A professional manufacturer of three roots blowers

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

bearing temperature.

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.
