The ,sizing, and selection of the engine driver is more of a challenge and the rated power of the engine is usually more than an ,electric motor, driver for the same ,hydraulic, system application. In other words, specifying a gasoline, gas or diesel engine to drive a ,hydraulic, power unit follows a different procedure than that for specifying an ,electric motor,.

2/12/2005, · For that size pump, you're looking at a 5 or 7.5HP electric motor. That's where Matt's fudge factor comes in. Your cylinder only displaces .67 gal. I'd get about a 1.5 gpm pump and run it with a 2hp motor. You should have about a 5 gal reservoir to keep the heat down. With a set-up like that, you'd have full stroke of the cylinder in about 45 seconds.

Sizing, a ,pump, is not really dependent on which technology is chosen. In all cases, it is best to start with the load and then work back through the system calculating losses at each point. Once the theoretical pressure and flow characteristics are calculated, the input horsepower requirement can be determined.

Electric, motors make sense in applications with continuous motion. An ,electric motor, is typically located close to or directly on the motion axis. In fluid power systems, the air or ,hydraulic pump, may be located remotely. Only the accumulator and control valves need to be located near the actuators.
