Goods Description
The Roots Blower are improved by raising the intensity, it helps to prevent the center rotor and axis deviation from external influences. The rotor is used with the most advanced four-Shaft method in one time process, it can reduce man-made errors, enhance the precision of the lobe wheel and promote the blower efficiency. The air compartment and the side cover of the blower have a flange and groove rim, which can not only strengthen the blower's operational functions but also prevent eccentric phenomenal resulting from the fastening of the stud, which may shorten the life of the blower. Besides, noise and vibration reduction are the main emphasis in developing the new series of roots blower.
Features
Work priniciple of roots blower
There're two rotors in the compartment of the blower body, when the rotors rotate in opposite direction, they suck air in to balance the pressure created due to the volume V1 change on the inlet side. And the air in the volume V2 will be sent out through the discharge side and the high pressure will be created through the discharge.
There's no need lubrication between two rotors because there's gap between them for no touch moves, hence no friction. The blower runs well even at high spped and supply clean air, it also can be applied for vacuum purpose.

Model selection
1. The air volume shown in above performance form, it's the suction
volume under standard suction condition (Temp. 20 ℃, absolute
pressure 1.0332 kg/c㎡, relative humidity 65%).
2. The convert formula between normal (for example: 0 ℃, 1.0332 kg/c㎡, ABS) and standard condition:
Qs=Qn * (yn/ys), y=0.465 * (P-0.378 ᵩ * Ps) / (273+t)
ᵩ=humidity (%) P=Pressure (mmHg)
Qn: air flow under normal condition N m³/min
Qs: air flow under standard condition (indicated in above performance table m³/min)
Y: air ration weight (kg/m³)
Ps: water vapor saturation pressure of the temperature (mmHg)
T: absolute temperature (273+t) ℃
3. Vice versa, an air flow under discharge condition can be converted to an air flow under standard condition:
Qs=Qd * (1.0332+Pd) * (273 +Ts) / (1.032*(273+Td))
Qd: air flow under discharge condition, m³/min
Ts: suction temperature
Td: discharge temperature
Pd: discharge pressure, kgf/㎡
4. Select blower type, diameter, rpm and shaft power based on performance table as required the air flow and discharge pressure.
5. Smaller size for economic view, and larger size for lower noise level & stabler performance for a long view.
