Hydraulic pump functions by converting mechanical power into hydraulic energy to generate flow or pressure in a hydraulic system.

• Hydraulic pump takes in fluid from a reservoir and delivers it to the rest of the hydraulic system.

• It generates flow or pressure to move the hydraulic fluid through the system.

• There are different types of hydraulic pumps such as gear pumps, vane pumps, and piston pumps.

• The pump creates a vacu...read more

MTTR stands for Mean Time To Repair, which is the average time taken to repair a failed component or system.

• MTTR is calculated by dividing the total downtime by the number of failures.

• It is an important metric in maintenance management to assess the efficiency of maintenance processes.

• For example, if a machine is down for a total of 10 hours due to 2 breakdowns, the MTTR would be 5 hours (10 hours / 2 breakdowns).
