I have problem during unloading we got too much noise and high temperature alarm coming and oil coming on load percentage gauge please give guide
Generally speaking, it could be two things:
1) Oil flow problem
2) Screw element problems
If the oil flow is blocked it sometimes happen that the flow becomes too low during unload running. During loaded running, this is no problem because of the higher internal pressures. Please check oil lines and oil filters.
It could also be a problem with the screw element – especially bearings that are going bad. This is sometimes especially noticeable during unload running as there forces on the screws are different (less) during unload running – allowing for more play in the bearings.
If this is the case, the screw element should be overhauld asap, to prevent further damage.
Good luck! Please let me know what you find out or if you have any other questions.
