Abstract
The invention provides a vortex-resisting isolation hood for a magnetic pump. The vortex-resisting isolation hood comprises a hood body (1), wherein a vortex-resisting cone (2) is arranged on a bottom baffle plate of the hood body (1); at least two spiral flow guide grooves (2.1) are formed on the vortex-resisting cone (2); at least three vortex reduction grooves (1.1) are formed on the bottom baffle plate of the hood body (1); the vortex-resisting cone (2) is arranged at the central position of the bottom baffle plate of the hood body (1); the outer diameter of the bottom surface of the vortex-resisting cone (2) is one eighth to a half that of the bottom baffle plate of the hood body (1); and the cone angle of the vortex-resisting cone (2) is 30 to 150 DEG. When the magnetic pump is usedfor rotating internal media to generate vortex force, the vortex force can be effectively decomposed by the flow guide grooves, so that the problem of perforation of the bottom baffle plate caused byexcessively-concentrated vortex force on the bottom baffle plate is solved.
Description
Technical field
The present invention relates to the magnetic drive pump field, relate in particular to a kind of shielding can of magnetic drive pump, specifically refer to a kind of vortex-resisting isolation hood for magnetic pump.
Background technique
At present, straight connection type GT series magnetic drive pump is in the industrialization using process, and shielding can adopts substantially that flange is fixed, bottom baffle is the form of plane structure.Engineering practice confirms, existing straight connection type GT series magnetic drive pump shielding can when conveying contains micro-fine impurity, interior flushing exists than under the Maelstrom power bad working environments, cause easily bottom baffle perforation leakage failure under the effect of shielding can bottom baffle because of interior flushing liquid at high speed whirlpool power, had a strong impact on the continization operation of equipment and process system.
Therefore, for straight connection type GT series magnetic drive pump, in the urgent need under bad working environments and operational condition, reduce interior media whirlpool power to prevent further to embody the use advantage of magnetic drive pump because of the bottom baffle perforation.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of vortex-resisting isolation hood for magnetic pump of effectively reduced interior media whirlpool power is provided.
Technical solution of the present invention is, following a kind of vortex-resisting isolation hood for magnetic pump is provided, and comprises cover body, and the bottom baffle of described cover body is provided with anti-whirlpool cone, and described anti-whirlpool cone is provided with at least two spiral stream guidance grooves.
After adopting above scheme, vortex-resisting isolation hood for magnetic pump of the present invention is provided with anti-whirlpool cone at the bottom baffle of cover body, and cone is provided with at least two spiral stream guidance grooves in anti-whirlpool, like this when the inner medium of magnetic drive pump rotation produces whirlpool power, can whirlpool power effectively be decomposed by guiding gutter, thereby avoid too concentrating on because of whirlpool power the problem of the bottom baffle perforation that bottom baffle causes.
As improvement, the bottom baffle of described cover body is provided with at least three and subtracts the whirlpool groove.After the improvement, can further reduce the whirlpool power that guiding gutter decomposes on the cone of anti-whirlpool by subtracting the whirlpool groove, thus the problem that the bottom baffle of thoroughly having avoided producing owing to interior media whirlpool power is bored a hole.
As preferably, described anti-whirlpool cone is located at the central position of the bottom baffle of cover body.Because when rotated, the whirlpool power of interior media is concentrated the central position with the baffle plate baffle plate, and the central position that anti-whirlpool cone is arranged on the bottom baffle of cover body can be decomposed the whirlpool power that interior media produces to greatest extent.
As preferably, the external diameter of described anti-whirlpool facies basialis pyramidis be cover body the bottom baffle external diameter 1/8～1/2, the cone angle of described anti-whirlpool cone is 30 °～150 °.
Better, the external diameter of described anti-whirlpool facies basialis pyramidis be cover body the bottom baffle external diameter 1/4, the cone angle of described anti-whirlpool cone is 60 °.
Adopting above-mentioned preferred and better technological scheme, is can effectively decompose the external shape structure that interior media produces whirlpool power cone by what numerical calculation and repetition test drew.
As preferably, the radian of described spiral stream guidance groove 〉=90 ° and width 〉=1.0mm, the degree of depth of spiral stream guidance groove upper end is less than the degree of depth of lower end.Radian and geomery to the spiral stream guidance groove behind this preferred version have been done more excellent selection, on the one hand with guiding gutter can so that the impact that guiding gutter avoids the unexpected break-in because of decomposing force to cause when decomposing interior media whirlpool power also can effectively prolong on the other hand because the decomposition of whirlpool power causes the wearing and tearing to guiding gutter.
As preferably, the distance≤1.0mm on the top of the top of described spiral stream guidance groove and anti-whirlpool cone.Top distance and the distance between the pyramid tip of anti-whirlpool of described spiral stream guidance groove are more short better, but avoid destroying the vertex of a cone of anti-whirlpool cone, thereby should be in conjunction with the variation of the guiding gutter degree of depth when using, can so that interior media is concentrated the decomposition average with the whirlpool power at center, can not produce impact like this.
As preferably, the described width 〉=1.5mm that subtracts the whirlpool groove subtracts the degree of depth 〉=1.0mm of whirlpool groove 1.1
Better, the described whirlpool groove that subtracts is 12, the width that subtracts the whirlpool groove is that 2mm, the degree of depth are 1.5mm.
Adopting above-mentioned preferred and better technological scheme, is the form structure that subtracts the whirlpool groove by the whirlpool power of the interior media that decomposed by the spiral stream guidance groove numerical calculation and repetition test can effectively further decomposing of drawing.
As preferably, the spiral stream guidance groove that described anti-whirlpool cone is provided with is along the rounded array distribution of axis of anti-whirlpool cone, and what the bottom baffle of described cover body was provided with subtracts the whirlpool groove along the rounded array distribution of the axis of cover body.After adopting this preferred version, spiral stream guidance groove and subtract the whirlpool groove and be circular array and distribute, for interior media since the whirlpool power that rotation produces can decompose uniformly.
In sum, the present invention arranges anti-whirlpool centrum and subtracts the whirlpool groove at the bottom baffle of cover body, be provided with the spiral stream guidance groove on the centrum of anti-whirlpool, the whirlpool power that can effectively decompose interior media, through evidence, use magnetic drive pump after this technological scheme to move continuously 300 days not occur any because the adverse consequences that whirlpool power produces, operating index is reliable, has further improved stability, the continuity of magnetic drive pump operation.
