后倾离心风机HRW Forward fan

1.the volute select the high quality cold rolling steel plate either the pot galvanize steel plate knee bend weld the system or use nip the shape of the mouth type manufacture. Its line is the logarithmic spiral curve; the lift-drag ratio is good.
 
2.The air blower air outlet may 0°, 90°, 180°, 270° four kind of position installments, like the following chart.
 
3. Before the impeller central disk, side the plate, the curved circular arc leaf blade is the ramming formation, the impeller assembly uses rolls the rivet. The impeller transient equilibrium quality rank is the G5.6 level. Impeller material is aluminum.
 
4.The main axle use the high quality carbon steel to make and to pass through the quenching and tempering, phosphorization rust prevention processing, the safety performance is good.
 
5. The inlet use the high quality steel plate after the spinning formation, guaranteed that the air enters the impeller to import the section evenly, reduces the flowing to lose greatly, raises impeller's efficiency.
