I am an apprentice who has been given a project to look into improving the maintenance of one of the companies hydraulic systems.
I particually want to know what is the best practice for running the pump motors. There are a number of pumps in the systems half are used on load while the rest are on standby.
Is the current thinking that running both halfs an equal amount of time (i.e. one half for a week and the other half for the following week etc) or running one half on load constantly until they show sign of decay, then bring in the standby motors or is there another method for running to increase the motor/pump reliability?
Thank you for your time!
