Kehuida multi-wing centrifugal fans adopt a centrifugal structure and have the advantages of low power consumption, high air volume, high noise, low appearance, durability and durability. Wide range of uses and strong adaptability. The transported medium is air or other non-self-igniting gases that are harmless to the human body. The medium does not contain viscous substances. The temperature, dust and hardness of the particles are not greater than / product application range
Kehuida multi-wing centrifuge The fan is widely used in kitchens to extract oil fume or ventilation in public places such as canteens, hotels, restaurants, etc. It is also suitable for use in production equipment such as grain machinery, chemical machinery, plastic machinery, etc.
The multi-wing centrifugal fan is a fan designed and produced by our company to adapt to the growing needs of the purification industry and environmental protection and noise reduction. The multi-objective optimization design method of various aerodynamic parameters such as noise efficiency is used in the design to achieve the overall design. Matching the best performance of the machine. With good aerodynamic performance, the impeller and pulley have been strictly corrected for static and dynamic balance.
Features: Smooth operation, low air volume, large vibration, low vibration, long life and other characteristics.
Usage
Multi-wing centrifugal fans are widely used in kitchen exhaust and range fume extraction in public places such as units, canteens, hotels, restaurants, etc. Or for ventilation and ventilation, and is suitable for use in grain machinery, chemical machinery, plastic machinery and other production equipment. It has a wide range of uses and strong adaptability.
The medium transported by the environment is air or other non-self-igniting gases that are harmless to the human body. The medium does not contain viscous substances, the temperature, dust and hardness of the particles are not greater than //.

Installation, debugging and operation of the fan
Installation, debugging and operation of the fan must be performed during the installation and operation process Note
. On some joint surfaces. To prevent rust. Reduce disassembly difficulties. It should be coated with grease or oil.
． Check that there are no tools or debris that have fallen into or left inside the casing and other casings.
． Install according to the location and dimensions shown in the drawing. In order to obtain high efficiency, the gap size between the air inlet and the impeller must be ensured.
． Ensure the horizontal position of the spindle and measure the concentricity between the spindle and the motor shaft and the non-parallelism of the two end surfaces of the coupling. The tolerance of non-parallelism between two axes is . The tolerance of non-parallelism of both end surfaces of coupling is .
When installing the regulating door, be careful not to install it backwards and ensure that the air inlet direction is consistent with the impeller rotation direction.
.The fan should be installed in the liver. Turn the rotor. Whether the elm box is too tight or scratched against the ringing part.
． When installing the fan inlet and outlet ducts, weight should not be added to the casing.
Fan operation
. Check the gap size of each part of the fan for scratches on the rotating part and the fixed part.
.Click the car to check whether the impeller rotation direction rq is consistent with the sign. Whether all wiring instruments display normal. Are there any abnormal phenomena such as water leakage, electricity leakage, oil leakage, odor, noise, vibration, looseness, etc. If there is any trouble, these should be eliminated.
.Check whether the bearing oil is between the highest and lowest oil level.
. Close the adjustment and if the operation is in good condition, then switch to full load (specified full pressure and flow) operation
. The operation at full load shall not be less than an hour for newly installed fans and not less than half an hour for repaired fans.
． After the fan starts, gradually open the adjusting door. Directly to normal working conditions. During operation, the temperature rise of the bearing shall not exceed the ambient temperature. The root mean square vibration speed value of the bearing part shall not be greater than /.
. Emergency stop is necessary under the following circumstances ① The fan is found to make severe noise ② The temperature of the bearing rises sharply ⑨ The fan undergoes severe vibration and impact
