Stainless steel Roots blower

The casing of the Longgu stainless steel Roots blower is made of stainless steel material and has the same structure as ordinary Roots blowers. It has the characteristics of high hardness, corrosion resistance, non rusting, and good thermal expansion coefficient. It is mainly used for transporting high-temperature gases such as steam, and is often made of materials such as 304 stainless steel, 306 stainless steel, 301 stainless steel, 2205 stainless steel, etc. It has a wide range of applications, good quality, and long service life. The Longgu high-temperature and high-pressure stainless steel Roots blower is manufactured using food grade stainless steel production and processing. It not only has good high-temperature and high-pressure resistance performance, but also has low material wear and can be used in high-quality working environments such as grain conveying and flour conveying.

Fan characteristics

Stainless steel Roots blowers all use three bladed linear impellers, with smooth inlet and outlet pulsation and low noise. The whole machine has a compact structure and a beautiful and elegant appearance. Then let's talk about the differences between stainless steel Roots blowers and ordinary Roots blowers:

1. Stainless steel Roots blowers have different anti-corrosion capabilities

Roots blowers made of stainless steel have strong corrosion resistance, such as when conveying acidic gases such as carbon dioxide, hydrogen sulfide, and chlorine gas. There are also alkaline gases such as ammonia. When transporting these gases, stainless steel Roots blowers must be used, and it is not advisable to use general cast iron Roots blowers.

2. The cleanliness of the output gas of stainless steel Roots blowers varies

Roots blowers used in the food industry require that the output gas must be 100% clean, such as in the sugar and milk powder industries. The stainless steel Roots blower is used, and during the operation of the blower, no micro particles are generated and discharged with the gas, while the cast iron Roots blower will more or less produce micro particle wear and be mixed into the food after the gas is discharged. Therefore, it is best to use stainless steel material in the food industry.

3. Stainless steel Roots blower prices vary

The cost of stainless steel Roots blowers is relatively high, and the products produced with expensive raw materials will naturally be more expensive, generally three times higher than cast iron. Moreover, the production process of stainless steel material is very difficult because the material properties are very sticky. Taking into account two factors, the price of stainless steel Roots blowers is at least several times higher than that of cast iron Roots blowers.

4. Stainless steel Roots blower with different hardness

The hardness of stainless steel Roots blowers is higher, and cast iron materials are easier to process during machining.

5. Thermal expansion coefficient of stainless steel Roots blower

When stainless steel Roots blowers are used to transport steam, temperature is a factor that must be considered because the thermal expansion coefficient of fans made of different materials is different. There is a significant difference in the thermal expansion coefficient between fans made of cast iron and stainless steel.

Fan material

Dragon drum stainless steel Roots blower can be made of many materials, and the processing material can be flexibly selected according to customer needs.

1. 304 stainless steel Roots blower

304 stainless steel is a universal model on the market, with strong corrosion resistance and good strength.

2. 316 stainless steel Roots blower

316 stainless steel Roots can be used in the food industry and surgical equipment, and are widely used in the food industry. Many food processing companies use Roots blowers with this grade of stainless steel.

3. 301 stainless steel Roots blower

301 stainless steel Roots blower has a higher carbon content and hardness than 304 stainless steel, with higher strength and higher processing difficulty.

4. 2205 stainless steel Roots blower

The 2205 rated Roots blower has high strength, good impact toughness, and excellent overall and local stress corrosion resistance. It is widely used in the paper industry and sewage treatment systems.

Will stainless steel Roots blowers not rust?

Stainless steel Roots blowers are not rust resistant, but have stronger rust resistance, which is what we refer to as stainless steel. Stainless steel Roots blowers can achieve good corrosion resistance in dry environments, with strong corrosion resistance. If we install a stainless steel Roots blower at the seaside in an environment containing acid, alkali, and salt, stainless steel will also rust.

Is the corrosion resistance of stainless steel Roots blowers the same?

Here we need to know that different stainless steel models have different corrosion resistance abilities, such as 304 stainless steel and 316 stainless steel. 316 stainless steel has a stronger corrosion resistance ability, so the corrosion resistance of stainless steel negative pressure Roots blowers is also affected by the stainless steel model.

Introduction to the Performance of Stainless Steel Fans

Will the stainless steel Roots blower rust when damaged by external forces?

Stainless steel has the ability to resist corrosion by forming a thin, strong, and stable chromium rich oxide film (protective film) on its surface, which prevents the further infiltration and oxidation of oxygen atoms. Once for some reason, this thin film is continuously damaged, oxygen atoms in air or liquid will continuously infiltrate, or iron atoms in metal will continuously separate, forming loose iron oxide, and the metal surface will also be continuously corroded.

What is the electrochemical corrosion of stainless steel Roots blower?

Chemical reactions are happening around us all the time, and the same goes for Roots blowers. Stainless steel Roots blowers may rust or corrode due to electrochemical reactions. The surface of stainless steel may accumulate dust or foreign metal particles containing other metal elements

The attachment of particles, in humid air, forms a micro battery with condensed water between the attachment and stainless steel, triggering an electrochemical reaction that damages the protective film, known as electrochemical corrosion

Will the corrosiveness of organic juice corrode stainless steel fans?

As we mentioned earlier, stainless steel can be corroded by acid, alkali, and salt. Therefore, anything containing acid, alkali, and salt can cause rusting of stainless steel Roots blowers, such as organic acids and phlegm in vegetables, fruits, and vegetables. Therefore, it is necessary to pay attention to the hygiene of stainless steel blowers in daily life.

The corrosiveness of air pollutants

In heavily polluted areas, the air contains acidic substances, and in some places there may even be acid rain, which is corrosive to stainless steel. Therefore, the acidic and alkaline components in the air are also a form of damage to stainless steel fans. Introduction to corrosion-resistant Roots blower

How should stainless steel fans be protected against corrosion?

Stainless steel anti-corrosion requires ensuring that the stainless steel Roots blower is not damaged by external forces. Secondly, it is necessary to ensure the cleanliness and tidiness of the stainless steel Roots blower. Lastly, and most importantly, according to our national standard, the minimum grade for stainless steel is 304. If this standard cannot be met, the corrosion resistance needs to be tested, so the material is also very important.
