      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.

      At present, with the rapid development of the economy, various industries have also accelerated the pace of development, such as the development of cement, aquaculture, electricity, flour processing, coal industry, textiles, chemical industry and other industries. Broad market demand space. Slowly use high-pressure roots fans.

      Then the Roots blower manufacturers should remind everyone that the high-voltage Roots blower operation staff must master the common troubleshooting methods. For this reason, the chapter Chuluots blower manufacturers will introduce the failure analysis and troubleshooting methods of the high-pressure Roots blowers one after another.

      Impellers are an important part of high-pressure roots fans. Most of the roots fans currently on the market are three impellers, that is, three-leaf roots fans. These impellers usually fail:

      1. There are contamination impurities on the impeller, which causes the gap to be too small. At this time, you only need to remove the dirt, and check the internal parts for damage. If there is damage, repair or replace it in time.

      2, gear wear, causing large backlash is a common problem of high-pressure roots blowers, especially for long-time blowers, the gear wear is more serious, you need to adjust the gear clearance, if the gear backlash is greater than the average 30% ~ 50% should replace the gear.

      3. The gears of the high-pressure roots blower are not firmly fixed, and the impeller cannot be synchronized. It is necessary to reassemble the gears and maintain a taper with a contact area of 75%.

      4. Bearing wear of high-pressure roots blower can cause clearance to increase. At this time, the bearing needs to be replaced.

      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 displayed immediately, so pay attention to the increasing trend of intake and exhaust pressure, bearing temperature and motor current 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.

      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 tube curve, the pressure-flow performance curve of the fan can be changed by changing the opening and closing angle of the guide vane. For the Tianjin jet fan , the flow rate is changed by moving the operating point to a new one. The method is implemented on the fan characteristic curve.

      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.
