The utility model adopts the pressurizing and flow-increasing structure which is additionally arranged outside the vane wheel, so as to greatly quicken the exhaust function of the pump body, thereby improving the self-priming function and reducing the loss of energy consumption; the vane wheel, the shell and a guide vane sleeve are made of fluorine plastic and alumina ceramic materials, which have the advantages of excellent high temperature resistance, corrosion resistance and abrasion resistance.
Description
Technical field
The utility model relates to a kind of self-priming pump, is a kind of high-effect self-priming pump specifically, belongs to the industrial pump technical field.
Background technique
Self-priming pump is a kind of equipment for liquid transportation, mainly comprise the pump housing, housing, impeller etc., in the market self-priming pump adopts be the barrier film exhaust mode, agent structure is that the pattern of centrifugal pump adds the barrier film exhaust, and it is in operation process, and period of exhaust is long, energy loss is big, so its efficient and self-absorption function are all very low, so that steam-water separator can only be installed additional at the delivery side of pump position in many manufacturers, but this can not solve root problem, has increased cost of production on the contrary.And corrosion-resistant self-priming pump ubiquity defectives such as pump body structure complexity, self-priming time is long, efficient is low.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide that a kind of self-absorption function is strong, efficient is high, processing is simple, installation and high-effect self-priming pump easy to maintenance.
Technological scheme: a kind of high-effect self-priming pump, comprise housing and impeller, in housing, be provided with impeller, the stator shell is installed on the impeller in housing, described stator shell one end face is provided with water intake, the other end is provided with the mounting hole that is sleeved on the impeller, and the side of stator shell is provided with runner and water inlet.
Described stator shell is installed with impeller is concentric.
Described runner has certain inclination angle.
The direction at described runner inclination angle is identical with the impeller rotation direction, be all counterclockwise or dextrorotation to.
The split type shell of described housing for ease of installing.
The liquid that enters from pump housing liquid entering hole, owing to being inhaled into for negative pressure in the pump housing, impeller is high speed rotating under the drive of motor, the stator shell that is sleeved on impeller outer maintains static, this stator has a runner, because suit one stator shell again on original impeller, strengthened the coherency of liquid in the pump housing greatly, when pump housing impeller during, after coming out from impeller channel, liquid, goes out through the runner eddy effusion of stator shell again through the stator shell at rotary work, this just is equivalent to install a current accelerator additional to the pump housing, the degassing function of the pump housing is accelerated greatly, thereby improved self-absorption function, reduced the loss of energy consumption.The interior degassing function of the pump housing is accelerated greatly, thereby improved the power that its liquid is discharged.What wherein the material of impeller, stator shell and housing etc. and liquid contacting part position adopted is fluoroplastic and two kinds of materials of aluminium oxide ceramics.Fluoroplastic mainly contain ultra-high molecular weight polyethylene and vinylidene fluoride, perfluoroethylene-propylene etc.As everyone knows, fluoroplastic are the preferred materials to anticorrosive property liquid, almost for all corrosive liquids corrosion-resistant function are arranged all.Aluminium oxide ceramics then is to adopt the aluminium oxide 99% or more to form through high temperature sintering, also has high temperature resistant, the corrosion resistance and the wear resistance of excellence.
Beneficial effect: (1) pump housing adopts split-type design, becomes simple, convenient in the processing of the pump housing, mold pressing, assembling, the maintenance; (2) the impeller outside adds the incremental structure of pressurization, and promptly the stator shell is accelerated the degassing function of the pump housing greatly, and efficient improves 10 percentage points, and has improved self-absorption function, has also just improved efficient, has reduced by nearly 1/3rd energy consumption, has saved the energy; (3) fluoroplastic and alumina ceramic materials are all adopted in stator shell and other and liquid contacting part position, have excellent high temperature resistant, corrosion resistance and wear resistance.(4) and this stator shell separate with the pump housing, easily processing and assembling and maintenance, thus alleviated difficulty of processing, easier grasp machining accuracy.And effectively protected the miscellaneous part of the pump housing, even there are parts damages also can not have influence on the whole pump housing, saved maintenance cost and alleviated maintenance difficulty.
