5-48 centrifugal fan
Patent No.:
5-48 centrifugal fan
1 Uses
5-48 centrifugal fan with electric arc furnace main Granville purification device for smoke exhaust emission requirements , to improve the working environment of the workshop to ensure that the work area EAF dust concentration to achieve " industrial enterprise standard" fixed and design, can also be used other performance requirements in the same variety of occasions.
(2) in the form
Fans of the series composed by the 5,5.5,6,10,10.5,11,11.5,12.5 eight machine number , the fan can be made of left and right-handed forms. Impeller from the motor side for clockwise rotation clockwise to the "right ," said the counterclockwise rotation of Wei L , with " left". Fan outlet to the cabinet position of the outlet angle . " Right-left " can be made 0 °, 90 °, 180 ° three kinds of angles. Fans of the series all use D -type transmission .
3 Structural features
The products of formula Y5-47 according to the dimensionless design similar characteristics , that is maintained per Y5-47 is simple in structure , high efficiency , low noise characteristics, and purification apparatus according to furnace dust emission requirements , and electric furnace dust features increases the plate and two kinds of plum petals adjust the door , the fan over a wide flow range.
Arc cone fan with front disc straight blade and convergent inlet arc , constitutes a reasonable flow path reduces the eddy zone. Internal fan to reduce the losses , noise, slightly higher than 80dB, industry-standard maximum total pressure efficiency of 90%. Taking into account the reliability and advanced adjustment , adjust the product structure of the door using the external drive , can be manually adjusted, and according to user needs can also be angular displacement actuators to automatically adjust ( from top to bottom pull fully closed to fully complete in regulating the opening ) adjust the range of 0 ° ~ 90 °.
EAF dust rot under slightly weaker characteristics , according to the actual needs of users of the product of the impeller , casing inlet , adjust doors and other parts , respectively , and Q345 used 1Cr18Ni9Ti two different materials , the corresponding expanded its product range to adapt .
To meet the requirements of EAF dust medium heat for extended product life of the cooling and lubrication products take the following measures:
Cooling : chassis back plate and bearing housing air- cooled aluminum impeller one , to reduce the temperature of the bearing housing , the bearing box temperature to ensure the specified range .
Lubrication: high molybdenum disulfide grease . Taking into account the principle that if the furnace blower operating characteristics , in order to ensure safe operation of the motor , can be equipped with JD-1 three-phase asynchronous motor is a single -phase protection , to prevent burning motor .
