compressor

Hello,

Can you please specify values?

What is specified value and what it gives? Probably you are looking on the printed rated current of motor. what if your compressor is of oversize for that motor?

Or as you said you repaired the compressor. probably now it give more output which leads to more current from motor.

Do you have the past data of motor or are you just talking on the basis of latest observation?

sir,

Before over hauling the compressr takes 270amps in loaded condition now it is taking 300amps in loaded condition in same motor capacity.

It (270amps) was before overhauling, what about when it was brand new? may be it was 300Amps at that time too.

Overhauling will make piston of compressor better fit with its cylinder(if you have repaired that) thet may result in consuming more current.

Just check piston fitments and make sure its not too tight. also confirm what is the actual rated current specified for motor. its should be above 300Amps if you want to operate it continuous.

I have seen it where the compressor had new rings installed on the cylinder and the installer did not file the rings to the proper size. This will greatly increase the amount of force required to move the cylinder.

What was the reason for the Rebuild?

Rebuild reason is for annual over hauling.

Hello

Did you perform any retrofit of this compressor? What about the flow, pressure, temperature after over hauling? Are some changes for this parameters?

if you have overhauled the compressor and the rated power has increased then just check your suc/ delivery valves . If the valves are not functioning properly then the power will increase and the compressor will trip

please check and revert back

Have you checked to see if your rings were installed upside down or in the correct order. Rings have a stamp on them with top stamped on them. Try running the compressor without the heads on to see if you can see any problems. Check to see your valves were installed correctly. And last of all check to see you have the correct oil in the compressor.

Also, check to see if the head gasket is thinner than the previous gasket. You may have changed your compression ratio.

Has anyone checked the WIRING

G? How about drop on the Phases?

Also check out if it is a Delta or a Y electrical system and then look at your phases.
