Description
Technical field
The present invention relates to a kind of rotor online automatic balancing device of high-speed rotating machine.
Background technology
Along with the develop rapidly of science and technology, modern mechanical develops to high speed, high-level efficiency, high precision direction, limits and the vibration that reduces various machineries is promptly carried out transient equilibrium and seemed more and more important.Dynamically balanced gordian technique is the design of dynamic balance execution device.At present, the dynamic balance execution device of widespread use can be divided into following three classes:
1, direct-on-line dynamic balance execution device: set about from the quality aspect, by increasing the weight of weight, directly the geometric center with the balance disk moves on to rotation center, has spraying process, liquid ejecting method and laser to go heavy method etc.
2, indirect on-line dynamic balancing actuating unit: opposite with the out-of-balance force direction, equal-sized power is provided for a long time for disk, moves its center of gravity to rotation center by force.At present, this dynamic balance execution device mainly contains electromagnetic bearing type and electromagnetism collar plate shape.
3, mixed type on-line dynamic balancing actuating unit: during work, change dynamic balance execution device internal soundness distribution (not increasing the weight of also not go heavily) in some way, its geometric center is overlapped with rotation center, and the redistribution of quality can be undertaken by mechanical means or electromagnetic method.According to the difference of driven equilibrium mass move mode, can be divided into electronic type and electromagnetic type to control mode.When rotor produces unbalance vibration, adjust the position of balance mass piece, rotor-support-foundation system is carried out on-line dynamic balancing, after the rotor-support-foundation system balance, can cut off motor power or cancel dragging the electromagnetic force that the balance mass piece moves, saved the energy.
All there is congenital shortcoming in above-mentioned various dynamic balance execution device when being used at a high speed (rotating speed surpasses 10000r/min) rotor on-line dynamic balancing:
In the first kind direct-on-line dynamic balance execution device, it is the method for adjustment that can't restore that laser removes heavy method and spraying process, and high speed is adjusted, and precision is low, optional equipment (thermal spraying apparatus or lasing light emitter equipment) is too complicated and expensive, can't really promote in industrial applications.Liquid ejecting method has certain application in industrial occasions now, but when the rotor high-speed of rotating machinery rotates, can reduce greatly owing to vaporizing liquid, injection time-delay cause the adjustment precision.And the leakage during hydrojet is inevitably, can cause equipment pollution, and this is flagrant in most of industrial occasions.So there is practical problems in the balance method of these several direct-on-line dynamic balance execution devices, range of application is narrow.
Also there is wretched insufficiency in the indirect on-line dynamic balancing actuating unit of second class, and promptly rotor is subjected to the effect of balance electromagnetic force always in operational process, and energy consumption is big, and the physical construction internal stress is big.And when rotating speed was too high, can distort in magnetic field increased greatly from the control that makes the balance electromagnetic force is non-linear, can't realize accurate control.
Motor-type can't be used for high-speed rotating machine owing to this body structure and mounting means reason in the 3rd class mixed type on-line dynamic balancing actuating unit.Though electromagnetic type can be used for high-speed rotating machine, also there are two congenital wretched insufficiencies, the minimum that the adjustment dish of first electromagnetic type is axially adjusted is adjusted angle excessive (＞5 °) and is caused that to adjust ratio of precision lower, can't realize that transient equilibrium accurately adjusts.It two is that the adjustment dish of electromagnetic type can't need to lock by the electromagnetic clutch dish under non-adjustment state from locking, in case electromagnetic clutch dish fast state takes place down to lose efficacy will cause the release of adjustment dish and serious security incident takes place.
In a word, at present all there are various deficiencies in commercially available various on-line dynamic balancing actuating units and adapt to the rotor on-line dynamic balancing working environment of high-speed rotating machine fully.
