5-11D Medium Pressure Centrifugal Fan

5-11 medium pressure centrifugal fan can be used for conveying various common gas and hard materials in industrial production, suitable for high temperature, wear, corrosion and other poor conditions. It is widely used in: Clinker cooler system, power generation, papermaking, Materials drying, Industrial dust collector /filtration system, flue gas desulfurization, flue gas denitration, industrial boiler inducing air, cement production line, Industrial waste heat recovery device, mineral sintering, coke production (coke oven), etc. This fan is one of the most widely used fans in poor working conditions in SIMO BLOWER.

1. Can output higher discharge pressure, in the same time provide larger air flow volume, low noise. Can work stably under high temperature conditions
2. Can flexibly adjust fan’s volume and pressure in running by air damper. Can also adjust fan’s pressure and volume by changing the fan speed via matching variable frequency motor.
3. Cooling method of bearing, chooses low cost water cooling method or good heat dispersion oil cooling method according to gas temperature and running condition. Or install BOX COOL for very high temperature medium condition to protect fan system operation reliable completely.
4. Regarding to material of impeller and main shaft, we will choose high strength carbon steel, low alloyed steel, High temperature resistant alloy steel, High temperature resistant high strength alloy steel according to different medium temperature and running speed, ensuring the impeller and main shaft keeping reliable strength in high temperature.
5. Can satisfy different dust loading conditions from low dust loading to large dust loading, the surface hardness of impeller can reach to HRC60~70 after special processing, greatly extend impeller’s service life.
6. Bearing housing reserves installation place for temperature and vibration sensors, can install easily of fan running monitoring device.
7. The welding line of impeller and main shaft passed ultrasonic flaw detection, ensuring no defect of welding and materials, guarantee strength.
8. Running test and vibration value test for fans is done after finishing manufacturing, ensuring reliable running
