The beneficial effect of this invention are: 1) The quality of rigid-body vibration effect on the operation of equipment alternating exciting force a buffer and stabilizing role, reducing the vibration hazards; 2) Support in a number of rigid body to surface a shock absorber can be made better absorber damping effect; 3) Rectifier flow channel and rectifier plates reduce noise, reduce fluid on the channel vibration; 4) Interference can be reduced because of installing the pipeline within a deviation of stress.
Description
Technical field
The present invention relates to the vibration damping equipment in vibration control engineering field, be specifically related to a kind of vibration absorber of may command pump apparatus vibration propagation.
Background technique
Conventional isolation mounting adopts the installation framework that contains vibration isolator usually, or the supporting structure of only being made up of many vibration isolators.This isolation mounting can only hinder the transmission of vibratory equipment vibrational energy, and can not absorb or the vibrational energy of dissipates vibration equipment self.Because the vibrational energy that is installed in the vibratory equipment on the conventional isolation mounting is not dissipated and transforms, isolated and this part vibrational energy of outwards not transmitting will aggravate the vibration of equipment self, easily cause equipment failure.For pump machines equipment, owing in the fluid of carrying, also include this vibrating source of pressure pulsation, common isolation mounting does not have inhibitory action to this fluid pulsation, and the pressure pulsation that fluid carries can cause the integral vibration isolation usefulness of isolation mounting to lose efficacy to the vibration of the pipeline excitation of delivery fluid.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of vibration absorber at the deficiency of above-mentioned prior art existence, this device can reduce the amplitude of pump vibration, and can transmit the vibrational energy of pump out, reduce the harm that equipment caused because of vibration, and can effectively suppress to avoid the exciting of pipeline from the pressure pulsation of the fluid of pump outflow.
The present invention for the technological scheme that technical problem adopted of the above-mentioned proposition of solution is: comprise vibration damper 3, different is, also include rigid body 2 and rectification runner joint 11,11A, described rigid body 2 is provided with mounting platform 8, be provided with rectification runner 5 in the rigid body 2, current plate 6 is housed in the rectification runner, and described rectification runner joint 11,11A dock and are fixed on the rigid body 2 with the rectification runner, and the bottom of rigid body and side are installed on the vibration damper 3 that links with fixed base and support.
Press such scheme, be installed on pump 1 on the described mounting platform, delivery side of pump joins through outer pipe 13 and rectification runner joint 11; Also comprise thanksing for your hospitality property adapter 4,4A, described disturbing property adapter 4,4A are connected by flange 12 with rectification runner joint 11,11A respectively, and wherein the disturbing property adapter 4 of an end is serially connected between outer pipe 13 and the rectification runner joint 11.
Press such scheme, corresponding current plate is provided with current plate lid 7 on the described rigid body 2, and described current plate 6 traverses in the cross section that is arranged on rectification runner 5; Described rectification runner 5 is bending shape, and current plate 6 is arranged on the corner of bending, tiltedly wears the rectification cross section of fluid channel; Described current plate 6 is orifice structure or cell structure.
Working principle of the present invention is: the vibrational energy of pump 1 is directly delivered on the rigid body 2, and the mass effect that rigid body 2 the produces alternation excitation force that 1 running produces to pump produces the effect that cushions and stabilize, and has reduced the peak value of vibration wave; Rectification runner 5 and the current plate 6 fluid pulsation amplitude that pump 1 produces that can decay reduces the pipeline flow noise, has also reduced the exciting effect of fluid to pipeline; Rectification runner 5 and current plate 6 are set in rigid body, can utilize the mass effect of rigid structure further to reduce the amplitude of pulsating fluid excited vibration; The flexibility connection pipe of installing between the outer pipe 13 of pump 1 and rectification joint 11 4 can reduce to produce the pipeline internal stress because of the pipeline installation deviation; Vibration damper 3 reaches the optimum state at its absorbing anti-vibration performance of main stress direction.
Beneficial effect of the present invention is: 1) mass effect of the rigid body generation alternation excitation force that running produces to vibratory equipment plays the effect that cushions and stabilize, and has reduced hazard of vibration; 2) on a plurality of supporting surfaces of rigid body, be connected to vibration damper, can obtain better absorbing effectiveness in vibration suppression; 3) rectification runner and current plate reduce the pipeline flow noise, have reduced the exciting effect of fluid to pipeline; 4) adapter of disturbing property can reduce to produce because of the pipeline installation deviation internal stress of pipeline; 5) use nonmetallic coating and prevent corrosion, can improve the reliability of vibration absorber and prolong its working life.
