Operational Principle

Two rotors driven by a pair of synchronizer gear, rotating at a constant speed in reversal direction, with help of insulation between suction chamber and discharge chamber supplied by a proper working gap between both impellers and between impeller and casing, then push the internal gas so as to realize functioning of exhausting.

Configuration

Rotors: compose of shaft, impeller, bearing, synchronizer gear, coupling, shaft collar, etc.

Impeller: involute type; high volume efficiency

Bearing: Double-row angular-contact ball bearings for Model 3000;

        And single-row radial short cylindrical roller bearings for Model 32000 can be 

        adapt to axial shift of rotors caused by thermal expansion.

Synchronizer gear: compose of gear ring and gear hub for easily adjust the working gap.

Casing: compose of cabinet, right and left wall-plate, on which there’re bearing pedestal, sealing parts and etc. They are in common use.

Base: Common bases for middle and small blowers and only bases for large blowers.

Lubrication: immersion for gearwheel and splash lubrication for bearings.

Driving Method: flexible coupling is an important part in it and has the function of impact alleviating and compensation to axial-deviation.

Features

Roots blowers, classified into category of positive displacement rotary one are typically characterized by following features in practical operation:

(1)   Flow fluctuating slightly while pressure is varied within allowable range.

(2)   A wide range for selecting pressure.

(3)   Transmitted air is free from oil.

(4)   Simple configuration.

(5)   Easy maintenance.

(6)   Long service life.

(7)   Slightly vibration.
