  • Sorting out vacuum-pump technology
    of such systems. Intermittent operation. A rotary-vane pump's electric motor cannot efficiently cycle on and off to break a vacuum. A vacuum valve can be added for intermittent use, but the motor must still run continuously. In such applications, multistage air-driven pumps tend to be more energy
  • Advantages of Electric Clutches When Driving Components Off a Gas or Diesel Engine
    Design ran an editorial in their August 7 edition on how Ogura's clutches are being used in the oil field industry to allow natural gas engines to cost effectively replace electric motors on pump jacks and how ideally they are suited for continuous exposed environmental conditions.

    as negative. Compressed Air and Vacuum Systems- Fig. 1 compares the basic operation of. compressed air and vacuum systems. In both systems a prime mover such as an. electric motor or gasoline engine operates an air compressor or vacuum pump,. converting electrical or chemical energy into pneumatic energy
  • Industrial Vacuum Cleaner for Glass Factory
    a plant manually or by forklift. The vacuum s 15-horsepower electric positive-displacement vacuum pump (or PD-pump) moves about 380 cfm of air at 12 inches Hg (or 162 inches of water lift). The vacuum s PD-pump can be speced to run off any 3-phase power supply 208-, 240-, or 480-volt in the US, 575-volt
  • Krispy Verification System
    system is completely self-contained on a cart, neatly packaged with the works -- air compressor, vacuum pump, electrical -- in a cabinet underneath the unit. Wires run from cabinet to junction box to the unit. Finally, a drawer containing a keypad slides out of the way when not in use. "It's very
  • Air-Powered Vacuum Helps Heavyweight Coating Company Knock Out Shocks
    the operators in a powder coating area of a metal fabrication shop after they get shocked while using an electric shop vacuum during their cleanup routine. To stop the static, the company brings in an air-powered vacuum that not only gets rid of dust, but also eliminates jumpiness in the maintenance crew
  • The anatomy of a large hydraulic power system
    . Ball valves should be equipped with limit switches that interlock with the electric-motor starters. Vacuum switches at pump inlets and pressure switches in pump cases are even more helpful. Without them, case-drain passages clog and fail while the pump is running. Hydraulic systems should have
