model maximum is that liquid enters pulse water tank from diffuser surrounding after guide vane, obtains pulse water tank
The static energy that must be needed is to push transmitting.
It is understood that being merely to illustrate the present invention above with respect to specific descriptions of the invention and being not limited to this
Technical solution described in inventive embodiments, those skilled in the art should understand that, still the present invention can be carried out
Modification or equivalent replacement, to reach identical technical effect；As long as meet use needs, all protection scope of the present invention it
It is interior.
