Hydraulic systems can be used to load, unload, lift, retract, rotate, and operate many different components. Tissue machines typically employ one or more hydraulic systems, each composed of a fluid reservoir, reservoir heaters, one or more hydraulic pumps, filtration equipment, cooling heat exchanger, distribution and return piping, valves, actuators, and instruments and controls. Strainers, filters, heat exchangers, and sometimes water-removal equipment are used to keep the hydraulic fluid clean and dry, and in the proper temperature range, in order to minimize problems and wear, and successfully operate hydraulically-actuated equipment.
