Technical field
Power transmission, energy-saving and emission-reduction, dynamic equipment, magnetic drive.
Background technology
From human use ground Magnetic driving invention compass, the research on utilization of magnetic field energy just never stopped.Along with the development of modern theory of magnetism, the application in the industry of magnetic drive product just emerges in an endless stream, magnetic drive pump, magnetic bearing, magnetic coupling, magnetic-gear etc.Be limited to the restriction of magnetic material, Drive Technology slower development, until nineteen eighty-three, Chinese invention high performance permanent magnetic materials neodymium iron boron, magnetic drive product is just rapidly developed application.
Magnetic coupling has driven product independent as since the development of independent branch from magnetic drive pump isodynamic, there is panoramic product, but be all confined to the reason of configuration aspects, can only be confined in the dynamic equipment dynamic transmission application in middle low power, medium and small moment of torsion interval, and expensive.Primary air fan (the 6000KW of picture thermal power plant, 1496r/min), secondary air fan (4550KW, 1495r/min), coal crusher (1200KW, 490r/min) and steel mill, mining site the dynamic equipment such as large fan, prior art and product all cannot meet practical application request.
Energy-saving and emission-reduction are current active demands.Dynamic device energy conservation, has variable-frequency speed-adjusting energy-saving and grooved cam mechanism speed governing magnetic coupling variable speed energy saving at present more efficiently.Frequency converter is shorter for useful life, and adaptive capacity to environment is poor, and take up an area space greatly, maintenance needs is high, and high voltage converter failure rate is then higher, poor reliability.Having carried out at present grooved cam mechanism speed governing magnetic coupling (cartridge type and disc type) that applies because of reasons in structure is of limited application, and expensive.Liquid cooling grooved cam mechanism speed governing disc electromagnetic coupling can only be applied in the dynamic equipment of below 2500KW moderate rotation reluctantly, and air-cooled grooved cam mechanism speed governing disc electromagnetic coupling can only be applied in the dynamic equipment of below 350KW moderate rotation reluctantly.Cartridge type magnetic coupling is then poorer, can only be applied in the dynamic equipment of below 800KW moderate rotation, and security reliability is not high.
LG type multi-cylinder fluid speed governing disc type magnetic coupler is the remodeling of the multi-cylinder fluid speed governing disc type magnetic coupler (domestic applications number are 201410241777.7) of previously application, installs lever lazy-tongs additional and ensures two symmetrical magnetic patch fixed disk component synchronization counter motions.
Summary of the invention
The present invention focuses on to find and a kind ofly solves the technical method that high-power, high moment of torsion moves equipment variable speed energy saving, the four large serial LG type multi-cylinder fluid speed governing disc type magnetic coupler of extending out along with this technical method---air-cooled LG type multi-cylinder fluid speed governing disc type magnetic coupler (FTLG series), liquid cooling LG type multi-cylinder fluid speed governing disc type magnetic coupler (YTLG series), air-cooled LG type multi-cylinder fluid speed governing disc type magnetic coupler of connecting (CFTLG series), series connection liquid cooling LG type multi-cylinder fluid speed governing disc type magnetic coupler (CYTLG series).
Accompanying drawing explanation
Fig. 1 is air-cooled LG type multi-cylinder fluid speed governing disc type magnetic coupler (FTLG series), and liquid cooling LG type multi-cylinder fluid speed governing disc type magnetic coupler (YTLG series), adds casing, force liquid cooling, and cooling fluid is by the pipeline turnover on shell.In Fig. 1, for making drawing clear, eliminate the projection of one group of lever lazy-tongs, and the one group of lever projection retained is not analysed and observe.
Fig. 7 is the air-cooled LG type multi-cylinder fluid speed governing disc type magnetic coupler of series connection (CFTLG series), series connection liquid cooling LG type multi-cylinder fluid speed governing disc type magnetic coupler (CYTLG series), add casing, force liquid cooling, cooling fluid is by the pipeline turnover on shell.In Fig. 7, for making drawing clear, eliminate the projection of one group of lever lazy-tongs, and the one group of lever projection retained is not analysed and observe.
Four large serial LG type multi-cylinder fluid speed governing disc type magnetic coupler, all comprise following several part: number in the figure 1 and 5 is inductive disks assembly, and 2 and 4 is magnetic patch fixed disk assembly, and 3 is multi-cylinder fluid speed adjusting gear, and 6 is high speed rotary joint.
For series connection LG type multi-cylinder fluid speed governing disc type magnetic coupler (CFTLG series, CYTLG are serial), can connect in theory any group, can determine as required, be 3 groups of series connection shown in Fig. 7, number in the figure 8 is inductive disks assembly and the magnetic patch fixed disk assembly of middle series connection.
