The semi-open impeller comprises a fixing and installing base (1) for installing and fixing, wherein the fixing and installing base (1) is provided with blades (2) which are distributed along the center of the axle center of the fixing and installing base (1); one side of the axle center of the fixing and installing base (1) is provided with a fixing and installing hole (11); the other side of the axle center of the fixing and installing base (1) is provided with a fluid inlet and outlet hole (2); one side the fixing and installing base (1) which is close to the fluid inlet and outlet hole (12) is provided with a diversion hole (13); and the fluid inlet and outlet hole (12) is communicated with the working surface of the blades (2) through the diversion hole (13). The semi-open impeller has the advantages of small axial distance, simple and compact structure and strong output force.
Description
Technical field
The utility model relates to the transfer pump field, is specifically related to a kind of semi open model impeller that is used for centrifugal transfer pump.
Background technique
As the special device of carrying liquid, centrifugal transfer pump has obtained using widely at present.The main flow passage components of centrifugal transfer pump have suction chamber, impeller and pumping chamber.Suction chamber is positioned at the water intake front of impeller, plays the effect of guiding liquid in impeller; Pumping chamber mainly contains spirality pumping chamber (scroll casing type), stator and three kinds of forms of spatial guide blade; Impeller is the most important work element of pump, is the heart of flow passage components, and impeller is made up of cover plate and middle blade.Before the centrifugal pump work,, start centrifugal pump then earlier with full of liquid in the pump; Impeller quick rotation, the blade of impeller are ordered about liquid and are rotated, and rely on inertia to the impeller outer edge diffluence when liquid rotates; Impeller is from suction chamber inspiration liquid simultaneously, and in this course, the liquid in the impeller streams blade; Liquid effects one lift is in blade in streaming motion, conversely blade with one therewith lift equal and opposite in direction, masterpiece in the opposite direction be used for liquid, this power is done work to liquid; Make liquid obtain energy and flow out impeller, at this moment the kinetic energy of liquid and pressure energy all increase.Centrifugal pump relies on rotary blade that the effect of liquid is passed to liquid to the mechanical energy of prime mover.Because the effect liquid of centrifugal pump flows to the process of outlet from impeller inlet, its speed can all obtain increasing with pressure, the liquid process delivery chamber of being discharged by impeller; Most of speed can convert the pressure ability to, transfers out along discharge conduit then, at this moment; The impeller inlet place forms vacuum or low pressure because of the discharge of liquid, and the liquid in the priming reservoir is pressed into the import of impeller under the effect of liquid level pressure (barometric pressure); So the impeller that is rotating just constantly sucks and drain continuously.
But the general structure of the impeller of the centrifugal transfer pump of existing technology is long, and the space that causes centrifugal transfer pump on thickness direction, to occupy is bigger, thus can not with the volume of centrifugal transfer pump do less, influenced the promotion and application scope of centrifugal transfer pump.
Summary of the invention
The technical problem that the utility model will solve provides the semi open model impeller that is used for centrifugal transfer pump that a kind of axial distance is little, simple and compact for structure, ouput force is big.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of semi open model impeller that is used for centrifugal transfer pump; Comprise the fixed mounting that is used to install and fix; Said fixed mounting is provided with along the blade of the axle center central distribution of fixed mounting, and a side in the axle center of said fixed mounting is provided with the fixed installation hole, and the opposite side in said fixed mounting axle center is provided with the fluid access hole; Said fixed mounting leans on a side of fluid access hole also to be provided with pod apertures, and said fluid access hole keeps being communicated with the working surface of said blade through pod apertures.
Further improvement as technique scheme:
Be provided with 5 blades on the said fixed mounting altogether, and said blade be shaped as the involute shape.
Said fixed mounting also is provided with 5 stiffening ribs away from a side of deflector access hole, and said 5 stiffening ribs are along the radial arrangement of said fixed mounting.
The utlity model has following advantage:
The utility model comprises the fixed mounting that is used to install and fix; Fixed mounting is provided with along the blade of the axle center central distribution of fixed mounting; One side in the axle center of fixed mounting is provided with the fixed installation hole, and the opposite side in fixed mounting axle center is provided with the fluid access hole, and fixed mounting leans on a side of fluid access hole also to be provided with pod apertures; The fluid access hole keeps being communicated with the working surface of blade through pod apertures, has the advantage that axial distance is little, simple and compact for structure, ouput force is big.
