BK4005 Three Lobe Roots Blower 0.42-1.8m³/min for Water Treatment
About BK Three Lobes Roots Blower
BK series roots blower, with the intergral structure of impeller and shaft, has a waide application in environmental protection, electric power, architecture, gas supply and etc.
Product Description
Roots Blower is a cub-age 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.
Main Chrarcteristics
1) Working smoothly as helical timing gears is adopted.
2) It is flexible mounting ways because of the same structure in inlet and outlet.
3) It adopts more reasonable bearing structure, which can incresase the bearing operation life.
4) It is low noise, 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.
