1 Brief introduction
BKW series 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.
2 Blower 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 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.
