Description
Technical field
This utility model relates to a kind of blower fan, specifically, relates to a kind of blower fan of cooling tower, belongs to industrial equipment technology neck
Territory.
Background technology
Cooling tower is mainly used in industrial circle and the civil air conditioner cooling systems such as electric power, metallurgy, petrochemical industry, weaving,
Being a kind of equipment taking in air by the used heat produced in commercial production, these used heat enter cooling tower in the way of hot water,
Making temperature retreat through pervaporation and conduction of heat, then recirculation uses to commercial production, and during this, cooling blower plays
Effect be by drive tower inner air and outer air convection current, by outside fresh natural air carry come in hot water generation heat exchange also
Producing steam, then vapours discharged outside tower, the working environment residing for blower fan belongs to hot and humid environment, and existing cooling tower
Blower fan nearly all lacks the moistureproof anti-corrosion function of necessity, although the material that support flabellum is generally selected is excellent anti-corrosion performance
Rustless steel, but the stalloy of blower interior and electronic-circuit-component are also highly prone to the erosion of humid air, thus affect wind
The normal operation of machine and service life, needing time-based maintenance and maintenance, expend substantial amounts of manpower and materials, economic benefit is extremely low, because of
This, a kind of blower fan of cooling tower possessing Moisture-proof corrosion-proof ability is urgently released.
Utility model content
The problems referred to above existed for prior art, the purpose of this utility model is to provide a kind of blower fan of cooling tower, solves
Certainly for want of Moisture-proof corrosion-proof measure of existing blower fan of cooling tower and the motor corrosion that exists and circuit board make moist short circuit problem, improve
Utilization rate of equipment and installations, increases the service life.
For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is as follows:
A kind of blower fan of cooling tower, including support, impeller, motor and protective cover, wherein, support is arranged on cooling tower top,
Motor is arranged in support, and impeller is fixing with the output shaft of motor to be connected, and the stalloy outer surface of motor has antirust paint, electricity
Being coated with one layer of moistureproof glue on the circuit board of machine, protective cover covers whole impeller and is movably connected on support.
Preferably, antirust paint uses water-based metal antirust paint, has no side effect, and protection effect is excellent.
It is highly preferred that antirust paint uses iron red alcohol acid paint, adhesive force is good, and hardness is big, flexible, shock resistance, rust-proof effect
Excellent.
Preferably, it is contemplated that usability and assembleability, the antirust paint thickness of dynamo sheet is 10～30um.
Preferably, moistureproof glue uses silicone resin, protects good stability, and humidity resistance is excellent.
Preferably, it is contemplated that barrier propterty and cost factor, the thickness of moistureproof glue is 10～25um.
Preferably, the lobe numbers of impeller is preferably three, has preferably air quantity characteristic, and antipyretic ability is strong.
It is highly preferred that the blade of impeller uses wing-shaped structure, blade upper and lower surface pressure reduction is relatively big, has preferably blast
Characteristic, anti-back pressure ability is excellent.
Preferably, motor is two-pole machine, has preferably output characteristics.
Preferably, protective cover covers whole impeller and is spirally connected with support, is beneficial for disassembly and assembly and overhauls.
Relative to prior art, the beneficial effects of the utility model are: by the motor of blower fan of cooling tower and circuit part
Point carrying out antirust treatment and damp-proof treatment, the significant increase antirust corrosion-proof performance of blower fan, the operating adding blower fan is stable
Property and reliability, be greatly improved the service life of blower fan, significantly improve economic benefit.Therefore, there is the most wide answering
By prospect and splendid promotional value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of blower fan of cooling tower preferred embodiment that this utility model provides.
Detailed description of the invention
Make this utility model with preferred embodiment below in conjunction with the accompanying drawings further to illustrate detailed completely.
The preferred embodiment structural representation of a kind of blower fan of cooling tower that Fig. 1 provides for this utility model.As it is shown in figure 1,
This blower fan of cooling tower includes support 1, impeller 2, motor 3 and protective cover 4, and wherein, support 1 is arranged on cooling tower (not shown)
Top, motor 3 is arranged in support 1, and impeller 2 is fixing with the output shaft 31 of motor 3 to be connected, and the lobe numbers of impeller 2 is three,
Having bigger air quantity, antipyretic ability is strong, and blade uses wing-shaped structure, and blade upper and lower surface pressure reduction is relatively big, has preferably
Air pressure characteristics, anti-back pressure ability is strong, and motor 3 uses two-pole machine, has preferably output characteristics and output, motor 3
The iron red alcohol acid antirust paint that stalloy 32 outer surface has a layer thickness to be 20um, the circuit board 33 of motor 3 is coated with one
Layer thickness is the silicone resin protection against the tide glue of 15um, and protective cover 4 covers whole impeller 2 and is spirally connected with support 1.
This blower fan of cooling tower by motor and circuit part are carried out antirust treatment and damp-proof treatment, significant increase blower fan
Antirust corrosion-proof performance, add run stability and the reliability of blower fan, be greatly improved the service life of blower fan, significantly
Improve economic benefit, great application prospect and promotional value.
Finally it is necessary described herein: above example is served only for making the technical solution of the utility model further
Explaining, it is impossible to be interpreted as the restriction to this utility model protection domain, those skilled in the art is new according to this practicality
