Abstract

The utility model relates to a pressing cushion device for a high strength core-type reactor core. The cushion device comprises a tightening screw rod arranged between an upper iron yoke and a lower iron yoke, an iron core discus arranged on the tightening screw rod, a dish-shaped spring arranged between the iron yoke and a pressing nut, and a pressing bracing plate. The cushion device penetrates from the bottom part of a core column in the center of the iron core column to the top part thereof; the core column, the iron core discus, the iron yoke and the like are pressed into a whole body by using a plurality of cross-core pull rods; the cushion device is pressed by adopting the elasticity of the dish-shaped spring; and the electromagnetic attraction between the iron core discus is balanced through the elasticity of the dish-shaped spring, thereby achieving the dynamic force balance and effectively reducing the vibration and the noise of the reactor. Therefore, the vibration and the noise performance parameters of the reactor can greatly satisfy the requirements of user.

Description

A kind of high strength core type reactor core pressing vibration absorber

Technical field

The utility model relates to a kind of high strength core type reactor core pressing vibration absorber.

Background technology

Core type reactor stem unshakable in one's determination is formed by several cakes unshakable in one's determination and air gap cushion block closed assembly, the vibration of core type reactor body and noise are mainly derived from the vibration and the noise of the electromagnetic attraction generation that alternating flux produces between cake unshakable in one's determination, for vibration and the noise that reduces reactor, be provided with stem unshakable in one's determination effectively to compress with vibration absorber be to reduce the vibration of reactor and the key of noise, the measure of the vibration absorber of each manufacturing firm's employing and reduction noise is varied at present, its vibration absorber and noise reduction measure finally reflect by the test measurements of vibration and noise, because the measure difference of each manufacturing firm, the test measurements of vibration and noise then has bigger difference, and the vibration of some product and noise have surpassed user's required value, have produced bigger potential safety hazard for the long-time running of reactor.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of high strength core type reactor core pressing vibration absorber, can effectively reduce the vibration and the noise of reactor, prevent by the harm of vibrating and noise causes for the long-time running of reactor, guarantee the operation of reactor long-term safety.

The utility model adopts following technical scheme:

The utility model comprises the stretching screw that is arranged between lower yoke, be set in cake unshakable in one's determination on the stretching screw, be arranged on the disk spring between iron yoke and the clamp nut and compress fagging, and the bottom of described stretching screw is connected with lower yoke.

The utility model good effect is as follows: the utility model extends through the top at stem unshakable in one's determination center from the stem bottom, using many punching pull bars that each cake unshakable in one's determination of stem and iron yoke etc. are compressed is an integral body, it compresses mode for adopting the disk spring elastic compression, elastic force by disk spring comes the electromagnetic attraction between balance cake unshakable in one's determination, reach a kind of dynamic equilibrium of forces, effectively reduced the vibration and the noise of reactor, made the vibration of reactor and the requirement that the noiseproof feature parameter is better than the user greatly.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the utility model side view cutaway drawing;

In the accompanying drawings: 1 compresses fagging, 2 disk springs, 3 pipe nuts, 4 clamp nuts, 5 clamp nuts, 6 clamp nuts, 7 stretching screws, 8 iron yokes, 9 cakes unshakable in one's determination.

Embodiment

The utility model comprises the stretching screw 7 that is arranged on 8 of lower yokes, be set in cake unshakable in one's determination 9 on the stretching screw 7, be arranged on the disk spring 2 between iron yoke 8 and the clamp nut 6 and compress fagging 1, and the bottom of described stretching screw 7 is connected with lower yoke 8.

As shown in drawings, many stretching screws 7 extend through the top at stem unshakable in one's determination center from the stem bottom, and it is an integral body that each cake 9 unshakable in one's determination of stem and iron yoke 8 are compressed, and pipe nut 3 cooperates with stretching screw 7, is the clamp nut of stretching screw 7.Clamp nut 4, clamp nut 5, clamp nut 6 and disk spring 2 are combined into the elastic compression system, compress fagging 1 and play balanced power, and thrust evenly is delivered to iron yoke 8 and cake unshakable in one's determination 9.

The utility model extends through the top at stem unshakable in one's determination center from the stem bottom, using many punching stretching screws 7 that each cake 9 unshakable in one's determination of stem and iron yoke 8 are compressed is an integral body, it compresses mode for adopting disk spring 2 elastic compressions, come the electromagnetic attraction of 9 of balance cakes unshakable in one's determination by the elastic force of disk spring 2, reach a kind of dynamic equilibrium of forces, effectively reduced the vibration and the noise of reactor, made the vibration of reactor and the requirement that the noiseproof feature parameter is better than the user greatly.
