The features of the invention believed to be novel are set forth with particularity in the appended claims. The invention itself however may be best understood by reference to the following detailed description of the invention, which describes certain exemplary embodiments of the invention, taken in conjunction with the accompanying drawings in which:
The technical characteristics, features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings. However, the drawings are provided for reference and illustration only and are not intended for limiting the scope of the invention.
Referring to
The pipe 10 is a circular vertical pipe having an opening 11, 12 disposed separately on both upper and lower ends of the pipe 10, and an internal screw thread 13 disposed on an internal surface of each opening 11, 12.
The connecting base 20 is connected separately to each opening 11, 12 of the pipe 10 and includes a joint 21, an extending ring 22 protruded downward from the bottom of the joint 21, and an external screw thread 221 disposed at the external periphery of the extending ring 22 for connecting the internal screw thread 13 of the pipe 10. The extending ring 22 forms a shaft base 23 therein, and the shaft base 23 is connected to an internal wall of the extending ring 22 by a plurality of support arms 24, and a through groove 25 is formed between the support arms 24. Further, a flange 26 is protruded outward from a position between the joint 21 and the extending ring 22 for attaching distal surfaces of each opening 11, 12 of the pipe 10.
The rotor 30 is disposed in the pipe 10 and parallel to the axis of the pipe 10. The rotor 30 includes a revolver 31 and a magnet element 32, and the revolver 31 can be made of a plastic material or a ceramic material and installed according to the properties of different fluids. The revolver 31 has a protruding shaft 311 protruded separately from both ends of the revolver 31 and embedded correspondingly in the shaft base 23 of the connecting base 20. The revolver 31 at its exterior forms a plurality of spiral vanes 312 for boosting the pressure of the fluid, and the magnet element 32 can be a circular or cylindrical permanent magnet (not shown in the figure). In this embodiment, the magnet element 32 is comprised of a cylinder 321 and a plurality of magnetic pole plates 322 disposed with an interval apart from each other and around an external periphery of the cylinder 321.
The stator 40 is disposed around the exterior of the pipe 10 and corresponding to the rotor 30, and the stator 40 includes two silicon steel rings 41 and a coil module 42, and each silicon steel ring 41 has four arc plates 411 disposed with an interval apart from each other inside the silicon steel ring 41, and the coil module 42 is installed at an external periphery of each plate 411, and the plates 411 of each silicon steel ring 41 are installed alternately, such that when the coil module 42 is electrically conducted by a current, the interactions of magnetic excitation will drive the rotor 30 to rotate with respect to the stator 40.
Referring to
The present invention is illustrated with reference to the preferred embodiment and not intended to limit the patent scope of the present invention. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
