Product Introduction:
The USES of the fan
8-9, 9-12 type high pressure centrifugal fan is melting at a rate of 1, 2, 3, 5, 7 t/h cupola supporting dedicated fan, also can be used as all kinds of furnace, forging furnace smelting blast and transport non-corrosive, spontaneous combustion, gas containing viscous material, also can choose other similar performance, but the medium temperature shall not exceed 80 ℃, the dust content in the medium and hard particles is not more than 150 mg/m3.
Ii. Type of fan
1, 8-09, 9-12 fans are single inhalation, 8-09 fans, the design number of our company is numbered 6.8A, 7.1D, 8D, 8.5D, 9D. The number of the model 9-12 fan designed by our company is numbered № 6.8A, 7.1A, 7.4D, 7.7A, 8D and 9D.
2, 8-9. Model 9-12 fan housing made of clockwise rotation or counterclockwise rotation of the two types.
3. The outlet position of the fan is represented by the outlet Angle of the shell. The "straight" and "inverse" fan shells are made into 0 degrees, 90 degrees and 180 degrees.
Iii. Fan structure
The fan is mainly composed of impeller, casing, air inlet, transmission set, sealing parts and machine stand.
1. Impeller: The impeller is designed according to the new efficient forward fan theory. After the impeller is formed, it runs smoothly after static and dynamic balance correction.
2. Casing: The whole of the spiral shell is welded with ordinary steel plates.
3. Air inlet: It is made into the integral structure of collecting and collecting streamline, which is fixed on the front cover plate with bolts.
4. Transmission set: composed of spindle, bearing box, coupling, etc. The main shaft is made of high quality steel, bearing box integral structure. The rolling bearing shall be lubricated with grease.
