Frequently asked questions about the use of withdrawable ventilators

Some problems may arise during the use of the withdrawable ventilator. What troubles will occur with the withdrawable ventilator during use? The experts of Instrument World World Network below will introduce the common problems and treatment methods of extracting ventilators.

The wear resistance and wear-resistance treatment of withdrawable ventilators: Because a large number of ventilators are used for ventilation and dust removal in factories, mines, tunnels, etc., the impellers and casings of fans have different degrees of wear, and direct wear in some places. Affecting the smooth progress of production, there is a high demand for the wear resistance of the fan.

Commonly used wear-resisting treatments include surfacing, spraying, spray welding, and coating of high-molecular wear-resistant materials, which can relatively prolong the service life of the ventilator.

In recent years, China has introduced an effective wear-resistant treatment method from abroad, that is, it is pasted on the surface of the impeller or volute, or embedded with wear-resistant ceramics. Because wear-resistant ceramics have good wear resistance, the wear resistance of the extension can be greatly improved. . The ventilator with a wear-resistant ceramic sheet is easy to maintain, so it has been widely used in the related industries in China.

Exhaust fan wear and tear failures are more use of polymer wear-resistant materials, mostly refers to polymer composite materials, mainly used for repair of fan drive parts wear, because the material has a stronger adhesion and compressive strength, The equipment can be dismantled and free from machining repair, which is more advantageous than the traditional methods, avoiding the thermal stress of surfacing and the disadvantages of high spraying technical requirements.

At the same time, the polymer composite material has the concession of lack of metal, it can well absorb the impact vibration of the ventilator, avoid the secondary wear, and gradually mature in the application of solving the wear failure of the ventilator drive position.

The above is the introduction of the common problems in the use of draw-out fans and the treatment methods. Everyone should try their best to avoid failures during the use of draw-out fans.
