  • Hydraulic hybrids boost fuel economy
    Innovative propulsion system enhances efficiency, cuts emissions UPS is currently road testing a delivery vehicle in which a hydraulicpropulsion system replaces the conventional driveshaft, differential, and transmission. In the series hydraulic hybrid, hydraulic pumps and motors drive the rear
  • Hydraulic Pumps
    energy from a motor or engine to fluid energy in the system. Most systems can be made to work more efficiently when something is installed in the system to allow storage of temporarily unneeded fluid delivered from the pump or compressor. In hydraulic systems, the storage device, of course
  • Hydraulic "Batteries " Save Fuel
    Accumulator-based energy recovery systems improve mobile-equipment efficiency. Hydropneumatic accumulators are widely used in industrial and mobile hydraulic systems because they provide auxiliary power during peak periods. This lets designers select smaller pumps, motors, and reservoirs
  • Five pumps power blast-hole drill
    it one of the most productive, according to company engineers. The rig's 1,500-hp diesel engine or 1,400-hp electric motor drive a custom-built gearbox that runs five pumps from Parker Hannifin's Hydraulic Pump Div., Marysville, Ohio. The pumps, in turn, power virtually the entire machine. According
  • Oceanic probes float free -- thanks to a brush-dc motor
    possible time. Optimare Sensorsysteme AG, the German manufacturer of the Nemo floats, uses a hydraulic bladder filled with oil in place of the gas bladder. An oil-filled piston acts as reservoir and pump to drive oil into the bladder at the bottom of the probe. The oil expands the bladder, displacing
  • Hydraulics & Pneumatics - Add Functionality to Hydostatic
    Hydraulic system designers are continually looking for ways to obtain broader ranges of speed and torque from a hydrostatic drive with a given pump, motors, and prime mover. The existing successful schemes an be summarized as: *Using mechanical transmission with a variety of gearing arrangements
  • Guidelines for Filtration
    Material contaminants can exist as gas, liquid or solid. A gas can either be dissolved or entrained in the fluid. A liquid, depending on its compatibility with the fluid, can be free, dissolved, or emulsified. The above types of contamination aggravate the abrasive wear in hydraulic components
  • Drive Helps Gear Dyno Keep its Cool
    ., go in highly accurate, self-cooling gear dynamometers used to test differentials for NASCAR Nextel Cup cars. The dynamometer maker, Cleona, Pa., chose electric motors and the Yaskawa drives over conventional "tractor " dynamometer designs that rely on throttled hydraulic motors and pumps for power
