A rotary blower is a type of positive displacement pump that functions as a pump by rotating a rotor eccentrically mounted inside a casing.
Roots blowers are similar to rotary blower in that they function as pumps by rotating a cocoon-shaped root, but there is basically a gap between the roots and the casing, so a high compression ratio cannot be obtained.
However, rotary blower have a higher compression ratio than Roots blowers because there is basically no gap between the rotary blower and the casing.
Because rotary blowers can discharge large volumes of gas at high pressure, they are often used as blowers for aeration tanks in septic tanks and wastewater treatment facilities, where large volumes of air are required.
They are also used as pneumatic conveying blowers for the same reason.
They can also be used as vacuum pumps because of the contact between the rotor and casing. Today, it can also be used for suction-type filtration equipment and as a vacuum pump for vacuum equipment and suction-type pneumatic conveying.
In addition, rotary blowers are also used for mixing mixtures of mixtures and in various chemical industries.
Rotary blowers have an eccentric rotor mounted inside a casing. The rotor has a cylinder attached to it that moves up and down, maintaining contact with the rotor by moving up and down as it rotates.
Because of this structure, rotary blowers are able to maintain a high compression ratio at all times, thus producing high pressure. Likewise, they can also demonstrate high performance as vacuum pumps.
However, since there are inevitably parts that come into contact with the pump, it is necessary to constantly supply oil to the inside of the pump for lubrication.
Therefore, a mechanism to separate the oil at the discharge side was necessary, and it could not be used for equipment for which the presence of oil might be hazardous.
However, oil-free rotary blowers are now available, so they can be used in facilities that do not tolerate oil. There are also rotary blowers that support special specifications for internal coating, etc., so they are used in many industries, including the chemical industry.
