Turboviber Vibrator
VK Turboviber TV-7
Turbine vibrators use compressed air to turn an unbalanced turbine wheel producing rotary vibration. The more unbalanced the wheel and the faster it turns the greater the centrifugal force produced. In general, properly designed turbine vibrators are much more quiet and efficient than other types of pneumatic rotary vibrators (i.e. ball or roller vibrators).

When harnessed by proper mounting of the turbine vibrator, this rotary vibration is transferred through the hopper or bin wall to the material within. As the material vibrates it is displaced from the hopper wall reducing friction and allowing gravity to restore material flow. Proper mounting also disperses the rotary vibration over a large area producing uniform material flow. Since rotary vibration is directional, material will be encouraged to flow in the direction of the rotating turbine wheel.

Applications:

  • Turboviber® vibrators operate at relatively high RPM producing high frequency vibration. They also produce large amounts of force. This makes them well suited for compacting or unloading large quantities of fine materials, such as sand or cement, from railcars, batch hoppers, or storage bins. Excellent for use with wet fine material. The high frequency excites the fine particles and the high force moves the large mass.
  • These same properties make Turboviber® vibrators highly useful for consolidating concrete. It takes this unique combination of frequency and force to remove air bubbles, disperse the large aggregates, and ensure the cement fines are evenly distributed to coat the aggregates. Proper use of vibration means less water is needed, which produces stronger concrete. Air bubble removal and even cement-aggregate distribution produces a smoother finish. Turboviber® vibrators make pouring concrete quicker and easier without harming the forms. They are commonly found on battery molds, compaction tables, tilt tables, and a large variety of forms and molds for girders, tees, columns, culverts, vaults, containers, septic tanks, concrete pipe, etc.
  • It is easy to tune Turboviber® vibrators to the material being handled. When the frequency of the vibration matches the natural frequency of the material, enhanced flow can be achieved with a minimum of force. This can be achieved by simply increasing the speed gradually (increasing the air flow) until material flow is achieved. This way you obtain the maximum result with the minimum of air consumption and vibrator wear. Once the material moves freely, the vibrator can be turned off until it is needed again.

Features:

  • Produces Uniform, Directional Flow.
  • High Frequency, High Amplitude Vibration.
  • Versatile - Easy to control force and frequency by adjusting air supply.
  • Reliable Starting - No vanes to stick.
  • Simple, Dependable - No vanes to stick, therefore starts every time regardless of mounting position. Single moving part is eccentric weight/turbine wheel assembly that rides on a single pair of bearings. Large bearings assure long service life.
  • Easy Maintenance & Repair - No vanes or cylinders. Only parts that require replacement are the long-life bearings and oil seals. No lubrication required.
  • One-Year Warranty.

Operating Requirements:

  • Filtered air. No lubrication required.
  • 70-110 PSI. 30-90 CFM.

Vibrator Selection:

  • Selection based on the weight of the material in the sloped portion of the container.
  • In general, select the turbine vibrator capable of producing a force equal to one-tenth the weight of the material when the vibrator is operating at low to medium pressure (20-40 PSI / 1.4-2.8 BAR).
  • When more than one vibrator fits, refine your selection based on the mesh size of the material. For very fine material, use the vibrator that produces the higher frequency vibration (higher rpm). For coarser material use the slower vibrator.
  • For concrete consolidation, the selection depends on the consistency of the concrete.

FOR CONCRETE CONSOLIDATION
CONSISTENCYSLUMPSELECTION
VERY STIFF CONCRETE< 0.5"Vibrator force output should be equal to 200-300% of the total concrete and form weight.
STIFF OR STIFF PLASTIC CONCRETE0.5 - 2.0"Vibrator force output should be equal to 130-150% of the total concrete and form weight.
PLASTIC OR FLOWING CONCRETE> 2.0"Vibrator force output should be equal to the weight of the concrete and form.

Accessories:

  • Manual Valves - 2-way manual ball valve used to turn the vibrator on and off for normal operation.
  • Solenoids - For remote or automated control, use 2-way normally closed solenoid valve to turn the vibrator on and off for normal operation.
  • Airline Kits - Required for trouble-free operation and long life of turbine vibrators. Includes airline filter, and pressure regulator with gauge.
  • Sirometer - Convenient, compact RPM Meter for measuring vibrator speed.
