      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.

      Reasons for excessive Roots blower pressure:

      1. The pressure of sewage aeration roots blower depends on the resistance it receives, as long as it can withstand the pressure range, it can work normally. For example, in a pond with a depth of 2 meters, the pressure of the air blown by a Tianjin ventilator is 20 kPa. At a depth of 3 meters, the pond becomes 30 kPa. As long as the motor output power can reach the load.

      2. If the pressure displayed by the pressure gauge is greater than the pressure that should be output, it may be caused by blocked pipes, blocked aeration heads, etc.

      Roots fan causes large motor current:

      1. Compared with the specified pressure, the pressure difference is large, that is, the back pressure or the inlet pressure is high.

      2. Compared with the flow required by the equipment, the fan flow is too large, which increases the pressure.

      3. The inlet filter is blocked and the outlet pipe is blocked or blocked.

      4. The rotating parts collide and rub (stuck).

      Solutions to excessive Roots blower pressure:

      1. Reduce the pressure to the specified value.

      2. Put excess gas into the atmosphere or reduce the speed of the blower.

      3. Remove obstacles.

      4. Stop the machine immediately and check the reason.

      5. Adjust the oil level to the correct position.

      6. Check the belt tension and replace it with a large diameter pulley.

      How does Roots blower distinguish high pressure and low pressure?

      1. The pressure is lower than 58.8kpa, including 58.8kpa

      Below this pressure, above 9.8kpa, it is called low-pressure trilobal roots blower. Low-pressure trilobal roots blower is air-cooled. Low-pressure trilobal roots blower is usually single fuel tank. Certainly different.

      2.Pressure is 58.8 to 98kpa

      It is called a high-pressure roots blower. The high-pressure roots blower is a double fuel tank series. Under this pressure, water cooling is required. This is to ensure that various accessories can work normally.

      For water cooling, high-pressure roots blowers can also be air-cooled.

      3. Above 98kpa

      Above 98kpa also belongs to the series of high-pressure roots blowers. Due to the high pressure, a two-stage booster is required. The structure of the two-stage booster roots blower is different from the ordinary.
