      Installation, use and maintenance of blowers

      1. Before installation, check the fan components, whether the casing is complete, whether the impeller and casing rotate in the same direction, whether the main components such as the impeller, main shaft, and bearings are damaged, and whether the transmission unit is flexible.

      2. Be clear of the sundries inside the cabinet during installation. When connecting the inlet and outlet ducts, adjust them to fit naturally. Do not force the connection. Do not add the weight of the pipeline to the fan components.

      3. The transmission case must be installed horizontally, otherwise bearing damage may easily occur.

      4. After the installation is complete, try to dial the transmission unit to check whether it is too tight, and whether there is any friction or collision with the fixed parts. If there is any fault, you must find out the cause and reassemble or adjust it.

      5. Before starting the fan, first confirm the flow, oil level to the oil window 1 / 2-2 / 3, blower manufacturers , (grease lubricated without oil window replenishing grease), if the fan is left for a long time, you must check whether the grease has deteriorated And replace if necessary.

      6. Close the damper and start the motor, especially for the boiler induced fan. When the furnace temperature rises, slowly open the damper until the furnace temperature rises to the normal temperature. Adjust the damper to the required air volume and always monitor the motor current. During the operation, the click current is strictly monitored, and the motor is strictly prohibited from overloading.

      7. Always check whether the bearing temperature is normal during the operation. The bearing temperature cannot be greater than 45 ° C and the surface temperature cannot exceed 80 ° C. If abnormal phenomena such as severe fan vibration, impact, and rapid rise in bearing temperature are found, the vehicle must be stopped immediately to find out why Power on after a fault.

      8. When the new fan is used for 200-250 hours, the lubricant must be replaced. Use 30 # -40 # mechanical oil in winter and 50 # oil in summer.

      9. If vibration is found during the operation of the fan, stop the machine immediately to clean up the dust and attachments attached to the impeller. If the machine still starts to vibrate after restarting, the cause must be identified and the fault should be rectified during startup (probable cause: the impeller is out of balance, Deformation and bending of main shaft, bearing damage, loose foundation fixed wheel bolt, system resonance, etc.).

      10. If the spare fan is not used for a long time, the bearing should be greased to prevent bearing corrosion. And regularly rotate the impeller by 150 ° -180 ° or use two fans alternately. Because the fan is stationary at one position for a long time, it has caused uneven ash hanging or impeller rust, resulting in imbalance.

      11. For fans with circulating water cooling, turn off the circulating water after the fan stops, and drain the accumulated water in the circulating water jacket of the transmission box to prevent rust blockage or winter damage, and remove the lubricating oil or grease inside the box. Grease to prevent bearing corrosion.

      12. Normally running fan, usually 3-4 months, change the lubricating oil or grease once. When the air temperature of the fan is high (200 ℃), the lubricating oil or grease should be replaced within 2 months. Deterioration of oil or grease will lead to accelerated bearing wear, dust, rust and other factors. It will also cause deterioration of lubricating grease and affect the normal service life of the fan.

      13. Precautions for fan maintenance work:

      (1) The fan can only be operated under normal conditions.

      (2) Turn on the fan after maintenance, and pay attention to whether all parts of the fan are normal.

      (3) Regularly remove dust, grease and impurities inside the fan.

      (4) To ensure personal safety, fan maintenance must be performed during shutdown.

      (5) Lubricating oil or grease should be replaced for each disassembly.

      Imported guide vane adjustment principle and characteristics

      The inlet guide vane adjusting device is a set of guide vanes-inlet guide vanes, which can be adjusted near the suction inlet of the blower, and its function is to make the airflow rotate before entering the impeller, causing distortion speed. The guide vane can rotate around its own axis. Each rotation of the vane means changing an installation angle of the guide vane, so that the airflow direction entering the fan impeller changes accordingly.

      Principle of air volume adjustment by inlet guide vane

      When the guide vane installation angle θ = 0 °, the guide vane has basically no effect on the inlet airflow, and the airflow will flow into the impeller blades in a radial direction. When θ> 0 °, the inlet guide vane will deflect the speed of the airflow inlet along the direction of the circumferential speed and at the same time have a certain throttling effect on the speed of the airflow inlet. This pre-spinning and throttling effect will cause the fan performance curve Down, so that the operating conditions point changes, to achieve fan flow regulation. Energy-saving principle of imported guide vane adjustment.

      When the inlet guide vane installation angle increases from θ1 = 0 ° to θ2 or θ3, the operating condition point moves from M1 to M2 or M3; the flow rate decreases from Q1 to Q2 or Q3; the shaft power decreases from P′1 to P '2 or P'3. The area shown by the hatching line is the power saved by the inlet guide vanes than the throttle adjustment. In this project, the depth of the aeration tank is fixed, and the flow rate of the blower is adjusted under the condition that the outlet pressure is kept constant, that is, when H = constant and Q = variable, the characteristic curve of the pipe network is approximate to a horizontal straight line. The blower uses an inlet guide. Blade adjustment, without the need to change the pipe curve, the pressure-flow performance curve of the fan can be changed by changing the opening and closing angle of the guide vane. The change of the flow rate is by moving the operating point to the newly changed fan characteristic curve. On the method.

      The centrifugal fan adopts the imported guide vane adjustment method, which can obtain high efficiency and a wide range of performance during partial load operation. Under the condition that the outlet pressure is kept constant, the working flow can be changed within the range of 50% to 100% of the rated flow. The greater the adjustment depth, the more power saving. If the flow rate is reduced to 60% of the rated flow rate, the imported guide vane method saves power by as much as 17% compared with the imported throttling method. In addition, its structure is relatively simple, reliable operation, convenient maintenance and management, and low initial investment. Therefore, the use of imported guide vanes to adjust the flow of the blower in this project is obviously a good adjustment method.

      How centrifugal blowers work

      The working principle of a centrifugal blower is similar to a centrifugal fan, except that the compression process of air is usually carried out by several working impellers (or several stages) under the action of centrifugal force. The blower has a rotor that rotates at a high speed. The blades on the rotor drive the air at high speed. The centrifugal force causes the air to flow in the involute-shaped casing to the fan outlet along the involute. The high-speed airflow has a certain wind pressure. The new air is replenished from the center of the case.

      The working principle of the single-stage high-speed centrifugal fan is: the prime mover rotates the impeller through the shaft at high speed. The airflow enters the high-speed rotating impeller from the axial direction of the inlet and becomes radial flow and is accelerated. Then it enters the expansion chamber, changes the flow direction and decelerates. This deceleration effect converts the kinetic energy in the high-speed rotating air flow into pressure energy (potential energy), so that the fan outlet maintains a stable pressure.
