Air volume cubic/hour
Full pressure
Series high-pressure centrifugal ventilator is a front Curved medium-high pressure centrifugal ventilator
Uses of series high-pressure centrifugal ventilator
Widely used for high-pressure conveying of materials, air or non-corrosive, non-flammable, non-explosive and non-viscous gases. It can also be used for high-pressure forced ventilation.
Used for supporting special equipment such as forging furnaces and spray glass manufacturing.
The content of dust and hard particles in the operating environment medium is not greater than / The medium temperature generally does not exceed ℃ (the maximum does not exceed ℃)
Structural type and hot spots of high-pressure centrifugal fan
This series of fans is The single suction type has... a total of machine numbers.
Can be made into right-hand and left-hand models. View from the motor end. If the impeller rotates clockwise, it is a right-hand fan, and if it rotates counterclockwise, it is a left-hand fan.
The outlet of the fan is expressed by the outlet angle of the casing. Both left and right rotations can be made into six angles: ℃, ℃, ℃, ℃, ℃. Our company’s standard products are ℃, ℃ and three other angles. The other angles can be made according to user needs.
The impeller has been calibrated by static and dynamic balance to run smoothly and durable.
Precautions for selecting a series of high-pressure centrifugal fans
When the preparation data of the resistance of the duct system is uncertain, sufficient motor power margin should be reserved or an adjusting damper should be installed in the duct system. Otherwise, when using The motor may be overloaded and burned out.
Series High Pressure Centrifugal Ventilator Installation Guide
Before installation, check whether the impeller and casing have been damaged or deformed due to transportation. Check whether the joints are tight. Otherwise, they should be repaired before installation and use.
The air inlet and outlet of the installed fan should have sufficient strength, rigidity, stability and durability.
The fan must be installed securely and must be installed using the anchor bolt holes of the fan or motor.
It is strictly prohibited to use the air inlet and outlet flanges as installation stress-bearing parts. The weight of the air duct should be supported by additional rigid supports.
If there are elbows within twice the diameter of the wind wheel before and after the air inlet or the sudden change in the pipe section, it will cause a sharp increase in pipe resistance and should be avoided as much as possible.
The power supply must ensure that the three-phase balance is intact and equal. The voltage can fluctuate within % of the rated voltage.
Motor wiring must be done by professionals to ensure correct wiring.
During installation, the fatal damage caused by debris entering the fan should be considered and corresponding protective parts should be installed.
It is best to add air volume adjustment valves in the pipe network system to adjust the fan operating point.
Usage, maintenance and precautions for high-pressure diagonal flow centrifugal fans
Before using the fan, you should first check whether there are any objects in the fan and pipes that hinder the rotation.
Before using the fan officially, it is necessary to conduct a test run and confirm the following items
The wiring is correct. B fan has no abnormal noise. The power is not overloaded
The fan rotation direction is the same as marked. The test machine cannot be fully opened for more than 1 minute.
The fan cannot be used with the air inlet and outlet fully open and the ducts are not connected. Otherwise, the motor will be burned due to overload.
The transported gas
No viscous substances are allowed.
The dust and hard particles contained in the medium cannot be larger than /.
The fan cannot be started and stopped too frequently, otherwise the motor may be burned.
Do not let debris block the air inlet and outlet of the motor cooling fan and the heat dissipation teeth on the surface of the motor to prevent the motor from burning due to poor heat dissipation of the motor.
Regularly clean the dust and oil on the surface of the wind wheel to prevent the dynamic balance of the wind wheel from being damaged and causing increased vibration.
