Tri Lobe Blower

1 Roots blower is a kind of positive displacement blower, through a pair of rotors' mesh '(there are gaps between the rotor, and don't touch each other) makes the air inlet is separated, the rotor by a pair of synchronous gear drive, do the reverse direction, no inner compression from the suction gas suction mouth to vent.The gas reaches the vent and is pressurized to complete the gas delivery due to the backflow of the high-pressure gas in the exhaust side.

Roots blower old, regardless of the lobes, trilobites, rotor outlet to the front line to open at the top of the moment, the air outlet of high-pressure compressed air flow within a chassis, resulting in a dramatic pressure change, formed the fan noise.The fan has studied the spiral shape to eliminate this factor.

Key points of spiral shape.

A rotor: the entire rotor width of the inlet side is open and begins to close.The exhaust side is in a loop open and is more than half open.

B rotor: the inlet side is in a loop close and close to complete closure.The exhaust side is not open but will open.

A rotor: the inlet side of the inlet is in A more closed position, and the triangular hole shown in the oblique line is closed in the case of the enclosure.The exhaust side is in a state of exhaust.

B rotor: the inlet side is on the verge of reaching the shell screen.The wind side is in the exhaust process, the triangular hole opens the state.

A rotor: the inlet and exhaust side are closed, but the exhaust side is on the verge of opening.

B rotor: the inlet side has just entered a closed stroke and is in a closed state. The exhaust side has been opened in a gradual way and will be fully open.
