Description of blower parts:

Casing	Made of Casting iron HT200 ENDLESS structure adopted for improving efficiency, one-time machined by CNC center with high precision
Rotor (Shaft and impeller)	Made of Casting iron QT500 The impeller and shaft is cast as an integral part. Adopting NC planer for machining to achieve high precision
Gear end bearing	Made of GCr15 NSK brand, double-row angular contact ball bearing, capable of supporting axial load
Drive end bearing	Made of GCr15 NSK brand, cylindrical roller bearing
Gear	Made of 20CrMnTi Bevel structure for more smoothly running
Oil seal	Made of fluoro rubber bears high temperature and has a longer life.

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.
