Description
Technical field
The invention belongs to magnetic drive pump isolation cover technical fields, and in particular to a kind of combined magnetic force pump isolation cover.
Background technique
Magnetic drive pump has the characteristics that No leakage, without sealing, is widely used in inflammable and explosive wait in chemical process flows, magnetic force
Pump, at master and slave magnet rotor, drives impeller to reach conveying technique and is situated between using inside and outside two magnetizers and the set of permanent magnets being arranged on
The purpose of matter, when motor drives the rotation of active magnet rotor, the magnetic torque that can be generated each other by permanent magnet in inside and outside magnet rotor
Realize the synchronous rotary of two building blocks, in the specific use process, can convey containing trace impurity, interior flushing exist compared with
The effect of Maelstrom power be easy to cause bottom perforation on duty leakage to fail, and seriously affects being carried out continuously for equipment and process system, is
Under the conditions of bad working environments, reduce interior media whirlpool power, it is existing by isolation cover bottom increase centrum strong bottom by
Vortes interference, but also need to be further improved.
Summary of the invention
The purpose of the present invention is being directed to existing issue, a kind of combined magnetic force pump isolation cover is provided.
The present invention is achieved by the following technical solutions: a kind of combined magnetic force pump isolation cover, including cover, on cover
Equipped with installation edge, the cover bottom centre position is equipped with column type empty slot, is equipped with internal screw thread in column type empty slot；It is equal outside column type empty slot
Even to be distributed multiple spiral salients smoothly reduced by center to outside height, the center at the top of the spiral salient is equipped with spiral shell
Rotary stall item；
Further include choked flow hollow sphere, be column type interconnecting piece below choked flow hollow sphere, column type interconnecting piece outer end is equipped with and interior spiral shell
The external screw thread that line matches；It is hollow hemisphere above choked flow hollow sphere, uniformly leads to by circle distribution circle in hollow hemisphere
Hole.
As further improvement of these options, the width of the spiral salient by column type empty slot extroversion cover outer wall by
It is decrescence small.
As further improvement of these options, the diameter of circular through hole is by far from cover bottom in the hollow hemisphere
Portion is gradually reduced to close to cover bottom.
As further improvement of these options, there is no circular through hole at the top of the hollow hemisphere.
As further improvement of these options, the quantity of the spiral salient is 3-8.
As further improvement of these options, the diameter of the circular through hole is 1-4mm.
As further improvement of these options, the distance between the circular through hole in same level height is greater than the water
The diameter of flat height circular through hole.
As further improvement of these options, the choked flow hollow sphere is raw material note by polyether-ether-ketone and PVC plastic
Moulding at.
As further improvement of these options, the addition in the polyether-ether-ketone injection raw material is than being its total weight
18-24%。
The present invention, which is had the advantage that compared with prior art in the present invention, is arranged choked flow hollow sphere in cover bottom, can
It effectively prevent occurring whirlpool power in isolation cover, the circular through hole on choked flow hollow sphere can effectively divide interior media from all directions
In the choked flow hollow sphere of stream, impact force is greatly reduced, external spiral shape protrusion will further not enter in choked flow hollow sphere
Medium shunt, multiple action effectively decompose the whirlpool power of interior media, which are used to the isolation for being easy to appear whirlpool power
In cover, run 18 months, do not occur due to whirlpool power generate adverse consequences, operating index stability is good, at runtime between compared with
It is long, since dielectric corrosion effect damages choked flow hollow sphere, replace choked flow hollow sphere.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the structural schematic diagram of choked flow hollow sphere.
Fig. 3 is top view of the invention.
Fig. 4 is the perspective view of isolation cover bottom.
Specific embodiment
The following further describes the present invention with reference to the drawings.
As shown in figs. 1-4, a kind of combined magnetic force pumps isolation cover, including cover 1, and cover 1 is equipped with installation along 2, institute
1 bottom centre position of cover is stated equipped with column type empty slot 3, column type empty slot 3 is interior to be equipped with internal screw thread 31；It is uniformly distributed outside column type empty slot 3
The center of multiple spiral salients 4 smoothly reduced by center to outside height, 4 top of spiral salient is equipped with spiral shelves
Item 41；
Further include choked flow hollow sphere 5, is column type interconnecting piece 52 below choked flow hollow sphere 5,52 outer end of column type interconnecting piece is equipped with
The external screw thread 521 to match with internal screw thread 31；It is hollow hemisphere 51 above choked flow hollow sphere 5, in hollow hemisphere 51 uniformly
By circle distribution circular through hole 511.
As further improvement of these options, the width of the spiral salient 4 is by the export-oriented cover outer wall of column type empty slot 3
It is gradually reduced；In the hollow hemisphere 51 diameter of circular through hole 511 from far from cover bottom to close to cover bottom gradually
Reduce；There is no circular through hole 511 at the top of the hollow hemisphere.
Wherein, the quantity of the spiral salient 4 is 7；The diameter of the circular through hole 511 is 1-4mm.
As further improvement of these options, the distance between circular through hole 511 in same level height is greater than
The diameter of the level height circular through hole 511；
The choked flow hollow sphere 5 is molded for raw material by polyether-ether-ketone and PVC plastic and is formed；The polyether-ether-ketone injection raw material
In addition than be its total weight 18-24%.
It is calculated by numerical value repeatedly and obtains the form structure that can decompose interior media whirlpool power, this hair with repetition test
Choked flow hollow sphere 5 is set in cover bottom in bright, can effectively prevent occurring whirlpool power in isolation cover, on choked flow hollow sphere 5
Circular through hole 511 can greatly reduce impact force by interior media out of all directions effectively shunt choked flow hollow sphere 5, external
Spiral shape protrusion 4 will further not enter the medium shunt in choked flow hollow sphere 5, interior media is effectively decomposed in multiple action
The invention is used and is easy to appear in the isolation cover of whirlpool power by whirlpool power, is run 18 months, does not occur generating due to whirlpool power
Adverse consequences, operating index stability is good, at runtime between it is longer, due to dielectric corrosion effect choked flow hollow sphere is caused to damage
It is bad, choked flow hollow sphere is replaced, it is easy to use, it is easy to spread.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
