Description

Oil cooling cylinder type permanent magnet speed regulator

Technical Field

The invention relates to the field of permanent magnet speed regulators, in particular to an oil cooling cylinder type permanent magnet speed regulator.

Background

In the industries of large-scale mining, petrochemical industry, electric power, metallurgy and the like, the permanent magnet speed regulation device is more and more widely applied due to the requirements of energy conservation and environmental protection.

The permanent magnet speed regulating device can adapt to various severe environments including places with large voltage fluctuation of a power grid, serious harmonic waves, flammability, explosiveness, moisture, dust and the like, can regulate the rotating speed of a load on line so as to meet the actual operation requirement of a system, and realizes speed regulation and energy conservation, wherein the speed regulation range is 0-98%, and the energy conservation rate is 10-65%.

When the permanent magnet speed regulator works, the motor drives the conductor rotor part of the permanent magnet speed regulator to rotate, the copper conductor on the conductor rotor part cuts the magnetic induction lines emitted by the permanent magnets on the permanent magnet rotor part to generate eddy currents, the eddy currents generate an induction magnetic field, and the induction magnetic field and the source magnetic field of the permanent magnets are coupled to generate torque, so that the permanent magnet rotor part drives the load to rotate.

Because the permanent magnet speed regulation technology is simple and reliable, the service life of the equipment is long, and the problem of electromagnetic wave interference does not exist; so that the speed control devices in many places with difficult conditions are gradually replaced by permanent magnet speed controllers.

Therefore, the application of the permanent magnet speed regulator at the present stage is very wide, but the use of the current permanent magnet speed regulator has some defects, and when the speed regulation is in operation, the conductor cylinder generates heat due to the cutting of magnetic lines of force and the generation of eddy current, so that the conductor cylinder needs to be cooled;

The speed regulation principle of the cylindrical permanent magnet speed regulator is as follows:

the conductor rotor component 1 is driven by the motor to rotate at a constant rotating speed, when the permanent magnet rotor component 3 is positioned at the rightmost side, the projection area between the conductor cylinder 104 and the permanent magnet 308 is the smallest, namely the effect of cutting magnetic lines of force is the weakest, and at the moment, the rotating speed of the permanent magnet rotor component 3 is the lowest; when the permanent magnet rotor component 3 is at the leftmost side, the projected area of the conductor cylinder 104 and the permanent magnet 308 is the largest, that is, the effect of cutting magnetic lines of force is the strongest, and at this time, the rotating speed of the permanent magnet rotor component 3 is the highest; under the action of the speed adjusting sleeve 303, the permanent magnet rotor component 3 can be positioned at any position of maximum, minimum and middle, that is, the projected area of the conductor barrel 104 and the permanent magnet 308 can be changed between maximum and minimum, so that the rotating speed of the permanent magnet rotor component 3 can be changed.

The cooling principle is as follows:

when the speed-regulating operation is performed, the conductor cylinder 104 generates heat due to the fact that eddy current is generated by cutting magnetic lines, and the heat needs to be taken away by cooling.

The cooling oil disclosed by the invention is conveyed to the oil inlet pipe 203 through an external oil pump, is sprayed to the oil inlet groove 103a of the input connecting disc 103 from the outlet of the oil inlet pipe 203, the input connecting disc 103 is radially provided with a plurality of oil inlet holes 103b, and is communicated with the cooling oil groove 105a formed in the outer surface of the steel cylinder 105, under the action of centrifugal force generated by rotation of the conductor rotor part 1, the cooling oil enters the cooling oil groove 105a through the oil inlet holes 103b at high speed, flows through the inner surface of the conductor cylinder 104 at high speed, efficiently takes away heat, is discharged from the right end surface of the steel cylinder 105, and is discharged to the box body 2-1 through a plurality of oil outlet holes 306a of the output connecting disc 306 of the permanent magnet rotor part 3.

The invention is different from the traditional permanent magnet speed regulator in that the traditional cylindrical permanent magnet speed regulator generally adopts water liquid to carry out cooling operation, namely a nozzle is arranged in a box body 2-1 to directly spray water on the surface of a conductor to take away heat, and grease is adopted for lubricating a bearing.

The traditional bearing has poor lubricating and cooling effects, the sealing requirement of the bearing and the space in the box body 2-1 is high, water or vapor cannot be avoided, the aging and the degradation of lubricating grease are accelerated, and the service life of the bearing is shortened to a certain extent; in addition, the surface spray cooling is used traditionally, the cooling effect is poor, the power loss is large, the corrosion of water to metal parts is serious, and the service life of the product can be shortened to a certain extent; the oil liquid is adopted to cool and lubricate the speed regulator, so that the problems are well solved.

Meanwhile, the traditional speed regulator is also cooled by oil, but the traditional speed regulator is essentially different from the traditional speed regulator in that the oil is used for cooling, the oil of the invention passes through the inside of the component, the cooling effect is optimized, and the problem of poor surface spraying cooling effect is well avoided.

It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
