Power Saving Tips for Inline Centrifugal Duct Fan
A lot of related knowledge of inline centrifugal duct fans has been mentioned in the product introduction section.
In order to deepen everyone’s knowledge and understanding of this equipment, today we will further talk about how the equipment saves electricity during use.
Please see the following explanation.
➫ Control the radial clearance value between the air duct of centrifugal inline fans and the top of the blade.
The radial clearance value setting should be reasonable, too large or too small is not applicable.
➫ Reduce the resistance of the pipe network.
Before installation, the pipe size and installation location should be measured, make sure that the installation environment is suitable for stable operation of centrifugal duct fan, and install an inlet collector.
➫ Choose the appropriate inline centrifugal fan model.
Since there are many models of inline centrifugal duct fans, it is necessary to ensure that Miracle products can meet the requirements of use when selecting models, and do not allow them to be carried out in the low-efficiency area.
➫ If you need to use the inline centrifugal duct fan alone, the impeller and the motor should be well matched.
If the impeller and the fan are not matched, the energy consumption will increase.
In addition to the points introduced above, we must pay attention to the correct method of using duct fans when we use duct fans.
If the method is not used correctly, it will also increase the power loss.
➫ It is necessary to avoid overload during operation because the equipment is easily damaged due to long-term overload.
➫ If the operating environment temperature of the equipment is relatively high, the air density is high at high temperature, and the motor load of the fan will increase.
Therefore, in this case, try to avoid direct start, and use frequency conversion to start the inline centrifugal duct fan at a low frequency.
During the operation of the inline centrifugal duct fan, the staff should always pay attention to its operating status, observe the current and voltage conditions of the motor, and install protection devices to prevent equipment overload if necessary.
Maintenance of Inline Centrifugal Duct Fan
The Miracle inline centrifugal duct fan is composed of many components. If you want the safe and stable operation of the fan, you need to do a good job in the maintenance and maintenance of each component. Therefore, in the process of using the fan in ordinary times, it is necessary to master the maintenance and maintenance knowledge.
Maintenance of inline centrifugal duct fan impeller
The impeller is a component with a high failure rate in the fan system.
Therefore, it is necessary to regularly check whether the impeller has cracks, wear, dust, and other problems.
During the use of a centrifugal duct fan, it is necessary to keep the impeller clean and often wipe the dust and rust on the impeller.
If this dust and dirt adhere to the impeller for a long time, it is easy to cause the impeller’s dynamic balance to malfunction, and even cause the rotor to vibrate.
Therefore, dust on the fan blades should be cleaned up in time.
Maintenance of Inline Centrifugal Duct Fan Shell and Air Inlet Chamber
Regularly check the centrifugal duct fan shell and the inside of the intake chamber for obvious wear and tear, and remove the dust.
Regularly check whether the fasteners are in a tightened state.
If a compression bolt is used, be sure to compress the foot spring to an appropriate height.
Maintenance of Inline Centrifugal Duct Fan Bearings
Regularly check the bearings of the inline centrifugal duct fan and add lubricant to the bearings.
If oil leakage is found in the box, the bolts on the end cover can be tightened. If the oil still leaks, new seals need to be replaced.
Maintenance of Inline Centrifugal Duct Fan Supporting Equipment
The accessories used with inline centrifugal duct fans include motors, meters, electric actuators, etc.
The repair and maintenance knowledge of these auxiliary equipment needs to rely on the maintenance requirements of the product instruction manual.
When the inline centrifugal duct fan needs to be stored for a long time, it also needs to be maintained.
Store it in a ventilated and dry environment, rotate the rotor regularly and apply lubricating oil on the bearings to prevent rust.
Inline Centrifugal Duct Fan Installation Instructions
➫ Check the outline dimensions of inline centrifugal duct fan foundations
First, check the outer dimensions of the foundation and the center dimensions of each reserved hole.
Inline centrifugal duct fan foundation outline dimension deviation should be within ±20mm, the center dimension deviation of each reserved hole should be within ±10mm.
➫ Flatten the foundation of the inline centrifugal duct fan
Place the anchor bolts of the inline centrifugal duct fan, arrange the shim and extend the machine frame about 20mm.
➫ Rough positioning of inline centrifugal duct fan shell
Pay attention to the centrifugal duct fan installation mark, pay attention to distinguish the position of the inlet and outlet ducts, the direction of revolving of the impeller, etc.
➫ Fixed inline centrifugal duct fan
Insert the collector into the impeller of the inline centrifugal fan and fix it.
Then start to install the centrifugal fan module.
Attention should be paid to the installation that the ground bolts should be evenly stressed and the bolts should be exposed.
Then fix the lower part of the collector and the lower part of the casing with bolts, and then adjust the gap between the impeller and the bell mouth.
➫ Leveling of inline centrifugal duct fan
The verticality between the spindle and the bearing seat of centrifugal inline fans is leveled by the following method:
Stick the magnetic seal on the spindle, and point the head of the dial indicator to the processing surface of the upper-end cover of the centrifugal duct fan.
Then rotate the spindle of the centrifugal duct fan one turn, observe the dial indicator reading, and the reading is no more than 0.15mm.
➫ Inline centrifugal duct fan motor leveling
Adjust the coaxiality between centrifugal inline fans and the motor spindle. Use multiple dial indicators to align.
Every time the duct fan axis is rotated 90 degrees, the data is recorded once, and the readings of the top, bottom, left and right are measured, and the coaxial is adjusted according to the readings to make the error ≤0.05mm.
➫ inline centrifugal duct fan connecting bolt
After aligning the inline centrifugal duct fan, install the fan housing buckle cover, current collector, and cabinet.
The asbestos rope should be placed between the two cabinets.
Tighten the connecting bolts, the four-side bolts should be uniform pressure;
Take the duct fan impeller as the benchmark, and adjust the gap between the duct fan impeller and flapper again.
