Description

Technical Field

[0001] The invention relates to the field of speed regulators, and in particular to a method for using a permanent magnet speed regulator. Background Art

[0002] In large-scale mining, petrochemical, electric power, metallurgy and other industries, permanent magnet speed control devices are increasingly used due to the need for energy conservation and environmental protection.

[0003] The permanent magnet speed regulation device can adapt to various harsh environments, including places with large grid voltage fluctuations, severe harmonics, flammable and explosive, humid, dusty and other places. It can adjust the speed of the load online to meet the actual operation needs of the system and achieve speed regulation and energy saving. The speed regulation range is 0-98%, and the energy saving rate is 10% to 65%.

[0004] During operation, the motor drives the conductor rotor component of the permanent magnet speed regulator to rotate. The copper conductor on the conductor rotor component cuts the magnetic flux lines emitted by the permanent magnet on the permanent magnet rotor component to generate eddy currents. The eddy currents generate an induced magnetic field. The induced magnetic field couples with the source magnetic field of the permanent magnet to generate torque, so that the permanent magnet rotor component drives the load to rotate.

[0005] Because permanent magnet speed regulation technology is simple and reliable, the equipment has a long service life and there is no electromagnetic wave interference problem; therefore, speed regulation devices in many places with difficult conditions are gradually being replaced by permanent magnet speed regulators.

In addition, the guide pin 22 of the present invention is plugged into the output connection disk 21, so that the output connection disk 21 can move laterally on the guide pin 22, thereby avoiding interference problems when the driving part adjusts the output connection disk 21; in addition, in the present invention, a plurality of guide parts are provided, and the guide parts are spaced apart at the end of the output shaft 25, and the guide pin 22 in the guide part is plugged into the output connection disk 21. In the present invention, the mutual cooperation between the guide parts can well realize the position limitation of the output connection disk 21, and the guide pin 22 in the guide part has a good guiding function in addition to the above-mentioned limiting function, thereby ensuring the linearity of the output connection disk 21.

[0039] In addition, in the present invention, the guide pin 22 is arranged at the end of the output shaft 25 through the connecting block 221. The connecting block 221 plays a basic connecting role, which facilitates the arrangement of the guide pin 22 on the output shaft 25.

In the present invention, the connection method between the guide pin 22 and the connecting block 221 can be a threaded connection or other connection methods.

[0040] The end of the guide pin 22 has a protrusion, and the protrusion at the end of the guide pin is connected to the connecting block 221 through a screw; such a configuration can ensure the stability of the installation of the guide pin.

In actual arrangement, the front oil path 25b and the rear oil path 25a cannot be connected to each other, so in the present invention, the front oil path 25b and the rear oil path 25a are distributed at intervals. In addition, in the present invention, the number of the front oil path 25b and the rear oil path 25a is selected according to needs, and multiple paths can be set. Such an arrangement can reduce the problem that the adjustment mechanism cannot be used due to the blockage of a certain oil path.

[0044] Furthermore, in the present invention, the piston rod 28 includes a base block 281, on which a plug-in rod 282 is provided, and the outer diameter of the base block 281 is larger than the outer diameter of the plug-in rod 282; the base block 281 is connected to the output connecting disk 21 through the plug-in rod 282; in the present invention, the base block 281 plays a basic connection role, and also plays a spacing and separation role, which is convenient for cooperating with the front oil supply mechanism and the rear oil supply mechanism to realize the pushing of the piston rod 28, and the plug-in rod 282 plays a bridging role, which is convenient for the piston rod 28 to pass through the end cover 29 and connect with the output connecting disk 21.

