Product Description:
6-12 series high-pressure heavy-duty centrifugal fan, suitable for
conveying non-flammable gas and granule/powder/chip/fiber material
at normal temperature or high temperature.
The output gas flow is slightly larger than the 6-11 series
heavy-duty centrifugal fan, the air volume is large, and the
pressure is high, smooth operation, high reliability and long life.
It is widely used in industrial applications such as sintering
systems, large-scale dust collectors, feed/air supply/exhaustion of
large industrial rotary kiln/calcining kiln, air intake of large
boilers, and desulfurization and denitration of industrial waste
gas.
Features:
1. According to customer performance requirements customized
design, and optimized by CFD technology, the energy consumption is
lower than similar models.
2. The blade placement angle is optimized, more wear-resistant and
longer service life.
3. The variable inlet damper can be used to flexibly adjust the
pressure and flow of the fan during operation. The variable
frequency motor can also be selected to adjust the pressure and
flow of the fan by changing the speed.
4. The fan is equipped with temperature and vibration sensors,
which can easily install the fan operation monitoring device.
5. Made of high quality carbon steel, stainless steel or other
metal materials are available upon request.
6. Ultrasonic flaw detection on the welding seam and main spindle
of the impeller to ensure that there are no welding defects or
material defects and ensure the strength.
7. Bearing cooling method: according to gas temperature and
operating environment conditions choose low-cost water-cooling
method or oil-cooling method with good heat dissipation
performance.
For extremely high temperature operating conditions, can also be
installed with an electronic cooler, absolute protection of the
reliable operation of the fan system.
8. Large parts and components are disassembled and transported, so
that most parts can be loaded into containers for transportation,
saving you shipping costs.
9. Each component has an installation number. Under the guidance of
the installation manual, the system assembly can be completed
smoothly.
10. Provide on-site arrangement and guidance services.
