Hydraulic drive power loss
Hydraulic drive power loss
(OP)
Hello,
I have an application that uses a hydraulic motor powered from a diesel engine.
There was a small leak on the hose connection to the pump which pretty much emptied the reservoir (pump was not used for about 2 months). The reservoir has now been topped up but the power output does not appear to have returned to normal levels. Could this just require more oil in the reservoir, or could there be an underlying problem like trapped air or something else?
Also is there any chance oil could have seeped into the flywheel/clutch plate and could this also cause a loss of power?
Thanks

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Running any pump dry, especially the higher power, higher pressure units, risks damaging some of the internals to the extent that you are fortunate the thing is still working to any degree.

I wasn't asking for (or expecting) a full breakdown report or a miracle fix, just whether I'm barking up the wrong tree or not.
I now know all are possible and can go from here. Thanks.

Also the fluid used needs to be what the pump is expecting - was it topped up with the same fluid? Hydraulic oil is quite specific. My best guess is you've caused the pump some damage and there is now some greater clearances inside the machine than there was before.
