What is the working principle of a two-stage series Roots blower?
? ? When we talk aboutDouble stage series Roots blowerYou must first understand the ordinarySingle stage Roots blowerWhen the gas passes through a single-stage Roots blower, it is only pressurized in one Roots blower host, so the structure is relatively simple, only through one host for sexual pressurization.
? ? The composition of a two-stage series Roots blower is to connect two Roots blowers in series. After the gas is pressurized in the first blower, the pressurized gas enters the second Roots blower for secondary pressurization to achieve a high pressure state that ordinary Roots blowers cannot achieve. Generally, the pressure of medium and low-pressure Roots blowers is below 58.8kPa, and the pressure of high-pressure Roots blowers is between 58.8-98kPa. However, under the secondary pressurization of the two-stage series Roots blower, the pressure can reach around 196kPa. The two-stage series Roots blower releases more heat during secondary pressurization due to the pressure rising to a higher stage. So there is a condenser in the two-stage series Roots blower to reduce the temperature. The two-stage series Roots blower changes the structure of the Roots blower to achieve higher pressure and meet the different pressure requirements of different users.
Single stage Roots blowers are used in situations where the pressure is not high, while two-stage series Roots blowers are often used in situations where the pressure is high. For example, the sewage treatment industry.
