Detailed Description
The present invention will be more clearly and completely described below by way of examples and with reference to the accompanying drawings, but the present invention is not limited thereto.
As shown in fig. 1, the water pump impeller retarding driving device according to the embodiment of the present invention includes a driving mechanism 1, a conductive block 2, an impeller 3, and a plurality of magnets 4, wherein the plurality of magnets 4 are all connected to the impeller 3, gaps exist between the conductive block 2 and the impeller 3, and between the plurality of magnets 4, the driving mechanism 1 is connected to the conductive block 2 and is configured to drive the conductive block 2 to rotate, so that the conductive block 2 cuts magnetic induction lines of the plurality of magnets 4.
The conductive block 2, the impeller 3 and the magnets 4 are not in contact with each other, and the driving mechanism 1 cannot directly drive acting force on the impeller 3. Water pump impeller slow speed drive arrangement is when using, actuating mechanism 1 will drive conducting block 2 by slow to fast rotation, can have the magnetism line of feeling between a plurality of magnet 4, the magnetism line of feeling that will cut a plurality of magnet 4 through the rotation of conducting block 2, according to the electromagnetic induction principle, in relative stadium, conducting block 2 can give rise to magnetic field, along with the rotational speed improvement of conducting block 2, the magnetic force of conducting block 2 improves by little to big gradually, the appeal with impeller 3 improves gradually, after reaching certain starting force, starting force is greater than impeller 3's frictional resistance, make impeller 3 and a plurality of magnet 4 will drive the rotation in the lump, thereby realize the water pump operation, effectively avoided impeller 3 to start the phenomenon of skidding that causes at the excessive speed, the operating efficiency of water pump has been improved.
When the water pump impeller retarding driving device needs to stop running, after a power supply is cut off, the driving mechanism 1 does not provide driving acting force on the conductive block 2 any more, the conductive block 2 can continue to rotate due to inertia, the rotating speed is gradually reduced, the conductive block 2 cannot be stopped to rotate at once, and therefore the phenomenon that the impeller 3 is blocked or slips cannot be generated. As the speed of the conductive block 2 becomes slower, the rate of cutting the magnetic induction lines of the plurality of magnets 4 becomes smaller, and the generated magnetic field becomes smaller, so that the purpose of stably stopping the impeller 3 and the plurality of magnets 4 together is finally achieved.
In this case, the conductive block 2 is connected to the drive mechanism 1 and the magnet 4 is connected to the impeller 3, but the magnet 4 is not connected to the drive mechanism 1 and the conductive block 2 is not connected to the impeller 3. This is because the water pump impeller slow speed driving device is in the starting stage, the water pump waterway is full of water, the damping of the rotation starting of the impeller 3 is large, when the driving mechanism 1 is started, the conductive block 2 is driven to rotate, and in the process that the rotating speed is changed from small to big, the conductive block 2 cuts the magnetic induction line to generate an induced magnetic field which is also changed from small to big, at the proceeding stage of the process, the conductive block 2 needs to generate a large enough induced magnetic field to drive the magnet 4 to rotate, and the space in the water path limits the conductive block 2 to be not large, if the conductive block 2 is installed in a waterway, the space of the waterway becomes large due to the large volume of the conductive block 2, thereby increased the damping force of impeller 3, consequently, this scheme conducting block 2 connects actuating mechanism 1, and impeller 3 is connected to magnet 4, helps doing little water route damping force, increases conducting block 2 volume, reduces the starting resistance, reduces actuating mechanism 1 efficiency.
Water pump impeller slow speed drive arrangement still includes casing 5, casing 6 and baffler 7 down, and the bottom of going up casing 5 is connected in casing 6 down, and baffler 7 sets up between last casing 5 and casing 6 down, and the top surface of baffler 7 and last casing 5 are formed with first holding chamber 51, and impeller 3 and a plurality of magnet 4 all set up in first holding chamber 51, and conducting block 2 is located the below of baffler 7. Install a plurality of magnet 4 and connect on impeller 3, then set up impeller 3 and a plurality of magnet 4 in upper housing 5, barrier plate 7 is pressed and is located between upper housing 5 and lower housing 6 and connect lower housing 6 in the bottom of upper housing 5, later will connect conductive block 2 on actuating mechanism 1 and set up in the below of barrier plate 7 to accomplish the equipment. Through last casing 5 and lower casing 6 be convenient for water pump impeller slow speed drive arrangement's erection joint, simultaneously, baffler 7 has the separation effect, prevents that the water in the first holding chamber 51 will not leak outward.
Wherein, the sealing ring 52 is pressed between the blocking plate 7 and the upper shell 5, the sealing performance between the blocking plate 7 and the upper shell 5 is effectively enhanced through the sealing ring 52, and the water in the first accommodating cavity 51 is further ensured not to leak outwards.
The driving mechanism 1 is a rotating motor, the rotating motor is connected to the lower shell 6, and the conductive block 2 is connected to a rotor of the rotating motor. The rotation of the conductive block 2 is driven by the rotating motor, the structure is simple, and the assembly is convenient.
When a plurality of magnet 4 is needed to be installed on the impeller 3, the clamping piece 32 is detached and the notch of the groove is opened, the magnet 4 is placed into the groove, and then the clamping piece 32 is connected to the installation frame 31 and covers the notch of the groove, so that the magnet 4 is arranged in the second accommodating cavity. Play the limiting action to magnet 4 through second holding chamber, guaranteed that magnet 4 sets up inside impeller 3, prevent that impeller 3 from producing the obscission at the in-process magnet 4 of rotatory use, improved water pump impeller slow speed drive arrangement's stability.
