3 Lobe Roots Blower,
pneumatic conveying blower
1 BK Type Roots Blower Main Advantage
Optimized lobe curve is adopted for reducing blower's internal leakage, improving blower's efficiency and
reducing running temperature.
After radius-center distance ratio narrowed and shaft's diameter enlarged, no deformation and collision
will occur under higher load pressure as the blower's strength is improved.
Special hollow design of end-cover is used for making bearing cavity separated from gas chamber
relatively,by which reduces the impact of inside high temperature gas on bearing cavity and lowers the
Deep groove ball bearing of high precision and low friction factor is selected for lowering operation noise.
In addition, because of larger size bearing matched for enlarged shaft diameter, the bearing's load capacity
is enhanced and its sevice life is extended.
2 Blower Working Principle
Roots blower is acubage 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 discharging air. Compared with two
lobes blower, it is of less air pulses, smaller load change, higher strength, lower noise and vibration.
Two parallel shafts have three lobes each, all the lobes keep small clearance with each other and
housing inside. Every lobes rotation, a certain air will be absorbed at inlet and transferred from the housing
inside surface to blower's discharge 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 characteristics: Simply configuration; running
smoothly; good performance stabilization. It has been widely applied in various industries.
