Description
Technical field
The invention belongs to magnetic drive pump cage technical field, and in particular to a kind of combined magnetic force pump cage.
Background technology
Magnetic drive pump have No leakage, without sealing the features such as, it is inflammable and explosive wait chemical process flow in widely use, magnetic force
Pump utilizes inside and outside two magnetic conductors and the set of permanent magnets being arranged on into master and slave magnet rotor, and driving impeller reaches that conveying technique is situated between
The purpose of matter, when motor drives the rotation of active magnetic rotor, the magnetic torque that can be each other produced by permanent magnet in inside and outside magnet rotor
Realize the synchronous rotary of two building blocks, during specifically used, can convey containing trace impurity, interior flushing exist compared with
Maelstrom power is acted on, and is easily caused bottom perforation leakage failure on duty, is had a strong impact on being carried out continuously for equipment and process system, be
Under the conditions of bad working environments, reduce interior media whirlpool power, it is existing by increase in cage bottom centrum strong bottom by
Vortes interference, but also need further improvement.
The content of the invention
The purpose of the present invention is that there is provided a kind of combined magnetic force pump cage for existing issue.
The present invention is achieved by the following technical solutions：On a kind of combined magnetic force pump cage, including cover body, cover body
Provided with edge is installed, the cover body bottom centre position, which is provided with column type dead slot, column type dead slot, is provided with internal thread；It is equal outside column type dead slot
Center at the top of the even multiple spiral salients smoothly reduced by center to outside height of distribution, the spiral salient is provided with spiral shell
Rotary stall bar；
Also include below choked flow hollow ball, choked flow hollow ball being column type connecting portion, column type connecting portion outer end is provided with and internal thread phase
The external screw thread of matching；It is to be uniformly circumferentially distributed manhole in hollow hemisphere, hollow hemisphere above choked flow hollow ball.
As further improvement of these options, the width of the spiral salient by the export-oriented cover body outer wall of column type dead slot by
It is decrescence small.
As further improvement of these options, the diameter of manhole is by away from cover body bottom in the hollow hemisphere
Portion is gradually reduced to close to cover body bottom.
As further improvement of these options, without manhole at the top of the hollow hemisphere.
As further improvement of these options, the quantity of the spiral salient is 3-8.
It is used as further improvement of these options, a diameter of 1-4mm of the manhole.
As further improvement of these options, the distance between manhole in same level height is more than the water
The diameter of flat height manhole.
As further improvement of these options, the choked flow hollow ball is noted by polyether-ether-ketone and PVC plastic for raw material
It is moulding into.
As further improvement of these options, the addition in the polyether-ether-ketone injection raw material is than being its gross weight
18-24%。
The present invention has advantages below compared with prior art：Choked flow hollow ball is set in cover body bottom in the present invention, can
Effectively prevent occurring whirlpool power in cage, the manhole on choked flow hollow ball can effectively divide interior media from all directions
In the choked flow hollow ball of stream, impulsive force is greatly reduced, outside spiral shape projection will be further introduced into choked flow hollow ball
The whirlpool power of interior media is effectively decomposed in medium shunt, multiple action, and the invention is used and easily the isolation of whirlpool power occurs
In cover, run 18 months, do not occur due to the adverse consequences that whirlpool power is produced, operating index stability is good, at runtime compared with
It is long, because dielectric corrosion effect causes to damage to choked flow hollow ball, change choked flow hollow ball.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of choked flow hollow ball.
Fig. 3 is the top view of the present invention.
Fig. 4 is the stereogram of cage bottom.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figs. 1-4, a kind of combined magnetic force pump cage, including cover body 1, cover body 1, which is provided with, to be installed along 2, institute
The bottom centre position of cover body 1 is stated provided with column type dead slot 3, column type dead slot 3 is interior to be provided with internal thread 31；It is uniformly distributed outside column type dead slot 3
Multiple spiral salients 4 smoothly reduced by center to outside height, the center at the top of spiral salient 4 is provided with spiral shelves
Bar 41；
Also include choked flow hollow ball 5, the lower section of choked flow hollow ball 5 is column type connecting portion 52, the outer end of column type connecting portion 52 be provided with it is interior
The external screw thread 521 that screw thread 31 matches；The top of choked flow hollow ball 5 is uniform by circle in hollow hemisphere 51, hollow hemisphere 51
Week distribution manhole 511.
As further improvement of these options, the width of the spiral salient 4 is by the export-oriented cover body outer wall of column type dead slot 3
It is gradually reduced；In the hollow hemisphere 51 diameter of manhole 511 from away from cover body bottom to close to cover body bottom gradually
Reduce；Without manhole 511 at the top of the hollow hemisphere.
Wherein, the quantity of the spiral salient 4 is 7；A diameter of 1-4mm of the manhole 511.
As further improvement of these options, the distance between manhole 511 in same level height is more than
The diameter of the level height manhole 511；
The choked flow hollow ball 5 is molded for raw material by polyether-ether-ketone and PVC plastic and formed；In the polyether-ether-ketone injection raw material
Addition is than the 18-24% for its gross weight.
The form structure of interior media whirlpool power, this hair can be decomposed by being drawn by numerical computations and repetition test repeatedly
Choked flow hollow ball 5 is set in cover body bottom in bright, can effectively prevent occurring in cage on whirlpool power, choked flow hollow ball 5
Manhole 511 can greatly reduce impulsive force by interior media out of all directions are effectively shunted choked flow hollow ball 5, outside
The medium shunt that will further be introduced into choked flow hollow ball 5 of spiral shape projection 4, multiple action effectively decomposes interior media
Whirlpool power, the invention is used in the cage for whirlpool power easily occur, run 18 months, is not occurred because whirlpool power is produced
Adverse consequences, operating index stability is good, longer at runtime, because dielectric corrosion effect causes to damage to choked flow hollow ball
It is bad, choked flow hollow ball is changed, it is easy to use, it is easy to promote.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
