How much can the temperature of Roots blower for conveying gas not exceed?

How much can the temperature of Roots blower for conveying gas not exceed? The medium conveyed by Roots blower is clean air, and it can also convey coal gas, marsh gas, natural gas, etc., but it cannot convey toxic or corrosive gas, and then explosive gas, such as hydrogen. Although Roots blower can carry out special sealing to achieve zero leakage, hydrogen gas is explosive, flammable, and very unstable, Few manufacturers are willing to make Roots blower for hydrogen transportation. Roots blower not only has requirements for conveying medium, but also has requirements for conveying gas temperature. If the temperature is generally higher than 40 ℃, the Roots blower will not be able to deliver, which will cause many problems. Let's take a detailed look.

1. Why can't the temperature exceed 40 ℃

When the roots blower compresses the gas, it will produce some heat. This heat, together with the temperature of the gas itself, is the temperature at the outlet of the roots blower. If the gas temperature of the roots blower exceeds 40 degrees Celsius, the outlet temperature will be too high, causing damage to other accessories, such as lubricating oil failure, bearing failure, etc., which is fatal to the roots blower.

The calculation method of other outlet temperatures of Roots blower: inlet air temperature+inlet and outlet pressure difference. This is only a rough calculation, not a * * * calculation.

2. Special treatment is required for conveying gas

The centrifugal fan can transport high temperature gas, but the roots fan cannot transport high temperature gas. When the centrifugal fan and roots fan transport such gas as gas, they need to carry out explosion-proof treatment on the fan, otherwise there will be major accidents. Because of the need for special treatment on the fan, the price of the fan transporting special gas is higher than that of the ordinary fan.

3. What are the reasons for the high temperature of Roots blower?

There are many reasons for the high temperature of Roots blower, such as fault, operation error, high inlet air temperature, which are all the reasons for the high temperature of Roots blower body. In the previous article, Jingong Fan Editor mentioned these reasons. If you are interested, you can click here to see. How is the abnormal outlet temperature of Roots blower caused?

The Roots blower produced by us can be used to transport gas, marsh gas, natural gas, etc., but the temperature needs to be controlled below 40 ℃. If the temperature is too high, it cannot be transported. If you have other problems, you can consult us at any time.
