      Wear and treatment of tunnel fan impellers

      Wear of impeller

      After the fan impeller rotates, a small amount of large particles and many tiny dust particles can be passed through the induced draft fan together with the high temperature and high speed smoke, causing the blade to be continuously washed. In the long run, blade-like wear is formed at the blade exit. Because this wear is irregular, it causes imbalance in the impeller. In addition, the surface of the impeller is easily oxidized at high temperatures, forming a thick oxide scale. The binding force of these oxide scales to the surface of the impeller is not uniform, and some oxide scales will fall off automatically under the action of vibration or centrifugal force, which is also a cause of the imbalance of the impeller.

      2. Fouling of the impeller

      The humidity of the flue gas in the tunnel construction tunnel is very high. Although the dust particles that have not been cleaned are small, they have a high viscosity. When they pass through the induced wind, they will be adsorbed on the non-working surface of the blade under the action of the gas vortex, especially at the inlet and outlet of the non-working surface, which will form more serious dust fouling, and gradually thicken. When part of the dust falls off under the combined effect of centrifugal force and vibration, the balance of the impeller is destroyed, and the entire induced fan will vibrate.

      2, countermeasures to resolve the imbalance of the impeller:

      1. The method of solving the impeller wear, in addition to improving the ventilation effect of the fan, is to improve the anti-wear ability of the impeller.

      At present, the more mature method in this regard is that the impeller is precision-casted, added with anti-wear metal elements, and then through thermal spraying technology, that is, special methods to change the wear-resistant and high-temperature resistant metals or ceramics into high-temperature, High-speed particle flow is sprayed onto the surface of the impeller blades, forming a layer of tough outerwear that is much more resistant to abrasion, high temperature and chemical properties than the impeller itself. This can not only reduce the damage caused by the impeller's dynamic balance, but also reduce the imbalance caused by the oxide layer.



      Performance characteristics of full wind blower:

      1.Easy installation

      Full-wind high-pressure blowers can be installed in the use place at any time for compressed air or for evacuation. And can be installed horizontally or vertically.

      2.Sturdy structure

      The full wind high pressure blower body is made of ADC12 aluminum alloy, which is different from the general iron shell or AC10 aluminum alloy blower. The ADC12 material is the same material as the Mercedes-Benz car wheel drum, which is more durable.

      3.High reliability

      Except for the impeller, the full-wind high-pressure fan has no other moving parts, and the impeller is directly connected to the motor without gears or transmission belts, so it has high reliability and is almost maintenance-free.

      No oil, gas and pollution. When the impeller rotates, there is no contact with anything, no lubrication, so no oil and gas can be guaranteed.

      4.Low vibration

      Full-wind high-pressure blower parts are imported from Germany and Japan. Processing and testing equipment are used. The parts of the running part have been designed with extremely precise balance. The vibration rate is very low due to testing and correction.

      5.Low noise

      The full-wind high-pressure fan is directly driven by a high-pressure low-noise motor, and there is a built-in silencer at the entrance and exit, which can reduce noise during operation.

      Features:

      1. High pressure, large air volume, low noise and light weight.

      2. The use of aluminum alloy material significantly reduces weight and achieves the purpose of weight reduction.

      3. The motor is designed by IEC (the motor adopts IP55 standard, the insulation level is F or H, with 3C, CE certification.), Fully closed outer fan aluminum frame motor, special shaft design, Tianjin ventilator factory , suitable for long-term use .

      4. A multi-stage impeller is used to make the surrounding gas rotate in a spiral direction to achieve a supercharging effect. The impeller uses a special balance correction to reduce vibration. Special blade design, high pressure, large air volume, low noise and long life.

      5. Special air volume adjustment damper, high air volume control stability, easy operation (applicable to CX.TB.HTB).

      Complete styles, large stocks, and fast delivery.



      Precautions for long-term blower shutdown

      In the winter, there are fewer occasions for using Tianjin blowers . If we stop for a long time, we need to pay attention to some problems. Let ’s introduce the precautions for long-term shutdown of the blowers. First of all, we need to prevent the rust oil before stopping. Add to avoid rust or corrosion problems in the flagship storage. The cooling water in the bearing box needs to be released to avoid freezing and cracking due to the low temperature in winter.

      There are some electrical components inside the blower. If these components are wet, they will definitely be affected. In order to avoid moisture, we recommend that you install them in a dry and ventilated environment. Rubber vulcanizer manufacturers recommend that you regularly The machine is started once a week to prevent the main shaft from deforming and bending under long-term static conditions. Periodic maintenance and maintenance are also necessary under long-term storage, which can extend its service life and avoid recurring Failure during use.
