      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.


      Tianjin Blower Group Co., Ltd. is a professional manufacturer of various fan designs and manufacturers. The company has engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality.

      The high pressure fan is the core equipment in the sewage treatment process, which directly determines its effect and energy consumption. In the biological wastewater treatment process, high-pressure fans are mainly used for aeration tanks to increase oxygen, promote the growth of aerobic microorganisms, and use their metabolism to break down suspended solids, dissolved organic matter, and nutrients such as nitrogen and phosphorus in wastewater to achieve wastewater treatment. The purpose is the core equipment of the sewage treatment plant. The performance of the fan directly affects the quality and energy consumption of sewage treatment.

      The sewage treatment industry is an important part of environmental protection and municipal public infrastructure construction, and the grill machinery in sewage treatment also requires high-pressure blowers. In the developed countries, the sewage treatment industry has matured, and the related equipment is only for renewal needs. In China, although the economy continues to grow rapidly, due to insufficient investment in the environmental protection industry, and despite the increasingly rigid requirements for the development of the industry, the compound annual growth rate of wastewater treatment facilities in China is only 3.86%. According to the National Eleventh Five-Year Plan, accelerating the construction of urban sewage treatment and water pollution prevention in key river basins has been listed as one of the ten key measures to expand domestic demand. The central government has determined that 90 billion yuan will be allocated for water pollution treatment It will drive the total investment in the sewage treatment industry to reach 280-300 billion yuan. The market for high-pressure fans is huge and the market demand is huge.

      1. Check the tightening of each part and whether the positioning pin is loose;

      2. Whether there is water leakage or oil leakage inside the Roots blower body;

      3. There must be no scale, rust and peeling inside the three-leaf roots blower body;

      4. Pay attention to whether the lubrication and cooling conditions are normal, and pay attention to the quality of lubrication. Listen frequently for noise from the blower operation. Pay attention to whether the unit is operating under non-compliant conditions;

      5. The overload of the blower is sometimes not immediately displayed. Tianjin axial flow fans, so pay attention to the increasing trend of inlet and exhaust pressure, bearing temperature and motor current, so as to determine whether the machine is operating normally;

      6. Before dismantling the machine, the Roots blower should measure the size of each machine, make a record, and mark the parts to ensure that the original cooperation requirements are maintained after assembly;

      7. The bearings and gears of the blower are splash-lubricated. It is recommended that users of N68-N150 medium pressure industrial gear oils can also choose suitable lubricants by themselves. It is necessary to ensure that the performance of the lubricants and the above-mentioned lubricants are comparable to the normal operation of gears and bearings. The amount of oil in the fuel tank must be kept at a level of 3-5mm above the center line of the oil standard when the oil is stopped (200 hours of start-up work, oil change once), and oil change every six months thereafter. Clean the fuel tank and gears with neutral kerosene before injecting new oil;

      8. Maintenance and overhaul should draw up a reasonable maintenance system according to the specific use situation, carry out on schedule and make records. It is recommended to overhaul once a year and replace the bearings and related wearing parts.

      Roots blowers have relative movement between the impeller and the impeller, and between the impeller and the body. They are in a non-contact state and must have a suitable working clearance to ensure that they have both a sealing effect and a normal operation of the fan.
