Description
Technical field
The utility model relates to blower fan, relate in particular to a kind of exhaust outlet be provided with Sealing can damping blower fan.
Background technique
Blower fan is that China is called for short the custom of gas compression and gas conveying machinery.Usually said blower fan comprises ventilator and blower.Gas compression and gas conveying machinery are that the mechanical energy of rotation is converted to gas pressure energy and kinetic energy, and the machinery that gas is transferred out.The main structural components of blower fan is the motor of impeller, casing, intake grill, exhaust outlet and drives impeller etc.
In Chinese Patent Application No., be 2004100576987, within open day, be February 23 in 2005 day, be called in the patent documentation of " blower " and disclose a kind of blower fan.During use, airduct is docking together and realizes drawing of wind with exhaust outlet sealing.The mode that existing airduct connects with exhaust outlet has two kinds: a kind of is to adopt metal airduct, by the mode of welding, realizes being tightly connected of airduct and exhaust outlet, although this Placement sealing reliability is good, inconvenient when connecting and dismantling; Another kind of is to adopt soft airduct (as rubber pipe), and duct sleeve is located on exhaust outlet, then by anchor ear, holds to realize being tightly connected tightly, although this Placement is easy to connect, joint easily produces (the being poor sealing) phenomenon of leaking out.
Existing blower fan ubiquity is following not enough: exhaust outlet and airduct can not facilitate and be sealed connected together reliably; , also there is the poor deficiency of vibration isolating effect in the equipment that the vibration meeting transmission that blower fan when running produces links together with blower fan to it and affect the use of this equipment; The lack of homogeneity of the wind flowing out from exhaust outlet, and the blower fan of lack of homogeneity can cause the poor accuracy of test data while being applied to wind tunnel test.
Model utility content
First object of the present utility model aim to provide a kind of can make airduct convenient and with exhaust outlet, be sealed connected together reliably, can reduce exhaust outlet that blower fan passes to the vibration of the equipment that blower fan is installed be provided with Sealing can damping blower fan, solved exhaust outlet can not be not only convenient but also with airduct, be sealed connected together the problem that the vibration producing with blower fan can be interfered the equipment that same blower fan is connected reliably.
Second object of the present utility model be intended to further to provide on the basis of the first object a kind of exhaust outlet of good uniformity of wind of outflow be provided with Sealing can damping blower fan, solved the problem of the lack of homogeneity of the wind that existing blower fan flows out.
Above technical problem solves by following technical proposal: a kind of exhaust outlet be provided with Sealing can damping blower fan, comprise casing, described casing is provided with intake grill and exhaust outlet, in described casing, be provided with and wind be transported to the impeller of exhaust outlet from intake grill, described exhaust outlet stuffing box gland is provided with seal ring, the axial end that described seal ring is positioned at the outlet end place side of exhaust outlet is provided with the annular seal groove circumferentially extending along seal ring, the madial wall of described seal groove is provided with some annular seal lips that circumferentially extend along seal groove, described sealing lip is along the axial distribution of seal ring, the free end of described sealing lip tilts towards the direction away from seal groove diapire, described casing is provided with rubber seat, the bottom surface of described rubber seat is provided with deformation chamber, described deformation is provided with dividing plate in chamber, described dividing plate is divided into upper liquid storage cylinder and lower liquid storage cylinder by described deformation chamber, described dividing plate is provided with the main damp channel that is communicated with described upper liquid storage cylinder and lower liquid storage cylinder, in described main damp channel, be provided with energy-absorbing plate, described energy-absorbing plate is equipped with the damper rod that can slide along the vertical direction, described damper rod is provided with a damp channel, the lower end of described lower liquid storage cylinder is provided with the bowl-type serum cap arching upward towards lower liquid storage cylinder inside.During use, duct sleeve is located on exhaust outlet and airduct end is inserted in seal groove, in the process that airduct inserts, make sealing lip produce deformation and airduct is connected to sealing lip sealing realize being together tightly connected of airduct and exhaust outlet, then by existing fixed block (as anchor ear or band), airduct is fixed together with exhaust outlet.By liquid filling in deformation chamber, the utility model contacts connection by rubber seat with other equipment, the vibration that blower fan produces passes to rubber seat and while causing the distortion of deformation chamber, deformation chamber distortion and drive that position liquid in the inner flows back and forth between upper liquid storage cylinder and lower liquid storage cylinder, the rocking of energy-absorbing plate and damper rod, flow of fluid and energy-absorbing plate and damper rod rock and in process, change vibrational energy into heat energy and consume.If vibration is compared with little and be not enough to impel deformation chamber when distortion, now only have rocking of liquid, during liquid sloshing, damper rod produces and rocks and energy-absorbing, damper rod is set and can improves the absorption that high frequency is vibrated by a narrow margin, make the utility model not only can absorb high amplitude vibrational energy, can also absorb the vibrational energy of low-amplitude, so vibration isolating effect is more.Because the free end of sealing lip tilts towards the direction away from seal groove diapire, make wind in exhaust outlet ooze people to sealing lip during with the joint of airduct, blast can further drive sealing lip distortion and be connected to more reliably on airduct, therefore the higher sealing effect of air-out blast of blower fan will be better, sealing while also realizing high blast without giving in advance large pretightening force, makes also can assemble like a cork when the sealing that meets high blast.
