Abstract
The utility model discloses a cooling fan. The cooling fan comprises a motor transmission shaft and a cylindrical hub fixed on the motor transmission shaft, blades are mounted on the cylindrical hub, the cylindrical hub and the blades are integrally formed by die casting, a blade angle of each blade ranges from 12 degrees to 15 degrees, and the cylindrical hub and the blades are made of alloy aluminum. The cooling fan solves the problem that a cooling fan in the prior art is prone to breakage of blades, cannot operate normally and cannot achieve cooling effect. By the aid of integral die casting formation of the hub and the blades, strength of blade roots is enhanced, blade thickness is increased while blade angle is decreased, blade strength is guaranteed, requirement on air volume is met, air pressure requirement of working of accelerators is met, operation is stable, and service life is long.
Description
Technical field
The utility model has related to a kind of cooling blower, belongs to the ventilation equipment technical field.
Background technique
For guaranteeing that electron accelerator normally moves, the operating temperature in the accelerator master steel cylinder is controlled in allowed band.Accelerator master steel cylinder operating temperature is generally about 35 degree.Cooling to the heating component in the accelerator master steel pipe is very important.The cold-trap that employing is installed in the accelerator master steel cylinder is the best approach of head it off, and its effect makes the interior gas of accelerator master steel cylinder obtain mandatory circulation, by heat exchanger heat is taken away.The cooling blower of required configuration is a vitals of cold-trap in the cold-trap, and general general cooling air is confidential 6.5 kilograms of medium-term and long-term operations of insulation gas, and the existing cooling blower blade that fractures easily can not normally move, and does not reach cooling effect.
The model utility content
Technical problem to be solved in the utility model provides a kind of cooling blower, cooperates special blade, strengthens the intensity at blade root place, satisfies the requirement of air quantity when guaranteeing the intensity of fan blade, operates steadily long service life.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of cooling blower comprises motor drive shaft and the cylindrical shape wheel hub that is fixed on the described motor drive shaft, on the described cylindrical shape wheel hub blade is installed, and described cylindrical shape wheel hub and blade are that integral die-cast forms.
Aforesaid a kind of cooling blower is characterized in that: the blade angle of described blade is 12 °-15 °.
Aforesaid a kind of cooling blower is characterized in that: cylindrical shape wheel hub and blade are the alloy aluminum material.
The beneficial effects of the utility model are: by with wheel hub and blade integral die cast, strengthened the intensity at blade root place, increased vane thickness simultaneously and reduce the leaf angle, the intensity of assurance fan blade reaches the requirement to air quantity, meet the air pressure requirement of accelerator work, operate steadily long service life.
Description of drawings
Fig. 1 is the structural representation of a kind of cooling blower of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with Figure of description, the utility model is described further.
As depicted in figs. 1 and 2, a kind of cooling blower, comprise motor drive shaft 1 and be fixed on the described cylindrical shape wheel hub 2 that reaches on the transmission shaft 1, on the described cylindrical shape wheel hub 2 blade 3 is installed, described cylindrical shape wheel hub 2 forms for integral die-cast with blade 3, the blade angle of described blade 3 is 12 °-15 °, and cylindrical shape wheel hub 2 is the alloy aluminum material with blade 3.The air efficient of cooling blower brings up to 84% from original 67%, and strengthened the intensity at blade root place, meet the requirement of accelerator operating air pressure, increased the thickness of blade 3, reduced the leaf angle, with the intensity of assurance fan blade and the requirement of air quantity, once in 16 kilograms of insulating gass, to try out, operation is normal.
This draught fan impeller diameter is 300 millimeters, rotating speed is 1450 rev/mins, total head 4.6 column, air efficient 78%, shaft efficiency 0.0155kw, the motor of joining power 0.55kw, after will noting cooling blower motor 1 and support is connected during installation, being suspended on must be firm on the cold-trap frame, and cooling blower impeller center must be consistent with the center, wind-tunnel hole that cold-trap is sealed up a door, the quantity of cooling blower can be decided according to the size of cold-trap area.
Through using proof, this novel aerofoil profile is equipped with the cooling blower of conforming blade angle blade, has the blade strength height, and blade is frangibility not, operates steadily, and characteristics such as long service life have now been used on the accelerator of Jiangsu Dasheng Accelerator Manufacturing Co., Ltd.'s development.
In sum, a kind of cooling blower that the utility model provides cooperates special blade, strengthens the intensity at blade root place, satisfies the requirement of air quantity when guaranteeing the intensity of fan blade, operates steadily long service life.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
