Abstract
The utility model discloses a two-stage vibration damper of a fan and aims at providing a vibration damper capable of relieving the pollution of vibration noises of the fan, purifying the environment and favoring the health of surrounding people. A spring damper is arranged between a base of a fan vibration damping rack and a vibration damping pedestal, and a rubber vibration damping pad is fixed between the vibration damping pedestal and the assembling ground of the fan. The solidness of the rubber vibration damping pad is 50-60 degrees. The vibration damper decreases the resonance frequency of the fan and the vibration damping rack through the spring damper as first-stage vibration damping and conducts second-stage vibration damping on the fan through the vibration damping pedestal and the rubber vibration damping pad to further weaken the vibration energy of the fan. Through two-stage vibration damping, the vibration damper eliminates most of vibration energy, relieves the pollution of vibration noises of the fan, purifies the environment, ensures the health of surrounding residents and is beneficial to prolonging the service life of a building.
Description
Technical field
The utility model relates to a kind of vibration damping equipment, in particular, relates to a kind of two-stage vibration damping equipment that is applicable to blower fan.
Background technique
At present, for the needs of constructure ventilation, blower fan is installed on building.The running of blower fan produces very big vibrating noise.Though blower fan generally is installed on the vibration damping stand,, the vibration damping degree is limited, the environment around the use of blower fan has influenced, personnel's life has influenced the healthy of surrounding resident around disturbing.And for a long time vibration also causes to a certain degree destruction to building.
The model utility content
The utility model is in order to overcome deficiency of the prior art, a kind of pollution that can alleviate the fan vibration noise to be provided, and environment purification helps the healthy blower fan two-stage vibration damping equipment of personnel on every side.
The utility model is achieved through the following technical solutions:
A kind of blower fan two-stage vibration damping equipment, it is characterized in that, comprise spring cushion, vibration damping pedestal, rubber damper, between the base of blower fan vibration damping stand and vibration damping pedestal, spring cushion is installed, install between the ground at vibration damping pedestal and blower fan and be fixed with rubber damper.
The hardness of described rubber damper is the 50-60 degree.
Described spring cushion is a plurality of, and the area of plane that a plurality of spring cushions constitute should be greater than the plane projection area of vibratory equipment.
Described rubber damper is a plurality of, and the area of plane that a plurality of rubber dampers constitute should be greater than the plane projection area of vibratory equipment.
The utlity model has following technique effect:
Blower fan two-stage vibration damping equipment of the present utility model as first order vibration damping, carries out second level vibration damping by vibration damping pedestal and rubber damper to blower fan by the resonant frequency of spring cushion reduction blower fan and vibration damping stand again, further slackens the energy of fan vibration.By the two-stage vibration damping, most vibrational energy is eliminated, alleviated the pollution of fan vibration noise, purified environment, ensured the healthy of surrounding resident.And, help prolonging working life of building.
Description of drawings
Fig. 1 is the plan view of the utility model blower fan two-stage damping device;
Fig. 2 is the side view of the utility model blower fan two-stage damping device.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The schematic representation of the utility model blower fan two-stage damping device as depicted in figs. 1 and 2, comprise spring cushion 3, vibration damping pedestal 4, rubber damper 5, between the base of blower fan 1 vibration damping stand 2 and vibration damping pedestal 4, spring cushion 3 is installed, installs between the ground at vibration damping pedestal 4 and blower fan and be fixed with rubber damper 5.
In order to reach best effectiveness in vibration suppression, the hardness of described rubber damper is the 50-60 degree.
Described spring cushion is a plurality of, and the area of plane that a plurality of vibration dampers constitute should be greater than the plane projection area of vibratory equipment.Described rubber damper is a plurality of, and the area of plane that a plurality of damping pads constitute should be greater than the plane projection area of vibratory equipment.The quantity of spring cushion is determined according to blower fan vibration damping stand weight.The quantity of damping pad, height and contact area are determined according to vibration damping pedestal and blower fan weight in working order.Can reach the vibration damping requirement gets final product.Utilize momentum theory, mv=m
1v
1, m is the noise equipment quality in the formula, v is a noise vibration equipment speed; m
1Be vibration damping pedestal quality, v
1Be vibration damping pedestal vibration velocity.Vibration damping pedestal quality is 4 times of noise equipment quality in this way, and then the vibration velocity of vibration damping pedestal reduces by 4 times.
The vibration that the blower fan running produces is delivered to spring damper through the vibration damping stand, reduces the resonant frequency of blower fan and vibration stand, and the control resonant frequency is about 5 hertz, and the vibration and noise reducing amount is 12.2 decibels.Vibration is through behind the spring damper, and the processing of secondary vibration damping is carried out in the vibration that blower fan is produced through vibration damping pedestal, Rubber shock-absorbing pad again, further slackens 70% of fan vibration energy, by the two-stage vibration reducing measure, can eliminate 95% of vibrational energy.
Although relate to a kind of blower fan two-stage damping device and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
