Do you know what the knowledge of high-pressure Roots blower is? Now let's introduce the detailed knowledge of Roots blower.

The high-pressure Roots blower was invented by British George Kings in 1849. Later, it was improved and promoted by the American Roots Brother, and gradually became widely known and applied. Because the Roots brothers applied for the trademark "Roots", European and American countries also called it "Roots blower", which was translated into "Roots blower" when it was introduced into China, It is a volumetric constant flow gas conveying equipment. At the same speed, the greater the pressure difference caused by the system resistance, the greater the flow will cause the internal leakage, and the micro loss will be proportional. Therefore, when selecting the high-pressure fan, the high-pressure Roots fan with a slightly higher theoretical flow can be selected to remedy this defect;

In addition, it has the pressure holding characteristic, that is, its pressure comes from the reaction force of the system itself, which has the characteristic of forcing, so this characteristic is called "hard wind". However, the high pressure fan has another disadvantage, that is, the noise is high, especially with the increase of pressure. With the continuous improvement of the national environmental protection department's requirements for noise, It is also an inevitable problem to be solved for the development of high-pressure Roots blower.
