About BKW

Roots blower is a kind of positive displacement pumps. The impellers, which keep a film-thin clearance between each other, rotate in the casing without contacting each other to transfer the gas from the suction end to the discharge end through the inner periphery of the casing.

BKW seires Roots Blower inherits most components from BK series, it adopts water cooling in bearing cover, which can reduce the temperature of bearing when working and prolong the longevity, also it has a larger pressure capability.

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.
