Exhaust:0.7-1.0MPa
Drive mode:弹性直联
Cooling method:风冷

Air end:

· Compressor Housing Has A Pair Of Precision Machining Of The Yin, Yang Rotor (Yin And Yang Rotor Does Not Touch).

The Motor Drives The Male Rotor Through The Transmission Device, And Then The Synchronous Rotor Of The Other End Of The Male Rotor Drives The Female Rotor Synchronous Gear So That The Yin And Yang Rotor Can Keep The Synchronous Rotation In A Certain Gap.

· The Air Entering The Compressor Chamber Is Effectively Compressed In The Crossover.

· Shell With Sandwich, So That Water Or Oil And Other Cooling Medium Through The Sandwich To Reduce The Temperature Of The Gas Inside The Shell.

Compressor Gears And Bearings Are Lubricated With Special Lubricants.

· The Oil Seal Inside The Main Body Prevents The Lubricating Oil In The Bearing Cavity From Entering The Compression Chamber, Ensuring That The Output Air Is Absolutely Free Of Oil And The Gas Seal Prevents The Air From Leaking Out Of The Compression Chamber.

Motor:

· The Frame And The End Cap Of The Motor Are Made Of Cast Iron Material So That The Gap Between The Rotor And The Spindle Is Uniform;

· Design Speed, Torque And Operating Parameters To Meet The Compressor Load Requirements;

· Designed With SKF Heavy-Duty Bearings, Greatly Increasing The Stability And Life Of The Motor;

· High-Efficiency Motor With F-Class Insulation, B-Class Temperature Rise, Longer Life, More Able To Adapt To Harsh Environments;

· The Motor Adopts The IP55 Degree Of Protection Of The Motor, Effectively Prevent Dust And Water Into The Motor;
