Rotary Screw Air Compressor Overhaul !

Rotary Twin Screw Air Compressor Overhaul;
14th April 2010
Penang, Malaysia.
Model: CompAir Broomwade N6090, imported version [ not sold locally ]

Front showing the drive coupling, behind the shaft is the gear box.










Pinion shaft of drive gear, gear box housing








Compressor case, note the size;
The bigger size hole is for male drive rotor.
The smaller size on the left is the female rotor, driven.






The end plate, note the wear on the surface on the bigger rotor.
Cause by some foreign metal particles.









Gear case housing










Driven rotor, that is the female rotor.





Drive rotor, this case is the male rotor.
The gear on the floor is mounted in the gear box to the drive shaft of the main motor, this gear will drive the smaller size gear install on one end of the male rotor shaft.

Can you afford to give away money?

Can you afford to give away money?


We will show you how to save money:

on the production of compressed air



Each compressed air station offers an enormous potential for conserving energy,

for example in the following areas:

  • Compressor capacity utilisation
  • Modern compressor technologies, e.g. speed control
  • Modern control systems
  • Efficient compressed air treatment, not too much, not too little
  • Heat utilisation, what is it "worth"?
  • Leaks: find/reduce them
  • Pressure losses: localise/prevent them
  • Correct component dimensions
    (piping, tanks, ...)
  • etc., etc.

During the one-day seminar for operators and planners of compressed air stations

we will show you


" Possible ways of producing compressed air at a reasonable price "


Practically oriented, with case studies, we make interesting suggestions, give tips and assistance regarding the correct way to handle the energy source, compressed air.



We are convinced that the costs of producing compressed air can be effectively reduced by means of minimal measures also in your case.

Are you interested?

We would be delighted if you would contact us.

Air End Overhaul --- QSI1000

Air End Overhaul:
Completed and test run in February 2010, just before Chinese Lunar New Year.


Male rotor on shaft stand, ready to repair.







You are right, Wong; too much self-discipline will discourage your playful, wandering imagination. It'll snuff out the flames of inspiration and creativity. And it'll weigh you down with routines and logic. It simply isn't "spiritual."

But, then, neither is too little.

Another view of the same Male rotor;
QSI 1000



" To swear off making mistakes is very easy. All you have to do is swear off having ideas "




Note:
The worn out Drive end bearing inner cone!





"The reality of life is that your perceptions -- Right or Wrong -- influence everything else you do. When you get a proper perspective of your perceptions, you may be surprised how many other things fall into place."

Another view of the male rotor



Focus on Your Top Priorities -- First...




The Failed Air End Bearings.

"My philosophy of life is that if we make up our mind what we are going to make of our lives, then work hard toward that goal, we never lose -- somehow we win out." ~ Ronald Reagan



The QSI 1000, Air End Housing (Compressor Case?)

" Another question for you - do you know what the difference between interested vs committed in achieving your life's goals and dreams? "






The far end of the compression,
this is where the clearance is set, between rotor's end and housing.







Another view of the same;
