Abstract

A fluid speed regulating cylinder type magnetic coupler can be classified into the fields of power transmission, energy-saving and emission reduction, rotary equipment and magnetic driving. The purposes of speed regulation and energy saving are achieved by combining a hydraulic cylinder or air cylinder with a fluid speed regulating high-speed rotary joint and adjusting the area of magnetic coupling through piston extension and retraction. The invention provides an economical and feasible method for speed regulation and energy saving of rotary equipment.

Description

Fluid speed governing cartridge type magnetic coupling
Technical field
Power transmission, energy-saving and emission-reduction, moving equipment, magnetic drive.
Background technology
From human use's earth magnetism drives invention compass, the utilization of magnetic field energy research just never stopped.Be accompanied by the development of modern theory of magnetism, the application of magnetic drive product in industry 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, high performance permanent magnetic materials neodymium iron boron has been invented by China, magnetic drive product is just rapidly developed application.
Since magnetic drive pump isodynamic drives the independent branch's development of independent conduct product, there is panoramic product in magnetic coupling.Cartridge type magnetic coupling is as one type in Ci Ou family, because of the reason of its configuration aspects, slightly inferior at aspects such as safety in utilization, reliabilities, but in some local fields, cartridge type magnetic coupling is also a kind of good transmission device, has its distinctive feature.
Energy-saving and emission-reduction are current active demands, generally apply at present fluid-flywheel clutch and carry out power transmission, and the relative magnetic coupling of transmission efficiency is lower.Although frequency control is more or less the same with magnetic coupling on speed efficiency, compare greatly differ from each other with magnetic coupling with maintainability the useful life of frequency converter.
Summary of the invention
The present invention focuses on the technical method that finds the speed governing of a kind of cartridge type magnetic coupling---fluid (hydraulic pressure or pneumatic) speed governing.
Accompanying drawing explanation
Fig. 1 is fluid speed governing cartridge type magnetic coupling, can adopt Hydraulic Adjustable Speed or pneumatic speed governing, and because gas has very large compressibility, pneumatic speed governing can be used for not too accurate occasion, and hydraulic pressure can be used for accurate speed governing.
In Fig. 1, label 2 is induction cylinder, and label 4 is magnetic patch, and label 17 is shielding cylinder, and label 16 is piston, and label 11 is transmission cylinder body, and label 12 is postive stop baffle, and label 7 and 19 is axle sleeve, and label 6 is high speed rotary joint, and label 3 is left cover, and label 5 is right cover plate.3, the internal rotor of 4,5,17,16,11,12,7 composition fluid speed governing cartridge type magnetic couplings, together synchronous rotary.1, the external rotor of 2,19 composition fluid speed governing cartridge type magnetic couplings.Inner and outer Rotator does not contact mutually, relies on permanent magnetic field and the interaction between the two of the upper induced field producing of induction cylinder that magnetic patch produces to transmit motion.During speed governing, by the flexible size of controlling the upper induced field producing of induction cylinder of piston, thus the size of change transmitted power.During speed governing, the magnetic patch being exposed to outside induction cylinder will cause electromagnetic hazard, and has potential safety hazard.After installing protective cover additional, should control the distance of protective cover and internal rotor well, hypotelorism, is equivalent to install additional a forced brake device, causes energy loss.In addition, magnetic patch fragility is large, frangible, so protected working must be carried out.Axle sleeve 7 and 19 and the connection of axle adopt expansion set.
Fig. 2 has clearly expressed the fixing mode of magnetic patch, and wedge clamps.The effect of power transmission shaft of having held concurrently of transmission cylinder body, its exterior contour is high-visible from scheming.
Fig. 3 has clearly expressed the runner situation of internal rotor ventilation and heat, can on external rotor, install guide vane additional according to rotor rotation direction, causes powerful forced ventilation heat radiation.
Fig. 4, Figure 5 shows that high speed rotary joint, adopt modular series connection structure, any passage of can connecting, shown in Fig. 4, be two passages, sealing ring 6-19,6-20 can select with materials such as tungsten carbides, graphite according to the situation of working fluid, and 6-5 is spring, are used for balance contact, the guide finger 6-7 at spring place plays guide and limit effect to spring, and while preventing high speed rotary, spring lost efficacy under centrifugal action.High speed rotary joint Ke You specialized factory produces supporting, and GT assembling, is fixed on center driving axle by holding screw.
Figure 6 shows that fluid speed governing cartridge type magnetic coupling installs the organization plan of synchronous shielding cylinder additional, number in the figure 24 is synchronous shielding cylinder, can effectively prevent leakage field harm, and increase the fail safe of equipment, solve the defect existing in the cartridge type of fluid speed governing shown in Fig. 1 magnetic coupling structure.
Embodiment
Fluid speed governing cartridge type magnetic coupling comprises respectively forms parts, and modern industry manufacturing technology all can processing and manufacturing.Magnetic patch, high speed rotary joint, hydraulic cylinder and cylinder etc. all can be formed a complete production network by specialized vendor, other parts machine work, welding, die forming.
Fluid speed governing cartridge type magnetic coupling is as a kind of moving equipment, its finished product wants successful Application, must possess following two conditions: (1) power calibration---set up complete testboard bay (each power moment of torsion is interval), to complete the demarcation of tandem product.(2) dynamic balancing detects---and slewing must reach the requirement for dynamic balance of correlation standard, to reach necessary security reliability.
