Description
(1) technical field under
The utility model relates to a kind of pulsating fluid pipeline shock absorber bracket, and it belongs to vibration damping weakening, the reduction of industrial process piping or eliminates the support device of pipe stress damage.
(2) background technique
Piping vibration can cause that pipeline is connected the fatigue ruption of machinery with support even its, influences the proper functioning of instrument and apparatus.The root that causes vibration varies, but sees nothing more than forced vibration and self-excited vibration from the angle of power after all.Forced vibration is the system vibration response that the power by the external world causes, the bigger vibration of general extraneous power is stronger.In the pipe-line system of reciprocating compressor, reciprocating pump, centrifugal compressor, centrifugal pump, the pulsating force of pulsating fluid is all roots that cause vibrations such as pump, piping.For this reason, cut down or eliminate pulsating force, absorb the energy that transforms pulsating force and be one of effective way of pulsating fluid pipeline vibration damping.
Domestic present shock absorber bracket main structure form roughly is divided into two classes, and do not have specially the product at the pulsating force vibration damping: a class is the fixed bracket of forming with shaped steel, wooden unit, and another kind of is elastic support based on common helical spring.The fixed bracket that shaped steel, wooden unit are formed, it utilizes the micro-elastic displacement vibration damping of wooden unit, this can play certain effect in general vibrating conduit, but this structure can not be applied to the occasion of higher temperature, simultaneously can not compensate the piping thermal walking, so effectiveness in vibration suppression is not obvious, application is very limited.Common elastic support reduces the periodic vibration or the transient impact power of general piping by helical spring initial pretightening force, be applicable to outside external force (as wind-force, seismic force) the exciting occasion of pipeline, it can't adapt to has the pipe interior fluid to be pulse state to flow, i.e. the demanding occasions of vibration damping vibrationproof such as periodic vibration fluid line of high fluctuation pressure.
(3) summary of the invention
The purpose of this utility model is exactly in order to overcome the defective of above-mentioned prior art, a kind of demanding pulsating fluid pipeline of vibration damping vibrationproof shock absorber bracket that has fluctuation pressure to exist is provided, it can provide pipeline adjustable axial force constraint, reduce or eliminate voluntarily the thermal stress of piping, make the vibration damping vibrationproof of piping be in the optimum state in allowed limits.
