Problems solved by technology

[0005] Especially for some heavy-duty nuclear island safety-level equipment in nuclear power plants, such as containment circulating refrigeration units, the weight of a single nuclear-grade fan is 3 to 5 tons, and the load generated during an earthquake is 10 to 40 tons. It is difficult for the vibrator to withstand such a large load

Embodiment Construction

[0021] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0022] The present invention provides a kind of occasion that is mainly used for vibration parts and vibration equipment (such as fans and compressors) of nuclear power plants, etc., where the anti-seismic level is required. On the one hand, the present invention can realize noise reduction and vibration isolation of the vibration parts during normal operation, On the other hand, it can also be realized that the vibrating parts do not shift or fall laterally under the seismic load.

[0023] Please refer to figure 1 and figure 2 , the present invention provides a shock absorber, including: a base 1; a first block 2, which is vertically and fixedly connected with the base 1 (for example, by welding, etc.), and the first block 2 forms a lateral limiting space; a support Plate 3; the second stopper 4 is vertically a...

Abstract

The invention relates to a vibration reducer which comprises a base, a first stop block perpendicular to and fixedly connected with the base, a supporting plate, a second stop block perpendicular to and fixedly connected with the supporting plate, and an elastic part located between the base and the supporting plate. The first stop block forms a horizontal limiting space, at least one part of the second stop block is inserted into the horizontal limiting space so as to limit horizontal displacement of the supporting plate. The vibration reducer is simple in structure, convenient to install and use, capable of playing the vibration insulating effect when vibration parts conventionally operate and ensuring that the vibration parts do not perform horizontal displacement when an earthquake occurs or powerful impact force exists so as to ensure that the vibration parts and surrounding parts and devices are not damaged.

Description

technical field [0001] The invention relates to the field of vibration reduction, in particular to a vibration absorber. Background technique [0002] In many domestic industrial fields, some vibrating components or equipment (such as fans, compressors, emergency diesel engines, etc. used in nuclear power plants) are used. Displacement and dumping will affect surrounding components and equipment. [0003] In the normal state, the vibrating parts need to be damped to eliminate some noise and reduce the impact of the vibration on the surrounding objects; the vibration load at this time is relatively small, generally not exceeding 1.4 times the weight of the moving parts themselves. The shock absorber used The modulus of elasticity is also small. [0004] When an earthquake occurs, under the action of earthquake acceleration, a large load will be generated in the three directions of X, Y, and Z. According to the different degrees of earthquake cracking, the load added to the ...
