Abstract

The high pressure Roots blower includes one cylinder with airflow inlet, airflow outlet and inside air cavity; one outer cover with one or several cooling air inlets and one or several cooling air outlets for cooling air to pass through; one space between the cylinder and the outer cover; one or several centrifugal cooling fans mounted onto the rotor shaft and near the inlet and outlet on the outer cover; two sealing layers on the tri-blade rotor to reduce internal leakage and casual mechanical contact; one pressure reducing safety valve mounted on the cylinder to relief too high pressure automatically while sound audible warning signal; and one high pressure outlet flange with raised sealing surface. The high pressure Roots blower of the present invention can obtain high pressure rise and pressure ratio, less temperature raise and internal leakage caused by high pressure, raised efficiency and raised reliability.

Description

technical field [0001] The present invention relates to the technical field of mechanical blowers used in various industrial applications, and belongs to double-rotor vane blowers, commonly known as Roots blowers. Background technique [0002] Roots blowers are widely used in various industrial applications. In the language of the blower, compared with the traditional medium pressure (the pressure is 0.35 ~ 1.05kg / cm 2 = 5-15 pounds per square inch), 1.05 ~ 1.76kg / cm 2 (=15-25 psig) pressures are commonly referred to as high pressures. Examples of applications for Roots blowers with high pressure capability are: deep tank aeration tanks used in modern sewage treatment plants, pneumatic conveying of thin or dense phase dispersions, or as a vacuum power source. [0003] However, 1.05~1.76kg / cm 2 (=15-25 psi) pressure, which is usually difficult to obtain in one-stage compression, mainly due to the temperature rise corresponding to the compression ratio and internal leakage...
