Features:
1. Helical type timing gears for smooth operation
2. Compact, flexibility in installation gives users more choices.
3. Integral structure of impeller superior to split structure, more
stable in power transmission
4. Adopt imported oil seals made from fluoro rubber, which is of
better wear resistance and high-temperature resistance.
5. Small vibration and economical 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.