In four large serial LG type multi-cylinder fluid speed governing disc type magnetic coupler, all inductive disks assemblies are connect by caging bolt and form external rotor, all magnetic patch fixed disk component string are associated on center driving axle, internal rotor is formed together with multi-cylinder fluid speed adjusting gear, runner is had to connect high speed rotary joint in center driving axle, the internal rotor of high speed rotary joint and center driving axle geo-stationary, the external rotor of high speed rotary joint connects external hydraulic or pneumatic circuit.Hydraulic control one-way valve or gas control unidirectional valve and electromagnetically operated valve etc. control the turnover of fluid, thus change piston move axially direction, piston rod (being fixed together with magnetic patch fixed disk assembly) drives magnetic patch fixed disk assembly centrally propeller shaft slip, thus the distance (magnetic Field Coupling gap) changed between magnetic patch fixed disk assembly and inductive disks assembly, to reach the object (change in magnetic Field Coupling gap of variable speed energy saving, the change of magnetic coupling inner and outer rotors slip will be caused, the namely change of input and output rotating speed), install lever lazy-tongs additional and ensure two symmetrical magnetic patch fixed disk component synchronization counter motions.
Figure 2 shows that A-A cutaway view.
Figure 3 shows that B-B cutaway view.
Figure 4 shows that multi-cylinder fluid speed adjusting gear, clearly illustrate the situation of runner in Fig. 2, Fig. 3, Fig. 4, because runner design can be comparatively random, compared with the mechanical governing system of complexity, fluid speed adjusting gear is relatively simple.Hydraulic Adjustable Speed can be used for accurate speed governing, and pneumatic speed governing has compressibility due to gas, can be used in the less demanding system of adjusting speed accuracy.In external hydraulic loop or pneumatic circuit, hydraulic control one-way valve or gas control unidirectional valve and electromagnetically operated valve etc. are as the switch controlling speed governing, the control of speed governing speed is then decided by the runner latus rectum of accurate Calculation, for pressurize, accumulator can be set in external circuit or integrated accumulator in center driving axle.For ensureing the synchronism of speed governing, installing lever lazy-tongs additional and ensureing two symmetrical magnetic patch fixed disk component synchronization counter motions.
Fig. 5, Figure 6 shows that high speed rotary joint, adopt modular series connection structure, can to connect any passage, be two passages shown in Fig. 5, sealing ring 6-19,6-20 can select with the material such as tungsten carbide, graphite according to the situation of working fluid, and 6-5 is spring, are used for the wearing and tearing of equilibrium contact pressure and compensation sealing ring, the guide finger 6-7 at spring place plays guide and limit effect to spring, and when preventing high speed rotary, spring lost efficacy under centrifugal action.High speed rotary joint can be produced supporting by specialized factory, GT assembles, and is fixed on center driving axle by holding screw.
The inductive disks assembly that Fig. 8 is series connection in the middle of series connection LG type fluid speed governing disc electromagnetic coupling (CFTLG series, CYTLG are serial) and magnetic patch fixed disk assembly; inductive disks assembly is positioned on the connection screw rod of magnetic coupling external rotor by positioning sleeve 8-1,8-2, and stop collar 8-5 to have slided position limitation protection effect to magnetic patch fixed disk assembly on center driving axle.
Fig. 9, Figure 10 are inductive disks assembly, card are distributed with protruding blade, to help heat radiation.During unknown device rotation direction, shape shown in Fig. 9 can be selected, as known device rotation direction, the streamline shape shown in Figure 10 can be selected, to increase heat dissipation capacity and to reduce flow-disturbing noise.Move equipment for underload, inductive disks assembly uses square position when can meet radiating requirements, shouldn't protruding blade, with simplified processing process.
Figure 11 shows that the nested scheme of elongated hole in center driving axle.About the manufacturing process of elongated hole in center driving axle, directly Small and Deep Hole Machining can be carried out.For simplified processing process, reduce manufacturing cost, aluminium extruded type also can be adopted shaping, then carry out nested method with center driving axle.
Figure 12 shows that FTLG series magnetic coupling takes off the structural representation of inner two supports bearing, connect between power transmission shaft and adopt expansion set, other series also can be done like this, but this scheme only can be used on low year situation and axle alters very small situation, reason is as follows: inductive disks assembly 1 and 5 forms external rotor by bolted on connection, magnetic patch fixed disk assembly 2 and 4 and speed adjusting gear 3, high speed rotary joint 6 connects to form internal rotor by center driving axle, inner and outer rotors is not in contact with each other, but owing to being difficult to the depth of parallelism ensureing inductive disks assembly and magnetic patch fixed disk assembly during assembling, so alternate stress (effect of magnetic Field Coupling additional bending moment) can be caused to motor center axle bearing supporting place and supporting place of load transmission axle bearing, so that axle excessive wear was lost efficacy.In addition, the impact that axle is altered can cause bumpy running, can cause the accident time serious.Generally speaking, this kind of scheme will be cautious use of.