[0047] Furthermore, in the present invention, a spacer 26 is provided on the output shaft 25; the spacer 26 is sleeved on the output shaft 25; an oil inlet ring groove 261 is provided on the spacer 26; the front oil circuit 25b and the rear oil circuit 25a correspond to an oil inlet ring groove 261 respectively; the oil inlet ring groove 261 is connected to the front oil circuit 25b or the rear oil circuit 25a; the spacer 26 is sleeved on the output shaft 25; the setting of the spacer 26 can facilitate the external connection of the front oil circuit 25b and the rear oil circuit 25a on the output shaft 25, and at the same time, the setting of the oil inlet ring groove 261 on the spacer 26 facilitates the supply of oil in subsequent use. In the present invention, the oil inlet ring groove 261 is distributed in an annular manner on the spacer 26 and runs through the spacer 26. 261 is often connected with the oil supply path on the bearing seat 23. Based on such a configuration, even when the spacer ring 26 rotates synchronously with the output shaft 25, the oil supply and return operations can be realized as needed, thereby conveniently limiting the position of the piston rod 28. In other words, the present invention can ensure the smooth progress of the oil supply operation and reduce the difficulty of oil supply through the configuration of the spacer ring 26. In addition, in the present invention, the spacer ring 26 and the output shaft 25 are an integrated structure. Of course, the spacer ring 26 can also be external. However, when the spacer ring 26 is external, the spacer ring 26 and the output shaft 25 are connected by interference fit, and it is required that there should be no gap at the connection between the spacer ring 26 and the output shaft 25. Such a configuration can avoid oil overflow.

[0048] Furthermore, in the present invention, a bearing mechanism is also provided on the output shaft 25. The setting of the bearing mechanism facilitates the arrangement of an external oil supply mechanism and facilitates the subsequent oil supply operation in the oil tank 210. Specifically, in the present invention, the bearing mechanism includes a bearing seat 23. The bearing seat 23 is equivalent to the output shaft 25 and does not rotate. In order to avoid interference, in the present invention, the bearing seat 23 is sleeved on the output shaft 25 through a support bearing 24; in this way, the setting of the bearing seat 23 can be avoided and the normal operation of the output shaft 25 can be ensured; in addition, in the present invention, an oil supply circuit is provided on the bearing seat 23; the setting of the oil supply circuit facilitates the supply of oil in subsequent use, and at the same time, through the setting of the oil supply circuit, it is convenient to connect with an external oil supply device or oil supply mechanism, and facilitates the subsequent oil supply operation to the oil tank 210.

[0049] Specifically, the oil supply circuit in the present invention includes a plurality of regulating oil circuits 23a, each regulating oil circuit 23a corresponds to an oil inlet ring groove 261 on the spacer 26; the plurality of regulating oil circuits 23a are spaced apart and are not connected to each other, so as to avoid mutual influence between the front oil supply mechanism and the rear oil supply mechanism. In addition, in order to ensure the normal oil supply in the oil groove 210, the present invention requires that at least two regulating oil circuits are provided, and one regulating oil circuit corresponds to an oil inlet ring groove 261; specifically, the regulating oil circuit 23a is arranged through the bearing seat 23; adjacent regulating oil circuits 23a are spaced apart; the front oil circuit 25b corresponds to at least one regulating oil circuit 23a through the oil inlet ring groove 261 on the spacer 26; the rear oil circuit 25a corresponds to at least one regulating oil circuit 23a through the oil inlet ring groove 261 on the spacer 26; such an arrangement can well ensure that the front oil supply mechanism and the rear oil supply mechanism do not interfere with each other, and can be controlled as needed in actual use, so as to conveniently achieve the purpose of the present invention.

[0050] Furthermore, in the present invention, a sealing portion is provided between the bearing seat 23 and the spacer ring 26; the sealing portion includes a sealing ring 27 arranged at the connection between the bearing seat 23 and the spacer ring 26; the setting of the sealing ring 27 plays a good sealing role to prevent oil from leaking from between the bearing seat 23 and the spacer ring 26. In addition, in the present invention, an oil through hole 2721 is provided on the sealing ring 27; the regulating oil circuit 23a is connected with the corresponding oil inlet ring groove 261 through the oil through hole 2721 on the sealing ring 27; the setting of the oil through hole 2721 facilitates the oil to enter the oil inlet ring groove 261 from the regulating oil circuit, and finally enter the corresponding front oil circuit 25b or the rear oil circuit 25a; the supply of oil is realized, and when the oil needs to flow back, the oil runs in the opposite direction.

