Single Stage High Speed Centrigugal Blower Fan Turbine Vacuum Pump
With Overhung Structure
GLF mode draught fan is with sing-stage overhung structure. The air
suction is in axial direction, and the air exhaust is in radial
direction. Moist air goes through the gas water separator entering
to suction tube and guide vane. And the air will discharge from the
boiler room through vaneless diffuser.
Energy-saving: it adopts ternary impeller design which has good
startup performance. The efficiency can be 83~87%. The efficiency
of the centrifugal fan is 20~25% higher than water ring vacuum
pump, and its energy-saving is 20~25% more than water ring vacuum
Waste-heat utilization: the air compressed through the high speed
centrifugal fan can reach 140℃ temperature. The high temperature
gas can recover heat energy through heat exchange. And it can also
used to supply fresh air of dryer section and used to heat the
Water saving: it is no need water as working liquid, so it can save
water and reduce water treatment cost.
The structure is compact, and the floor space is small.
High reliability: no working liquid, so it can completely solve
corrosion and fouling problem of water ring vacuum pump.
GLF mode high speed centrifugal fan is specially designed for
vacuum used by paper mill. The air capacity is 100~650 m3/min, and
the vacuum degree is 30~65kpa. It uses sing-stage or double-stage
overhung impeller, gearbox, sliding bearing and its lubrication is
pressure oil supply. It is widely used in vacuum device in paper
mill, sewage treatment, electric power and pneumatic transport and
The characteristics of GLF fan are extensive applicability,
remarkable energy-saving effect, small footprint and simple
installation, operation and maintenance.
