Wear-resistant centrifugal fans can be used in thermal power plant as induced draft fan, exhaust fan, steel blast furnace fan, cement plant, kiln tail fan and other working conditions with hard particle erosion and abrasion such as ceramic industry.

Hard-wearing under extreme conditions Fans are often subject to the harshest wear. Abrasive media that is carried in the air flow (e.g. clinker dust, quartz and also corundum, wood and plastic shavings) attack the material.

Wear can render high-quality machine parts inoperative in the shortest time. The resulting costs are considerable. Investing in preventive measures is cost effective.

In order to improve the wear-resistant effect of the impeller,SIMO BLOWER uses various measures to prevent abrasion to impellers and inner casing walls through friction and impact. Such protective measures are decided on as early as during the design of our fans. Suitable materials, high-precision machining and optimal blade geometry effectively increase service life.

MEASURES:

Classified by wear-resistant fan material: titanium whining fan / wear-resistant surfacing / wear-resistant ceramics；

Classified by wear-resistant fan process: pulverized coal fan / circulation fan / sintering fan / blast furnace fan；

product feature:

1. It can output higher outlet pressure and can work in high temperature medium, suitable for any need to transport high pressure & high temperature gas industrial occasions.

2. According to customer performance requirements customized design, and optimized by CFD technology, the energy consumption is lower than similar models.

3. For the material of impeller and main spindle, we will choose high-strength carbon steel, low-alloy steel, high-temperature alloy steel, high temperature high-strength alloy steel for different working conditions temperature and working speed, so that the impeller and main spindle at high temperature still maintain reliable strength.

4. For dusty gas, we can meet all kinds of working conditions from small amount of dust to large amount of dust. After special treatment, the hardness of blade surface can reach HRC60~70, which can extend the life of the impeller by more than 3 times.

5. The moderate bonding between the components is tight, and the sealing performance is good, ensuring that the output pressure will not be reduced.

6. After annealed treatment, the internal stress of the structure generated during welding can be completely eliminated to ensure that the impeller will not creepage and crack.

7. Ultrasonic flaw detection on the welding seam and main spindle of the impeller to ensure that there are no welding defects or material defects and ensure the strength.

8. The impeller is subjected to a high standard of dynamic balancing adjusting to ensure stable operation of the fan.

9. Test assembly after production is completed to ensure that there is no interference between the components.

10. Provide on-site arrangement and guidance services.
