Description
Technical Field
The utility model relates to the technical field of magnetic pumps, in particular to an external magnetic rotor structure for a magnetic pump.
Background
In the field of domestic chemical equipment, an outer magnetic rotor in a magnetic pump is one of core components of the pump, the outer magnetic rotor and an inner magnetic rotor are matched with each other, and the inner magnetic rotor is connected with an impeller together. When the outer magnetic rotor rotates, the inner magnetic rotor is driven to rotate synchronously, so that the impeller is driven to rotate together to convey media such as liquid. The commonly used outer magnetic rotor mainly comprises magnetic blocks and outer magnetic steel, and the magnetic blocks are usually fixed one by directly adopting glue to be bonded in the outer magnetic steel. On one hand, the fixing mode is not easy to control and not safe enough in the process of installing the magnetic block by an operator because the external magnetic steel is larger than the magnetic block and has an irregular shape; on the other hand, the magnetic blocks are directly bonded by glue, the requirement on the bonding surface is high, the pump runs at a high speed for a long time, the risk of magnet falling is high, and once the magnet falls, other internal structural components of the pump are damaged to cause leakage.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an outer magnetic rotor structure for a magnetic pump, which aims to solve the problems of inconvenience in installation, unsafety in installation and easiness in falling off of a magnetic block during operation and damage to an internal structural part caused by the fact that the magnetic block and the inner part of outer magnetic steel are fixed in a bonding mode in the prior art.
In order to achieve the purpose, the utility model provides the following technical scheme: the outer magnetic rotor structure for the magnetic pump comprises an outer magnetic ring assembly, wherein the outer magnetic ring assembly comprises an outer magnetic ring and an outer magnetic block, the outer magnetic ring is annular, a plurality of mounting grooves are formed in the inner wall of the outer magnetic ring, and the outer magnetic block is embedded into the mounting grooves and fixed through fastening screws.
Preferably, the mounting groove is in a dovetail groove shape, and the width of the groove bottom of the mounting groove is larger than that of the groove opening of the mounting groove.
Preferably, the bottom of each mounting groove is provided with a through hole, the outer magnetic block is provided with a threaded hole corresponding to the through hole, and the fastening screw is screwed into the threaded hole of the outer magnetic block from the periphery of the outer magnetic ring.
Preferably, the outer magnetic coil assembly is tightly matched and fixed with the outer magnetic steel.
Compared with the prior art, the utility model has the beneficial effects that: a plurality of mounting grooves are formed in the outer magnetic ring, then the outer magnetic block is embedded into the mounting grooves and fixed through fastening screws, the outer magnetic block is not easy to fall off, the operation is safer, the process of mounting the outer magnetic block is convenient and easy to control, and the convenience and the safety of continuously mounting the plurality of magnetic blocks are improved; the mounting groove is in a dovetail groove shape, so that the accuracy of the mounting position of the outer magnetic block is ensured, and the play and the displacement are prevented from occurring in the mounting process of the plurality of magnetic blocks.

In the figure: 1 external magnetic steel, 2 external magnetic coils, 3 external magnetic blocks and 4 fastening screws.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides an outer magnetic rotor structure for magnetic pump, including outer magnetic ring subassembly, outer magnetic ring subassembly includes outer magnetic ring 2 and outer magnetic piece 3, outer magnetic ring 2 is the ring form, a plurality of mounting grooves are seted up to 2 inner walls of outer magnetic ring, it is fixed in 3 embedding mounting grooves of outer magnetic piece and through fastening screw 4, it is specific, the through-hole has all been seted up to every mounting groove bottom, set up the screw hole that corresponds with the through-hole on the outer magnetic piece 3, fastening screw 4 twists in the screw hole of outer magnetic piece 3 from the periphery of outer magnetic ring 2, outer magnetic piece 3 also is difficult for droing like this, it is safer to move, the process of installation outer magnetic piece 3 also becomes convenient and easy control, the convenience and the security of installing a plurality of magnetic pieces in succession have been improved.
Preferably, in this embodiment, the mounting groove is dovetail groove-shaped, that is, the groove bottom width of the mounting groove is greater than the notch width of the mounting groove, and such a design can further ensure that the mounting position of the outer magnetic block 3 is accurate, and prevent the play and the displacement from occurring in the mounting process of a plurality of magnetic blocks.
During installation, an outer magnetic ring assembly is synthesized by the outer magnetic ring 2 and the outer magnetic block 3 through the fastening screw 4, and the synthesized outer magnetic ring assembly is integrally connected with the inner part of the outer magnetic steel 1 in a tight fit mode through the tooling equipment.
In this application, earlier with outer magnetic path 3 imbed in the mounting groove of outer magnetic path 2, then fix through fastening screw 4, the installation of outer magnetic path 3 is convenient easy control more and the installation is more firm, and outer magnetic path 3 is also difficult for droing, moves safelyr, has also improved the convenience and the security of installing a plurality of magnetic paths in succession.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
