The SRB three-lobe roots blower is a type of positive displacement blower. Two sets of impellers rotating in opposite directions are arranged inside the casing. Between these two sets of impellers, and between the impeller and the casing, it operates under a state where there is only a small gap when rotated. When the impeller passes through the suction end, a certain amount of air is captured between the impeller and the casing. The air is moved sideways as the impeller rotates, so the pressure rises gradually, and sent to the outlet end.
Because the blower is installed under water, the operating noises reaching the surface of water are refracted into water instead of air. Meanwhile, water and tank walls also refract the noises intowater.
In this way, noises are effectively reduced. SRB series will be applied to school, building, community and hospital.
SRB series are not necessary to fix on foundation, saving piping cost. Being installed under water, so there is no need to add a soundproofing cover or build a soundproofing factory. Besides,since it is installed in a water tank, it doesn’t occupy space. The work place can be utilized more efficiently.
It is not necessary for belt and pully because SRB series design directly drive system for raising high efficiency and reducing failure factor.
Using squirrel-cage induction motor, with F class insulation and IP68 motor protection grade. Build-in leakage detector in motor, can pervert the motor from burning out, overload & overheating.
Dry type. It won’t distort even by sudden pressure rise or absorption force. The area of filtration device is 1.2 times than the capacity of blowers. It can control the pressure loss less than 25mmAq.
