DN200 BKW9020S Roots Blower Water Cooling
BKW9020S Roots Blower inherits most components from BK9020, it adopts water cooling in bearing cover, which can reduce the temperature of bearing when working and prolong the longevity, it's bore size is DN250, which can generate larger capacity suitable for cement factory and power plant use.
Tri-lobe technology means blowers have lobe tips exposed to 120 degrees around the rotor instead of 180 degrees as in a bi-lobe blower. This provides a stiffer rotor set, meaning less deflection at any load.
1. Helical type timing gears for smooth operation
2. Compact, flexibility in installation gives users more choices.
3. Integral structure of impeller and shaft for more stable and smooth operation
4. Adopt imported oil seals made from fluoric rubber with great wear resistance and high-temperature resistance.
5. Low noise, low vibration and energy consumption.

Working Principle
Roots blower is a cubage blower, and it discharges a fixed amount of air in proportion to its rotation speed. Every rotation, there is two lobes to finish three times absorbing and dischargeing air. Compared with two lobes blower, it is of less air pulses, smaller load change, higher strength, lower noise and vibration.
Two paraller shafts have three lobes each, all the lobes keep small clearance with each other and housing inside. Every lobes rotatiomn, a certain air will be absorbed at inlet and transfeered form the housing inside surface to blower's diacharge port.
Two shafts will be turned by the timing gears, no any touching between lobes, so it can be turned at high speed without any lubrication inside. It has the following chaaracteristics: simply configuration; running smoothly;good performance stabilization. It has been widely applied in various industries.
Cooling Water:
Clean water without foreign materials is required.
Water temperature shall be less than 40 ℃.
