  • Page 7: Operating Principle Of The Rotary Vane Pump

    Operating principle of the rotary vane pump Single-stage This is a volumetric pump, with a functional part composed of: • A hollow cylindrical stator with inlet and exhaust valves. rotary vane pump • A rotor mounted eccentrically inside the stator for pumping. •...
  • Page 8 Two-stage To improve the backing pressure and flowrate at low pressure, two stages are connected in series. The second is similar to the first both structurally and operationally. rotary vane pump The gases pulled in by the first stage (low pressure) are transferred to the second stage (high pressure) and discharged through the high pressure (HP) valve.

  • Page 9: Oil - Noise Limiter - Antisudback

    Oil - Noise limiter - Antisuckback Oil has several important functions in the pump: – It lubricates mechanical components (bearings, seals, rotor, vanes, etc.). – It makes moving parts relatively tight by limiting internal leakage. – It carries away the heat produced by the compressed gases. Choosing the right oil Not all oils produce the same ultimate pressure in a given pump.
  • Page 10 Anti-noise Parallel to the oil flow, there is a small orifice in the venturi tube (5), which reduces the noise level at ultimate pressure. Because of the negative pressure created at the end of the venturi tube (5), gases are entrained into the moving layers of oil dampening pump noise, allowing the fluid to become more compressible.The added gases will affect the ultimate pressure, therefore, a compromise between sound level and ultimate pressure has to be reached as follows:...
  • Page 11 Gas ballast (cont’d)  Using the gas ballast increases the ultimate pressure of the pump as well as the temperature.  The gas ballast control, located on the frame cannot be used to set the gas injection flow rate.  When the gas ballast control is open, the pump is not tight when stopped. To guarantee this tightness, install an automatic gas ballast.

  • Page 38: Oxygen Pumping

    Oxygen pumping In certain applications, mixtures containing oxygen at different concentrations, or even pure oxygen, are used. Oils of mineral origin are combustible. Exposure to pure oxygen at high temperatures may cause them to self-ignite. In addition, they are highly oxidized during pumping and quickly lose their lubricating properties.

  • Page 39: Recovery Of Oil (High Pressure Pumping And Cycling)

    Recovery of oil (high pressure and cycling) When the pump operates at high pressure, the oil heats up, becomes more fluid and is flushed out of the functional block by the gas stream. Oil losses at the exhaust are increased. If the pump only operates for a very short time at high pressure, the lubricating oil For intermittent is replaced when the pump returns to low pressure.
