Kaeser Sx 6 - excessive belt wear

by Richard
(NC)

Having belt issues with a SX 6. Two sets of belts have be used in about 12 operational hours. The compressors amp load is normal and is producing air. The compressor turns freely and has no end play. The belts have been set as the factory states with the tension spring pin at the bottom. What we think is happening the sheave is taking the load on the outboard sheave face and loading only that side. The contact pattern on the sheave is indicating a heavy load on the outboard side and light load on the inboard side. THe compressor is on an hinged plate and appears to have no adjustment to allow for sheave alignment. Any suggestions would be welcome.

By eliminating loading as a wear issue, the only other issue is, as you point out, sheave misalignment.

I find it odd that you cannot adjust the sheaves.

I take it too that you have already contacted Kaeser.

If it is a design issue, you really need to talk to them again.

If you haven't got your compressor manual, you can get one by visiting: http://us.kaeser.com/Contacts_and_More/manuals.asp .

Wish I could offer a specific solution.

Tori, runs from cut in for a few minutes and then shuts off? What is the pressure reading at start and when it stops?

Could be a pressure switch problem.

Any other Sigma 12 rotary screw compressor users exhibiting the same symptoms with your air compressors?

Thanks,

Bill

Which controller?
by: Carls421

When you say its a Sigma 12, is that the Model number? Does it have a controller on it? Does it come up with any fault codes?

If it is stopping after a few minutes, it could be a whole manner of things, for example, Overheating, going in the wrong direction (If you have recently installed it)

If you have anymore info as to which compressor you have, then I might be able to help?

WHAT TYBE OF OIL USED FOR KAESER cds102 compressor

Hello Essam.

The more industrial the air compressor, the more it is critical to know what oil is recommended by the manufacturer, and to us that oil. Particularly if the compressor is under warranty.

I had a look for info for you, and found a CSD 102 compressor, but not a CDS?

I suggest, rather than using a general purpose compressor oil, which is usually find for the smaller DIY type air compressors, you contact Kaeser for their specific recommendation. You can email them at: productinfo@kaeser.com .

Cheers,

Bill

Oil For Kaeser Compressor
by: Mark Shawyer

If the unit is a CSD series compressor, there are generally 3 types of oil that Kaeser recommends:

M-460 which is a semi synthetic blend good for 2000-4000 hours

S-460 which is a full synthetic oil that is rated for 6000-8000 hrs

FG-460 which is a food grade that is limited to 2000-3000 hours

You will have to talk to a local Kaeser dealer and explain to them your hours of operation, compressor room conditions& type of business you have to get the right oil for your application.
