Roots blower The price varies from high to low, and the materials selected for each part are different. Now let's take the materials used for the casing and impeller of Roots blower as an example to explain why we choose the processing materials of cast iron Roots blower in the market: cast iron, stainless steel, carbon steel, etc. There are many products made of these materials in the market Why do you use cast iron for casing processing? Give a brief introduction to the reasons. You can make a simple reference.
1. Low processing difficulty coefficient
Compared with stainless steel and carbon steel, the processing difficulty of cast iron is relatively low. The cast iron can be fine processed with ordinary machine tools, and the results are also good, with low processing difficulty coefficient.
2. Wide market demand
There is a wide demand for cast iron roots blowers in the market. Generally, companies delivering clean air will choose cast iron roots blowers, which are cheap and can fully meet the engineering needs. Therefore, there is a wide demand for cast iron blowers in the market. Generally, enterprises will produce and sell products based on the market. Roots blower has a large market
3. Low comprehensive cost Compared with cast iron and stainless steel, the comprehensive cost of cast iron Roots blower is relatively low. For the fledgling blower enterprises, the best choice is to use cast iron for production and processing. Even if it is made of cast iron, the cost is different, which is why some manufacturers sell their cast iron blowers more expensive, while some manufacturers sell their blowers cheaper. The cast iron material will affect the overall price of the fan. The stainless steel Roots blower costs more, which is generally three times higher than that of cast iron, and it is very difficult to make stainless steel, Because the material properties are very sticky. Considering the two factors, the price of finished stainless steel roots blower is at least 4-5 times higher than that of cast iron roots blower. In terms of price and cost, Roots blower is expensive, which is also a common phenomenon in the market.
4. Under what circumstances should stainless steel be used?
If the conveying medium contains corrosive components and Roots blower is the best choice, then Roots blower made of stainless steel will be selected, and the corrosion resistance of stainless steel blower is higher than that of cast iron.
