Abstract
The invention discloses a cooling fan which includes a motor rotating shaft and a cylindrical wheel hub fixed on the motor rotating shaft. Blades are arranged on the cylindrical wheel hub. The cylindrical wheel hub and the blades are formed in an integral die-cast mode. A blade angle of every blade is 12 degrees to 15 degrees, and the cylindrical wheel hub and the blades are in alloy aluminum material. According to the cooling fin, A problem in the prior art that normal operations and cooling effect can not be achieved due to the fact that the cooling fan can easily break blades off is solved, and the strength of blade roots is improved through the integral die-cast formation of the cylindrical wheel hub and the blades. Besides, the blade thickness is increased and the blade angle is reduced so that the strength of fan blades and the requirement of air quantity are guaranteed, the working air pressure requirement of an accelerator is met, the operation is stable and the service life is long.
Description
Technical field
The present invention relates to a kind of cooling blower, belonged 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 the 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.
Summary of the invention
Technical problem to be solved by this invention 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 technical solution adopted in the present invention is:
A kind of cooling blower comprises motor drive shaft and is fixed on the described cylindrical shape wheel hub that reaches on the transmission shaft that on the described cylindrical shape wheel hub blade is installed, 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 invention has the beneficial effects as follows: by with wheel hub and blade integral die cast, strengthened the intensity at blade root place, increased simultaneously vane thickness 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 present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with Figure of description, the present invention 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, tried normal operation out.
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 airfoil is equipped with the cooling blower of conforming blade angle blade, has the blade strength height, and blade is frangibility not, operates steadily, and the 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 provided by the invention 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 invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
