The 5-12 industrial centrifugal blower brings meaningful improvements over previous 5-11 generations. It meets customer requirements for higher volume air output. Similar to 5-11 centrifugal fans in functions, the latest 5-12 air and gas handling equipment is commonly used to convey gases and hard materials. Specific applications include the following.
1. Draft inducers for industrial boilers, cement production lines, or circulating fluidized bed systems
2. Flue gas discharge, flue gas desulphurization, or flue gas denitration
3. Blower fans for coke ovens
4. Blower fans for drying systems, industrial dust collector fans, blowers for industrial waste heat recovery
5. Blower fans for sinter machines
6. Smoke and heat exhaust fans
Features of Industrial Centrifugal Blower
1. Designed specially for material handling fan applications that involve high temperature, wear and corrosion, the 5-12 industrial centrifugal blower delivers relatively high pressure, large-volume air output while generating low noise.
2. Annealing process removes any internal stresses of the impeller caused by welding, making it unlikely to deform or crack.
3. Different combinations of belt and pulley provides variable rotating speeds, allowing the industrial centrifugal blower always to operate at peak efficiency point thereby saving energy.
4. Linear guides are added to facility belt tightening, minimizing the energy loss caused by a slack belt.
5. There is space left inside the bearing housing to allow for the installation of temperature sensor and vibration sensor which would facilitate the monitoring of fan operating status.
6. Liquid lubricating grease is used to reduce friction. Replacement or refilling of lubricating grease can be done without the need to open the journal box. Via the sight glass, centrifugal blower users can observe the oil level and oil quality.
7. Dynamic balancing eliminates any unbalance that might affect the running stability.
8. Each medium-pressure industrial centrifugal blower needs to pass the test run and vibration check before leaving factory.