[0051] Furthermore, in the present invention, a placement groove 271 is provided on the bearing seat 23, and the sealing ring 27 is placed inside the placement groove 271; the setting of the placement groove 271 facilitates the arrangement and installation of the sealing ring 27 on the bearing seat 23. In addition, in the present invention, it is required that the width of the placement groove 271 is greater than the width of the oil inlet ring groove 261; at the same time, it is also required that the size of the sealing ring 27 is greater than the size of the oil inlet ring groove 261. Based on such a structural design, the setting of the lead sealing ring 27 between the bearing seat 23 and the spacer ring 26 forms a liquid storage space, which facilitates the subsequent supply and return of oil, and also plays a buffering role to avoid excessive impact caused by excessive running speed of the oil circuit.

[0052] Furthermore, in the present invention, the sealing ring 27 includes a base plate 272, and a connecting side plate 273 is respectively provided at both ends of the base plate 272, and an oil through hole 2721 is provided on the base plate 272; such a configuration enables the base plate 272 and the connecting side plate 273 to form a C-shaped structure, so that the sealing ring 27 not only realizes the sealing effect, but also plays a function of storing oil, so as to better achieve the above-mentioned technical effect. In addition, in the present invention, the sealing ring 27 is an annular structure, and an inner cavity structure is formed inside because of the design of the above-mentioned structure.

[0054] specific;

[0055] The present invention discloses a method for using a permanent magnet speed regulator; the method mainly comprises a conductor rotor component 1 and a permanent magnet rotor component 2, wherein the conductor rotor component 1 is mounted on a motor through a motor flange 12, and a permanent magnet disk component (output connecting disk 21) of the permanent magnet rotor component 2 is mounted on an output shaft 25 through a guide pin 22, and the output connecting disk 21 can slide along the guide pin 22, a piston rod 28 is mounted at the center of the output connecting disk 21, and an adjusting mechanism is arranged at the end of the output shaft 25; the sliding of the output connecting disk 21 is achieved by controlling the oil inlet direction of the adjusting mechanism, thereby changing the size of the air gap 3 and achieving the speed regulation function; the present invention discloses a permanent magnet speed regulator that uses hydraulic pressure to adjust the air gap 3, which has a compact structure, a simple mechanism, and accurate and convenient control compared to the existing permanent magnet speed regulator.

[0056] When oil flows into the front oil passage 25b on the output shaft 25, oil flows into the left side of the oil groove 210, pushing the piston rod 28 to move rightward, driving the output connecting plate 21 to move rightward, and the air gap 3 becomes larger; when oil flows into the rear oil hole on the output shaft 25, oil flows into the right side of the oil groove 210, pushing the piston rod 28 to move leftward, driving the output connecting plate 21 to move leftward, and the air gap 3 becomes smaller.

[0058] When the speed regulator is used, the method of use includes the following steps:

[0059] Step 1: Assemble the above permanent magnet speed regulator and ensure that the permanent magnet speed regulator can be used normally;

[0060] Step 2: Determine the air gap change requirement in the permanent magnet speed regulator;

[0061] When the air gap in the permanent magnet speed regulator needs to be increased, oil is supplied to the front end of the oil tank through the front oil supply mechanism, and the oil entering the oil tank pushes the piston rod to move toward the bottom of the oil tank, thereby driving the output connection disk to move toward the end away from the input connection disk, thereby increasing the air gap in the permanent magnet speed regulator;

[0062] When the air gap in the permanent magnet speed regulator needs to be reduced, oil is supplied to the rear end of the oil tank through the rear oil supply mechanism, and the oil entering the oil tank pushes the piston rod to move away from the bottom of the oil tank, thereby driving the output connection disk to move toward the end close to the input connection disk, thereby reducing the air gap in the permanent magnet speed regulator;

[0063] Step 3: When the air gap change in the permanent magnet speed regulator reaches the set requirement, the front oil supply mechanism and the rear oil supply mechanism are required to be in a pressure-maintaining state before being put into use.

[0064] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
