The utility model discloses a draw -in groove that forms between fixture block on the mount and ring can block the cooling tower with the contact surface department of cooling tower at the end cover, increases the fan and installs the stability on the cooling tower, reduces the fan and rocks to strengthen the volatile stability of steam, increased the refrigerated effect of cooling tower.
Description
Technical field
This utility model relates to technical field of motors, is specifically related to a kind of blower fan of cooling tower Special top cup。
Background technology
Cooling tower (Thecoolingtower) uses water as circulating coolant, absorbs heat dissipation to air, to reduce the device of water temperature from a system;It is cold is utilize water to carry out cold and hot exchange with air flowing after contacting to produce steam, steam volatile zone is walked heat and is reached waste heat that the principles such as evaporative heat loss, convection heat transfer' heat-transfer by convection and radiant heat transfer produce in leave industrial or refrigeration air-conditioner to reduce the evaporating radiator of water temperature, to ensure the properly functioning of system, device is generally tubbiness, therefore named for cooling tower。The process of steam volatilization wherein needs to use blower fan, and is driven flabellum to be fallen by steam fan by blower fan。
Application number is the Chinese patent of 201220167652.0, disclose a kind of end cover of fan, including cylindrical end lid, the fan shaft hole being arranged on end cover body center, it is characterized in that: the side of described end cover body fan shaft hole is provided with the two pieces of breach being symmetrically distributed, and is provided with reinforcement between described two pieces of breach。The end cover of fan that this utility model provides conveniently is observed blower fan function situation in the course of the work, is solved the ventilation and heat of blower fan and alleviate the weight of end cover of fan, save and make material, and add fixing boss in end cover of fan fixed area, avoid the abrasion of fixed area, add the life-span of end cover of fan, have a good application prospect。
This patent is disadvantageous in that, usual blower fan is in use in being vertically arranged, and the setting of its tabs is when making fan operation, blower fan is unstable with the connection of cooling tower, when causing flabellum to rotate, blower fan is followed and is rocked so that flabellum produces sinuous flow with steam contact position, affects the volatilization of steam in cooling tower。
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide the blower fan of cooling tower Special top cup of a kind of stable connection。
For achieving the above object, this utility model provides following technical scheme:
A kind of blower fan of cooling tower Special top cup, including lid, the shaft hole for fan shaft traverse is offered in the middle part of lid, covered body wall is additionally provided with the some pieces of fixed mounts for being connected with cooling tower, described fixed mount is provided with fixture block, it is provided with the annulus being arranged concentrically with shaft hole in the middle part of lid, between fixture block with annulus, forms the draw-in groove being connected with cooling tower。
Of the present utility model being further arranged to: described fixture block is provided towards the arcwall face away from shaft hole relative to the opposite side of shaft hole, the arc of arcwall face and shaft hole are arranged concentrically。
Of the present utility model it is further arranged to: the medial wall of described annulus offers annular chamfer。
This utility model has the advantage that this utility model passes through the fixture block on fixed mount and the draw-in groove formed between annulus, cooling tower can be blocked at the contact surface place of end cap Yu cooling tower, increase assembling stability on cooling tower, reduce blower fan to rock, thus strengthening the stability of steam volatilization, add the effect of the cooling of cooling tower。
Accompanying drawing explanation
Fig. 1 is the axonometric chart of blower fan of cooling tower Special top cup。
Accompanying drawing labelling: 1, lid；2, mounting blocks；3, shaft hole；4, fixed mount；5, fixture block；6, annulus；7, arcwall face；8, arc groove；9, annular chamfer；10, draw-in groove。
Detailed description of the invention
With reference to accompanying drawing, this utility model is described further。
A kind of blower fan of cooling tower Special top cup, including lid 1, the shaft hole 3 for fan shaft traverse is offered in the middle part of lid 1, lid 1 sidewall is additionally provided with the some pieces of fixed mounts 4 for being connected with cooling tower, described fixed mount 4 is provided with fixture block 5, it is provided with the annulus 6 being arranged concentrically with shaft hole 3 in the middle part of lid 1, between fixture block 5 with annulus 6, forms the draw-in groove 10 being connected with cooling tower。This utility model blocks cooling tower by the draw-in groove formed between the fixture block 5 on fixed mount 4 and annulus 6 at the contact surface place of end cap Yu cooling tower, increase assembling stability on cooling tower, reducing blower fan to rock, thus strengthening the stability of steam volatilization, adding the cooling effect of cooling tower。Wherein, fixed mount 4 is preferably arranged to three, spaced 120 degree, in order to ensure stability when using。The sidewall of annulus 6 is provided with arc groove 8, it is possible to conveniently this end cap is installed, and increases the stability being connected between end cap installation rear fan and cooling tower；Being additionally provided with mounting blocks 2 on the sidewall of end cap, mounting blocks 2 and fixed mount 4 stagger mutually, it is to avoid stopped by the other side during each self installation and affect installation effectiveness。The length of fixed mount 4 is more than mounting blocks 2, the length that fixed mount 4 increases can expand the contact area of end cap and cooling tower, thus increasing the stability of assembling, and reduces the pressure that fixed mount 4 is subject to cooling tower junction, reduce the abrasion on fixed mount 4, increase the service life of end cap。
Described fixture block 5 is provided towards the arcwall face 7 away from shaft hole 3 relative to the opposite side of shaft hole 3, and the arc of arcwall face 7 and shaft hole 3 are arranged concentrically。When the setting of this arcwall face 7 makes end cap install, can be arranged on cooling tower with different angles, add convenience during installation, accelerate installation effectiveness。Meanwhile, compared to other set-up modes, when this arcwall face 7 also makes blower fan rock, the area that blower fan is rocked by restriction is bigger, further increases assembling stability on cooling tower。
The medial wall of described annulus 6 offers annular chamfer 9。Owing to this blower fan is exclusively used on cooling tower, and humidity in cooling tower is bigger, blower fan is under this kind of environment, it is easy to the phenomenon got rusty, except arranging the antirust paint of necessity except blower fan, it is also desirable to smear certain lubricating oil, especially rotating shaft place, the fluency of axis of rotation can not only be increased, and be prevented from rotating shaft place and get rusty。And the open surface of rotating shaft and shaft hole 3 sidewall can be expanded by this annular chamfer 9, this is made to be in when adding lubricating oil, will not trickle to the lid 1 of end cap, not only reduce waste, and the lubricating oil increased also can be made full use of by rotating shaft, reduce the probability that rotating shaft place is got rusty, increase the service life of blower fan。
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model。It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model。
